Drinking water quality of PAM in Jakarta, Bogor, Tangerang and Bekasi between the year of 1999 -- 2001 has been studied. Water quality was determined by a series of physical and chemical test at Chemical Laboratory Pusat Penelitian dan Pengembangan Farmasi dan Obat Tradisional as stated in Permenkes no.416/Menkes/Per/JX/1990 on condition and water quality control including smell, color, turbidity, contents of manganese, iron, nitrite, sulphate, organic subtance, turbidity, hardness and pH.
Total sampling was done on all drinking water samples from DKI Jakarta, Bogor, Tangerang and Bekasi delivered to be tested at Pusat Penelitian dan Pengembangan Farmasi dan Obat
Tradisional between 1999-2001 and destilled water as control.
Result of the study from 431 drinking water samples shows that samples that met the requirements as drinking water is 91,65% and 8,35% sub standard, most of the the sub standard
drinking water is cause by the contents of manganese (4,41%), iron (2,09%), organic subtance (1,62%), chloride (0,93%) and high water hardness (0,23%) as well as pH (3,15%), turbidity (1,86%) and colors (1,62%). Statistically, the water quality of PAM in Jakarta, Bogor, Tangerang and Bekasi at 1999, 2000 and 2001 is not different.
