This is an article about what is some of the things happening to help with the water issue.

Even though Indonesia water resources accounted has for almost six percent of the world water resources or about 21 percent total water resources in the Asia Pacific region, in fact clean water is becoming serious problem in Indonesia.  In the recent, at least 80 percent of 250 million Indonesian has no access to piped water. Due to difficulties and limited access to clean water large number of people still using river for drinking water, bathing, and washing.  The data show that from 51,372,661 houses in Indonesia, there is only 42.8 percent has domestic waste treatment. About 56.15 percent of household disposes their domestic waste directly to river body. The result of water quality monitoring in 30 rivers in Indonesia indicates that most of river water quality do not meet water criteria class 1 (drinking water raw based on Regulation 82/2001). On the basis of parameter BOD, there is only 21 percent of samples meet the water criteria class 1. In other word most of river BOD is above 10 ppm, in fact concentration of BOD could reach 100 ppm. This figure is not different for other parameter such as COD and DO.   For example, water quality in location near mining area potentially contaminated by heavy metal such as mercury (Hg). Monitoring data show that some level of mercury (Hg) concentration has been detected at nine sampling point from 16 sampling point with the highest level of dissolved mercury in one of mining area could reach 2.78 ug/l.
