Abstract
Present investigation was carried out on groundwater in Unguwa Uku for water quality parameters during October, 2016. Parameters such as total hardness (TH), alkalinity, electrical conductivity (EC), turbidity, pH, temperature, chloride, calcium, free CO<sub>2</sub>, suspended solids (SS), total suspended solids (TSS), total dissolve solids (TDS), colour, and odour were analyzed from five locations. The analysis were carried out using standard analytical methods. The analysis of data reveals that, the value of free CO<sub>2</sub> ranges from 9- 104 mg/L, 36.05- 72.10 mg/L for Calcium, 2-13 NTU for turbidity, 583.59-2065.03mg/L for total hardness 7.1-8.3 for pH, 21.7-23.4°C for temperature, 202-970 mg/L for TDS, 250-305 mg/L for alkalinity, 405-1939µS/cm for conductivities, 5TCU for colour, 111.70-659.51mg/L for suspended solids, 669.03-1255.51mg/L for total suspended solids, 106.57-296.10mg/L for chloride. The results obtained revealed that, the values of alkalinity, TDS, TSS, SS, pH, temperature, colour, odour, free CO<sub>2</sub>, and concentrations of Calcium of the water samples analyzed are within the acceptable limits set by World Health Organization (WHO) and Nigerian Standards for Drinking Water Quality (NSDWQ) for the drinking water. The values of electrical conductivity and total hardness are above the maximum permissible limits and may have adverse effects on the human health of the study area. However, not all the values of turbidity and chloride in the samples are within the acceptable limits of WHO and NSDWQ in the drinking water. This paper also recommended that, government and non-governmental agencies should make reasonable effort to control, regulate and educate the people in the study area for proper disposal of domestic effluents.
Highlights
Man’s activities on earth are significantly influenced by availability of and accessibility to the quality water for domestic, agricultural as well as other purposes
The concentration of some physicochemical parameters in water samples from the five sampling point in Unguwa Uku are presented in table 1 below: Table 1
The result obtained shows that the alkalinity, total dissolve solids (TDS), pH, temperature, total suspended solids (TSS), SS colour, odour, free CO2, concentration for calcium and chloride average values of the water samples analyzed are within the acceptable limits set by World Health Organization (WHO) [15, 26] and Nigerian Standards for Drinking Water Quality (NSDWQ) [14] for the drinking water, on the other hand, the mean values of electrical conductivity (EC), and hardness are above the maximum permissible values and may have adverse effect on human health of the study area
Summary
Man’s activities on earth are significantly influenced by availability of and accessibility to the quality water for domestic, agricultural as well as other purposes. The quality of water is of vital importance to making since it is directly linked with human health [2]. According to [2] the quality of groundwater is important to its quantity due to the suitability of water for various purposes which include drinking, domestic, industrial and agricultural purposes. [3,4,5] Reported that, 10 million people die because of drinking contaminated water or water off less quality every year. These are the factors why water quality studies have been receiving a special consideration at several points in time by different scholars and researchers [3]
