Assessment of Dug Well Water Quality in the Vicinity of the Karya Jaya Landfill, Palembang

Abstract

Dug wells are a primary water source in Indonesia due to affordability and accessibility. However, proximity to landfills raises contamination concerns. This study assessed dug well water quality near the Karya Jaya Landfill, Palembang, integrating physical, chemical, and biological analyses with community perceptions. A qualitative approach was used, involving in-depth interviews with eight key informants and laboratory testing of water samples. Results showed that odor and temperature met regulatory standards, but color, turbidity, and total dissolved solids (TDS) exceeded permissible limits. Chemical analysis indicated low pH and high iron (Fe) concentrations, suggesting contamination from landfill leachate. Biological tests confirmed excessive total coliform and fecal coliform levels, posing potential health risks. Community awareness of water contamination was limited. While some residents recognized clean water criteria, many were unaware of specific contaminants and health effects. Dug well water was primarily used for daily activities, but residents relied on bottled water for drinking. Minor health complaints such as skin irritation were reported, though no direct health impacts were formally documented. These findings highlight the need for improved water management. Strengthening landfill leachate containment, expanding municipal water access, and implementing regular groundwater monitoring are essential. Public health education is crucial to enhance awareness of waterborne disease risks and promote safe water practices.
