摘要：The burgeoning of slums in the developing world poses an urgent environmental threat due to insanitary conditions and rampant disposal of wastewater. To assess the potential environmental impacts, domestic wastewater from Ghana's biggest urban slum -Old Fadama was characterised throughout the dry and wet seasons. The study drew on a comprehensive assessment of the general sanitary conditions in the community to determine the sources of pollution and water quality monitoring. BOD5levels of wastewater from the study area were 545.63¡À99.88mg/L and 645.94¡À331.43mg/L in the dry and wet seasons respectively whereas COD levels were 1100.45¡À167.16mg/L and 1415.12¡À722.83mg/L in the dry and wet seasons respectively. E-colilevels were 4¡À1x106CFU/100mL and 4200¡À2400 x106CFU/100mL in the dry and wet seasons respectively whereas total coliform levels also showed the same trend with 9¡À2106CFU/100mL and 16800¡À5100106CFU/100mL in the dry and wet seasons respectively. The study identifies that wastewater from this community has potential deleterious environmental implications due to high levels of nutrients, oxygen-demanding substances and faecal coliforms. Pollutants were identified to be emanating predominantly from open defecation and indiscriminate waste disposal. Efforts should thus be directed towards improving sanitary conditions viz. access to toilet facilities, waste disposal mechanisms and best management practicesfor wastewater.
