The major issue in today world is the ground water pollution and due to increase in the industrialization at the same rate, the ground water pollution is increased. The primary objective this study is to determine the ground water pollution in terms of heavy metals(toxic elements) using Heavy metal pollution Index (HPI) method and Contamination Index (CI) method is used to calculate degree of contamination and this study is carried to know the groundwater is suitable for domestic purposes. An Atomic Absorption Spectrometer (AAS) was used to calculate the quantity of seven heavy metals are present in the ground water and these are Arsenic, Cadmium, Copper, Iron, Manganese Lead and Zinc. The present study area is near Zahirabad Mandal, Sangareddy District, Telangana state, India. In the study area, total thirty nine (39) groundwater samples were collected and analyzed and the individual heavy metals concentration showed in each spatial distribution maps to find out the anomaly and extent of distribution of heavy metals and also demarcate the pollutant to non-pollutant of the basin and delineate the sources. These data were analyzed and used to generate the Heavy metal Pollution Index (HPI), Heavy metal Evaluation Index (HEI), and Contamination Index (CI). For both Pre- and Post-Monsoon seasons, the areas mean HPI value ranges between 422 and 345, the mean HPI value is greater than the critical pollution index value 100, and the mean value of HEI is between 3.4 and 3.1. The testing of HPI, HEI and CI evaluate a region based contamination levels such as low, medium, and high. Many agencies have unique water quality standards (WHO, 2012) that consider various factors in groundwater quality valuation and pollution management. Several pollution index approaches were used for each region. Over all, the scenario of anomaly evolution of the basin indicates that the basin slightly affected by the anthropogenic and geogenic influence. The major area of the basin is unaffected by the anthropogenic and geogenic influence, expect few locations.
