Barna Watershed is a catchment of Barna River and its tributaries, lies in the Raisen district of Madhya Pradesh. The total area of Barna Watershed is approximately 1129 Sq. Km. The aim of the study was to analyze the observed ground water quality parameters and to create spatial map for drinking water purpose for Barna Watershed. For the above study ground water Samples were collected from the field and some GWQ data were collected from PHED, M.P and National Rural Development Water Programme (IMIS) website under Ministry of Drinking water & Sanitation. The GWQ layers were generated separately for each element for Both Pre-Monsoon and Post-Monsoon Season, from the well point layers with the help of Inverse Distance weighted Method (IDW) interpolation technique using ArcGIS 9.3 software. Each element wise layer has been categorized into three categories (1) potable water in Desirable limits (2) Potable water in permissible limits (3) Non-potable ground water, as per BIS standard 2012. Integrating layers of pre-monsoon; pre-monsoon Ground Water Quality map has been prepared and integrating layers of post-monsoon; post-monsoon Ground Water Quality map has been prepared. Integrating the pre & post monsoon Ground water quality map, final ground water quality class map has been prepared. The Final Ground Water Quality class map has been divided into 9 classes as the standard given by the NRSC, ISRO; Ground Water Quality, manual of RGNDWM-PH IV. The Final Ground Water Quality Class map of Barna Watershed shows, out of 75.04% Non-Potable area73.12% area is Non- Potable due to excess of Iron and out 65.51% Habitations which is falling in Non-Potable class, 56.89% habitation are severely affected by excess of Iron.

Ground Water Quality

The state of Andhra Pradesh, India falls in water stress<sup>4</sup> area. The primary objective of this study is to examine the spatial distribution of different chemical elements with respect to its contamination level. About 70 % of drinking water needs in rural areas and 40 % drinking water needs in urban areas are met from groundwater resources. In the last decades, rapid population growth coupled with agricultural expansion due to subsidized power to agriculture has significantly increased demand on groundwater resources. Combined to this, the effect of Global warming has put stress on ground water which is resulting in declines in water levels and deterioration of ground water quality. This may be evidenced by the fact that the phreatic aquifer which was in use two decades ago, is existing no more now in some of the parts of the study area and the water is being drawn from deeper aquifers beyond phreatic aquifers. The study has been carried out for which one or more elements are contaminated and to study its spatial distribution.

Ground water quality conformance to the World Health Organisation standards for drinking water was carried out and inferred to the health risks associated with use of such quality of water. Water samples were collected thrice a month, from nine boreholes, over a period of twelve months and analysed for physical, chemical and biological parameters. Chemical parameters were tested using UV-Vis photometry. Physical parameters were measured using HI9829 waterproof portable logging multi-parameter meter and biological parameters were determined using the Minimal Media ONRG-MUG test and the Membrane Filtration Method (MF). Results shows that total hardness and Fe concentration were above limit in 78% and 56% of the sampled boreholes, respectively. pH, EC, Ca, Cl, Fl, Mn, Mg and Turbidity were within the acceptable WHO limits. Of the sampled boreholes, 67% were not conforming to the Escherichia coli loads recommended for drinking water. Parametric correlations showed strong and significant correlations between chlorides and fluorides (r = 0.68; p &lt; 0.05), Nitrates and Sulphates (r = 0.78; p &lt; 0.05). There is need to treat borehole water to eliminate E. coli and reduce nitrates and total hardness. Furthermore, analysis and monitoring systems to determine temporal variability and health risks, respectively, needs to be put in place.

Due to industrialization and over population, surface water resources are out of reach from many people so consumption of ground water is the only choice to overcome the water scarcity. Naturally, ground water is one of the significant and potable water resource but some geographical conditions and anthropogenic activities deteriorate the water quality and make it objectionable for drinking. This study was conducted to evaluate the ground water quality of Karachi, Pakistan. For this, 42 ground water samples were collected from different districts of Karachi and analyzed their physicochemical and microbiological characteristics and compared with both international (WHO) and national (SEQS) drinking water standards. Observations of the study declared that overall contamination (physicochemical and microbial) in the ground water samples of different districts of Karachi was as follow West (21%), South (20%), Central (17%), Malir (16%), Korangi (14%) and East (12%). Physical assessment of the study area declared that pH and turbidity of the ground water samples varies in the range of (6.54-7.9) and (0-1.01 NTU) which exist in the standard prescribed limit. Whereas, detection of chemical contaminants particularly TDS (457-12090 mg/L), hardness (118.8-3645 mg/L) and chloride (190-4918 mg/L) content in most of the samples were also exceed from the prescribed limit. Additionally, arsenic was abundantly present ranging from 3.52-13.63 mg/L in all collected samples of Karachi city while the concentration of cadmium (range: 0.0005-0.5012 mg/L) and lead (range: 0.201-1.817 mg/L) were also high in few samples, from the permissible limit of drinking water. Microbial contamination was also detected in which coliforms were present in the range of 0-150 CFU/100mL, which also unfit the water quality. This deteriorated ground water quality of Karachi can be improved by maintenance of proper sanitary conditions of the communities and implementation of water treatments, otherwise consumption of such water may develop serious health related consequences in the consumers.

Geospatial Modelling

Over period of time, the water usage and management is under stress for various reasons including pollution in both surface and subsurface. The groundwater quality decreases due to the solid waste from urban and industrial nodes, rapid use of insecticides and pesticides in agricultural practices. In this study, ground water quality maps for Rupnagar district of Punjab has been prepared using geospatial interpolation technique through Inverse Distance Weighted (IDW) approach. IDW technique has been used for major ground water quality parameters observed from the field samples like Arsenic, Hardness, pH, Iron, Fluoride, TDS, and Sulphate. To assess the ground water quality of the Rupnagar district, total 280 numbers of samples from various sources of tubewells for both pre and post monsoon have collected. Out of which, 80 to 113 samples found Iron with non potable limits ranging 0.3&ndash;1.1mg/l and 0.3&ndash;1.02mg/l according to BIS standard for both the seasons respectively. Chamkaur Sahib, Rupnagar, Morinda blocks have been found non potable limit of iron in both pre & post-monsoon. 11 to 52 samples in this region have sulphate with permissible limits in both the season ranging 200&ndash;400mg/l and 201&ndash;400mg/l. But arsenic had acceptable limit in both the season. Various parameters-wise ground water quality map is generated using the range values of drinking water quality to know the distribution of different parameters and diversification in the concentration of different elements. These maps are very much needful for human being to expand awareness among the people to maintain the Cleanness of water at their highest quality and purity levels to achieve a healthy life.
