    An Assessment of Groundwater Quality in Tudun Fulani, Niger State, Nigeria
    (Sule Lamido University Journal of Science and Technology (SLUJST), 2020-12) Bisiriyu, Muhammad Taoheed; Ganiyu, Mustapha Adekomi; Audu, Lawal Idris; Abdullahi, AbdulHakam Safiu; Animashaun, Iyanda Murtala
    groundwater is the main source of drinking water in Tudun Fulani community in Bosso, Niger State, Nigeria. Objective: this study was conducted to assess the physicochemical and heavy metal characteristics of groundwater used for drinking and other domestic purposes in the area with a view to determining its suitability for these purposes. Method: twelve water samples comprising of seven hand-dug wells and five boreholes were collected from different locations in the area. Physicochemical parameters (pH, turbidity, electrical conductivity, total dissolved solids (TDS), total suspended solids (TSS), total solids (TS), alkalinity, total hardness, chloride) and heavy metals (lead, manganese, copper and iron) contents were determined using standard methods. Results: the results showed that the pH, electrical conductivity, TDS, TSS, TS turbidity, alkalinity, total hardness and chloride ranged between 5.72 – 7.32, 252.5 – 1098 μS/cm, 58 – 11.35 mg/L, 0.001 – 0.108 mg/L, 1.05 – 7.33 NTU, 10.60 - 104.20 mg/L, 26.6 – 170.2 mg/L, and 28.17 – 86.9 mg/L, respectively. The heavy metal analysis revealed lead, manganese, copper, and iron to range between 0.001-0.009 mg/L, 0.01-0.28 mg/L, 0.010 - 0.050 mg/L and 0.100 – 0.430 mg/L, while manganese and lead were not detected in one and six of the samples, respectively. Conclusion: the values of the parameters analysed in this study were below and within the permissible limits set by the World Health Organisation (WHO) for most of the water samples investigated; hence, the groundwater is suitable for drinking and for other life-supporting activities. However, only four samples (W1,W5 W6, and W7) were within the range of 100 - 300 mg/L set by WHO for total hardness. In addition, the pH values of water samples W4, W5, B4, and B5 were below the recommended standard, while the electrical conductivity of W5, turbidity of W3, W5 and iron contents of W2 and W7 were above the maximum limit set by WHO. Therefore, it is recommended that the indiscriminate discharge of wastes be checked in locations of W2 and W7 as high iron content in drinking water poses serious health risks to consumers.

    Quality Evaluation of Bottled Water Packaged within Niger State, Nigeria
    (Nigerian Research Journal of Chemical Sciences, 2020) Bisiriyu, Muhammad Taoheed; Ganiyu, Mustapha Adekomi; Ogwuche, Nelson Edache; Koleola, Abidemi Adedayo; Salau, Rasaq Bolakale
    Ten different brands of bottled water were procured from different regions of Niger State, Nigeria for this study. The labeling information, temperature, pH, turbidity, electrical conductivity, total hardness, chloride, alkalinity, lead, copper, manganese and iron contents of the water samples were determined using standard methods. The investigation revealed that the temperature, pH, electrical conductivity, total hardness, chloride and alkalinity of the samples ranged between 26.5+0.50–28.0+0.00 oC, 6.20+0.09–7.33+0.30, 13.5+1.50– 317.5+1.50 µScm-1, 13-125 mg/L, 2.89 - 31.36 mg/L and 5-60 mg/L, respectively. Lead and copper were not detected in all the samples except SB10 with 0.01 mg/L of copper. Similarly, manganese was detected in six samples at concentrations between (0.02-0.08 mg/L) while iron ranged between 0.01-0.16 mg/L). The physical, chemical and heavy metals composition of the water samples complied with World Health Organization (WHO) and Standard Organization of Nigeria (SON) permissible limits for drinking water except the pH of one sample (SB8) that was below the permissible limit. However, 60% of the brands had no manufacturing and expiry dates on their label as required by the Nigeria’s National Agency for Food and Drug Administration and Control (NAFDAC). Therefore, periodic evaluation and monitoring by concerned agencies should be intensified to ensure that bottled water producers in the state strictly adhere to the standard operating procedures
