The aim of the study was to analyze some of the parameters and compare the results with standard values recommended by WHO. The samples taken from six different locations at least 1km apart revealed that the study area has a mean of Turbidity 2.4NTU, Colour 5.8Hazen unit, Temperature 27.7 0 C, PH 6.98, Alkalinity 5.3mg/L, Hardness 39.08mg/L, Biochemical oxygen demand (BOD) 0.13mg/L, Total dissolved solid (TDS) 221.75mg/L, Suspended solids (SS) 12.5mg/L, Conductivity 7.64μs/cm. By observing the results, it was shown that the parameters from the water samples were within WHO permissible limits which satisfies the safety limit for its use for various purposes like domestic, agricultural, industrial and so on.

INTRODUCTION Rapid urbanization, especially in developing countries like Nigeria, has affected the availability and quality of groundwater due to waste and effluent disposal practice, especially in urban areas. This can be evidenced from African and Asian countries that experience rapid industrial growth, thus, making environmental conservation very difficult (Agarwal and Animesh, 2011). Researchers’ workers such as Kalyana et al., (2014), Adefemi and Awokunmi (2010), Ezeribe, Oketunda and Shaato (2011) who studied some physicochemical parameters of ground water from industrial areas of Pydibheemavaram, Vizianagaram and Andhra Pradesh Districts, India have indicated such. Eight ground water samples were taken from boreholes and open wells and were analysed for pH, EC, Chloride, Total Alkalinity, Total Dissolved Solids (TDS) and Total Hardness. The results were compared with WHO standards. Similarly, the study of Murhekar and Gopalkrushna (2010), who carried out, an assessment of physico-chemical status of ground water samples in Akot city also analyzed for * Corresponding Author Email: samaila.muazu@umyu.ed temperature, pH, TDS, dissolved oxygen turbidity, total alkalinity, total hardness, Ca 2+ , Mg 2+ , Na + , K + , Cl - , F - , NO 3 - SO 4 - and PO 4 - of open and Bore wells. No hazardous level of contamination was detected in all samples analysed except few sites with little contamination. The physic chemical and bacteriological studies on ground water have also indicated some level of contamination as reflected in the report of Ahmed and Eyaife (2014) who conducted same physicochemical and bacteriological quality of ground water at Abubakar Tatari Ali polytechnic Bauchi, Nigeria. The results revealed that the samples contained some contaminants like bacterial contaminants in excess of the recommended limits set by NSDWQ and WHO. The correlation between the level of various parameters analysed showed positive correlation as indicated by the study of Chandrakar, (2017), Gabriel, et al. (2010), who developed linear regression equations to predict the concentration of water quality among the various parameters analysed. The TDS and EC have perfect correlation coefficients whereas Na + and Cl - , were also highly correlated in all the water sources. Furthermore, while Ca 2+ and HCO 3 are highly correlated in both the shallow and deep groundwater they have relatively lower correlation coefficients in the surface
