为了确定该城市是否适合饮用或至少适合灌溉，评估了从不同井中收集的水的化学成分。这项研究表明，大部分的化学参数，如。钡、镉、铬、锌;铁不在允许的限度之内。从不同井中采集的水的阴离子差异很大。Cl^-在32 - 955 mg L^-1之间变化，高于EPA标准(200 mg L^-1)。NO₃^-2范围为14.6- 2088 mg L^-1，远高于EPA允许水平(10 mg L^-1)。同样,,10口井中有3口井的NH₄相对高于10mg L^-1。阳离子也表现出类似的趋势，从一些井中采集的样品中阳离子的浓度最大，而从其他井中采集的样品中阳离子的浓度更低，甚至BDL。 Na⁺ and Mg⁺ exceeded the standard levels (200 and 30mg L^-1 respectively). K⁺ was lower than EPA standards of 30 mg L^-1 in all samples Five metals out of the 10 elements analysed in the water samples from suburban water wells were found in concentrations exceeding various standards, which are Al, B, P , Cu and Pb However other trace metals (Fe, Ba, Cd, Cr and Zn) were not detected in all water samples.
