Ground Water Prospects Mapping

Drinking Water technology mission is one of the five technology missions launched by the then Prime Minister of India (1986). Under this initiative NRSC has developed methodology and prepared Groundwater Prospects Map on 1:50,000 scale for the entire country, which is put to public usage through BUVAN BHUJAL ISRO’s Geoportal.
These maps represents groundwater yield & depth information, possible exploration zones, conservations measures, sustainability in a holistic manner.

Ground water quality mapping is another important activity which is carried out by NRSC by organizing the seasonal quality data of geogenic contaminants, collected from wells by State Departments. The point data are interpolated in GIS environment for visualization in association with ground water prospect map, which differentiates the potable and non-potable groundwater sources.

Salt water intrusions in coastal aquifers and its impact on groundwater system is being studied based on GPR & RS techniques.
Groundwater budgeting, draft estimation & Modelling studies under National Aquifer Mapping & Management (NAQUIM) project has been carried out by coupling of RS inputs with field based observations.
