ENVIRONMENTAL ASPECTS OF GROUNDWATER RESOURCES DETERIORATION IN THE CITY OF THE TAJ
The problem of groundwater deterioration in the environmental regime of the city of the Taj (Agra, latitudes 27º10’ N and longitudes 78º 5’ E), India situated at the river bank of the Yamuna, has been discussed. The present study is based on the physico-chemical analysis of 486 groundwater samples from the residential, commercial, industrial areas; Yamuna banks and dumping areas of Agra city. The analysis of 486 groundwater samples reveals that groundwater of Agra city is contaminated with inorganic species like Ca2+, Mg2+, Cl-, F- and NO3-; metallic species like Fe2+, Pb2+, Cd2+, Zn2+, Hg2+, Cu2+ & Cr6+; organic species like polyaromatic hydrocarbons. In the most of the areas the deterioration of groundwater exceeds with the limit set by the national and international agencies. The possible causes for the deterioration of groundwater resources have been assigned to over exploitation of groundwater and mobilization of contaminants by leaching of continental rocks as well as contaminated soil through dumping sites and wastewater drains etc. It has been concluded that the groundwater of the Agra city is not fit for drinking.
