• 2D & 3D aquifer disposition have been envisaged on the basis of
Conceptual model. 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.

From the experience of the scheme, following suggestions are made
• Since the HP-I and HP-II was not implemented in few states, there is
a need of upscaling the three major components of HP-II through
strengthening of State Ground Water departments by improving of
institutional and organisational arrangements
1. 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.
