Abstract

The study investigated the impact of open dumpsite leachate on groundwater quality by examining the physical and chemical properties of groundwater within the vicinity of Oyigbo in Rivers State, Nigeria. Physical and chemical analysis of groundwater samples from three (3) boreholes which constitutes a major source of water for domestic purpose was carried out to assess the quality in view of the proximity of the wells to open solid waste disposal sites. Results show that the water is weakly acidic with pH level ranging from 5.4-6.23; a very soft groundwater with Total Hardness ranging from 1.5-7 mg and low in Total Dissolve Solids (TDS) from 5-55 mg/l. Results from other chemical parameters tested are Cl? ranging from 50-100 mg/l, SO42- has 0.01-1.54 mg/l, ?O3 ranging from 0.035-0.104 mg/l, Total Suspended Solid (TSS) ranging from 0.1-0.3 mg/l, Chromium with 1.08-4.52 mg/l, Cadmium having 0.01-0.03 mg/l, Lead ranging from 0.1-0.39 mg/l, Iron with 0.95-1.53 mg/l, BOD ranging from 9.8-12.8 mg/l, COD with 153.57-171.37 mg/l and DO ranging from 7.1-10 mg/l. The parameters exceeding the allowable limit of WHO standards include Cadmium, Lead, Iron, Chromium, COD, DO and BOD, all major ions revealed concentration within the acceptable limit of the WHO standard. The impacts of indiscriminate dumping activity on groundwater appeared most clearly as high concentrations of Cadmium, Lead, Iron, Chromium, COD, DO and BOD were detected. The study has revealed that the groundwater quality near dumping sites does not conform to the drinking water quality as per WHO standard. The results confirm the need for determining safe distances between wells and waste disposal sites to abate groundwater pollution.
