RECAPITULATION DATA RESULTS OF TEST RIVER AND RESERVOIR IN JAKARTA FOR MARCH 2018

1 All sampling sites (13 locations) did not meet the required quality standards, with unqualified predominant parameters were Total Coliform and Koli Fecal Bacteria and Organic Chemical and COD chemical parameters. This is one indication of domestic waste pollution.
2 For water of STB Cawang and Sunter Reservoir in addition to the above parameters, Turbidity parameters are also included that exceeds the quality standard, while other parameters that also exceed the quality standard are Manganese parameter (Setu Babakan) and Sulfate parameter (STB Shypon Bekasi).
 
3 When compared to the quality data of February 2018 in March 2018 water quality in 13 (thirteen) locations was relatively improved, where in March 2018 there were 3 data of turbidity parameters that exceeded the quality standard of 3 sampling locations ie Curug, Shypon Bekasi and PAB Cawang (West Tarum Canal), while in February there were 7 Turbidity parameter data that exceeded the quality standard from 4 sampling locations.
