Introduction The supply of potable water in low resource countries has been a public health concern, with frequent water interruptions, leaving the population vulnerable to access to potable water in households, which renders the population at risk of waterborne diseases like cholera. Our objectives were to assess the household practices of drinking water collection, transportation and storage in the Fako Division of the Southwest Region of Cameroon.Methods This was a cross sectional study with a mixed method approach. Focus Group Discussions were done to get an inside of the observed practices and a quasi experimental study with education as an intervention. A total of 394 households were randomly selected and issued a pretested questionnaire. A multistage random sampling technique was used to recruit the participants in the households in the four health districts of Fako. For the quasi experiment, 50 water samples from 50 homes were tested before and after the intervention to measure the mean microbial score in stored household drinking water. A one sample t test was used to compare the mean microbial colony count at baseline and 3 months post intervention. Data were analyzed using SPSS version 23. Crude and adjusted odds ratios and confidence intervals were reported at a significance level of 0.05. Results Assessing the participants practice in drinking water collection and transportation, 273 69.3 of the participants reported public taps as their primary source of drinking water. The main alternative source of drinking water was spring 233 59.1 . More than half 56.3 of the respondents reported that they take more than 30 minutes to fetch water, done mostly by children 62.2 , and the majority 89.1 do this by trekking. Over half, 268 68 of the participants used buckets with lids, and 119 30.2 , use jerry cans to fetch water. A total of 184 46.7 reported a bucket with a lid as the water storage container meanwhile 34 8.6 and 176 44.7 stored water in a bucket with no lid and jerry cans respectively. Almost a half 180 46.9 store their drinking water for more than 2 days. The mean bacterial colony count 29.72 ± 40.07 after the intervention was significantly lower than the mean bacterial colony at baseline 71.4 ± 68.38, t 50 = 6.846, P 0.001 .Conclusion The primary source of drinking water in Fako is public tap, alternative source being a spring. More than half of the participants trek to fetch water and almost half of the participants store drinking water for more than 2 days. Intervention with health education significantly lowered the mean bacterial colony count in household drinking water.

This document provides a summary of a water and sanitation report on schools in Kanungu, Uganda. The report studied water access, quality, and sanitation in 30 primary and secondary schools through questionnaires with school staff and focus groups with students. It found that while most schools have access to a tap, breakdowns requiring alternative water sources were common and often lasted over a week. Less than 20% of schools met government water usage targets. Treated drinking water was tested and 85% showed evidence of fecal contamination, indicating treatment efforts were largely unsuccessful. Focus groups revealed problems like school-community conflicts contributed to limited water access. Maintaining hygiene and sanitation often had low priority compared to other water uses. The report concludes
1. The study evaluated the impact of an automated chlorination technology called Chlorun on providing safe drinking water in a rural Indian village called Namiligonda.
2. Baseline water quality testing found the village's surface water source to be highly contaminated with fecal coliform. Traditional intermittent chlorine treatment was unable to consistently disinfect the water.
3. The Chlorun system was installed to provide continuous 24/7 chlorination. Post-installation testing found E. coli was eliminated from the water during the study period and residual chlorine levels of 0.5 parts per million were maintained.
4. Health outcomes like incidence of diarrhea, weight gain in children, and hygiene

Microbiological dynamics of potable water under storage durationsAlexander Decker
This document summarizes a study that analyzed the microbiological quality of potable water (tap water and sachet water) from Elele, Nigeria under different storage durations. Samples were collected weekly for 10 weeks and tested for total bacterial count, coliforms, E. coli, Salmonella-Shigella, Vibrio cholerae, and fungi. Testing found that total bacterial counts, E. coli counts, and coliform counts generally increased over the 10 week storage period for tap water samples. Sachet water samples had lower initial counts that also increased during storage. Isolated bacteria included E. coli, Enterobacter, Staphylococcus, Pseudomonas, Klebsiella, and Bac
Drinking Water Quality and Sanitation Issues: A Survey of a Semi-Urban Settin...IJRES Journal
An assessment on the drinking water quality from major source (borehole) and household in a semi-urban setting in Nigeria was carried out. Structured questionnaire was administered to randomly selected households in seven zones of the municipality to determine the common method of collection and transportation, storage, and sanitation practices. Water samples collected were subjected to laboratory analyses for physico-chemical and microbial properties. The result of the physico-chemical analysis when compared against the World Health Organization (WHO) and Standard Organization of Nigeria (SON) drinking water quality benchmark revealed that the water samples were within standards for consumable water except for the presence of feacal contamination. The result revealed that before water can be totally considered safe for drinking, further treatment is required at the household level due to fecal contamination, and water safety concerns are also highlighted. The result translates to the fact that compliance assessment with standards and impact assessment studies in determining the fate of pollutants is necessary at all levels.
Determinants of household water quality in the tamale metropolis, ghanaAlexander Decker
This study assessed factors influencing household water quality in Tamale, Ghana. Water samples were collected from 250 households and tested for contaminants. The results showed that 83% of samples tested positive for E. coli, and the majority had feacal coliform bacteria present. Water source, distance to source, and water storage practices were found to impact household water quality. Those fetching water from outside sources like public standpipes were less likely to have quality water compared to those with in-home sources. On-site water treatment is needed to ensure water safety for domestic use in Tamale.
- The study tested 24 bottled water samples from brands available in Lahore, Pakistan for microbiological quality.
- Using membrane filter technique, 2 of the 24 samples (8.3%) were found to be contaminated with bacteria found in human or animal excreta and deemed unsafe for consumption.
- While most samples tested were safe, the findings emphasize that bottled waters should not be assumed safe and may require additional processing by consumers to ensure microbiological safety.

Prevalence, Diversity of Diarrhoeagenic Escherichia Coli and Associated Risk ...Babatunde Odetoyin
Abstract
Background: Diarrhoeagenic Escherichia coli (DEC) strains are common causes of morbidity and mortality worldwide. Waterborne DEC could pose a health risk to humans through domestic use of contaminated water. However, epidemiological studies on DEC in well water are scarce in Nigeria. This study determined the prevalence, diversity and factors associated with the presence of DEC in well water in Ile-Ife, southwestern Nigeria.
Methods: We assessed 143 wells for safety and a questionnaire was administered. Contaminating isolates were identified as E. coli by amplifying their 16S rRNA gene. Five diarrhoeagenic E. coli pathotypes were sought using multiplex polymerase chain reaction (PCR). (GTG)5 repetitive PCR and Shannon diversity index were used to determine isolates diversity. Multivariate analysis was used to reveal the factors associated with the presence of DEC in well water.
Results: Fifty-six (39.2%) wells were contaminated by diarrhoeagenic E. coli. Wells with dirty platforms, undercut by erosion and sited near septic tanks significantly harboured DEC (p < 0.05). There was a preponderance of Shiga-toxin producing E. coli among the isolates with 10 (17.9%) wells contaminated by multiple DEC. The DEC isolates showed 45 unique fingerprints and were divided into six clades, with an overall diversity index of 18.87.
Discussion: The presence of DEC in well water highlights the risk to human health associated with the use of untreated water. There was a high degree of genetic diversity among the isolates implying multiple sources of contamination. There is a need for periodic sanitation and inspection of wells for cracks to prevent seepages and possible outbreaks of waterborne diseases
Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

The study found lower than national averages for improved sanitation facilities (35.3-52.3% of households), lack of toilets (37-63% of households), and improved water supplies (52-60% of households). Water quality testing found E. coli present in 32-37% of household water samples, though V. cholerae was not isolated. Significant associations were found between occupation/sanitation facilities and house ownership/knowledge of oral rehydration solution preparation. Predictors of household water quality included having a toilet and improved toilet facilities. The study recommends improving water supplies, sanitation
This study examined the level of water awareness among 320 Jordanian university students. It assessed awareness in three areas: the significance of water in life, water problems in Jordan, and water conservation.
The study found a weak level of awareness about water's significance, with 57% recognizing its importance. Scientific students had higher awareness than those in humanitarian fields. Most students acknowledged Jordan's water problems but solutions focused more on government than individual actions.
Awareness of water conservation was also weak, with only 31% interested. Males had slightly lower conservation awareness than females. The study recommends increasing water-related topics in humanitarian curricula and encouraging personal conservation activities to raise awareness.
Sanitation Mapping of Groundwater Contamination in a Rural Village of IndiaKavya Prabhakar
This study analyzed groundwater samples from 50 wells in a rural village in India to assess microbial contamination. Laboratory tests found high levels of total coliform, E. coli, and other bacteria in the samples, indicating the water was microbiologically unfit for consumption. A geographic analysis using GPS and GIS mapping found that most wells were located very close to latrines (average distance of 6.44 meters), shorter than the EPA guideline of 15.24 meters. Higher bacterial counts were found in wells located closer to latrines. The study concluded that poor siting of wells near latrines was a key reason for the groundwater contamination in the village.
This project aims to improve access to clean water and sanitation in rural Cambodia. It will construct new water points and repair existing ones for 29 villages, establishing a maintenance program to ensure long-term sustainability. It will also promote better hygiene practices through community workshops and build latrines in 8 schools. This 3-year project, which complements government goals, expects to train local maintenance teams and gradually transfer responsibility to community water groups and provincial authorities to continue support after project completion.

These plans and accompanying community monitoring tools were then piloted by several organizations, including NGOs and DPHE. The results of the pilots showed improvements in water quality and sanitation. Communities responded positively and saw benefits. Based on the success, WSPs are being scaled up nationally in Bangladesh to improve water safety.
Biometric Assessment of Bacteriological Profile of Borehole Water in Relation...Premier Publishers
This document summarizes a study that assessed the bacteriological profile of borehole water from nine student hostels in relation to sewage disposal units. Water samples were tested for total bacteria counts and fecal coliform counts. Higher counts were found in samples from hostels closer to sewage units and from older boreholes. Bacteria isolated included E. coli, Klebsiella, Bacillus, Pseudomonas, Salmonella, and Vibrio cholerae. Total bacteria counts correlated with fecal coliform counts and negatively correlated with distance from sewage units. The study concludes that boreholes should be farther from sewage units and older boreholes require treatment to improve water quality.

Stakeholder Participation in Water Resource Management Drop of Lifeijtsrd
Water resources are threatened both nationally and globally due to anthropogenic activities. This puts at risk the realization of the United Nations’ Sustainable Development Goals. It is for this reason that sustainable water resource management forms part of the key global development concerns. The present study sought the participation of community as well as stakeholders in management in Kipkelion West Sub County within Kericho County in Kenya. Descriptive research design was used in this study. The study population comprised of households and water management agencies within Kipkelion West Sub County. About 394 households were randomly sampled for the study while purposive sampling technique was used in selecting 10 key informants for interviews. The study area was in Kipkelion West Sub County within Kericho County in Kenya. Household questionnaires and interview guides were used in the data collection. Although the use of water resources was found to be communal in nature, the management was left in the hands of the resource owners and water other water resources management stakeholders. The main stakeholders in the water resource management in the study area were found to be the County Government of Kericho, Water Resources Authority WRA and Kericho Water and Sanitation Company KEWASCO . These stakeholders were found to be working consultatively to manage the water resources in Kipkelion West Sub County.

The Cost and Quality of Bottled Water in Refilling Stations and Tap Water in ...IJAEMSJORNAL
This study compared the quality of tap water given by the Cabanatuan City Water District – Prime Water Cabanatuan to replenished filtered water and bottled water obtained from water refilling stations. Water samples, in particular, had been tested in the lab for microbiological, physical, and chemical quality. Parameters include heterotrophic plate count, total coliform, thermotolerant coliform/Escherichia coli, total dissolved solids, pH, and turbidity. It was found that water supplied by Cabanatuan City Water District – Prime Water Cabanatuan City is cheaper, safe, and passed the Philippine National Standards for Drinking Water of 2017 compared to bottled water samples from refilling stations. However, despite the availability of potable water provided by the city water district, it is difficult to convince the public to adopt the behavior of drinking tap water instead of bottled or refilled purified water.

This study examined the level of water awareness among 320 Jordanian university students. It assessed awareness in three areas: the significance of water in life, water problems in Jordan, and water conservation.
The study found a weak level of awareness about water's significance, with 57% recognizing its importance. Scientific students had higher awareness than those in humanitarian fields. Most students acknowledged Jordan's water problems but solutions focused more on government than individual actions.
Awareness of water conservation was also weak, with only 31% interested. Males had slightly lower conservation awareness than females. The study recommends increasing water-related topics in humanitarian curricula and encouraging personal conservation activities to raise awareness.
Sanitation Mapping of Groundwater Contamination in a Rural Village of IndiaKavya Prabhakar
This study analyzed groundwater samples from 50 wells in a rural village in India to assess microbial contamination. Laboratory tests found high levels of total coliform, E. coli, and other bacteria in the samples, indicating the water was microbiologically unfit for consumption. A geographic analysis using GPS and GIS mapping found that most wells were located very close to latrines (average distance of 6.44 meters), shorter than the EPA guideline of 15.24 meters. Higher bacterial counts were found in wells located closer to latrines. The study concluded that poor siting of wells near latrines was a key reason for the groundwater contamination in the village.
This project aims to improve access to clean water and sanitation in rural Cambodia. It will construct new water points and repair existing ones for 29 villages, establishing a maintenance program to ensure long-term sustainability. It will also promote better hygiene practices through community workshops and build latrines in 8 schools. This 3-year project, which complements government goals, expects to train local maintenance teams and gradually transfer responsibility to community water groups and provincial authorities to continue support after project completion.

These plans and accompanying community monitoring tools were then piloted by several organizations, including NGOs and DPHE. The results of the pilots showed improvements in water quality and sanitation. Communities responded positively and saw benefits. Based on the success, WSPs are being scaled up nationally in Bangladesh to improve water safety.
Biometric Assessment of Bacteriological Profile of Borehole Water in Relation...Premier Publishers
This document summarizes a study that assessed the bacteriological profile of borehole water from nine student hostels in relation to sewage disposal units. Water samples were tested for total bacteria counts and fecal coliform counts. Higher counts were found in samples from hostels closer to sewage units and from older boreholes. Bacteria isolated included E. coli, Klebsiella, Bacillus, Pseudomonas, Salmonella, and Vibrio cholerae. Total bacteria counts correlated with fecal coliform counts and negatively correlated with distance from sewage units. The study concludes that boreholes should be farther from sewage units and older boreholes require treatment to improve water quality.

Stakeholder Participation in Water Resource Management Drop of Lifeijtsrd
Water resources are threatened both nationally and globally due to anthropogenic activities. This puts at risk the realization of the United Nations’ Sustainable Development Goals. It is for this reason that sustainable water resource management forms part of the key global development concerns. The present study sought the participation of community as well as stakeholders in management in Kipkelion West Sub County within Kericho County in Kenya. Descriptive research design was used in this study. The study population comprised of households and water management agencies within Kipkelion West Sub County. About 394 households were randomly sampled for the study while purposive sampling technique was used in selecting 10 key informants for interviews. The study area was in Kipkelion West Sub County within Kericho County in Kenya. Household questionnaires and interview guides were used in the data collection. Although the use of water resources was found to be communal in nature, the management was left in the hands of the resource owners and water other water resources management stakeholders. The main stakeholders in the water resource management in the study area were found to be the County Government of Kericho, Water Resources Authority WRA and Kericho Water and Sanitation Company KEWASCO . These stakeholders were found to be working consultatively to manage the water resources in Kipkelion West Sub County.

The Cost and Quality of Bottled Water in Refilling Stations and Tap Water in ...IJAEMSJORNAL
This study compared the quality of tap water given by the Cabanatuan City Water District – Prime Water Cabanatuan to replenished filtered water and bottled water obtained from water refilling stations. Water samples, in particular, had been tested in the lab for microbiological, physical, and chemical quality. Parameters include heterotrophic plate count, total coliform, thermotolerant coliform/Escherichia coli, total dissolved solids, pH, and turbidity. It was found that water supplied by Cabanatuan City Water District – Prime Water Cabanatuan City is cheaper, safe, and passed the Philippine National Standards for Drinking Water of 2017 compared to bottled water samples from refilling stations. However, despite the availability of potable water provided by the city water district, it is difficult to convince the public to adopt the behavior of drinking tap water instead of bottled or refilled purified water.

The Impact of Digital Media on the Decentralization of Power and the Erosion ...ijtsrd
The impact of digital media on the distribution of power and the weakening of traditional gatekeepers has gained considerable attention in recent years. The adoption of digital technologies and the internet has resulted in declining influence and power for traditional gatekeepers such as publishing houses and news organizations. Simultaneously, digital media has facilitated the emergence of new voices and players in the media industry. Digital medias impact on power decentralization and gatekeeper erosion is visible in several ways. One significant aspect is the democratization of information, which enables anyone with an internet connection to publish and share content globally, leading to citizen journalism and bypassing traditional gatekeepers. Another aspect is the disruption of conventional media industry business models, as traditional organizations struggle to adjust to the decrease in advertising revenue and the rise of digital platforms. Alternative business models, such as subscription models and crowdfunding, have become more prevalent, leading to the emergence of new players. Overall, the impact of digital media on the distribution of power and the weakening of traditional gatekeepers has brought about significant changes in the media landscape and the way information is shared. Further research is required to fully comprehend the implications of these changes and their impact on society.

Comparative Analysis of Total Corporate Disclosure of Selected IT Companies o...ijtsrd
Disclosure is a process through which a business enterprise communicates with external parties. A corporate disclosure is communication of financial and non financial information of the activities of a business enterprise to the interested entities. Corporate disclosure is done through publishing annual reports. So corporate disclosure through annual reports plays a vital role in the life of all the companies and provides valuable information to investors. The basic objectives of corporate disclosure is to give a true and fair view of companies to the parties related either directly or indirectly like owner, government, creditors, shareholders etc. in the companies act, provisions have been made about mandatory and voluntary disclosure. The IT sector in India is rapidly growing, the trend to invest in the IT sector is rising and employment opportunities in IT sectors are also increasing. Therefore the IT sector is expected to have fair, full and adequate disclosure of all information. Unfair and incomplete disclosure may adversely affect the entire economy. A research study on disclosure practices of IT companies could play an important role in this regard. Hence, the present research study has been done to study and review comparative analysis of total corporate disclosure of selected IT companies of India and to put forward overall findings and suggestions with a view to increase disclosure score of these companies. The researcher hopes that the present research study will be helpful to all selected Companies for improving level of corporate disclosure through annual reports as well as the government, creditors, investors, all business organizations and upcoming researcher for comparative analyses of level of corporate disclosure with special reference to selected IT companies.

The Role of Mentoring and Its Influence on the Effectiveness of the Teaching ...ijtsrd
This paper reports on a study which was conducted to investigate the role of mentoring and its influence on the effectiveness of the teaching of Physics in secondary schools in the South West Region of Cameroon. The study adopted the convergent parallel mixed methods design, focusing on respondents in secondary schools in the South West Region of Cameroon. Both quantitative and qualitative data were collected, analysed separately, and the results were compared to see if the findings confirm or disconfirm each other. The quantitative analysis found that majority of the respondents 72 of Physics teachers affirmed that they had more experienced colleagues as mentors to help build their confidence, improve their teaching, and help them improve their effectiveness and efficiency in guiding learners’ achievements. Only 28 of the respondents disagreed with these statements. With majority respondents 72 agreeing with the statements, it implies that in most secondary schools, experienced Physics teachers act as mentors to build teachers’ confidence in teaching and improving students’ learning. The interview qualitative data analysis summarized how secondary school Principals use meetings with mentors and mentees to promote mentorship in the school milieu. This has helped strengthen teachers’ classroom practices in secondary schools in the South West Region of Cameroon. With the results confirming each other, the study recommends that mentoring should focus on helping teachers employ social interactions and instructional practices feedback and clarity in teaching that have direct measurable impact on students’ learning achievements.

This study primarily focuses on the design of a high side buck converter using an Arduino microcontroller. The converter is specifically intended for use in DC DC applications, particularly in standalone solar PV systems where the PV output voltage exceeds the load or battery voltage. To evaluate the performance of the converter, simulation experiments are conducted using Proteus Software. These simulations provide insights into the input and output voltages, currents, powers, and efficiency under different state of charge SoC conditions of a 12V,70Ah rechargeable lead acid battery. Additionally, the hardware design of the converter is implemented, and practical data is collected through operation, monitoring, and recording. By comparing the simulation results with the practical results, the efficiency and performance of the designed converter are assessed. The findings indicate that while the buck converter is suitable for practical use in standalone PV systems, its efficiency is compromised due to a lower output current.

Sustainable Energy by Paul A. Adekunte | Matthew N. O. Sadiku | Janet O. Sadikuijtsrd
Energy becomes sustainable if it meets the needs of the present without compromising the ability of future generations to meet their own needs. Some of the definitions of sustainable energy include the considerations of environmental aspects such as greenhouse gas emissions, social, and economic aspects such as energy poverty. Generally far more sustainable than fossil fuel are renewable energy sources such as wind, hydroelectric power, solar, and geothermal energy sources. Worthy of note is that some renewable energy projects, like the clearing of forests to produce biofuels, can cause severe environmental damage. The sustainability of nuclear power which is a low carbon source is highly debated because of concerns about radioactive waste, nuclear proliferation, and accidents. The switching from coal to natural gas has environmental benefits, including a lower climate impact, but could lead to delay in switching to more sustainable options. “Carbon capture and storage” can be built into power plants to remove the carbon dioxide CO2 emissions, but this technology is expensive and has rarely been implemented. Leading non renewable energy sources around the world is fossil fuels, coal, petroleum, and natural gas. Nuclear energy is usually considered another non renewable energy source, although nuclear energy itself is a renewable energy source, but the material used in nuclear power plants is not. The paper addresses the issue of sustainable energy, its attendant benefits to the future generation, and humanity in general. Paul A. Adekunte | Matthew N. O. Sadiku | Janet O.

Concepts for Sudan Survey Act Implementations Executive Regulations and Stand...ijtsrd
This paper aims to outline the executive regulations, survey standards, and specifications required for the implementation of the Sudan Survey Act, and for regulating and organizing all surveying work activities in Sudan. The act has been discussed for more than 5 years. The Land Survey Act was initiated by the Sudan Survey Authority and all official legislations were headed by the Sudan Ministry of Justice till it was issued in 2022. The paper presents conceptual guidelines to be used for the Survey Act implementation and to regulate the survey work practice, standardizing the field surveys, processing, quality control, procedures, and the processes related to survey work carried out by the stakeholders and relevant authorities in Sudan. The conceptual guidelines are meant to improve the quality and harmonization of geospatial data and to aid decision making processes as well as geospatial information systems. The established comprehensive executive regulations will govern and regulate the implementation of the Sudan Survey Geomatics Act in all surveying and mapping practices undertaken by the Sudan Survey Authority SSA and state local survey departments for public or private sector organizations. The targeted standards and specifications include the reference frame, projection, coordinate systems, and the guidelines and specifications that must be followed in the field of survey work, processes, and mapping products. In the last few decades, there has been a growing awareness of the importance of geomatics activities and measurements on the Earths surface in space and time, together with observing and mapping the changes. In such cases, data must be captured promptly, standardized, and obtained with more accuracy and specified in much detail. The paper will also highlight the current situation in Sudan, the degree to which survey standards are used, the problems encountered, and the errors that arise from not using the standards and survey specifications.

Towards the Implementation of the Sudan Interpolated Geoid Model Khartoum Sta...ijtsrd
The discussions between ellipsoid and geoid have invoked many researchers during the recent decades, especially during the GNSS technology era, which had witnessed a great deal of development but still geoid undulation requires more investigations. To figure out a solution for Sudans local geoid, this research has tried to intake the possibility of determining the geoid model by following two approaches, gravimetric and geometrical geoid model determination, by making use of GNSS leveling benchmarks at Khartoum state. The Benchmarks are well distributed in the study area, in which, the horizontal coordinates and the height above the ellipsoid have been observed by GNSS while orthometric heights were carried out using precise leveling. The Global Geopotential Model GGM represented in EGM2008 has been exploited to figure out the geoid undulation at the benchmarks in the study area. This is followed by a fitting process, that has been done to suit the geoid undulation data which has been computed using GNSS leveling data and geoid undulation inspired by the EGM2008. Two geoid surfaces were created after the fitting process to ensure that they are identical and both of them could be counted for getting the same geoid undulation with an acceptable accuracy. In this respect, statistical operation played an important role in ensuring the consistency and integrity of the model by applying cross validation techniques splitting the data into training and testing datasets for building the geoid model and testing its eligibility. The geometrical solution for geoid undulation computation has been utilized by applying straightforward equations that facilitate the calculation of the geoid undulation directly through applying statistical techniques for the GNSS leveling data of the study area to get the common equation parameters values that could be utilized to calculate geoid undulation of any position in the study area within the claimed accuracy. Both systems were checked and proved eligible to be used within the study area with acceptable accuracy which may contribute to solving the geoid undulation problem in the Khartoum area, and be further generalized to determine the geoid model over the entire country, and this could be considered in the future, for regional and continental geoid model.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

KEYWORD: Drinking water, collection, transportation, storage, Fako, Water Safety Plan (WSP) model,
Cameroon
Background
The Water Safety Plan (WSP) model is an approach
that is adopted by various countries to mitigate the
risks in water, by implementing best practices to
ensure continuous supply of safe water from the
source to the consumer [1,2] Almost every region in
the world today, have implemented the WSP. The
main reason being to “manage and control the
activities within the water chain system; implement
and identify the opportunities for low cost
improvements on operation practices that enhance
water safety; prevent water deterioration during
distribution, handling and storage in households;
improve the stakeholder communications and
collaboration within water sector and give
understanding to water users on complete water chain
and its vulnerability” [3]. However, the monitoring of
risks at household level in poor and rural households
is inadequate, although sustainable water delivery
services and provision of water that is safe could not
be guaranteed in most developing countries [4, 5].
In Cameroon, this regulation indicates government
commitment to providing safe potable water to its
communities [6, 7].It is unlikely that the focus dwells
much on the tap and not extended to the point of use.
The mitigation of risks given to these communities is
not consistent and dwells on the water source to the
tap on the street or yard, hence it is well proven that
there is a challenge of water quality access and
deterioration in the household at the point of use
which may render the treatment at the source less
reliable [8]. Due to water scarcity in some rural and
informal settlements, there is a need for the country to
shift its focus from the street tap to the household by
encouraging good water practices at domestic level. If
hazards are identified, it informs stakeholders that the
water is not potable and will become more dangerous
than its original state. The assessment of physical
parameters is also important in assuring provision of
safe water to the communities [9].
The principal health risk associated with household
water storage is the ease of recontamination during
transport and storage, particularly where the members
of a family or community do not all follow good
hygiene practice. Good hygienic measures include the
following: Careful storage of household water and
regular cleaning of all household water-storage
facilities, Regular hand-washing, especially after
defecation and before touching the drinking water
container, Water that is clean from the supply or has
been treated in the household needs to be protected
from recontaminations,[10].
The storage vessel should be placed above ground
level to restrict access by children and animals. It is
better to use a ladle that is stored permanently inside
the container; this reduces the risk of contamination
while the ladle is not in use. However, the ladle
should be used only to transfer water to a cup or other
vessel. Drinking from it directly may cause
contamination of the water [10]. Water should be
transported in a covered container, stored in vessels
that are covered and regularly cleaned and in a
separate container from other domestic water
wherever possible [10].
Through Sustainable Development Goal (SDG)
Target 6.1, countries around the world have expressed
the will to ensure drinking water is universally safe
[11-12].
Our objective therefore is to identify the practices of
drinking water collection, transportation, storage and
point of use and to carry out a quasi experiment for
mean microbial score in 50 drinking water samples
from 50 households in Fako Division, Cameroon.

METHODS
STUDY AREA
FIGURE 1: MAP OF FAKO, SOUTH-WEST REGION. CAMEROON [13]
STUDY DESIGN:
We conducted a cross sectional study design to ascertain the practices of the study population regarding water
management from point of collection through storage and point of final consumption. We used a blend of
qualitative and quantitative methods. For the qualitative method, we conducted three Focus Group Discussion
(FGDs) with members of three Health districts in our study area. A standardized questionnaire from previous
studies was pretested and modified [14-15]. Variables considered were: source of drinking water, distance to and
from point of collection, which family member/s is involved to fetch drinking water, mode of transportation,
mode of storage and duration of storage and finally, point of use treatment. It was pretested in Kumba. In the
field, the study was introduced to the respondents by the interviewer and after a signed informed consent form;
the questionnaire was presented to the respondent. Those who could neither write nor read English had their
questionnaires read for them by the interviewer in pidgin or French or dialect. The first section of the
questionnaire was socio-demographic characteristics; age, sex, nationality, educational level, marital and
employment status and type of house. The second section was aimed at collecting information on self-reporting
aspects of respondents’ of sources of drinking water collection, transportation, storage and point of use. A
probability proportionate to size was used to get the total number of participants from each community involved,
after a multistage random sampling to get the number of communities from each town in Fako (Fig 2).

Intervention through health education
For the quasi experiment, we collected drinking water samples from 50 randomly selected households and
calculated mean total bacterial colony count. Then used an intervention (education on good practices of drinking
water collection, transportation and storage), for three months and tested samples from same households at
baseline and calculated the mean bacterial colony count post intervention. To test the water samples, drinking
water collected at households were taken to the laboratory within 8 hours. Plate Count Agar (PCA) (Liofilchem,
Italy) was prepared following manufacturer’s instruction and allowed to solidify on a flat vibration-free work
surface. Decimal dilutions of the water samples were prepared in sterile peptone water up to 104
dilutions.

Approximately 0.1ml of well mixed diluted samples each was aseptically inoculated on to the PCA agar surface.
Using a sterile spreader, the inoculums were evenly distributed over the surface of the medium. Plates were
incubated aerobically for 24-48 hours at 37ºC.After incubation, the plates containing between 30-300 colonies
(quick visual appreciation) were selected and their respective dilution factors noted. The colonies were counted
from these plates, and the following formula was used to calculate the CFU/ml using the formula below [17]:
Bolifamba community was purposively chosen for intervention, following its consistent highest microbial load
in drinking water at household level in the dry and rainy season [13]. We randomly selected 50 households and
did a before and after study with education on hygiene and sanitation. A multistage random sampling technique
was employed. Five quarters were randomly selected from the 11quarters in Bolifamba. A probability
proportionate to size was used to select 50 households from the 5 randomlyselected quarters in Bolifamba. From
the 50 households, we collected 50 samples of drinking water containers before and after health education. We
collected baseline point of use drinking water samples for laboratory analysis. We administered health education
talks on water management from catchment to point of use (attitude and practices on water collection,
transportation, storage and point of use).The content of the health education talk comprised the following; Stop
defecating in drinking water sources, change stored water at most two days, wash storage containers at least
twice a week, elevate drinking water storage containers on a slap and not on the floor, use of jar to scoop
drinking water and not drinking cups, cover drinking cups.
We did this for 2 months on weekly basis, and then we decided to continue with SMS for a month as the
community became unstable. We sent SMSs every Tuesday, Thursday and Saturday at 6am and 5pm as we
observed that these are the peak periods when drinking water was fetched. Below is the flow chart for the
intervention with education on hygienic practices (Figure 3).

Overall proportion of Fako community, with good practice towards water collection and transportation,
2018.
In determining the overall percentage of participants with good and poor practice towards water collection, and
transportation, the questions on the questionnaires were scored. Close to three quarters 288(73.2%) of the
participants’ had good practice towards water collection and transportation respectively.
We observed the practice of community members of mile 2, Limbe entering with feet and dipping of drinking
water containers in open springs to fetch drinking water (Figure 6).

Practices on Water Storage and Point Of Use in Fako, 2019
Concerning participants practices toward water storage and point of use,329(83.1%) of the participants reported
that they placed their drinking water containers on the floor meanwhile those who placed their drinking water
containers on the slap constituted 67(16.9%) of the study population. As to how water is collected for drinking,
68(17.9%) of the participants said they drank their water directly from the bottle, 122(30.8%) said they carried

from drinking jar to cup before drinking, whereas more than half 202(51.5%) said they used cup placed directly
on bucket to drink water. As concerns the position in which drinking cup were kept, 185(46.7%) of the
respondents placed their drinking cups on the drinking bucket whereas 171(43.7%) placed their drinking cups in
an open basket in the kitchen and just 38(9.6%) placed their drinking cups on a tray covered with cloths. As to
whether, the storage containers are routinely washed, 342(86.4%) agreed that these storage containers were
routinely washed meanwhile 50(12.6%) said these storage containers were only washed sometimes and not
routinely (Table 5).

Based on the findings, we carried out two homogenous FGDs to have detail explanations on the practices of
household drinking water management. The first with women and the second with youths.
In our findings, a vast majority of more than three quarters of the study participants had good perception of
sources of drinking water.
“The water has no odor, no taste and it’s very clear and clean. We were told by some whites that we should not
add chlorine in our reservoir because our water is of good standard”.(Participant number 3 of FGD 2)
“At first we used to treat the water from our catchment. This decision for not treating the water from the
drinking water catchment was adopted because they did not master the dose of chlorine in water treatment;
hence the chlorinated water had an odor due to probably an overdose”.(Participant number 2 of FGD 1)
It was also observed that though more than three quarters of the community members of Fako said they routinely
wash their drinking water containers, some members had these to say;
‘As for me, we only wash our containers when we realized coloration at the sides of the jerrycan. (Participant
number 1 of FGD 2).
‘Sometimes we realize our storage containers are dirty only when by chance it’s taken outside, because
habitually, we simply refill fresh water carried from the drinking water source by our children. Participant
number 1 of FGD 1).
‘I usually wash my drinking water containers with sand or soap each time I realize the sides of the containers
are stained with some greenish substances. At times we can’t fully have access to all the surface areas of the
jerrycan, especially the upper section of the jerry cans, even with the introduction of a sponge aided with a
stick’. (Participant number 3 of FGD 1).

Only closely more than a quarter of the community members of Fako use drinking jars to serve drinking
water to cups.
‘We use the drinking cups to scoop drinking water from storage containers. We usually instruct our younger
siblings not to use these cups with dirty hands, which most often it’s difficult because they usually drink water
intermittently when playing’(Participant number 2 of FGD 2).
‘Close to half of the community members of Fako placed their drinking cups on the drinking buckets’
‘We usually place our drinking cups in an open basket in the kitchen. We place ours on top of the drinking
bucket’ (Participant number 2 and 3 of FGD 2).
Closely half of the community members of Fako store their drinking water for more than three days
‘We drink stored drinking water till we have the next flow of water which may take sometime up to a week’
(Participant number 4 of FGD 1).
Quasi experiment with education as intervention in Bolifamba community
A total of 50 samples from 50 households were collected at baseline and after 3 months of health education, 50
samples from same households were collected and laboratory analysis done to determine the total bacterial
colony count .Out of the 50 samples at baseline, growth occurred on 43 samples whereas growth occurred in 39
of the 50 samples post intervention. A one sample t- test was used to compare the mean total bacterial colony
count at baseline and 3 months post intervention. The mean total bacterial colony counts (29.72±40.071CFU/ml)
after the intervention was significantly lower compared to baseline (71.4 ± 68.378, t (50) = 6.846, P < 0.001)

Discussion:
Most communities in Fako are not accessing
sufficient water for all domestic uses and so become
reliant on alternate sources (mostly springs and
boreholes) [18].
Where the primary water source is not consistently
available, the safety of drinking water in the
community is compromised. The inability of the lone
national utility body to provide consistent drinking
water supply brings a lot of uncertainty to the health
risks of the communities, when other unmonitored
alternative (spring) water sources are used. In our
findings, a vast majority of more than three quarters
of the study participants had good perception of
sources of drinking water. However contrary to [19],
where in the study, the participants perceived their
sources of water have low quality ,hence treat their
drinking water before usage whereas in our findings,
the community members instead perceive their
sources are of good quality hence requires no
treatment which is in collaboration with [20]. From
the FGDs, we got information that, “the water has no
odor, no taste and it’s very clear and clean. They were
told by some whites that chlorine should not be added
in the reservoir because the water is of good
standard”. When a water committee personnel in
Bolifamba community was approached, he said “this
policy was adopted because they did not master the
dose of chlorine in water treatment, hence the
chlorinated water had an odor due to probably
overdose”. Although there is a general belief in the
safety of spring water in Fako because it is clean and
clear, a study carried out revealed that the springs
water are vulnerable to contamination due to
anthropogenic activities around the drinking water
catchments [13]. These therefore makes the water not
very fit for drinking purposes according to WHO
standards as close to half of the catchments harbor
microbes and traces of phosphates in the rainy season
due to leaching of fertilizers from farming around
[21-22]. Drinking water even from an improved
source collected with some unorthodox practices (Fig
6) showing participants entering with feet and dipping
of containers in open spring source, which can likely
contaminate the drinking water fetched, can expose
the safe water to contamination [21].
According to WHO guidelines for drinking water,
water collected with roundtrip more than 30 minutes
has the likelihood of contamination. In our study,
56.3% use more than 30 minutes roundtrip and done

mostly by children (62.2%) ,similar to [23-27],where
Women and children, in particular have to travel long
distances far from their households looking for water.
There are salient reasons for this; the population of
Fako has out grown the water storage tanks of the
water utility company and there has been no
expansion of the tanks for decades. We observed
some filtration beds out of use thereby reducing the
volume of water filtered per hour. All of these leaves
CAMWATER with volume of water which is not
commiserate with its population it serves. The only
option is to ration distribution either limiting the
hours of flow per day and sometimes skips days
before the next flow. This leaves the populations that
fetch drinking water from public stand taps
sometimes punctuated with low pressure to queue for
hours, some fight over drinking water containers and
will sometimes not have the opportunity to rinse these
drinking water containers with the likelihood of
contamination. Our results show that 30% of our
participants use jerry cans to fetch water. Jerry cans
are difficult to wash, as they have a narrow spigot. It
is difficult to realize it’s even dirty as such the
likelihood of contamination [9, 28]. Consequently, we
observed bio-film of microorganism adhere by the
sides of the jerry cans used to fetch and store drinking
water. From our results close to half (46.7%) of our
study participants store their drinking water in
buckets. Studies have shown that water stored in wide
mouth containers are liable to contamination [20], as
children frequently with the ladle dip their dirtyhands
in the drinking water exposing it for contamination.
This storage is considered a challenge and an
opportunity at the same time. There is therefore the
possibility of recontamination of drinking water
between source and point-of-use, thereby exposing
the household members to water borne diseases like
cholera ,similar to the studies in Nigeria[29-34].
We also observed that almost a half of the
participants 180(46.9%), practice storing drinking
water for up to 4-7days to secure availability of
drinking water before the next water flow. From the
FGD, Participants said “sometimes water flows at
very odd hours (midnight or between 1:00 am –
3:00am), in some communities according to schedule
or sometimes skip 2-3days or weeks”. “We are
therefore most often, bound to store drinking water
till the next flow”. Drinking water stored above at
most three days predisposes it to re-contamination
[25, 35]. These results are similar to that of a study
done in Sub- Saharan Africa and Senegal, where the
drinking water quality changed from catchment to
consumer in the rural area indicating higher
contamination of total coliform and E. coli counts in
container water at household compared to the sources
[1, 29, 36-39].
From our study, a majority of the households
329(83.5%) placed their drinking water containers on
the floor. Some 185(46.7%) of the participants,
expose drinking cups either in a basket in the kitchen
or on slaps and on the drinking containers, and 201
(51%) of our study participants dip directly in the
storage containers these exposed cups in drinking
water. These practices predispose stored drinking
water to contamination or re-contamination through
insects and dust during the day and rodents like rats
and cockroaches during the night. This is similar to a
study by [40], where unhygienic practices
predisposed stored drinking water to contamination.
Following the gaps noticed in the field in the
practices of drinking water collection, we decided to
carry out an intervention with education to scale up
on good practices of drinking water collection,
transportation and storage. Environmental health
education on safe storage of water and treatment are
amongst some of the household water safety
management that has been proven to curb the
continuation of outbreaks in developing countries
[41]. After education for three months, the mean
bacterial colony count was significantly lower. This
shows that continuous education on good practices of
drinking water management at household have a
significant impact on the quality of drinking water in
our intervention community. This is similar to a study
in South Africa where continuous education arrested
a cholera epidemic [24].
Conclusion:
The main source of drinking water in Fako is public
tap 273(69.3%), alternative source being spring
233(59.1). More than half of the participants
221(56.3%) trek to fetch water and almost a half
180(46.9%) store water for than 3 days. Intervention
with health education significantly lowered the mean
bacterial colony count in household drinking water.
The institution of an integrated water safety plan
including all stakeholders to manage or monitor
drinking water from sources of collection,
transportation, storage and point of use is paramount.
Since it might be difficult to approach the policy of
monopoly of CAMWATER that supplies potable
water in Cameroon, to mitigate the effects of frequent
drinking water interruption and unpredicted
community water schedule of tap water flow by the
lone water distribution water agency, continuous
health education on good practices and the use of
point of use water purification agents could help
improve on the quality of water used at household
