ABSTRACT This article presents results of groundwater quality assessment based on some pollution indicators (pH, conductivity, total dissolved solids, total suspended solids and turbidity) carried out in Michael Okpara University of Agriculture, Umudike, Abia State, Nigeria. Twelve functional boreholes within the university campus and its environs were sampled and analyzed using the standard laboratory techniques. The results showed that the groundwater in the area was acidic with an average pH value of 5.47, which falls below the World Health Organization (WHO) standard for drinking water. The results also showed high turbidity values ranging from 86.10 to 90. 17 NTU which exceeds the WHO standard. The waters have moderate to high values of total dissolved solids, TDS (100.00 to 900.00 mg/L), total suspended solids, TSS (100.00 to 1200.00 mg/L) and conductivity (66.67 to 600.03 µs/cm). Recommendations include periodic groundwater monitoring and treatment.
