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.

Abstract

Noise pollution is one of the important pollution problems confronting the modern and fast pacing world. The impact of noise pollution by trains is considered to be of concern in the areas where railway tracks are situated in/near residential areas. With the introduction of fast moving trains the noise pollution has been substantially increased. In the present study, owing to its importance, a noise survey was carried out in the residential areas within the vicinity of railway tracks. The effectiveness in reducing the noise by building materials has also been studied.
