Hydro-Geo chemistry of Pallecheruvu Lake

Abstract

Groundwater samples were collected from the surrounding regions of Pallecheruvu Lake. Pallecheruvu lake is located in the southern part of the Hyderabad city ,between latitudes 17 0 20' N and 17 0 30'N and longitudes 78 0 27'30"E and 78 0 30'E , covering an area of about 16.8 hectares. 15 Groundwater samples from selected bore wells and 4 surface water samples were analysed for important physico-chemical attributes by adopting APHA standard methods. The study aims to understand the distribution of groundwater quality in aforesaid region. The following objectives of the study are to determine groundwater quality parameters such as pH, Chlorides (mg/l), Acidity, Alkalinity, Total dissolved Solids, Electrical Conductivity, Turbidity and to create a database and create various thematic maps and map the spatial distribution of groundwater quality in the study area. Inverse Distance Weighted (IDW) interpolation method was used to create various raster maps which show the spatial distribution. Iso concentration map are prepared by using QGIS software. Iso-concentration maps are very useful for predicting the quality of water and to know the concentrations of different elements at different places.
