The hydrogeochemical parameters for groundwater of west Delhi were studied to
evaluate the major ion chemistry and solute acquisition processes controlling
water composition, scaling potential and permeability of groundwater. Ninety
three groundwater samples were collected randomly from dug wells and hand
pumps in west Delhi and analyzed for various chemical parameters. The
concentrations of major cations and anions were in the order of Na > Mg > Ca >
K and Cl > SO > HCO > NO , respectively. The main hydrochemical facets of

water were Na-K-Cl-SO and Ca-Mg-SO -Cl types. The electrical conductivity
(EC) represents a clear sign of groundwater contamination from drain water and
44
salts of unused agrochemicals. The Gibbs diagram indicates that evaporation is the
dominant mechanism that control groundwater ion chemistry. Chloride
distribution in the study area showed that, groundwater with chloride
-1
concentration of < 30 meq L is originated naturally, but the origin of higher
concentration is anthropogenic in nature. 86% of the samples have scale forming
ability and only 14% are showing corrosive tendency. The encrustation tendency
is due to CaCO precipitation and hence need for treatment of water to prevent
3


scaling. In general, the permeability index indicate good to permissible use of
water for irrigation, and only a few locations demand remedial measures for better
crop yields. USSL and Wilcox diagram showed that nearly 60% of the
groundwater samples are not suitable for irrigation. Thus, this kind of
investigation can create suitable management plans to protect aquifer as well as
remedial measures for contaminated groundwater by natural and manmade
activities.
