QUALITATIVE EVALUATION OF GROUND WATER FOR ABU- KHAMES VILLAGE / DAYALA AND ITS SUITABILITY FOR HUMAN USE

Abstract

The subject of water pollution became the most topics that attracts researchers to study andidentify 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 villagegroundwater wells and determine its validity for human use, where it was laboratory analysisduring the period (12/2010) to (2/2012).This investigation has included the estimation of inorganic elements concentrations by standardanalysis methods, which was divided into two groups of elements, the first group includesinorganic metals, which have a direct impact on taste and household uses, which includecalcium, magnesium, sulfate, chloride, sodium, potassium, turbidity, total hardness, totaldissolved salts, electrical conductivity and pH.The second group includes inorganic and heavy elements that have a direct impact on publichealth and include iron, copper, cadmium, nitrates, lead and nickel.This study found that the drinking water indicated a direction of the baseline. Turbidity valuesdid not record any significant increase during the period of testing, and this is the same for thecase of magsium, calcium, chloride, sodium and potassium because they were all within thepermissible international limits.In the opposite direction, total hardness, total dissolved salts, electrical conductivity and sulfidesrecorded high levels of concentrations for most of months upper than accepted limits. The testedwater 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 ofiron, copper and nitrate were within the specifications, while, there is an altering increase in theconcentrations of cadmium with average readings (0.047 ppm), and (100%) increasing than thespecific limit, and this was caused by several reasons such as the candidacy of cadmium fromchemical 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 someof anomalous readings, which were accompanied by a rise in total hardness.Finally, most of nickel readings were ranged below permissible limit, except two readingsrecorded in summer, and that is attributed to increasing in temperature and rate of corrosion inthe carrier pipes, and this is confirmed by the statistical analysis with positive significantcorrelation factor between them.
