井下水的物理化学研究和细菌化验Ezinihitte Mbaise当地政府的国际海事组织状态,尼日利亚东南部,是提供基线数据和评价农村供水的可移植性。水样收集从11个钻孔位于不同的城市地方政府区域分析,使用不同的标准方法。化学参数的值一式三份各种水样的分析显示,mg / L范围如下异常的pH值,4.56到6.36;和电导率,10.89到57.40μs / cm;因此,总固体量,10到90;总溶解固体,6.4到34.5;硝酸,0.6到2.9;磷酸,0.01到0.02;硫酸,0.05到0.13;总酸度,0.76到40.32; total alkalinity, 0.5 to 24.5; total hardness, 12.0 to 38.0; chloride, 0.5 to 9.5; sodium, 5 to13; potassium, 1 to 4; calcium, 4 to 32; magnesium, 2 to 7. Lead, cadmium and chromium were not detectable in all the water samples. Detectable levels of other trace metals were: copper, 0.01 to 0.19 mg/L; nickel, 0.1 mg/L; iron, 0.01 to 0.25 mg/L and zinc, 0.01 to 0.15 mg/L. Total viable count for bacteria showed heavy growth of E. coli in eight boreholes. The range was from 0.12 x 102 to 2.56 x 102 cfu/100 mL. Compared with WHO guideline values for drinking water, pH range 4.56- 6.36 fell below the range of 6.5-8.5. The heavy metals did not exceed the stipulated guideline values, but the growth of bacteria impairs the quality of the water in eight boreholes. However, for assurance of safety, water needs to be boiled before drinking.
