Groundwater samples were collected from different places in Prakasam District for their physico-chemical studies. Laboratory tests were performed for analysis of samples for pH, chlorides, hardness, total dissolved solids and nitrates. Besides models, several water quality indices have been developed and used time to time. Water quality Indices are generally used as a tool to convert a large data set into a much reduced and informative form. Water Quality Index (WQI) by weigted arithmetic Index method is used in the present study to assess the suitability for drinking. It was found that most of the stations have WQI value in the range of 25-49 and concluded as good for drinking. But three stations namely Ongole, Kandukur and Kanigiri have WQI values more than maximum value of hundred and not fit for even domestic use. The higher value of these parameters may have health implications and therefore need attention.

Abstract


Groundwater samples were collected from different places in Prakasam District for their physico-chemical studies. Laboratory tests were performed for analysis of samples for pH, chlorides, hardness, total dissolved solids and nitrates. Besides models, several water quality indices have been developed and used time to time. Water quality Indices are generally used as a tool to convert a large data set into a much reduced and informative form. Water Quality Index (WQI) by weigted arithmetic Index method is used in the present study to assess the suitability for drinking. It was found that most of the stations have WQI value in the range of 25-49 and concluded as good for drinking. But three stations namely Ongole, Kandukur and Kanigiri have WQI values more than maximum value of hundred and not fit for even domestic use. The higher value of these parameters may have health implications and therefore need attention.
