The research was carried out in March 2023-July 2023. Water sampling was carried out at 6 points using the grab sampling method. The parameters analyzed in this study were temperature, pH, Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Nitrate (NO3-N), Phosphate (PO4), Iron (Fe), Lead (Pb) and E. coli. The results of water quality Gunung Putri Pond for parameters COD, Fe, Pb and E. coli exceed the quality standards of Government Regulation No. 22 Year 2021 Class 2. The water quality status of Gunung Putri Pond used Pollutant Index (IP) method with an average value of 2.78, which is lightly polluted category.
