AbstractThe paper aims to determine the most significant physicochemical indicators of the effects that a lined landfill in southern Poland has had on groundwater quality. The results of the tests of groundwater and leachate water from the landfill for the period 2009 to 2016 were subjected to a detailed statistical analysis based on the 10 physicochemical parameters. A factor analysis was conducted considering the European Union and national requirements for landfills using analytical and statistical tools. The leachate contamination indicators from a landfill were analysed to reveal their interaction with the groundwater. The assessment indicated that there was an elevated and statistically significantly higher electrical conductivity and copper and total organic carbon concentrations in groundwater hydraulically downgradient of the landfill. The assessment also indicated that there were significant differences in the correlations between chemical parameters downgradient of the landfill and that there was a trend of increasing concentrations of some chemical constituents in groundwater. The adverse effects of the landfill were due to the deposited amount of waste exceeding 10 Mg per day. The impact was noticeable despite low and decreasing concentrations of heavy metals (Hg, Cu, Cd, Pb and Zn) in the leachate. The deterioration of the chemical state of the groundwater in the landfill vicinity could result in the extended time of pollutant migration or mass transport in the irrigated soil medium due to the limited efficiency of the leachate intake system or sealing screen after more than 20 years of landfill operation.

The Impact

Waste disposal and management is a challenge in developing countries and has great influence on the groundwater quality. This research aimed at assessing the impact of leachate on nearby wells within the vicinity of active dumpsite in Yaba, Lagos, Nigeria. Four vertical electrical sounding and four electrical resistivity tomography using Schlumberger and Wenner electrode configurations respectively were carried out at the dumpsite. Physicochemical analysis of water samples from neighbouring wells were also conducted. The geo-electric curve showed four different subsurface layers. The electrical resistivity surveys revealed low resistivity values of s uspected leachate between 1.77 and 39.1 Ωm at a maximum depth of 20.8 m from the subsurface. The leachate polluted area is characterized by low resistivity values ranging from 1 to 10 Ωm, the thickness ranged from 0.5 to 9.2 m and the dir ection of leachate flow is from the northeast to southwest of the canal. The physicochemical analysis revealed that SO42- (70 - 89 mg/l) and Cl- (115.7 - 190.5 mg/l) have values within the World Health Organization (WHO) permissible limit. The pH (5.08 - 6.07), Electrical conductivity (774-1028 μS /cm) and the total dissolved solids values fall below WHO limit. The impact assessment of dumpsite effect revealed that the groundwater quality was affected by the leachate flow.
