Abstract
The disposal of wastewater, whether sourced from domestic (household) or industrial activities, can cause environmental pollution if the waste water quality does not meet the waste quality standard. For example, the population density of Jakarta city causes the distance between houses to be closer together, especially in congested areas, so that the location of septic tanks, cubluk (garbage box), and garbage disposal are close to groundwater sources. Some groundwater sources have been contaminated by coli bacteria, from 636 groundwater samples tested there were 285 samples containing E. coli bacteria. Whereas chemically, 75% of these sources do not meet the standard water quality standards for drinking water. Parameters that exceed the quality standard are nitrate, nitrite, iron, and manganese. The presence of nitrates and nitrites indicates that groundwater has been polluted by organic substances. In terms of river water quality, based on the results of monitoring it is seen that in general the quality is not in accordance with its designation and tends to deteriorate from year to year. Observing environmental conditions that tend to deteriorate, then wastewater management must be carried out properly and thoroughly in addition to increasing supervision of waste disposal from sources of pollution, among others through the clean-up program (Prokasih), water-saving movements, application of waste water discharge permits, increasing drinking water services, and improved sanitation, especially in dense residential areas
