The major source of water in Kafin Hausa is ground water. The flooding experienced annually coupled with the indiscriminate disposal of agricultural and domestic waste had aroused the need for this research. The aim of this study was to determine the concentration of phosphate, nitrate and phenol in boreholes water in Kafin Hausa Local Government area of Jigawa State Nigeria. Seven samples were collected from boreholes located at Turawa, Magaman Ashura, Fanisau, Gambawa, Kofar-Fada, Kiginawa and ‘Yan Gobir quarters of Kafin Hausa Local Government area of Jigawa State. The analyses were carried out using UV-Visible spectrophotometer. From the results, it was found that the samples had a mean phosphates concentration of 3.74 ± 0.002 mg/L which was above the World Health Organization maximum contaminant limit of 0.03 mg/L. Nitrate has a mean concentration of 2.01 ± 0.01 mg/L which was below the World Health Organization tolerable limit of 50mg/L. The mean levels (0.0299 ± 0.00) of phenol were found to be slightly below the tolerable limit set by WHO (0.03 mg/L). Phosphate has been implicated for eutrophication, nitrate lead to methemoglobinemia (baby blue syndrome).
