“…Water and soil pollution result from the indiscriminate release of metal into water bodies during mining. A higher concentration of Hg was found in the soil taken from various artisanal gold mining sites in Ghana, according to Mantey et al [85]. The findings of their investigation were consistent with those of the current study.…”

“…Additionally, the considerable positive association between mercury and temperature supports the finding that mercury toxicity increases as temperature rises [84,85], leading us to record extraordinarily high mercury levels in water samples. As a result, the discovery of mercury in the surface water suggested that untreated sewers transporting the trash from urban and industrial effluent may have been the cause of the pollution.…”

Industrial and urban development are contributing to an increase in global environmental degradation. Therefore, the release of heavy metals from mining-related operations into surface water is harmful to human health. But as anthropogenic influences on the environment grow, surface water characteristics are also alter, impacting aquatic creatures. In order to analyze the acceptability of the surface water in the gold mining area for drinking and irrigation uses, different quality water assessment methodologies were incorporated in this research. In light of this, the purpose of the current study is to comprehend how the hydrogeochemistry and appropriateness of surface water for drinking and irrigation vary every month. The study employed standardized analytical techniques. According to APHA recommendations, all sampling, conservation, transportation, and analysis were completed (2012). All collected samples were transported to the study lab while being kept in an icebox to prevent the degradation of the organic components. As a result, the study is focused on the contamination level in the surface water for a year. Overall, the study highlights important pollutants impacting surface water quality as it passes through Osun State's gold mining regions. Finally, it has been determined that the following criteria are crucial for the stretch of this research season: DO, Hardness, Turbidity, Chloride, Potassium, Nitrate, Lead, TSS, Cadmium, Chromium, Sulphate, Manganese, Mercury, and Arsenic. Most of the physicochemical variables examined in this study fell within their corresponding standard limits. Based on the results of this study, the appropriate constituted authority is encouraged to continuously monitor and assess surface water quality suitability for drinking, domestic, and irrigation purposes by keeping track of the effects of water contaminants and detecting any changes in the water quality. To safeguard and maintain groundwater quality and public health, it is advised that appropriate regulatory policies and water treatment procedures be employed in the area. Additionally, it is proposed that when enhancing water quality and investigating the sustainable use of water resources, surface water pollution should be taken into consideration.

“…Hence, mining communities are in constant need of potable water and rely on groundwater resources for their water needs [4]. However, danger looms as several studies conducted on groundwater quality in gold mining communities in Ghana have reported substantial levels of arsenic often exceeding the 10 µg/L permitted by the WHO [5] [6]. Arsenic in drinking water has been reported to cause human diverse health problems, including cancer, skin thickening and discolouration, high blood pressure, heart diseases, nerve effects like numbness and pain, interference with important cell functions, gastrointestinal disorders, diarrhea, stomatitis, tremor, hemoglobinuria, ataxia, paralysis, depression, pneumonia, among others [5] [7] [8].…”

This study investigated Bacillus subtilis ATCC13952 as an adsorbent for arsenic in groundwater. Batch experiments were used to determine the effect of contact time, adsorbent dose, arsenic (III) concentration, pH, and temperature on the process. The percentage of arsenic (III) removed was high at a contact time of four days, 3.0 mL of Bacillus subtilis ATCC13952, pH 8 and temperature of 35˚C. The kinetics of the process showed the Elovich kinetics model as the best fit for the process. This indicates that arsenic removal was by chemisorption. The analysis of the nonlinear equilibrium isotherms and the error functions showed the Langmuir isotherm as best fit for the process. Mechanistic study of the process indicated bulk diffusion to be the ratedetermining step. Thermodynamically, the process was favourable, spontaneous and feasible. When the community water samples were treated with the Bacillus subtilis ATCC13952 at the optimum contact time, adsorbent dose, pH and temperature, 99.96% -99.97% of arsenic was removed across all sampling points within the studied communities. Hence, the results show that How to cite this paper:

The study was conducted to evaluate the effectiveness of the blend of enzymes, organic catalysts, and probiotics on the water quality of Pasig River and to determine its sustainability to aquatic life. The effects of varying the dosage of the mixture were also identified. The data observed were compared to the standard for fishery water set by the Department of Environment and Natural Resources (DENR). On-site application results were analyzed using paired t-test. All parameters were normally distributed. Temperature, phosphate, and BOD measures were significantly changed at (p<0.05). Results showed mixture effectiveness on temperature, pH, Chloride, Nitrate, TSS, Oil and Grease, and Surfactant as they passed the DAO 2016-08 Class C Standard. BOD, Phosphate, TSS, and Ammonia concentrations were reduced in Ayala samples. DO, Nitrate and Fecal Coliforms concentrations were reduced in Nagtahan samples. Varying the amount of mixture application yields no significant effect on the water quality. Fishes and aquatic life can still not thrive on this kind of water.
