Analysis of the Distribution of Heavy Metals in Well Water

Well water for residents around the TPA is the main source of water for the community because all water needs are met from well water, whether for drinking, cooking, bathing, washing, feeding livestock and other needs. Any change in water quality due to the influence of leachate from the TPA will affect well water users, especially for their health. People in this environment are very at risk of health problems, especially due to soil pollution from leachate from the landfill. This research aims to determine the distribution of lead (Pb), mercury (Hg) and copper (Cu) metal content in community wells around the Batu Bola landfill. This research method is to apply exploratory descriptive method. The results of the measurement of metal content were then analyzed by comparing the measurement result data with quality stones issued by Permenkes No. 492 of 2010 concerning Requirements for Drinking Water Quality and Government Regulation Number 82 of 2001 concerning Management of Water Quality and Control of Water Pollution in Class I. The concentration of Hg in well 1 and well 2 is <0.0004 mg/L. While the threshold set by the government is 0.001 mg/L and 0.002 mg/L. The concentration of lead metal (Pb) in well 1 and well 2 is <0.003 mg/L, while the quality standards set by the government are 0.01 mg/L and 0.03 mg/L. The measurement of the concentration of copper metal (Cu) in well 1 and well 2 is <0.006 mg/L, while the quality standards set are 2 mg/L and 0.02 mg/L. The metal content test results showed that all the wells were still below the established quality standards.
