Global water demand is rapidly growing due to the world increasing population; obviously, this increasing demand is also reflecting the groundwater. The groundwater we use is come from far, rain dropping from cloud on to the ground and seepages from rivers and oceans, patiently but surely it finds its way into aquifers. Groundwater is drastically affected by anthropogenic activities likewise agricultural applications, wastewater discharges, solid waste dumping, and leachate. Due to ground surface development groundwater is highly affected. Different kinds of synthetic organic compounds are found in groundwater aquifers since many years. The aim of this study to investigate the effects of pesticides (being applied to the crops) on the quality of shallow groundwater. To determine the water quality parameters, fifteen samples were collected from the different locations/villages in the suburbs of Hyderabad city. According to results, the groundwater of most of the samples were found contaminated, this means the physicochemical parameters were exceeding WHO guideline for drinking purpose.
