While source protection is mandatory for public water systems, local land use control requires cooperation from counties and municipalities through ordinances.
ASSESSMENT OF WASTE WATER TREATMENT IN CANAANLAND, OTA, OGUN STATE, NIGERIA.O...Felix Oginni
Effluent from a sewage treatment plant in Covenant University, Canaanland is made to pass through a series of constructed wetland before discharging into a gully that drains into River Iju (also known as Atuara). This river is used as a source of drinking water and also provides food in form of fish for hundreds of thousands of people downstream and eventually enters the lagoon, some 60km away. Effectiveness and adequacy of the wastewater treatment facility in place was assessed in order to improve sanitation within this watershed, thereby alleviating environmental challenges in this coastal region of Nigeria. Waste water is gravity drained to the southwest portion of the campus where the solid is removed and the liquid is allowed to flow through six sets of constructed wetlands, each with four chambers. Within each chamber are water hyacinth plants put in place to remove nutrients from the waster water.
A quick survey of the facility shows the system to be effective in reducing and removing solids and dissolved solids from the waste water. The pH ranged between 6.6 and 6.8, conductivity from 530 to 600, and total dissolved solids (TDS) ranged from 360 – 400 ppm. The data obtained indicate that some modifications need to be made as the waste water treatment system is not very efficient in reducing the amount of TDS and nutrients. The flow rate is considered to be very high from cell to cell, thereby not allowing time for the plants and microbes to reduce the TDS. It is suggested that some method be devised to slow down the flow rate to allow the plants and microbes to work on reducing the TDS. Parameters also also considered included DO, E. Coli. Nitrate and Phosphates.

Water Pollution Control for Mandalay KanDawGyi Lake by Natural Treatment Systemijtsrd
This paper emphasized on "Water Pollution Control for Mandalay KanDawGyi Lake by Natural Treatment System". KanDawGyi Lake is used for wastewater collection. It is situated in ChanMyaThaZi Township, Mandalay and near the AyeYarWaddy river. Residential, commercial and industrial area are existed surrounding the KanDawGyi Lake. Water from human activities such as cooking, bathing, washing and septic tanks effluent is discharged into drains by gravity flow without treatment. Average six million gallons of wastewater discharged from Mandalay City area flow into KanDawGyi Lake passing through ThinGaZar creek daily. So, lake water has been contaminated by domestic wastewater. This has resulted detrimental effects on the ecosystem. Water in recreation center should be aesthetically pleasing and essentially free of toxicants and pathogenic organisms. Seven collection points such as entrance, east of north side, south east of north side, south of north side, water fountains, PyiGyiMon barge and exit of KanDawGyi Lake are chosen to collect the wastewater sample. The water quality of KanDawGyi Lake is evaluated by various parameters such as temperature, turbidity, suspended solids, dissolved solids, pH, total alkalinity, total hardness, biochemical oxygen demand, dissolved oxygen, chlorides, total solids and bacteria. According to test results, alkalinity, chlorides, dissolved solids, suspended solids, and total solids are uncertified. Therefore, in this paper wetland design of natural treatment system is used at the entrance of the lake to control the water pollution.

This document presents research on approaches to mitigate pollution from the herbicide MCPA (2-methyl-4-chloro-phenoxyacetic acid) in water catchments used as drinking water sources. The research monitored MCPA concentrations spatially and temporally in an agricultural catchment in Ireland that supplies drinking water. Key findings include: MCPA concentrations exceeded drinking water limits and persisted in the system; concentrations increased downstream; and concentrations correlated positively with improved grassland and negatively with rough grazing land use. The research demonstrates the need for enhanced monitoring and questions the sustainability of certain land uses like improved grassland near drinking water sources.

Rain Water Harvesting and Impact of Microbial Pollutants on Ground Water Rese...IJERA Editor
Developing countries are under heavy stress due to continuous depletion of ground water reserves. The urban
areas are developing and growing very fast due to population growth, increase in commercial and trade
activities, national and international tourism development as trade. The local migration of rural population due
to better job opportunities. Civic amenities are also the reason for population explosion in urban areas and thus
there is increase in the demand of basic needs like water, shelter and power. Due to the overall consumption of
water in urban and rural areas which has increased many fold in the recent past, causing depletion of water subsurface
reserves due to difference in natural recharge of reservoirs and the corresponding water demand. The
ground water is an integral part of the environment and there has been a lack of adequate attention to water
conservation, water use and reuse, ground water recharge, and ecosystem sustainability. To meet with the
challenge of under ground water shortage, lowering level of water table, efforts are being made to recharge the
aquifer system by the Rain Water Harvesting (R.W.H.). This noble act needs serious thought and follow up to
achieve the aim of recharging ground water free from pollutants like pesticide, bacteria and seepage causing
infection and pollution of the existing pure source of potable water. A study has therefore undertaken to assess
the possible bacterial intrusion through the rain water penetration at the deeper water bearing aquifers.
The Effluent Quality Discharged and Its Impacts on the Receiving Environment ...Agriculture Journal IJOEAR
The study evaluates the performance of Kacyiru Sewage Treatment Plant and its effluent impacts on the receiving wetland. Influent and effluent wastewaters as well as receiving wetland water qualities were measured from April to September 2019, at Kacyiru estate. The average removal efficiency (%) of the parameters such as TN, TP, COD, BOD 5 were recorded as 46.57; 61.49; 50.51; 66.79 respectively. The parameters such as pH, TDS, temperature value, were recorded within the prescribed limit of Rwanda standards for domestic wastewater discharge. The other parameters such as NTU, TN, TP, TSS, BOD 5 and Fecal coliforms were not complying with National standards requirements for domestic wastewater discharge. The finding showed that the excess nutrient observed may present potential sources of pollution in wetland and decrease the oxygen levels which affect the water living organisms. The discharged effluents contain microbes which can negatively devastate the receiving environment, thus the effect of discharged wastewater on environment is significant.

Analysis of Water Quality Using Physico-chemical Parameters of Mula-Mutha Riv...ijtsrd
We wants to present an extensive work on physico-chemical parameters of water samples of Mula-Mutha river at Pune (Maharashtra). Water samples under investigations were collected from Khadkwasla dam to Sangam Bridge during pre monsoon (April “ May2016) monsoon (July “ August2016) and post monsoon (October “ November2016) seasons. The observed values of different physico-chemical parameters like pH, DO, BOD, COD, Chloride, Nitrate, Sulphate, Calcium, Magnesium and Hardness, etc. of samples were compared with standard values recommended by world health organization (WHO). The Mula-Mutha River water in Pune had deteriorated in quality. Its biological oxygen demand, an indicator of organic pollution, has risen to over 30 mg/l, more than ten times the permissible limits for bathing. Municipal Corporation is currently supplying water sufficient for the projected population. More water means more sewage, beyond the quantum its sewage treatment plants can treat. As a result there is greater pollution loads discharged in to the Mula-Mutha, two rivers that confluence within city limits and serve to flush away Punes excreta. All the physico - chemical parameters for pre monsoon, monsoon and post monsoon seasons are within the highest desirable or maximum permissible limit set by WHO except some of the parameters like DO, BOD,COD, chloride, calcium, magnesium and hardness.

Water quality can be assessed through various physical, chemical, and biological indicators. It depends on factors like geology, ecosystem, and human activities. Standards are set based on intended uses like drinking, industrial, or environmental. Water is sampled and tested using on-site or laboratory methods to monitor these indicators. Maintaining adequate water quality is important for public health and ecosystem protection.
This document evaluates the use of ultraviolet (UV) radiation and ozone for disinfecting primary municipal wastewater effluents. Experiments tested different ozone concentrations and UV fluencies at varying pH levels. Ozone doses near 20 mg/min achieved 72-78% removal of fecal and total coliforms, and removed up to 36% of chemical oxygen demand (COD). UV achieved over 80% inactivation of bacteria. Both treatments were most effective against bacteria at pH levels other than 7. UV treatment had lower energy requirements than ozone treatment. The study demonstrates the potential for UV and ozone processes to generate safely reusable or releasable effluents from primary wastewater treatment.

An Assessment on Drinking Water Quality and Management in Kakamega Municipalitypaperpublications3
Abstract: Drinking water must be free from components which may adversely affect the human health. Such components include minerals, organic substances and disease causing microorganisms. A large portion of the population in urban areas in developing countries suffers from health problems associated with either lack of drinking water or due to the presence of microbiological contamination in water. This research was conducted in Kakamega municipality with a broad objective to conduct assessment of water quality and management in Kakamega municipality. The Specific objective was to determine the chemical water quality parameters in water and to evaluate the management practices on water in Kakamega municipality. Four water quality parameters; two physical and two chemical were tested from the samples collected for this research work. Sampling technique was purposive where water samples from water sources and distribution points in densely populated areas of Kakamega municipality were taken. Data collection instruments that were used included sterilized bottles to collect water, delivery to the laboratory within six (6) hours of collection for reliable results and data quality control was achieved through immediate entry in the pre-designed data form. According to the results pH values at all the sources and house connections are well within the WHO desirable limit of 6.50-8.0. The sample from Sichirai had a pH of 7.8 that was the highest as compared to an Isiukhu river that had 6.6 pH. The samples from Isiukhu river, Savona Island River, fishpond at bridge and Shikhambi spring showed more than 5 NTU. The researchers recommended for water surveillance in Kakamega municipality in order to ensure consumers have safe water free from agricultural and industrial chemical pollution.
The document discusses India's efforts to provide safe drinking water to its population. It notes that in 1975, over 1 billion people globally lacked access to safe water. In response, India developed various five-year plans from 1980-1997 to expand access, with the goal of supplying safe water to all rural villages. Key aspects of ensuring water safety discussed include water quality standards, testing for contaminants, monitoring programs, and strategies like water treatment and sanitation inspections. The document also examines health impacts of contaminated water and international targets for access to improved water sources.
Floating treatment wetlands are proposed to improve water quality in Beira Lake in Colombo, Sri Lanka. Studies have found the lake water to have high levels of nutrients, bacteria, and other pollutants that are causing eutrophication. Floating treatment wetlands would help remove these pollutants from the water naturally through bacterial activity and plant uptake without using chemicals. The wetlands provide habitat for microbes and plants to purify the water by absorbing nutrients and increasing oxygen levels. This natural water treatment approach could help restore the lake's ecosystem functionality over time.

Abstract: Drinking water must be free from components which may adversely affect the human health. Such components include minerals, organic substances and disease causing microorganisms. A large portion of the population in urban areas in developing countries suffers from health problems associated with either lack of drinking water or due to the presence of microbiological contamination in water. This research was conducted in Kakamega municipality with a broad objective to conduct assessment of water quality and management in Kakamega municipality. The Specific objective was to determine the chemical water quality parameters in water and to evaluate the management practices on water in Kakamega municipality. Four water quality parameters; two physical and two chemical were tested from the samples collected for this research work. Sampling technique was purposive where water samples from water sources and distribution points in densely populated areas of Kakamega municipality were taken. Data collection instruments that were used included sterilized bottles to collect water, delivery to the laboratory within six (6) hours of collection for reliable results and data quality control was achieved through immediate entry in the pre-designed data form. According to the results pH values at all the sources and house connections are well within the WHO desirable limit of 6.50-8.0. The sample from Sichirai had a pH of 7.8 that was the highest as compared to an Isiukhu river that had 6.6 pH. The samples from Isiukhu river, Savona Island River, fishpond at bridge and Shikhambi spring showed more than 5 NTU. The researchers recommended for water surveillance in Kakamega municipality in order to ensure consumers have safe water free from agricultural and industrial chemical pollution.
The document discusses India's efforts to provide safe drinking water to its population. It notes that in 1975, over 1 billion people globally lacked access to safe water. In response, India developed various five-year plans from 1980-1997 to expand access, with the goal of supplying safe water to all rural villages. Key aspects of ensuring water safety discussed include water quality standards, testing for contaminants, monitoring programs, and strategies like water treatment and sanitation inspections. The document also examines health impacts of contaminated water and international targets for access to improved water sources.
Floating treatment wetlands are proposed to improve water quality in Beira Lake in Colombo, Sri Lanka. Studies have found the lake water to have high levels of nutrients, bacteria, and other pollutants that are causing eutrophication. Floating treatment wetlands would help remove these pollutants from the water naturally through bacterial activity and plant uptake without using chemicals. The wetlands provide habitat for microbes and plants to purify the water by absorbing nutrients and increasing oxygen levels. This natural water treatment approach could help restore the lake's ecosystem functionality over time.
Application of Source Water Quantity and Quality Model to Dongshan PeninsulaeWater
Lake Tai is the third largest freshwater lake in China, bordering Jiangsu and Zhejiang provinces,
providing water to 30 million residents. A severe algal bloom in 2007 led to the development of the
Lake Tai Master Plan, launched by the National Development and Reform Commission (NDRC), to
improve nutrient management in the basin. Under a joint Australian China Environmental
Development Project, the Australian eWater Source Integrated Modelling System (IMS) was applied
to model water quantity and quality for a pilot area on the Dongshan Peninsula in the Lake Tai Basin.
Source is a powerful modelling platform for environmental management which can integrate many
physical processes and human impacts, successfully applied in over 70 basins across Australia.
The document discusses the rejuvenation of lakes, using the Bellandur Lake in Bangalore, India as a case study. It describes how the lake became highly polluted due to untreated sewage and industrial effluents. This caused foam and fires on the lake. Authorities have taken measures like removing silt, treating sewage, banning dumping, and fining polluters to restore the lake. The rejuvenation of lakes overall helps with water security, fishing, livestock, and groundwater recharge.

Artifi cial wetlands are useful for wastewater treatment; however, relatively little is known of the effects of sewage on artifi cial wetland microbial community structure. Therefore, we assessed the effect of municipal sewage on microbial community diversity in surface water throughout an artifi cial wetland (Xiantao artifi cial wetland) treating municipal sewage. We analyzed the relationship between physicochemical parameters of surface water (i.e., Chemical Oxygen Demand (COD), Total Nitrogen (TN), Total Phosphorus (TP), and
NH4+-N) with microbial community structure (Illumina MiSeq sequencing followed by abundance indices). The results showed that the total microbial community in surface water was signifi cantly correlated with COD, TN, TP, and NH4
+-N (r = 0.764, 0.897, 0.883, 0.839, P < 0.05). In addition, the most abundant taxa were significantly correlated with COD (r = 0.803, P < 0.05). The relative abundance of rare operational taxonomic units in the more purifi ed water farther downstream was higher than in the polluted area, suggesting that rare groups were more sensitive to physicochemical parameters than abundant groups, and that the abundance of some bacteria could indirectly indicate the degree of aquatic pollution. Our results indicate that the responses of microorganisms in artificial wetlands to environmental conditions should be considered to ensure efficient treatment.
India faces major water quality issues due to overexploitation of its water resources and pollution from various sources. The Water (Prevention and Control of Pollution) Act of 1974 established standards for industrial and domestic wastewater effluents and requires polluters to obtain consents. National monitoring programs have identified numerous polluted water bodies across India impacted by pathogens, salinity, toxicity and other pollutants from domestic sewage, industrial wastewater, agricultural runoff and other sources. Programs such as the Ganga Action Plan and National River Action Plan were launched to restore water quality in major rivers.
The document discusses various sources of water pollution in India including agricultural runoff, industrial waste, and city sewage. It notes that 39% of water pollution comes from agriculture, 12% from industry, and 10% from cities. It also discusses solutions to reduce water pollution such as improving sewage treatment, preventing nonpoint runoff, reducing toxic pollutants, and practicing the four R's of resource use.

- Climate change and global changes threaten to exacerbate water scarcity and stress
- Improved governance, education, participation, and sustainable management approaches are needed to address these challenges
This document summarizes a study on microcystin levels in raw and treated municipal drinking water sources in Alberta. Microcystin is a toxin produced by some cyanobacteria (blue-green algae) that can be harmful to human health. The study analyzed water samples from 18 municipalities over 10 weeks and found microcystin present in 67% of raw water samples, with concentrations up to 14.8 μg/L in some sources. Microcystin was detected less often and at lower levels in treated water, indicating conventional treatment removes some toxin. All samples complied with Health Canada guidelines. The study recommends further sampling of rural communities to fully evaluate microcystin occurrence in municipal surface drinking water supplies.

The document summarizes a study that was conducted to determine sources of water pollution in Appiakrom community, Ghana. The study examined a dam, pond, and two boreholes used by the community. Laboratory analysis of water samples found that the dam, which supplies water to the district, had been polluted by anthropogenic activities. The rusty nature of one borehole was attributed to underground parent materials. The pond interfaced with the dam, and pollution could flow between the two sources. The authors recommend blocking channels between the pond and dam, and practicing zero-fertilizer farming near the dam to reduce pollution.

Abstract
This research's main purpose is to analyze the cost incurred for the nitrate contamination in the drinking water. The study focuses on the detail investigation for the health effect because of contact of nitrates in the underground reserves at “San Joaquin Valley”. This report provides detail information about the far-reaching effect of this contamination on the environmental well-being and economic vitality. The major effect of this issue is one of the low-income populations and Spanish oriented residents. San Joaquin Valley is highly contaminated due to the existence of nitrate. It is observed that most of the Californian” always take it forgiven the potable water is easily accessible. San Joaquin Valley has many communicates and agriculture areas. This nitrate contamination has a strong impact on drinking water as well as agriculture land. It is also observed that the drinking water which is served in the homes and schools is also highly contaminated. This contamination has an adverse impact on the overall health of the population in San Joaquin Valley. At the same time, it will also affect the environment along with agriculture. The nitrate contamination is very high as it leads to bring lots of problems for the infants as well as the older population. The focus of this research is to develop the clean water by using the method of cleaning nitrate contamination the results from each method will be analyzed in order to provide the most relevant method. Introduction
My main interest in research is in “Environmental Engineering”. The reason behind the selection of this field is my interest, i want to provide my services in order to make the planet batter. There are many issues faced by the earth which are still not investigated. Water is one of the basic needs of people. But it is also the fact that many people are getting water even for their drinking purpose. A research conducted by Pacific Institute” titled “The Human Costs of Nitrate-Contaminated Drinking Water in San Joaquin Valley” provides several evidences for the nitrate contaminations in the consumable water. Alone in San Joaquin Valley, 63% of the individuals are not getting water for drinking purposes. The groundwater in San Joaquin Valley is extensively contaminated with nitrate. During recent times, most of the world has been subjected to contaminated drinking water. According to the research contrite by Harter that 63% of the water in the valley is not acceptable for the drinking. The water is not usable for drinking purposes as it containsa large amount of “Pesticides, Arsenic, Nitrate, and Uranium”. At the same time, the communities using this water are also facing lots of health issues.
The nitrate has been developed from the nitrogen compound which is excreted from the industries. Nowadays, industrial waste is one of the common issues faced by the environment. As the airborne nitrogen is given off from the industries as well as the automobile it leads to cause l ...
This document analyzes upgrading the Ashbridges Bay Wastewater Treatment Plant to tertiary treatment in order to reduce nutrient loads discharged into Lake Ontario. It discusses the plant's current secondary treatment processes and effluent quality. Tertiary treatment technologies are compared, with denitrifying filters identified as the best option due to their relatively small footprint and high removal rates of nitrogen and phosphorus. Implementing tertiary treatment could significantly reduce nutrient loads into Lake Ontario if adopted by all plants discharging into the lake, but each plant would need to lower effluent nutrient limits and have sufficient space for the required tertiary processes.

Great power rivalry is accelerating in the economic domain as states view economic interdependencies as vulnerabilities and gear up for competition through new means of economic intervention. This is shifting the global economy from market capitalism toward more strategic and state-directed capitalism. States are increasingly using their economies as strategic weapons through sanctions and other policies. The global economy is becoming fragmented as economic networks decouple and competing spheres of influence emerge, potentially leading to a new Cold War dynamic or "balkanization" of the global economy. Western sanctions against Russia over Ukraine are having significant economic effects on both Russia and the global economy through commodity market disruptions and inflationary pressures.
The document discusses the economic impacts of the war in Ukraine. It notes that while global activity was picking up, confidence has declined due to the war. Russia is facing high inflation and a sharp drop in commercial links. Commodity prices have surged since the war began. Inflationary pressures are broadening in many countries. The war is weakening global growth and increasing inflation. A large refugee crisis is also underway in Eastern Europe as many Ukrainians flee the war.
The document discusses the impact of the Russian war in Ukraine on the Finnish forest sector. It finds that Russian wood imports, which previously made up 75% of Finland's imported wood, have been cut off due to sanctions and export bans. This has increased demand for domestic Finnish wood and prompted companies to seek alternative wood sources from countries like Lithuania and Sweden. Rising energy and material costs also threaten to reduce profits for some forest industry producers in the coming years. The document analyzes trends in wood prices, exports, and the substitution of fossil materials with wood to meet growing demand.

Combined Illegal, Unregulated and Unreported (IUU) Vessel List.Christina Parmionova
The best available, up-to-date information on all fishing and related vessels that appear on the illegal, unregulated, and unreported (IUU) fishing vessel lists published by Regional Fisheries Management Organisations (RFMOs) and related organisations. The aim of the site is to improve the effectiveness of the original IUU lists as a tool for a wide variety of stakeholders to better understand and combat illegal fishing and broader fisheries crime.
To date, the following regional organisations maintain or share lists of vessels that have been found to carry out or support IUU fishing within their own or adjacent convention areas and/or species of competence:
Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR)
Commission for the Conservation of Southern Bluefin Tuna (CCSBT)
General Fisheries Commission for the Mediterranean (GFCM)
Inter-American Tropical Tuna Commission (IATTC)
International Commission for the Conservation of Atlantic Tunas (ICCAT)
Indian Ocean Tuna Commission (IOTC)
Northwest Atlantic Fisheries Organisation (NAFO)
North East Atlantic Fisheries Commission (NEAFC)
North Pacific Fisheries Commission (NPFC)
South East Atlantic Fisheries Organisation (SEAFO)
South Pacific Regional Fisheries Management Organisation (SPRFMO)
Southern Indian Ocean Fisheries Agreement (SIOFA)
Western and Central Pacific Fisheries Commission (WCPFC)
The Combined IUU Fishing Vessel List merges all these sources into one list that provides a single reference point to identify whether a vessel is currently IUU listed. Vessels that have been IUU listed in the past and subsequently delisted (for example because of a change in ownership, or because the vessel is no longer in service) are also retained on the site, so that the site contains a full historic record of IUU listed fishing vessels.
Unlike the IUU lists published on individual RFMO websites, which may update vessel details infrequently or not at all, the Combined IUU Fishing Vessel List is kept up to date with the best available information regarding changes to vessel identity, flag state, ownership, location, and operations.

This report explores the significance of border towns and spaces for strengthening responses to young people on the move. In particular it explores the linkages of young people to local service centres with the aim of further developing service, protection, and support strategies for migrant children in border areas across the region. The report is based on a small-scale fieldwork study in the border towns of Chipata and Katete in Zambia conducted in July 2023. Border towns and spaces provide a rich source of information about issues related to the informal or irregular movement of young people across borders, including smuggling and trafficking. They can help build a picture of the nature and scope of the type of movement young migrants undertake and also the forms of protection available to them. Border towns and spaces also provide a lens through which we can better understand the vulnerabilities of young people on the move and, critically, the strategies they use to navigate challenges and access support.
The findings in this report highlight some of the key factors shaping the experiences and vulnerabilities of young people on the move – particularly their proximity to border spaces and how this affects the risks that they face. The report describes strategies that young people on the move employ to remain below the radar of visibility to state and non-state actors due to fear of arrest, detention, and deportation while also trying to keep themselves safe and access support in border towns. These strategies of (in)visibility provide a way to protect themselves yet at the same time also heighten some of the risks young people face as their vulnerabilities are not always recognised by those who could offer support.
In this report we show that the realities and challenges of life and migration in this region and in Zambia need to be better understood for support to be strengthened and tuned to meet the specific needs of young people on the move. This includes understanding the role of state and non-state stakeholders, the impact of laws and policies and, critically, the experiences of the young people themselves. We provide recommendations for immediate action, recommendations for programming to support young people on the move in the two towns that would reduce risk for young people in this area, and recommendations for longer term policy advocacy.
