Injection wells can be constructed inside and Designing AR Structures in the tanks to a depth of 13 to 20 mbgl. The top of Sub-urban in Chennai the injection well should be kept at the flood point level of the tanks. Under the study it was proposed to install Study of Ground Water automatic Data Logger on Piezometer at Dynamics and Installation of selected locations. But the procurement of data Real Time Ground Water logger could not be materialized due to certain Monitoring System in NCT, Delhi reasons beyond control. However, the study has been completed using manual measurement Pilot Project on Aquifer Mapping was taken up under Purpose Driven Study component in six different Hydrogeological terrains of the country.

Different Aquifer systems have been demarcated. Bihar – Three Aquifers delineated and Palaeochannel have been characterized. Maharashtra - The zones of each flow depicting intertrappean, weathered and compact basalt could be identified and Gondwanas & Basalts have been precisely demarcated. Tamil Nadu - Four aquifer systems have been clearly indicated in Pilot area of Tamil Nadu; Palaeochannel showing fresh water aquifer comprising of coarse sand is seen at the depth of 100-110 m running N-S and occurrence of limestone at shallow depth along the coast at places may indicate fault. Karnataka - Potential zones identified at select locations. • The project is under progress and integration of results would bring out the refinement in sub surface disposition of aquifer; the efficacy of different techniques and protocol for use of Geophysical methods.

Introduction of e-GEMS to non-HP states on mutual consent of respective state governments 2. Development of Standard protocol for use of geophysical techniques for aquifer mapping from the results of Pilot Project on Aquifer Mapping, which will be used for National Aquifer Mapping programme. 3. Transfer and dissemination of hydrological and water quality data for basic water resource evaluations between central and all the state agencies Application of HIS: Following reports have been published using HIS data: State Report - Regional Groundwater Scenario depicting the occurrence, development potential and management options for groundwater resources of the state District report - Groundwater Scenario & formulation of sustainable groundwater development Strategy at the district level Ground Water Year Books - Groundwater Year Book for each region & Groundwater Year Book consolidated for the country are published every year Groundwater Estimation Report as in 2004, 2009 & 2011 by each States Assessment of Groundwater resources for each state Water Supply Investigation report - Feasibility report for sustainable groundwater development Groundwater Exploration Report - Summary of exploration carried out by Central Ground Water Board In addition, application of HIS data in Artificial Recharge Scheme formulation and water quality investigations. Data Dissemination: Data disseminated to various Central and State government departments, Central & state universities and research students for different academics and scientific investigations.
