Rivers are the not just the lifeline of our country, but life itself. We may revere them, even worship them but we continue to pollute, choke, and poison their waters. A river, its catchment area, and its floodplains have evolved over millions of years, and once damaged, may not be easy to reclaim.

The subsurface aquifer systems in Mahanadi delta region in Orissa (India) is largely characterized by two groups of freshwater aquifer systems, both of which are prone to saline water mixing/migration with time and development:

• The south western Mahanadi delta region is represented by unconfined to semi-confined freshwater aquifers underlained by brackish/saline aquifer systems with a diffusion boundary.
• The north eastern parts of Mahanadi delta is represented by deep freshwater confined aquifers overlained by brackish/saline water aquifers with aquitard/ aquiclude boundary.
