Acute shortage of water supply for domestic and irrigation purposes in hard rock area is accentuated by occurrence of groundwater in limited quantity within sparsely distributed aquifers characterised with secondary porosity of finite areal extent. Tawarja river basin is in drought prone Latur district of India falling in basaltic Deccan Volcanic Province (DVP). which occupies half a million square km area.
Data from 11 000 public supply wells in 87 study areas were used to assess the quality of nearly all of the groundwater used for public supply in California. Two metrics were developed for quantifying groundwater quality: area with high concentrations (km2 or proportion) and equivalent-population relying upon groundwater with high concentrations (number of people or proportion).
Multivariate statistical techniques, cluster and principal component analysis were applied to the data on groundwater quality of Suri I and II Blocks of Birbhum District, West Bengal, India, to extract principal factors corresponding to the different sources of variation in the hydrochemistry as well as the main controls on the hydrochemistry.
