Seasonal Variation of Groundwater Quality in and Around Laharpur Reservoir, Bhopal

Variations in availability of water with respect to time, quantity, and quality are playing a very significant role in the development of economy of a country. For the different uses, one may require different criteria of water quality as well as standard methods for reporting and comparing results of water analysis. Groundwater and other water bodies in the region of central India are getting contaminated due to numerous types of discharge by the human activities, residential, municipal, commercial, industrial, and agricultural activities. Bhopal, the capital of province of the Madhya Pradesh in India, has a number of water bodies. Laharpur reservoir is one of them. An attempt is made to investigate the seasonal variation in groundwater quality in and around the area of the Laharpur reservoir. The study has revealed from the analyzed results of collected groundwater samples that certain parameters, namely EC, TH, TDS, BOD, chlorides, were exceeding the desirable limit throughout the investigation period in all locations. This is due to the leaching of contaminants into the groundwater. Based on the findings, it is suggested to the local government that discharged wastewater from the sewage of residential and local industrial area must be treated properly as per the standard to avoid its adverse impact on the human health of the region.
