“…When surface water intermingled with groundwater, the contaminants in the surface water are introduced into the groundwater system, vise a vise (Dehghani et al, 2018;Tóth, 2020;Zhou et al, 2020). Ideally, the recommended value of pH in potable water should not exceed the range of 6.5 -8.5; this implies that groundwater in the study area in terms of pH value is not suitable for drinking purposes because over 50% of the groundwater exceeded the recommended limit (Soveri, 1992;WHO, 2003;WHO, 2017;WHO, 2021;SON, 2015). The EC and TDS results on the other hand show an appreciable level of acceptance for drinking and irrigation purposes but continue dissolution of materials in the groundwater system can cause unusual level of EC and TDS respectively.…”

The aim of this paper was to evaluate the hydrogeochemistry of groundwater suitability for drinking and irrigation purposes in Okerenkoko Gbaramatu Kingdom, South-South Region, Nigeria using standard methods. The results obtained in the study indicates that over 70% of the groundwater under investigation fell in the category of C3S1 and C4S1 in the USSL salinity diagram implying high to very high salinity. The concentration of Lead (Pb) in all the samples collected exceeded the recommended value of 0.01 mg/L set by the World Health Organization and the Standard Organization of Nigeria respectively. Groundwater from the study area can only serve as irrigation purpose for salt tolerant crops like the sweet potato, grain-sorghum, sugar beet, cotton and carrot. The production of these crops on the vast arable fallow land will contribute significantly to food security and economic advancement of the study area and the global community at large. Conversely, the groundwater cannot be consumed unless treatment is administered.

“…Additionally, the acidic wastewater can lead to acidification of groundwater bodies particularly shallow wells which is a major source of water for the residents around the tannery. Acidified groundwater is characterized by a decline in pH and alkalinity and this also stimulates the release of toxic chemicals such as nitrate, aluminium, zinc, cadmium and chromium into the water ( Knutsson, 1994 ; Soveri, 1992 ).…”

Tannery wastewater is one of the most toxic waste generated in industries. In spite of this, there still remains a paucity of information on characteristics of wastewater generated from artisanal tanneries. This study, therefore, assessed the water consumption, wastewater generation rates, physicochemical and microbiological characteristics of wastewater produced from each process unit of an artisanal tannery in Ghana. The study revealed that the total amount of water use in the tannery ranged between 1171 and 2120L/day whilst the total volume of wastewater generated was within 820 and 1324L/day. Physicochemical characteristics of the different wastewater types generated at the tannery including chemical oxygen demand (13600–24333.30 mg/L), biochemical oxygen demand (1445.64–2803 mg/L), ammonia (3.20–21.38 mg/L), colour (950.35–53900.10PtCo), electrical conductivity (8170 - 10080 μS/cm), turbidity (450.24–1805NTU), suspended (1033.50–3216.40 mg/L) and dissolved (26166.50–4996.65 mg/L) solids exceeded the guidelines set by the Ghana Environmental Protection Agency. There were also high levels of chlorides, sodium, sulphates and calcium ions. The most dominant anion and cation in the wastewater were chlorides (715–20490.60 mg/L) and sodium ions (258–14056.45 mg/L) respectively. Heavy metals identified in the wastewater included zinc, aluminium, iron and chromium ions with the most dominant one being aluminium ions (0.58–78.18 mg/L). Whilst the E-coli was below detectable limit, the count of total coliforms ranged between 0 and 4.5 × 10 4 CFU/100mL. Five helminth egg species ( Ascaris lumbricoides, hookworm , Trichuris trichiura , Strongyloides stercoralis, and Enterobius vermicularis ) were identified with their numbers surpassing the safe limit set by the World Health Organisation for irrigation purposes. These results indicated that the indiscriminate discharge of the untreated wastewater on the bare soil as it is practised at the tannery has the potential to adversely affect public and environmental health. Appropriate treatment schemes are therefore, required to treat the wastewater to safe limits prior to discharge.

“…High levels of Al observed could be linked to acid rains. Studies conducted by some researchers(Edmunds and Kinniburgh 1986;Hart et al, 2021;Soveri, 1992) attributed the high Al content of groundwater to the acidi cation of aquifers caused by acid rains.Mean concentrations obtained for Tl, U and V were relatively low and did not exceed recommended values (0.002, 0.03, 0.05 mg/L respectively) set by WHO (2017). Lower levels of these TEs found suggest that they do not constitute a health concern; nevertheless, at higher concentrations, they may be harmful.…”

Human health and socioeconomic sustainable development are inextricably linked to water quality. Trace element (TE) contamination in groundwater is a key factor for health risk assessment and one of the environmental challenges linked with Ghana’s sustainable development. This study aims to investigate TEs concentrations in groundwater used for drinking and domestic purposes and their potential health risk in the Kumasi Metropolis using multivariate statistics. In the study, 23 groundwater samples were analyzed for 32 TEs using Perkin Elmer Nexion 2000 Inductively Coupled Plasma Mass Spectrometer (ICP-MS). The study revealed that the concentration of some trace and toxic elements such as Al, Cu and Pb exceeded their corresponding WHO permissible standards. Hazard index (HI) values and total likely cancer risk (TLCR) values computed for non-carcinogenic and carcinogenic health risk indicate that 91.3% of the total sampling sites presented health concerns to adults and children. The mean TLCR values associated with exposure to carcinogenic metals via ingestion of groundwater samples were estimated to be 2.09 × 10− 4 and 4.44 × 10− 4 for adults and children respectively. Exposure through ingestion pathway was found to be more risky compared to dermal contacts. Children are particularly vulnerable to these health hazards. Pearson correlation (PC) matrix, principal component analysis (PCA) and hierarchical cluster analysis (HCA) suggested that sources of TEs in the groundwater are attributed to both anthropogenic and geogenic factors.
