Analysis of Groundwater Quality in Thiruvallur

Abstract

The study was aimed to determine the quality of Groundwater flowing in the Tiruvallur District. Tiruvallur is an administrative district present in the southern state of Tamil Nadu.The district has a mixture of urban and rural characteristics while the southern and northern part of the district has influence of Andhra culture due to its position in the state. In order to determine the quality of groundwater along the entire district,the district is divided into 14 blocks and  water samples were collected nearer the residential dwellings of  these bocks and were tested to determine the Physico-Chemical Characteristics such as pH, Alkalinity, Hardness, Acidity and Chlorides of the district. The results indicated that the Physico-Chemical parameters of all the samples were within the prescribed limits except Minjur and pallipetu which exceeded for Chlorides. Water Quality Index (WQI) is determined considering these parameters which proves the Groundwater flowing in the district is fit for drinking and domestic purposes.
