Abstract

Twelve water samples were collected around the Odukpani-Akamkpa southeastern Nigeria. The goal was to assess the drinking water sources in the farming and quarrying land use areas. This was achieved by determining hydrochemical facies, water types and suitability of the water quality for domestic, irrigation and other uses. Concentrations of Fe, Mn, As and NH4+ recorded mean values that exceeded acceptable limits for potable water using potable water guidelines and are potentially toxic elements. Ferruginous waters rust borehole installation materials, impart reddish colour while arsenic is carcinogenic. (NH4+) recorded the highest cationic mean value in the water samples. The ionic ratios: Na+/Ca2+, HCO3−/Cl indicated fresh water condition. The ionic ratio values of Cl−/HCO3−, CEV and Mg/Ca2+ show that the groundwater is of low salt inland origin. The water type in the study area is HCO3−, Na+K and Cl-SO42−, Na+Mg. Cations trend as: NH4+>Ca2+>Mg2+>Na+>K+. Anions trend in the order HCO3−>Cl−>SO42−>NO3−.

尼日利亚东南部Akamkpa及其周边沉积物-基底接触带的水文地球化学质量和特征

在尼日利亚东南部的Odukpani-Akamkpa周围收集了12个水样。目的是评估农业和采石用地区内的饮用水源。这是通过确定水化学相、水类型和水质是否适合家庭、灌溉和其他用途来实现的。铁、锰、砷和NH4+的浓度平均值超过了使用饮用水指南的饮用水可接受限度，是潜在的有毒元素。含铁的水使钻孔安装材料生锈，而砷则致癌。水样中阳离子平均值最高的是NH4+。离子比:Na+/Ca2+， HCO3−/Cl表示淡水状态。Cl−/HCO3−、CEV和Mg/Ca2+的离子比值值表明地下水为低盐内陆源。研究区水类型为HCO3−，Na+K和Cl-SO42−，Na+Mg。阳离子趋势为:NH4+>Ca2+>Mg2+>Na+>K+。阴离子趋势为HCO3−>Cl−>SO42−>NO3−。
