Groundwater is one of the most important
natural resources. Groundwater has become a necessary resource over the past
decades due to the increase in its usage for drinking, water supply, irrigation
and industrial uses etc. Groundwater resources are now facing threats due to
anthroprogenic activities. Mapping of spatial variability of groundwater
quality is of vital importance and it is particularly significant where
groundwater is the primary source of potable water. The present study has been
undertaken to analyze the spatial variability of groundwater quality for
Chinnar sub basin, Perambalur and Ariyalur District, Tamilnadu state. The study area was selected based on the Hydro geological properties. A
Study on Physico-Chemical parameters of water quality in the salinity affected
areas of Nagapattinam District is taken up to evaluate its suitability for
drinking and irrigation purposes. Ground water samples are to be collected from
the study area from Veppanthattai Taluk to Sannacinallur in Ariyalur district. The
water samples collected at 65 villages and analyzed for pH, Sodium, Total
Hardness, TDS, Chloride, magnesium, Calcium, Sulphates, Bicarbonates,
potassium, Dissolved Oxygen. Geographic Information System (GIS) is used for
spatial and temporal mapping of water quality in the study area. Geographical Information System (GIS) is used for the spatial analysis and
it is a powerful tool for the representation and analysis of spatial information
related to water resources.
