The process of continuous landfilling in landfill areas, particularly in urban areas, produces pollutants in the form of Leachate as a result of infiltration of rainwater that enters the garbage heap and enters the soil. Leachate can contain several heavy metals, including cadmium (Cd), lead (Pb), copper (Cu), chromium (Cr), and zinc (Zn). The BBIHP Testing Laboratory Makassar collected leachate samples using the random sampling method from three pools representing the inlet, the middle, and the outlet. Samples were analyzed using atomic absorption spectrophotometry (AAS). The concentration of heavy metals in Lindi from the inlet, mid, and outlet pools in the Tamangapa landfill is cadmium (Cd) heavy metal content in the highest outlet pool, namely 0798 mg/l, Lead (Pb) is highest in the pond mid, i.e. 0.1097 mg/l, Chrome metal (Cr)+6 both inlet, mid, and outlet concentrations are the same at 0.012 mg/l, and Copper metal (Lead (Pb) and Cadmium (Cd) are the only two heavy metals that have exceeded the quality standards. In addition, the results of bacterial isolation from leachate samples yielded six isolates with bioremediation potential. © The Authors, published by EDP Sciences.
