Abstract
physicochemical and bacteriological assessment of groundwater from nine
boreholes in College of Education, Katsina-Ala was conducted to evaluate its
Asuitability for human consumption. Standard analytical methods were used to test
physical, chemical, and microbial parameters. pH values ranged from 6.49 to 8.69, with most within World Health Organization and Standard Organization of Nigeria is permissible limits. Electrical Conductivity (200–354 µS/cm) and Total Dissolved Solids (TDS) were within acceptable limits, except at Apa hostel, which slightly exceeded the TDS threshold. Alkalinity and Total Hardness were within safe ranges. Magnesium was mostly undetected, and when present, remained below the SON guideline. Sulfate, chloride, fluoride, and nitrate levels also complied with standards. No toxic heavy metals (e.g., lead, cadmium, chromium) were found; zinc and iron levels were within safety range. Bacteriological analysis confirmed the absence of E. coli, faecal streptococci, Clostridium perfringens, and total coliforms. The study concludes that the groundwater in College of Education Katsina – Ala is generally safe for drinking, though periodic monitoring is recommended.
