Groundwater quality assessment in parts of Krishna River Basin, Weepangandla and Chinnambhavi Area, Mahabubnagar district Telangana India

Groundwater quality is an important factor for determining its suitability for drinking, agricultural, industrial and domestic purposes. This paper examines the quality of groundwater for irrigation around Weepanagandla area, Mahabubnagar District, Telangana State, adjacent to Krishna River, northern part of Cuddapah Super Group and the north of Eastern Dharwar Super Group in India.

A total of forty-eight samples have been collected in the study area from (a) open wells (dug wells) six-(b) bore wells-twelve and (c) hand pumps-thirty samples. Groundwater quality was evaluated and investigated to ascertain, the quality of water in Weepanagandla area. The groundwater quality assessment has been carried out by evaluating the parameters SAR, %Na and Permeability Index by using calculation of the groundwater geochemical parameters-pH, EC, TDS, TH, Ca, Mg, Na, K, Cl, COƒ, HCOƒ, SO‘ ionic concentration.

Groundwater analytical results were compared with standard guidelines set by Bureau of Indian Standard (BIS, 2003, 2009) and World Health Organization (WHO, 2011) for drinking and irrigational purpose. Satellite images (LISS-IV) were used to classify (Arc GIS) the potential zones with acceptable groundwater quality for drinking and through satellite data using visual interpretation techniques to study possible storage and movement of water, the possible source of pollution of groundwater quality by hydrogeological inferences and agro-chemical decomposition.
