The byproducts of anaerobic processes at municipal solid waste landfills are leachates and gas emissions. One of the landfills operating in the coastal area of Bali Island is the Suwung landfill. The objectives of this research is to identify the water quality index (WQI) and hydrogen sulfide (H2S) parameters, as well as the health complaints by the local community around the Suwung landfill. A total of 12 samples were taken from wells, and surface and coastal water bodies. The parameters measured in this study are TSS, DO, COD, BOD, and NO3-N. The comparison of the parameters were in accordance with PP No. 82 of 2001 for the second-class water quality standards. Each sample for the TSS and DO parameters meets only eight and five quality standards, respectively. Meanwhile the COD parameters are only met by one sample. For the BOD, all samples did not meet the second-class water quality standards. The WQI analysis showed that seven samples were slightly polluted and two samples were polluted moderately. The average WQI value per water quality is 4.12, which means that the water quality around the landfill is slightly polluted. The H2S parameters mention concentrations at four points do not meet air quality standards. Respondents felt uncomfortable with the odour caused by the H2S. The future implication of this study is to know the indications of public health conditions.
