Abstract

This study aimed to clarify the hygienic quality of groundwater samples collected from multiple wells from Al-Dakhla city, The New Valley, with special reference to heavy metals pollution. Groundwater samples from 10wells were investigated (3 samples each). Metals concentrations were determined using the ICP [Inductively Coupled Plasma Emission Spectrometer (ICAP 6200)]. The results revealed that the levels (ppm) of estimated metals were 0.803±0.011 (0.250-3.033) for Pb; 0.0082±0.0008 (0.0001-0.0325) for Cd; 30.595±0.197 (4.225-56.325) for Mn; 326.233±3.077 (27.75-512.75) for Fe; 0.375±0.002 (0.150-1.125) for Cu and 9.256±0.222 (5.150-14.833) for Zn. The levels of tested water chemical parameters were 1476.380±14.711 (441.6-2028.8) mg/l for TDS; 2.307±0.061 (0.690- 3.170) dc/m for EC; 6.186±0.082 (5.4 - 6.7) for pH and 467.5±13.352 (275-525) for TH.It is found that lead, iron, manganese and zinc mean values are exceeding the MCL (maximum contaminant level) in 100%of the examined wells. However, copper recorded mean values within the permissible limits listed by each of Egyptian Standards (2007), EPA (2009), WHO (2011) and EU (2014). Eighty percent of examined wells showed total dissolved solids higher than the limits of Egyptian Standards (2007), EPA (2009), WHO (2011). Eighty percent of examined wells recorded EC in higher levelsthan Egyptian standers (2007). Total hardness exceeded the permissiblelevelsin 100% of the examined wells while pH values were all in the acidic range which was slightly around the permissible limits.
