Over-exploitation of ground water resource (stage of ground water development - more than 100%) refers to the development of ground water resource which is available below the active recharge zone or zone of fluctuation that is sometimes referred as Static or In

In the present report, an attempt has been made to review the various methods for assessment of ground water recharge, present perspective of ground water resources assessment in the country and to suggest the future strategies for refinements of the
methodology for assessment of ground water resources.

National Water Policy (2002) states that

The recent guidelines for the withdrawal of ground water especially by the industries and infrastructure units focus on a specific part of ground water management viz. ensuring sustainability of ground water both in terms of quantity & quality and on land based management of ground water resource.

The hydrogeological environment in the Nagapattinam district has been subjected to pollution considerably. The eastern part of the district being tail end of the canal system, and due to inferior quality of ground water, the agricultural prosperity in the eastern part attained a set back. The agricultural lands are brought under aquaculture use.

The high rate of population growth and high level of urbanization in NCT, Delhi has resulted in over-development of ground water resources. Thus in about 75% area of NCT, Delhi ground water levels are declining at an alarming rate of 0.20 m per annum.

This manual deals with various aspects of investigation techniques for selection of sites, planning and design of artificial recharge structures, their economic evaluation, monitoring and technical au

This manual deals with various aspects of artificial recharge of ground water including planning of artificial recharge schemes, artificial recharge techniques and design of structures, monitoring of augmented water levels and water quality, economic evaluation of recharge projects and issues related to operation and maintenance of artificial recharge structures. Roof top rainwater harvesting techniques which are particularly suitable for urban areas have also been included and described in detail.

This report presents the dynamic ground water resources of India based on GEC'97 (Ground Water Exploitation Committee)with base year as 2004. It identifies the areas where ground water development is at low key and the areas, where ground water development is alarmingly high. The estimation for the individual state was jointly done by the Ground Water Wing of the State Govt.
