A study of seasonal physico-chemical parameters in river Ghaggar was carried out for pre-monsoon and post-monsoon in May 2015 and October 2015. The water quality was studied at 16 sites at upstream and downstream among the towns traversed by the river. Physico-chemical parameters of the samples were measured; moreover, possible sources of contamination were analyzed. Total 40 parameters were analyzed including colour, temperature, turbidity, pH, electrical conductivity (EC), total dissolved solids (TDS), total suspended solids (TSS), sulphate, total hardness, dissolve oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), iron (Fe), mercury (Hg), lead (Pb), copper (Cu), zinc (Zn), total nitrogen, total phosphorus, pesticides and MPN, etc. The findings showed that pH was alkaline in nature, turbidity and total dissolved solids were found above the WHO permissible limits and iron dominated in heavy metals. All the sites were infected by coliform. This study provides critical information for river conservation and its protection by suggesting possible treatment of domestic wastewater before letting in the river.
