The flame atomic absorption spectrophotometry was used to analyze the level of chemical concentration in the borehole water sample whereas a physical visibility survey was used to ascertain the quality of the borehole. Groundwater using the parameter in comparison with WHO permissible limits. A total of five (5) groundwater samples were collected in triplicates from public boreholes located at IBB way, Mechanic Village, Uyo Urban, Nwaniba road and Ewet Housing Estate. The data for previous analysis was gotten from the Ministry of Science and Technology, Uyo and new analysis was conducted on recent samples gotten from the five stations. The groundwater samples were analyzed in the laboratory for their physical, chemical and microbiological characteristics. On comparing the results with standard values recommended by World Health Organization (WHO), it was discovered that most of the groundwater samples were within permissible limits with slight variation across the locations. However, the pH of the groundwater samples was not within the permissible limit of 6.50mg/l – 8.50mg/l in three different locations which are Nwaniba, Uyo Urban and Mechanic Village with pH values of 5.57, 5.14 and 5.00. Total hardness of the groundwater samples with values of 43.0 mg/l, 12.0 mg/l, 15.0 mg/l, 5.0 mg/l and 59.0 mg/l respectively. Several other parameters also got slight differences. The study found out that minimal treatment is required in the study area and recommends continuous monitoring of the groundwater supply to keep the quality in check.

INTRODUCTION In recent times, borehole has become the main source of water supply in rural, semi-urban and urban areas, this was stated by Offodile (2002). The seasonal variation in water quality is found associated with climatic factors (hydrological and biochemical processes) and flow regulation. Adekile and Olabode (2009) provides a history of borehole development in Nigeria and this is summarized in this section as follows: Before colonization and up to independence, most of the borehole abstraction was from unlined hand-dug wells. Between 1930 and 1933 the Geological Survey of Nigeria experimented and perfected the 1.2 m diameter lined dug well. In 1947, the Public Works Department took over the construction of rural water supplies. A cable tool rig was purchased and the first rural boreholes were constructed. Rotary water drilling was introduced into the country by Balakhany Chad, a British company in 1951 mainly for drilling in townships.
