Small scale mining system carried out by local residents in Bunikasih, Sukaluyu Village, Pangalengan District, Bandung Regency causes environmental pollution and long-term ecosystem damage. This is because the mining method does not follow the rules set by the government. To find out the amount of pollution that has occurred, this study was conducted. The research methodology used starts from taking field data samples, then analyzes the chemistry for clean water and waste chemicals. From this study it was found that the presence of heavy metal mercury (Hg) due to mining activities and processing of gold ore using amalgamation with values in the upper reaches of Ciwiwi River = 0.085 mg / kg, in the area of amalgamation gold ore processing = 0.11 mg / kg, and in the lower reaches of Ciwiwi River = 0.097 mg / kg.
