- Abstract
Water Quality Index-WQI is useful to transfer complex information of the groundwater quality data into comprehensible and useable data. In this research work, the investigation is carried out by collecting 66 groundwater samples and amalgamating nine water quality parameters for evaluation of groundwater utilizing WQI in pre- as well as post-monsoon of a year in the villages of Gara Mandal of Srikakulam District in Andhra Pradesh. The results confirmed that most of the groundwater sample locations (54.5% of groundwater samples) showed poor quality in both pre- as well as post-monsoon seasons. On the other hand, the correlation matrix indicates the strong positive correlation exists between the chemical parameters like calcium ion and magnesium ion with chloride, sulphate as well as nitrate ion represents that groundwater in the sampling locations has been polluted due to geological conditions, seepage of sewage and anthropogenic activities. Hence a proper treatment is required before utilized for drinking.
