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

Abstract

Abstract: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.

Status of Water Used for Drinking and Irrigation in Kano: A Critical Review on Physicochemical and Heavy Metals Concentration

“…A research was undertaken by Nahannu et al, [72]; Shawai et al, [73] in Gezawa, Nigeria to have an idea of the extent of ground water pollution due to contamination with industrial effluents as well as sewage wastes. Shawai et al, [60] Physicochemical and bacteriological analyses were carried out on well water samples from eight selected locations within the industrial area of Kano Metropolis including Bompai, Sharada, Challawa and Jaba [19].…”

“…The EC, concentration of chloride, sodium, calcium, magnesium, TDS, sodium adsorption rate (SAR), and sulphate recorded in the water samples lies in the impermissible limit sets by WHO and Food and Agricultural Organization (FAO), and the concentrations of carbonate, bicarbonate, nitrate and boron are unsuitable for irrigation purposes as recommended by WHO and FAO. A research was undertaken by 11,12 in Gezawa, Nigeria to have an idea of the extent of ground water pollution due to Human activities are a major factor determining the quality of surface and groundwater through atmospheric pollution, effluent discharges, use of agricultural chemicals, eroded soil and land use.The purpose of this research was to determine the physicochemical parameters of water samples collected from Sa'adatu Rimi College of Education, Kumbotso Kano and to compare with the standards given by World Health Organization (WHO) and Nigeria Standard for Drinking Water Quality (NSDWQ). Four samples were collected from different locations within the college premises for the analysis.…”
