Abstract

The water quality index (WQI) of Goalpara town and its surrounding areas in Assam was studied and evaluation made for suitability of water for drinking purposes. Twenty groundwater samples from tube wells and open wells were collected during the period from November, 2007 to March, 2008 and chemically analyzed. It was found that WQI of tube well is 5.5% excellent, 60% good, 14% poor and 20% very poor for drinking purpose, while for open wells it was 38% good, 31% poor and 31% very poor. Comparatively tube wells water is better than the open wells water. It was found that excessive application of fertilizers, pesticides and irregular uses are mostly responsible for degrading water quality, and to mitigate it proper treatment and measures have to be taken.
