Physicochemical Analysis of Groundwater Samples in Gezawa Local Government Area of Kano State of Nigeria

The physic-chemical parameters of Groundwater from various locations in Gezawa Local Government Area of Kano State were analyzed using standard methods. The samples taken from ten different locations revealed that the study area has a mean of Alkalinity 79.0 mg/l, temp. 21.64°C, turbidity 5.9NTU, total hardness 65.54 mg/l, pH. 7.13, total dissolved solid 56.54 mg/l, conductivity 111.31 us/cm and total suspended solids 5.2mg/l. As the results indicated all the physicochemical parameters are within the maximum contaminant levels set by standard organization of Nigeria (SON), Nigerian Standard for Drinking Water Quality (NSDWQ) and world health organization (WHO) except for turbidity level in Babawa and Dansarai sampling sites which are close to Wase Dam. However, since some of the results indicate high levels above the standard set by WHO, NSDWQ and SON safe limits there is the tendency of high potential health hazards to the inhabitants of the areas that uses these water sources for drinking and other domestic purpose without treatment. As the results indicated, some of the parameters analyzed showed higher concentration above the WHO, SON and NSDWQ contaminant level especially the sampling sites very closer to Wase Dam which is believed to be contaminated, the following steps are recommended for lowering the concentration, heating the water before used can remove the temporary hardness. Domestic and industrial waste should be properly disposed or recycled. Relevant agencies should make concerted effort to control, regulate and educate the community on indiscriminate waste disposal from domestic and industries within the study area and also further research should be carried out to assess the level of some other parameters.
