Water Quality of Fresh Water Pond Ecosystem under Sub-Temperate Conditions of Palampur, Himachal Pradesh

The present investigation was carried out for a period to study the pollution status of the fresh water pond ecosystem under subtemperate conditions of Palampur. The surface water samples were collected from the pond at the monthly interval from April, 2014 to March, 2015 and analyzed for different physico-chemical characteristics.. The higher concentrations of free CO₂, chlorides, nitrate-nitrogen, phosphate-phosphorus and low values of secchi transparency and dissolved oxygen throughout the study period indicated the deteriorated water quality of pond ecosystem.
