When liquid percolates through the waste mass, leachate is produced. It has numerous hazardous components that, when released into the environment, lead to numerous health issues. The goal was to evaluate the leachate quality at Accra's Sarbah landfill site in preparation for potential treatment. The biological oxygen demand (BOD), chemical oxygen demand (COD), and oil and grease concentrations were all substantial in the alkaline leachate. Several locations close to the landfill were used to collect leachate samples. Except for Fe, which was quite high, heavy metals like Cd, Zn, Pb, Mn, Cr, Hg, and Cu, and their pollution, were within the Environmental Protection Agency of Ghana's (EPA) guideline levels. According to the study, leachate may contaminate nearby water bodies. The leachate contained microorganisms, some of which have negative effects on public health. The most frequent pathogens identified in the leachates of the Sarbah dumpsite were total coliforms (TC), faecal coliforms (FC), Escherichia coli, Salmonella spp, Vibro spp, Bacillus spp, Yeast, and Moulds. The EPA's permitted limits for TC and FC were all exceeded at the sites due to their high concentrations. The sites with the highest concentrations were I (TC, 26 x106 CFU/100 ml; FC, 33 x 105 CFU/100 ml), and IV (TC, 18.6 x 102 CFU/100 ml; FC, 38.4 x 10 CFU/100ml). E. coli (22.4 x 105 CFU/100 ml), Salmonella (41 x 103 CFU/100 ml), and Vibro spp. are specific bacteria pathogens. There were (12 x 10 CFU/100 ml) at site I but none at site II. Among the illnesses that could be transmitted through the leachate by the principal biological contaminants are gastroenteritis, typhoid fever, dysentery, salmonellosis, cholera, malaria, intestinal worms, and upper respiratory infections.
