“…The relatively low resistivity values of 15 to 50 Ωm obtained from VES 1 and 2 beneath the dumpsite could be attributed to the effect of leachate from the dumpsite. The low resistivity variation indicates the degree of decomposition of the waste materials and saturated zones of leachate within the subsurface 12 , 16 . This may be a result of the vertically downward migration of leachate into the weathered layer.…”

“…The weathered layer has resistivity values ranging from 28 to 95 Ωm and thickness ranging from 7.0 to 19.0 m. The relatively low resistivity values of 28 to 95 Ωm obtained from VES 7 and 8 beneath the dumpsite could be attributed to migrating leachate from the decomposing wastes in the dumpsite. The fractured basement is characterized by resistivity values ranging from 393 to 567 Ωm with layer thickness ranging from 23.0 to 33.0 m. This layer may be indicative of the accumulation zone of leachate 16 which poses a risk to groundwater quality. The fresh basement is characterized by a resistivity value of 776 Ωm and has an undulating basement relief.…”

“…A fractured and fresh basement characterizes the third layer, with layer thickness ranging from 24.7 to 29.6 m. The resistivity values of the third layer ranged from 578 to 1214 Ωm with a mean of 896 Ωm. The mean resistivity simply implies an uncontaminated zone because of the low porosity from the weathered layer 16 . VES 10 extended to the fresh basement with a resistivity of 1214 Ωm.…”

The physicochemical properties of groundwater, geochemical characteristics and subsurface formation of the Oke-Tage waste dumpsite soil material were assessed to determine the impact of the leachate generated from the waste dumpsite on the quality of the groundwater within the study area. Water samples collected from hand-dug wells were analyzed to determine groundwater quality, while soil samples were examined for their geochemical characteristics. Ten Vertical Electrical Sounding (VES) surveys were carried out with an electrode spacing (AB/2) increasing from 1 to 200 m. Also, four 2D electrical resistivity profilings were done using the dipole–dipole configuration. The hydro-chemical analysis showed an elevated Cadmium (Cd) and Lead (Pb) concentration above the maximum permissible limits. The physicochemical results indicated that the Electrical Conductivity (EC) ranged from 1900 to 3670 µS/m, while Total Dissolved Solid (TDS) ranged from 585 to 620 mg/L. The health risk assessment showed no significant health risks associated with exposure to the metals due to HI values less than 1. Based on the VES result, four geoelectric layers comprising topsoil, weathered layer, fractured basement, and fresh basement were identified. The 2D resistivity structures revealed that the topsoil and weathered layers practically merged and are characterized by relatively low resistivity (< 30 Ωm) beneath the dump site. The study concluded that the groundwater and soil in the vicinity of the investigated Oke-Tage waste dumpsite had been negatively impacted to levels that called for caution especially using the water for regular potability purposes.

“…Groundwater has become the safest and most abundant source of potable water in comparison to surface water as it is often shielded from direct human activities. However, pollution of groundwater resources can occur directly from municipal wastewater, industrial discharges, agricultural waste, urban runoff, landfills, or waste dumps and indirectly from air pollution (Adebayo et al, 2015). Many studies have reported the results of interventions to reduce illness through improvements in drinking water, sanitation facilities, and hygiene practices in less developed countries.…”

Water is an essential component for humans, mainly used as drinking water. There are still many people in Indonesia who use springs as a source of drinking water, one of which is in Joben, Pesanggrahan Village, Montong Gading District, East Lombok Regency. Drinking water from springs can be polluted by contaminants such as bacteria, viruses and others during storage and distribution. This study aims to analyze the quality and microbiological feasibility of drinking water sourced from Joben Springs, Montong Gading, East Lombok. The research was carried out in May-June 2021. The research method used was purposive sampling with sampling carried out at three points: the spring, the main reservoir, and the residents' reservoir. The Coliform test was carried out using the Most Probable Number (MPN) method and Escherichia coli (E. coli) identification using Kirby Bauer. The results of this study indicate that the coliform MPN test from the spring sample obtained the highest value in the paddy field, spring, and house sample of 4,050/100 ml and was classified as class E clean water. Moreover, it was very poor water; the lowest was in mountain storage water of 390/100 ml, which was classified as water clean class C bad category. Water from the Joben spring is not suitable for direct consumption by the community, so it needs to be boiled first to kill bacteria and minimize health problems. All samples, there were no coliform bacteria of the E. coli group. The bacteria in all samples were bacteria from other coliform groups. Therefore, further analysis is needed to determine the content of other bacteria in the water at the Joben spring, Pesanggrahan Montong Gading, East Lombok.

“…The waste dump materials generated at this non-engineer, improperly designed and unconstructed landfills and/or open dumpsites biodegrade and generate effluent over some period of time. When the leachate comes in contact with the groundwater table after migrating from the unsaturated zone, it forms a plume that spreads in the flow direction and ultimately contaminates the groundwater of the area (Adebayo et al 2015). The leachate plume may consist of a large amount of organic content, inorganic salts and heavy metals that may pose a serious risk to the environment and public health (Chabukdhara et al 2017).…”

Groundwater quality and its potential health risk around a municipal dumpsite in Ikire, Southwest Nigeria was investigated using ten groundwater samples which were analyzed for physicochemical parameters. The methods used were groundwater sampling, analyses, spatial distribution of heavy metal (Cd, Cr, Cu, Fe, Mn, Pb, and Zn) and quantitative health risk analysis using USEPA equations. The chronic daily intake (CDI), hazard quotient (HQ), and hazard index (HI) were used to examine potential human health risks of heavy metal pollution. The mean concentration values of Cl − , Ca 2+ , K + Mg 2+ , Fe, Cd, Pb and Mn were higher than their respective permissible limits, while the mean concentration values HCO 3 − , Cu and Zn were within their respective limits. The HQ values of the heavy metals via oral ingestion for the children and adults are found in the order: Cd > Pb > Mn > Fe > Zn > Cu and Cd > Pb > Mn > Zn > Cu > Fe, respectively. The HI values via ingestion pathway for all heavy metals were beyond the threshold value of 1.0, indicating high contamination adverse health risk due to an undesirable level of heavy metals. Cadmium is a major contributor to non-cancer effects in children and adults in the groundwater samples in the region. The groundwater is unsafe for drinking and should be treated before domestic consumption.
