SEASONAL VARIATION OF DRINKING WATER SOURCES AND CONTOUR MAPS - IN THE UPLAND AREA OF THE WEST GODAVARI DISTRICT, AP, INDIAC.A. JYOTHIRMAYEE, SR SHOWRILU, K. SREELATHA AND A. NIRMALA JYOTHSNAAbstract Water plays an essential role in human life. WHO reports that approximately 36% of urban and 65% of rural Indian were without access to safe drinking water. It must be noted that a regular chemical analysis must be done to ensure that the quality of water in this area is not contaminated. Ground Water quality plays an important role in groundwater protection and quality conservation; hence it is very much important to assess the groundwater quality not only for its present use but also a potential source of water for future consumption. Ground water is highly valuable source of water because of its unique properties which may not be possessed by surface water. The chemical quality tests may be difficult to interpret the groundwater quality for the whole region. Therefore, the quality tests results of groundwater can be represented by a variety of graphic techniques developed to display and detect the major chemical constituents. The contour maps are also useful to show the isograms of equally chemical, biological contaminants concentrations with physical parameters. Contour maps are extremely useful for various research areas. This technique could give a more regular gradient of the groundwater table than other methods. This research studies the distribution of chemical contaminants and their concentrations in groundwater of using contour maps interpretation with some chemical analyses and graphic techniques. |
