Identification Of Ground Water Potential Zones In Tamil Nadu By Remote Sensin...IJERA Editor
A case study was conducted to find out the groundwater potential zones in Salem, Erode and Namakkal districts, Tamil Nadu, India with an aerial extent of 360.60 km2. The thematic maps such as geology, geomorphology, soil hydrological group, land use / land cover and drainage map were prepared for the study area. The Digital Elevation Model (DEM) has been generated from the 10 m interval contour lines (which is derived from SOI, Toposheet 1:25000 scale) and obtained the slope (%) of the study area. The groundwater potential zones were obtained by overlaying all the thematic maps in terms of weighted overlay methods using the spatial analysis tool in Arc GIS 9.3. During weighted overlay analysis, the ranking has been given for each individual parameter of each thematic map and weights were assigned according to the influence such as soil −25%, geomorphology − 25%, land use/land cover −25%, slope − 15%, lineament − 5% and drainage / streams − 5% and find out the potential zones in terms of good, moderate and poor zones with the area of 49.70 km2, 261.61 km2 and 46.04 km2 respectively. The potential zone wise study area was overlaid with village boundary map and the village wise groundwater potential zones with three categories such as good, moderate and poor zones were obtained. This GIS based output result was validated by conducting field survey by randomly selecting wells in different villages using GPS instruments. The coordinates of each well location were obtained by GPS and plotted in the GIS platform and it was clearly shown that the well coordinates were exactly seated with the classified zones.

Water-Body Area Extraction From High Resolution Satellite Images-An Introduct...CSCJournals
Water resources play an important role in region planning, natural disaster, industrial and agricultural production and so on. Surveying of water-bodies and delineate its features properly is very first step for any planning, especially for places like India, where the land-cover is dominated by water-bodies. Recording images, such as from satellite, sometimes does not reflect the distinguished characteristics of water with non-water features, e.g. shadows of super structures. Image of water body is confused easily with the shadow of skyscraper, since calm water surface induces mirror reflection when it gives birth to echo wave. Over the past decade, a significant amount of research been conducted to extract the water body information from multi-resolution satellite image. The objective of this paper is to review methodologies applied for water body extraction using satellite remote sensing. First, studies on water body detection are treated. Methodological issues related to the use of these methods were summarized. Results from empirical studies, applying water-body extraction techniques are collected and discussed. Important issues for future research are also identified and discussed.
Remote sensing uses electromagnetic radiation to acquire geospatial data without direct contact with objects.

Evaluation of Groundwater Resource Potential using GIS and Remote Sensing App...IJERA Editor
Environment and Development are the two wheels of the cart. However, they become antagonists at some
points. It has been witnessed many a times that development is done at the cost of environment. Analysis and
assessment tools like GIS along with Remote Sensing have proved to be very efficient and effective and hence
useful for management of natural resources. Groundwater is a precious resource of limited extent. In order to
ensure a judicious use of groundwater, proper evaluation is required. There is an urgent need of planned and
optimal development of water resources. An appropriate strategy is required to develop water resources with
planning based on conjunctive use of surface and subsurface water resources. Integrated remote sensing and GIS
can provide the appropriate platform for convergent analysis of diverse data sets for decision making in
groundwater management and planning. Sustainable water resources development and management necessarily
depends on proper planning, implementation, operation and maintenance. The interpretation of remote sensing
data in conjunction with conventional data and sufficient ground truth information makes it possible to identify
and outline various ground features such as geological structures, geomorphic features and their hydrologic
characters that may serve as direct or indirect indicators of the presence of ground and surface water. Remotely
sensed data provides unbiased information on geology, geomorphology, structural pattern and recharging
conditions, which logically define the groundwater regime of an area. Groundwater resource potential has been
evaluated in Pulivendula-Sanivaripalli, Kadapa district, Andhra Pradesh, India, using remote sensing and
Geographic information system. Under this study, three thematic maps viz. Geological map (Lithology and
Structure), Geomorphological map and Hydro morphological maps were prepared. These thematic maps have
been integrated with the help of GIS. Appropriate weightage has been assigned to various factors controlling
occurrence of groundwater to assess the groundwater potential in each segment of the study area. The area has
been classified into high potential, moderate potential, low potential and non-potential zones landforms ground
water development on the basis of hydromorphological studies. Some of the favorable locations have been
suggested to impound the excessive run off so as to augment the ground water resources of the area.
Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.

points. It has been witnessed many a times that development is done at the cost of environment. Analysis and
assessment tools like GIS along with Remote Sensing have proved to be very efficient and effective and hence
useful for management of natural resources. Groundwater is a precious resource of limited extent. In order to
ensure a judicious use of groundwater, proper evaluation is required. There is an urgent need of planned and
optimal development of water resources. An appropriate strategy is required to develop water resources with
planning based on conjunctive use of surface and subsurface water resources. Integrated remote sensing and GIS
can provide the appropriate platform for convergent analysis of diverse data sets for decision making in
groundwater management and planning. Sustainable water resources development and management necessarily
depends on proper planning, implementation, operation and maintenance. The interpretation of remote sensing
data in conjunction with conventional data and sufficient ground truth information makes it possible to identify
and outline various ground features such as geological structures, geomorphic features and their hydrologic
characters that may serve as direct or indirect indicators of the presence of ground and surface water. Remotely
sensed data provides unbiased information on geology, geomorphology, structural pattern and recharging
conditions, which logically define the groundwater regime of an area. Groundwater resource potential has been
evaluated in Pulivendula-Sanivaripalli, Kadapa district, Andhra Pradesh, India, using remote sensing and
Geographic information system. Under this study, three thematic maps viz. Geological map (Lithology and
Structure), Geomorphological map and Hydro morphological maps were prepared. These thematic maps have
been integrated with the help of GIS. Appropriate weightage has been assigned to various factors controlling
occurrence of groundwater to assess the groundwater potential in each segment of the study area. The area has
been classified into high potential, moderate potential, low potential and non-potential zones landforms ground
water development on the basis of hydromorphological studies. Some of the favorable locations have been
suggested to impound the excessive run off so as to augment the ground water resources of the area.

Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.

Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

Recycling and Disposal on SWM Raymond Einyu pptxRayLetai1
Increasing urbanization, rural–urban migration, rising standards of living, and rapid development associated with population growth have resulted in increased solid waste generation by industrial, domestic and other activities in Nairobi City. It has been noted in other contexts too that increasing population, changing consumption patterns, economic development, changing income, urbanization and industrialization all contribute to the increased generation of waste.
With the increasing urban population in Kenya, which is estimated to be growing at a rate higher than that of the country’s general population, waste generation and management is already a major challenge. The industrialization and urbanization process in the country, dominated by one major city – Nairobi, which has around four times the population of the next largest urban centre (Mombasa) – has witnessed an exponential increase in the generation of solid waste. It is projected that by 2030, about 50 per cent of the Kenyan population will be urban.
Aim:
A healthy, safe, secure and sustainable solid waste management system fit for a world – class city.
Improve and protect the public health of Nairobi residents and visitors.
Ecological health, diversity and productivity and maximize resource recovery through the participatory approach.
Goals:
Build awareness and capacity for source separation as essential components of sustainable waste management.
Build new environmentally sound infrastructure and systems for safe disposal of residual waste and replacing current dumpsites which should be commissioned.

The status.
Solid waste generation rate is at 2240 tones / day
collection efficiently is at about 50%.
Actors i.e. city authorities, CBO’s , private firms and self-disposal
Current SWM Situation in Nairobi City:
Solid waste generation – collection – dumping
Good Practices:
• Separation – recycling – marketing.
• Open dumpsite dandora dump site through public education on source separation of waste, of which the situation can be reversed.
• Nairobi is one of the C40 cities in this respect , various actors in the solid waste management space have adopted a variety of technologies to reduce short lived climate pollutants including source separation , recycling , marketing of the recycled products.
• Through the network, it should expect to benefit from expertise of the different actors in the network in terms of applicable technologies and practices in reducing the short-lived climate pollutants.
Good practices:
Despite the dismal collection of solid waste in Nairobi city, there are practices and activities of informal actors (CBOs, CBO-SACCOs and yard shop operators) and other formal industrial actors on solid waste collection, recycling and waste reduction.
Practices and activities of these actor groups are viewed as innovations with the potential to change the way solid waste is handled.
CHALLENGES:
• Resource Allocation.
