Abstract
The subject of water pollution became the most topics that attracts researchers to study and identify this danger and introduce the appropriate solutions for water with direct human use, therefore, this study tended to assess the quality of drinking water of Abu- Khamis village groundwater wells and determine its validity for human use, where it was laboratory analysis during the period (12/2010) to (2/2012). This investigation has included the estimation of inorganic elements concentrations by standard analysis methods, which was divided into two groups of elements, the first group includes inorganic metals, which have a direct impact on taste and household uses, which include calcium, magnesium, sulfate, chloride, sodium, potassium, turbidity, total hardness, total dissolved salts, electrical conductivity and pH. The second group includes inorganic and heavy elements that have a direct impact on public health and include iron, copper, cadmium, nitrates, lead and nickel. This study found that the drinking water indicated a direction of the baseline. Turbidity values did not record any significant increase during the period of testing, and this is the same for the case of magsium, calcium, chloride, sodium and potassium because they were all within the permissible international limits. In the opposite direction, total hardness, total dissolved salts, electrical conductivity and sulfides recorded high levels of concentrations for most of months upper than accepted limits. The tested water can be classified as Brackish water after the calibration with (Todd) test. The second set of tests involved heavy elements, where, it was found that the concentrations of iron, copper and nitrate were within the specifications, while, there is an altering increase in the concentrations of cadmium with average readings (0.047 ppm), and (100%) increasing than the specific limit, and this was caused by several reasons such as the candidacy of cadmium from chemical fertilizers and as a result of corrosion made in the interior of pipes. Concerning lead, most of its concentrations were within permissible limit, but there were some of anomalous readings, which were accompanied by a rise in total hardness. Finally, most of nickel readings were ranged below permissible limit, except two readings recorded in summer, and that is attributed to increasing in temperature and rate of corrosion in the carrier pipes, and this is confirmed by the statistical analysis with positive significant correlation factor between them.
