Lead Exposure in Community Well water of Open Dumping Solid Waste Cipayung Indonesia

Background: Lead is a heavy metal toxic can causes environmental contamination and health problems. It is accumulative and can affect to several body systems. Lead can be sourced from nature and human activities. It is can remain attached to soil particles or sediments in water for a years. The movement of lead from soil particles into groundwater may occur if it is exposed to acid rain. One source of lead exposure is the activity at solid waste treatment (TPA: Tempat Pemrosesan Akhir Sampah), which is to be sourced from waste processing leachates which still use the open dumping system. Leachate can infiltrate into shallow groundwater (well) consumed by nearby residents and potentially pollute the shallow groundwater.
Material and Method: This research aims to calculate the risk (RQ and ECR) of lead exposure in well water consumed by residents living around to Cipayung landfill, uses the EHRA (Environmental Health Risk Assessment) method with a cross-sectional study design. The Respondents was 104 people with a total environmental sample of 49 wells.
Findings: The results of risk quotient (RQ) on 104 respondents is RQ real time ≤ 1, RQ lifespan for 40 years indicates RQ>1 and ECR (Excess Cancer Risk) value for 50 years show smaller than 10-4.
Conclusion: Well water nearby the Cipayung landfill is still safe from lead exposure for the risk of non-carcinogenic health problems. However, in the 40 years later there will be risks if the population continues to consume the well water nearby the Cipayung landfill. While the carcinogenic risk for the 50 years later is still within safe limits
