Groundwater

Organizer: Advanced Centre for Water Resources Development and Management (ACWADAM)

Venue: Pune

Topics:

• Introduction to basics of geology
• Physical geology and geomorphology

Groundwater is a natural replenishable resource. It is an important source for various purposes, including drinking, irrigation and industrial, due to insufficient surface water supply and frequent failure of monsoon. Identification of groundwater zones depends upon many factors such as distribution of rainfall, runoff, grain size of soil, topographic features, type of landform, drainage conditions, lithological characteristics, land use practices, depth to groundwater level and environmental constraints, which are not uniform in any area.

Central Ground Water Board (CGWB) intends to create a directory of ground water professionals and invites bio data of experienced ground water professional (Individuals/Institutions/Scientists/Engineers/NGOs/VOs etc.) working in the field related to ground water/ rain water harvesting/ water conservation/ ground water recharge/ ground water quality/ water well drilling & construction etc.

 It is an innovative version, and has been appreciated in many seminars and national workshops. It gives a logical treatment of mother earth based on human therapy.

Overview

It is surprising that fluoride was found even in surface water bodies like ponds, because fluoride is generally found in deep aquifers. Fluoride is a naturally occurring mineral in the deeper layers of rock beneath the earth's surface, so it was unusual to find it at such high levels even in surface water sources, leading to the conclusion that intensive agriculture in the area has spread the fluoride to the surface.

How exactly do contaminants spread underground? How much urban stress can an aquifer withstand?

With the need for clean fresh water growing daily, finding answers to those questions is a top priority for researchers at G360, the new Centre for Applied Groundwater Research at the University of Guelph in Ontario, Canada.

Groundwater caters to the demand of ever growing domestic, agricultural and industrial sector of the country and is being indiscriminately exploited by several users. On the other hand, rapid urbanization and land use changes has resulted in reduced natural infiltration or recharge of aquifers.

This has led to various problems related to quantity and quality and issues like the decline in water levels, depletion of groundwater resource and quality deterioration. There is thus an imperative need for augmenting the valuable groundwater resource. Artificial recharge and roof top rainwater harvesting is one such method that can revive this precious resource. Several traditional and scientifically proven artificial recharge and rainwater harvesting techniques have been adopted in different parts of the country. These structures have proven to be viable option for augmenting the groundwater aquifers by making use of surplus surface runoff.

With 49 per cent of the total irrigation from groundwater, the state of Andhra Pradesh accounts for 5.3 per cent of the net groundwater irrigated area in the country.
