The aim of this study is to evaluate the potential impacts of 8.5 MW thermal power plant on soil and water quality within its location, Lekki area, Lagos State. The study area was geo-referenced using the existing map and Geographical Positioning System. Auger was used to sample soil at three different locations within the power plant. The soil samples were prepared and analyzed for the following parameters using standard analytical methods. The parameters include soil texture, Exchangeable cations and anions (H+, Na+, Ca2+, Mg2+, Cl- and SO42-) Nutrients compounds (NO3-, Total Nitrogen (TN), Organic Carbon (OC) and heavy metals (Fe, Cd, As, and Mn). Surface and groundwater samples were collected within the power plant in triplicate and analyzed for true colour, turbidity, conductivity, salinity, THC and Coliform. Dissolved Oxygen (DO), BOD5, Total Organic Carbon (TOC), Organic Matter (OM) and heavy metals (As, Ag, Fe and Mn) of water samples were also analyzed. The soil from the study area is loamy-sand in texture. The average As, Ag, Fe and Mn in surface and groundwater samples were 0.055, 0.025, 3.150, 0.735 and 0.12, 0.080, 6.440 and 0.180 mg/L, respectively. The gas-fired power plant has contaminated the soil and water within its premises with petroleum and heavy metals. The engine stack should be modified to minimize the pollution effects of the power plant on the environment.

Abstract Background The release of environmental pollutants such as heavy metals due to mining activities has received worldwide condemnation. Therefore, understanding the contamination of both surface and groundwater in Edege-Mbeki mining district is very important for the health and wellbeing of its people. Hence, the purpose of this study was to determine the physicochemical parameters of water samples and the level of heavy metals in Edege-Mbeki Columbite/Tantalite (COLTAN) mining site, North Central Nigeria. Results A total of 15 water samples were collected and analyzed in triplicate. The concentrations of five heavy metals (Ni, Mn, Pb, Cd, and Fe) in surface and groundwater samples were measured using atomic absorption spectrophotometer (AA-6800 Shimadzu). The physicochemical properties of the water samples were also examined. The results of the water quality assessments show that the water samples were contaminated with alarming levels of Pb, Cd and Ni. Mean concentrations were Ni (0.008 mg/L), Mn (0.087 mg/L), Pb (0.324 mg/L), Cd (0.029 mg/L), and Fe (0.839 mg/L) in Edege-Mbeki groundwater, while the surface water (mining ponds) had Ni (0.102 mg/L), Mn (0.099 mg/L), Pb (0.358 mg/L), Cd (0.025 mg/L), and Fe (6.99 mg/L). The groundwater samples in Mararaban-Edege which served as the control site had mean concentration levels of Ni (0.032 mg/L), Mn (0.096 mg/L), Pb (0.122 mg/L), Cd (0.039 mg/L), and Fe (0.608 mg/L). The range of pH was found to be from 5.6 ± 0.02 to 6.5 ± 0.12, turbidity was between 39.27 ± 0.29 and 2271 ± 0.00 NTU, and conductivity ranged from 39.27 ± 0.29 to 757.33 ± 5.69 μS/cm, TDS from 25.0 ± 2.3 to 450.67 ± 6.03 mg/L while dissolved oxygen (DO) values from 3.1 ± 0.3 to 3.5 ± 0.3 mg/L. Conclusion This study confirmed that surface and ground water samples in Edege-Mbeki and Mararaban-Edege are not fit for human consumption and other domestic use. Hence, government and community leaders must provide alternative means of water for the people of these communities.

In the present study, both the underground and surface water samples around Guru Nanak Dev Thermal Power Plant Bathinda, Punjab, having total installed capacity of 440MW, were analyzed for the physico-chemical parameters viz. pH, Electrical Conductivity (EC), Total Dissolved Solid (TDS), Total Hardness (TH), Calcium (Ca2+), Magnesium (Mg2+), Total Alkalinity (TA), Carbonate (CO32-), Bicarbonate (HCO3-), Chloride (Cl-), Phosphate (PO43-), Nitrate (NO3-), Fluoride (F-) and heavy metals such as Cadmium (Cd), Copper (Cu), Lead(Pb), Nickel (Ni) and Zinc (Zn). The correlation coefficients (r) among various water quality parameters of studied underground water samples were calculated. The physical and chemical parameters of groundwater are compared with the drinking water quality standards recommended by Bureau of Indian Standards (BIS) (2012) and World Health Organization (WHO) (2017). On the basis of results obtained in the present study, concentration of Chloride (Cl-), Magnesium (Mg2+), Fluoride (F-) and Total  dissolved solids (TDS) observed in ground water of Bathinda varied from 30 to 284 mg/l, 120 to 280 mg/l, 2.66-3.99 mg/l and 620-1439 mg/l, respectively which are exceeding the acceptable limits prescribed by WHO (2017) as well as BIS (2012). Also, the concentration of heavy metals viz. cadmium (0.366 to 0.437 mg/l), and lead (0.193 to 0.353 mg/l) have higher levels than prescribed by WHO and BIS for drinking purpose. Thus, groundwater is not suitable for drinking purposes with prior treatment.

The paper evaluates the presence and content of traces of heavy metals Hg, Pb, Ni, Cd (total forms) from coal and solid combustion products, the degree of transfer and accessibility in the area of influence of a lignite power plant. The content of toxic heavy metals in residues are characterized by RE Meiji [ 1 (Pb and Hg) and REMeij �1 (Ni and Cd) for the filter ash. Pb and Ni content in the soil exceeds normal values, and Pb exceeds and alert value for sensitive soils around the residue deposit (70.20 mg.Kg-1). The degree of accessibility of the metals in plants (TF), reported at the Khan reference value (0.5), indicates a significant bioaccumulation level for the metals: Cd (1.9) and Hg (0.6) inside the deposit; Cd (0.39) at the base of the deposit, Hg (0.8) in the area of the thermal power plant. The trace levels of heavy metals analyzed by GFAAS and CVAAS (Hg), indicates a moderate risk potential for food safety and quality of life in the studied area.

Environmental factors in the form of soil and water quality are the important factors of aquaculture pond productivity, including total production (tiger shrimps, Penaeus monodon, and milkfish, Chanos chanos) in Pasuruan, East Java Province. The objective of this study was to analyze the direct or indirect effects of soil and water quality on the total production of ponds in Pasuruan using a path analysis application. Data were collected in the pond areas around Pasuruan Regency including Nguling, Lekok, Rejoso, Keraton, and Bangil Sub-Districts as well as Pasuruan City. Soil quality was determined as a free variable and exogen; water quality as mediate variable, suspended, and endogen; as well as milkfish production as suspended variable and endogen. Environmental characteristics were illustrated using descriptive statistics, while environment factor effects on total production were analyzed using path analysis. The results of path analysis show that from the 12 analyzed soil quality variables, only two variables were affected in the total production of pond (tiger shrimps and milkfish) namely: contents of soil organic carbon and soil phosphate. While based on 11 water quality variables, two variables (water salinity and water iron) were affected the total production of ponds in Pasuruan Regency. The direct effects of soil organic carbon and phosphate on the total production were 0.314 and -0.600, respectively. Water salinity and water iron gave direct effects on total production amounting to -0.678 and 0.358 respectively. It is also found that two soil variables which were affected in the total production, did not indicate the effect towards water quality in ponds. Further implication of this research is put more attention for these variables into pond’s management in order to gain more production. Technical application could be appropriate for pond preparation and frequently water changing during grow out.

Abstract Background An increase in the urban population and the rising demand for food and other essentials perpetuate a rise in the amount of waste being generated daily by each household. In low-income countries, this waste is eventually thrown into open dump sites. It can cause severe impacts on human health and the surrounding environment. This study was aimed at assessing the effect of a solid waste dump site of Teppi town on surrounding soil and river water quality. Methods A total of three surface water, one leachate water samples, and four soil samples were collected and were analyzed. Six heavy metals for surface water and leachate samples and four heavy metals for soil samples were measured by flame atomic absorption spectroscopy. Additionally, physical and chemical parameters were analyzed using standard methods. The soil and water data were analyzed statistically using Origin pro version 8.0 computer software packages. Analysis of variance (ANOVA) was used to assess whether the mean values of heavy metals and physicochemical parameters in soil and water samples varied significantly between distances and location from the dump site, possibilities less than 0.05 (p< 0.05) was considered statistically significant. Results pH of soil was slightly basic (pH 8±0.1 up to 8.7±0.21. Similarly, EC was lower in 60 meters (1800±0.5μs/cm) and higher in the other sample sites (3490±0.66-4920±1.04μs/cm). The concentration of heavy metals such as cadmium (0.53±0.01-2.26±0.02 mg/kg), zinc (623.93±0.29-859.41±0.02mg/kg), lead (3.26±0.25-57.560.26mg/kg), and copper (204.06±0.06 337.11±0.01mg/kg) in the sample soils has been found to be higher than Ethiopian EPA and USEPA guideline values. Lead, cadmium, manganese, nickel, copper, and zinc in the leachate water and nickel and manganese in nearby river water, total dissolved solid, BOD5, chemical oxygen demand, and turbidity for both leachate and stream water samples were found to be higher than the Ethiopian EPA and WHO standard guideline values. Conclusions The finding suggested that solid waste open dump site adversely affects soil and water quality in the study area and probable source of human health risks via the food chain. The soil in the area requires Phytoremediation technologies. In addition, sanitary landfill is recommended.
