Heavy metal pollution of aquatic ecosystems poses a significant environmental issue, particularly in rivers exposed to industrial and domestic effluent discharges. This study assessed the physicochemical characteristics of water and sediments from Wupa River, Abuja, Nigeria. Three stations were selected to represent different levels of anthropogenic impact: Station 1 (upstream, reference site), Station 2 (effluent discharge point from Wupa wastewater treatment plant), and Station 3 (downstream of the discharge). Water and sediment samples were collected in triplicates and analyzed using standard methods and procedures. Key water quality results included temperature (28.00–29.33 °C), pH (7.81–8.06), conductivity (0.15–0.20 µS/cm), turbidity (5.92–7.57 NTU), chloride (105.32–118.71 mg/L), nitrate (17.92–20.86 mg/L), sulphate (0.15–0.27 mg/L), and chemical oxygen demand (1.52–2.32 mg/L). Detected heavy metals in water included cadmium (0.10–0.12 mg/L), copper (0.010.04 mg/L), iron (0.57–0.83 mg/L), nickel (0.11–0.15 mg/L), lead (0.98–1.04 mg/L), and zinc (0.02–0.03 mg/L). Sediment analysis revealed copper (0.13–0.28 mg/L), nickel (0.02–0.18 mg/L), zinc (0.03–0.05 mg/L), cadmium (0.004–0.01 mg/L), lead (5.09–5.69 mg/L), and iron (2.00–5.65 mg/L). The elevated levels of lead and iron in sediments, and detectable concentrations of cadmium and nickel in water, suggest significant contamination associated with effluent discharge. These findings highlight the need for effective wastewater management and regular monitoring to safeguard aquatic ecosystems and public health in communities dependent on the Wupa River.
Investigation of Bacteria Biostimulation Strategy for Heavy Metal Bioremediation in Wupa Wastewater Treatment Plant, Abuja

Heavy metal pollution in water systems disrupts ecosystems and poses serious public health risks. Bioremediation remains the most cost-effective and eco-friendly, relying on naturally occurring microorganisms to degrade or transform toxic contaminants. This study was aimed at stimulating microbial isolates from Wupa Wastewater Treatment Plant (WWWTP) with nutrients to remove heavy metals from effluents obtained. Wastewater samples collected from Wupa WWTP were analyzed for physicochemical parameters, including pH, electrical conductivity, turbidity, temperature, BOD, COD, TSS, TDS, and concentrations of zinc (Zn), manganese (Mn), and iron (Fe), using standard methods. Bacteria and fungi were isolated microbiologically, and a nine-day container experiment was conducted with four nutrient setups containing different concentrations of peptone (150 ml, 75 ml) and glucose (9 g, 4.5 g) to enhance microbial degradation capability. Biomass growth was monitored every three days using a UV spectrophotometer. The results revealed that physicochemical parameters of the treated and untreated wastewater exhibit significant differences (p<0.05), except for pH and temperature. All physicochemical parameters showed significant differences (p < 0.05) between treated and untreated wastewater, except pH and temperature. Heavy metal concentrations also differed significantly (p < 0.05), with Mn decreasing from 0.37±0.20 mg/L (untreated) to 0.31±0.10 mg/L (treated), Fe from 1.58±0.2 mg/L to 0.91±0.3 mg/L, and Zn from 0.501±0.10 mg/L to 0.501±0.10 mg/L. Eight bacterial species were isolated. The biostimulated microbial consortium effectively remediated Mn, Fe, and Zn by 66.8%, 60.5%, and 70.2%, respectively. This study demonstrates promising potential for heavy metal removal from wastewater treatment plants and industrial effluents.
