Ground Water Year Book of Maharashtra and Union Territory of Dadra and Nagar Haveli 2014-15

Central Ground Water Board (CGWB), Central Region has established 1772 ‘Ground Water Monitoring Wells’ (GWMW) in the Maharashtra State and the Union Territory of Dadra and Nagar Haveli. Out of which, 210 wells are either abandoned or not being monitored due to various unavoidable reasons. Thus, there are about 1562 wells being monitored with a density of about one active well per 197 sq km. The Central Region monitors ground water levels all over the Maharashtra State and the Union Territory of Dadra and Nagar Haveli (UT of DNH) in 1562 active GWMWs four times in a hydrological year in order to bring out the spatial and temporal changes in the ground water regime. This continuous monitoring provides a valuable tool to decipher the seasonal and long-term changes in ground water levels and quality and in turn helps in managing the ground water resources in a more scientific and effective manner. The present report incorporates the overall behavior of the ground water regime including the quality aspects in the Maharashtra State, and the UT of DNH vis-à-vis rainfall patterns on the basis of the detailed analyses and scientific interpretation of the field data collected from observation wells during the water year 2014-15.
