Water samples collected from boreholes close to a dumpsite in Rumuolumeni, Port Harcourt in the months of January, April, August and November were analyzed for physicochemical properties and heavy metals using APHA standard methods. The data obtained did not reveal any significant changes between the months and the seasons. Temperature values were within the WHO standard but higher than the FMENV requirements in all the sample points. pH values were lower than the standard requirements by the relevant agencies and are unacceptable. The values for conductivity, hardness and alkalinity were below the acceptable limits by WHO, NAFDAC and FMENV. Total dissolved solids (TDS) values in the sample points were above the standard requirements by the agencies (WHO, NAFDAC AND FMENV). Biochemical oxygen demand (BOD) values obtained in the sample points were below the standard requirements except at Pt. III where a value of 4.13±1.48 mg/L was observed. The values of the anions chlorides (Cl-) and nitrates (NO3-) were below the standard requirements by the agencies, while those of phosphates (PO4-) were higher than the recommended values in the sample points. The cations Manganese (Mn), Lead and Cadmium (Cd) were higher than the recommended values by the agencies (WHO, NAFDAC and FMENV.) Iron (Fe) values fell within the WHO requirements in the sample points but were above the NAFDAC and FMENV values in those points. Cobalt (Co) values were lower than the standard requirements from the relevant agencies. The observed result is an indication of water contamination. The dumpsite may have impacted on the water quality. Therefore the water is not suitable for drinking since it can constitute a source of health risk and hazard.
