Assessment of Ground Water Pollution by Heavy Metals and Anions in Kwashe Industrial Area, Duhok City, Kurdistan Region. Iraq
2018-08
IOP Conference Series: Materials Science and Engineering
Kwashe industrial area in Summel district, Duhok city, Kurdistan region-Iraq is
relatively new and considered the only industrial area in Duhok city which include various
factories such as petroleum refineries, dying, tanning, cement, recycling of steel in addition to
large municipal waste separating factory that produce huge amount of wastes in huge landfill
with high leachate. Therefore ten artesian wells were chosen nearby and downward industrial
area to study the impacts of industrial effluents and landfill leachate in contaminations of these
wells. The results showed. The sulfate content is under risk limit of WHO (3-150 μg/L) in
ground water, but there is evidence that a little contamination plume is created in Girresh 28.63
± 1.25 mg/L location. The Cl as typical recommended by WHO in ground water is 1-70 mg/L
and are low in 5 artesian wells upper industrial are and magnified in the rest 5 artesian wells
downward industrial area and high levels recorded in Girrash 30.33 ± 1.53 mg/L. WHO
standard of NO3 in ground water is 2-20 mg/L, the locations Kwashe 3, 4, 5 is better site of
NO3 in upper industrial area ranging between 5.13 ± 0.15 to 5.50 ± 0.20 and the third wells
are save for drinking according WHO standards which must be under 10 mg/L are Kwashe 1, 2
and Sarshour ranging between 9.67 ± 0.1 and 9.70 ± 0.20 mg/L. The rest four wells Girresh,
Marina, Moqeble, and Sarshour located down ward industrial effluents and landfill leachate are
significantly affected toward increasing to reach hazardous levels in three location Sarshour
19.70 ± 1.45 mg/L, Marina location 22.67 ± 0.85 mg/L and the center of toxin plume recorded
in Girrish of 55.33 ± 0.25 mg/L which is not save as drinking water for adults and Cattle
babies according WHO standards. The typical soil properties like high pH values 7.9 ,huge
amount of active/total CaCO3 % 62.62 and high clay content 381.68 g/kg , makes the condition
optimum for heavy metal precipitation and rendered it inactive in sorption site of soil colloidal
system and prevent it to reach ground water table. However the little concentration of heavy
metal are varied from location to another to give an index that the pollution is sever and create
a toxin plume downward locations but not exceeded typical standards of WHO for drinking
water.
