RECAPITULATION DATA RESULTS OF QUALITY TEST OF RIVER AND RESERVOIRS IN JAKARTA IN MEI 2018

To find out information on the quality of river water and raw water in Jakarta in Mei 2018, PAM JAYA conducted tests on river water and reservoirs in Jakarta with the following results:

  1. Of the 13 sampling sites there are 12 locations not meeting the required quality standards, with non-compliant predominant parameters are Total Coliform and Koli Tinja Bacteria, DHL physical parameters and turbidity and COD chemical parameters. This is one indication of the existence of domestic waste pollution and the inclusion of the dry season.
  2. For Babakan Setu water other than the above parameters, the pH parameter (acidity degree) is also included that exceeds the quality standard, while other parameters that also exceed the quality standard are DHL parameters (Cengkareng Drain and Sunter Reservoir), Turbidity parameters (DCR-5 and Reservoir Sunter), Chloride parameters (Sunter Reservoir), Manganese parameters (DCR-5, DCR-4, Cengkareng Drain, Marunda and Sunter Reservoir), Fe (DCR-5 and Sunter Reservoir) parameters and Organic Zone (Pejompongan Channel Intake) and Sunter Reservoir). The most abandoned parameter locations are the Sunter Reservoir (9 parameters) taken on May 7, 2018, DHL, Turbidity, pH, Manganese, Iron, Organic Substances, COD, Total Coliform and Koliform Feces.
  3. When compared to April 2018 quality data in May 2018 water quality in 13 (thirteen) locations of water quality decreased, where in May 2018 there were 19 COD parameter data (April 3 data) and 7 Manganese parameter data (month April 1 data) that exceeded the quality standard. There is also 1 Chloride parameter data in the Sunter Reservoir that exceeds the quality standard, indicating the presence of an intrusion from seawater
