Leachate from sanitary landfill and dumpsites have potential to cause soil groundwater contamination, disrupt ecosystems. However, there is little information about dumpsite leachates geotechnical properties their impacts on surface in Bono region, Ghana. This study assessed leachate, of the soil, quality Sunyani. Six triplicate leachates, eleven three water samples were taken at (up-stream, mid-stream down-stream) urban dumpsite, eight around peri-urban dumpsite. Water stored (<4°C) polyethylene bottle for laboratory analysis. Physicochemical leachate analyzed using standard methods. Heavy metals (Cd, Hg, Pb, Zn, Cr, Fe, Cu, Ni) determined atomic absorption spectroscopy. index (WQI) pollution loads (LPL) investigated, while plasticity (Ip) liquid (Il) Atterberg limit test. The results showed that all heavily polluted with mean concentrations chlorides ranged between (2830±220 63810±340), biochemical oxygen demand (358±36 820±80), ammonium ions (82.8±2.2 267.6±62), cadmium (0.49±0.02 5.32±1.0); (LPI) LPL exceeding disposal standards (LDS>100). WQI 6.51 289, indicating excellent sources. Surface was 0.84 776.75, majority having WQI>100. located 75-155 m away Moderate significant negative association established (WQI-P WQI-H) distance multiple R2=0.4709, p=0.0191 R2= 0.4482, p=0.02425 respectively. Statistically, strong & Ip (p < 0.05). implies when sources increased, values decreased, improved.
