The Pithampur Industrial sectors I, II, and III, located approximately, 45 km from Indore in Central India have emerged as
one of the largest industrial clusters in the region. Various types of industries ranging from automobiles to chemicals and
pharmaceuticals have been set up in the region since 1990. Most of the industries have effluent treatment plants (ETP) for
treating wastewater before its disposal on land and/or in water body. The present study is an attempt to assess the groundwater
quality in the watersheds surrounding these industrial sectors to develop the baseline groundwater quality in order to enable
the policy makers to facilitate decisions on the development of industries in this region. The industries are located in two
sub-watersheds, namely, Gambhir river sub-watershed and Chambal river sub-watershed. Geologically, the study area is located
in the Deccan traps of Cretaceous to Paleocene age. The different basaltic flow units underlie clayey soils varying in thickness
from 2–3 m. The aquifer is mostly of unconfined nature. Samples have been collected from a network of observation wells set
up in the watersheds. The water quality analysis of the groundwater samples has been carried out six times during three hydrological
cycles of 2004, 2005, and 2006. The results indicate that a few observation wells in the vicinity of the industrial clusters
have very high TDS concentration and exceed the Bureau of Indian Standards (BIS) guideline for TDS concentration. The contamination
of groundwater has been more severe in the Gambhir watershed as compared to the Chambal watershed. The presence of the impermeable
clay layers has resulted in a slow migration of contaminants from the sources. The findings reveal that there is no significant
groundwater contamination in the Pithampur industrial sectors except in the vicinity of the industrial clusters, which indicates
that there is good environmental space available for the expansion of industrial units in the Pithampur industrial hub. 相似文献
