Study of groundwater chemistry and salinization in Rechna Doab using hydrochemical and isotopic tools

Technical Report:

Abstract

Isotopic and chemical characterization of groundwater in Rechna Doab were studied. Samples of water from existing shallow and deep wells, etc. were collected and analyzed for their major ionic and stable isotopic (/sup 2/H, /sup 18/O) contents. The chemical data was used to have a knowledge of various aspects of water chemistry. Different compositional types of water existing in the area were identified. It was observed that groundwater at most of the locations belongs to sodium bicarbonate type. The geochemical evaluation of groundwater was also studied. It is suggested that infiltering water picks up carbon dioxide during percolation through the soil zone. This CO/sub 2/rich water upon interaction with the sediments dissolves more soluble ions. With the increase in salinity soluble remains in solution. Chemical quality of water was evaluated for various uses and found satisfactory in most of the cases. Stable isotopic values in combination with conservative ion (Cl) concentration were used to identify the process of groundwater salinization. Three possible processes, mixing with connate marine water, concentration of salts by evaporation and dissolution of salts from sediments was found to be the operating mechanism under the prevailing conditions.
