The present study aims to assess the spatial and temporal variations of the hydro chemical characteristics of North Zone of GHMC ground water. 80% of the study area occupy with dense residential area. The depth to water level in the area majorly in between 5 to 20m. The hydro chemical data used in the study is collected from bore well and dug wells in December 2022 by the authors. total of 72 sample collected from various location to cover the study area. pH, TDS, Hardness, Alkalinity, Chloride, Sulphate, Sodium And Potassium, Nitrate and flouride were analysed in BVRIT environmental engineering laboratory, Hyderabad. from the result it is observed that the ground water is quality is poor and not suitable for drinking. the contamination of groundwater is due to the lack of maintenance of waste disposal in the study area.
