Name of Study Major Findings

Specific Yield Study for Planning and Designing AR Structures in Sub-urban in Chennai

The artificial recharge structure suitable for the region is the percolation pond with injection wells. Injection wells can be constructed inside the tanks to a depth of 13 to 20 mbgl. The top of the injection well should be kept at the flood point level of the tanks.

Study of Ground Water Dynamics and Installation of Real Time Ground Water Monitoring System in NCT, Delhi

Under the study it was proposed to install automatic Data Logger on Piezometer at selected locations. But the procurement of data logger could not be materialized due to certain reasons beyond control. However, the study has been completed using manual measurement

Pilot Project on Aquifer MappingPilot Project on Aquifer Mapping was taken up under Purpose Driven Study component in six different Hydrogeological terrains of the country.

Pilot Project on Aquifer Mapping – Progress• Collection and Compilation of existing data completed.• Various thematic layers prepared.• Identification of data gap completed.• Additional data generated using hydrogeological and geophysical

techniques to fill the data gap. Water Level Data Water Quality Data Ground Water Exploration data through drilling Determination of Aquifer parameters through Pumping test Generation of Geophysical Data using Ground and Heliborne

survey through NGRI as consultant• The integration of geophysical & hydrogeological data is under

progress.• On the basis of hydrogeological data, conceptualization of aquifer

system has been made for all pilot areas. Modeling through simulation is under progress.

Pilot Project on Aquifer Mapping – Preliminary Findings• 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.

Lessons Learnt

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

Post project plan for continuation of HP2 activities

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

Dissemination data and application of HIS

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.

Dissemination data and application of HIS

Data Dissemination:

Data disseminated to various Central and State government

departments, Central & state universities and research students for

different academics and scientific investigations.
