PDAM Bandung is a local company engaged in the treatment and supply of drinking water to communities in Bandung. Source of raw water from surface water are <br /> <br /> <br /> among Upper River Cikapundung with the intake area is Dago Bengkok and Bantar Awi and Upper River Cisangkuy with the intake area is Cikalong. But at this time the <br /> <br /> <br /> water quality of the river from time to time decreases because if the waste of human activity. Even in the upstream areas raw water intake is thought to be contaminated as well. Therefore, this study was conducted to measure the water quality at the <br /> <br /> <br /> intake areas to determine the contamination happened. This research was conducted in the three intakes namely Dago Bengkok, Bantar Awi, and Cikalong by looking at <br /> <br /> <br /> time variations of weekday and weekend, samples were taken three times in one day which are morning, noon, and evening. Parameters measured consist of physical, chemical and biological parameters including pH, DO, temperature, turbidity, BOD, COD, total coliform, E.coli, total microbes, ammonia, nitrate, and total phosphate. After knowing the results of laboratory tests compared with Regulation 82 of 2001 for class I. Among of these parameters for the threes intake those are above the quality standards are BOD, COD, total coliform, ammonia and total phosphate. All three intakes showed values ranging from 40-50 COD mg /L-1 , BOD 6-11 mg / L-1 , total coliform 100.000-500.00 MPN/ 100 ml, ammonia 0.1- 0.7 mg / L-1 and total phosphate from 0.1-0.6 mg/ L-1. If compared within three intakes, intake Dago Bengkok is the intake that shows the most number of parameters exceeding the water quality Standar I. From measurement results above can be said that in general the source of waste flow into Cisangkuy and Cikapundung river is domestic waste, agriculture, and animal husbandary.
