According to the chemical pollution danger in general and its danger on groundwater
wells in agricultural areas particularly the inhabited ones , the scientific study was
implemented to determine the concentrations of some ions in water wells withi
n the area of
Hraesoon; In addition to, monitoring their changing values which indicate the rate of
chemical pollution in the study area due to existing activities.
The search involves a monthly periodic physical and chemical analyzes in the
invested wells in Hraesoon area , Banias city for a whole year. starting from September
2011 till August 2012 by choosing ten invested wells disterbuted in the area.
The study includes the changing of temperature ,pH, electrical conductivity, and the
group of negative ions (nitrate NO3
-, phosphate PO4
3-, sulphates SO4
2-, chloride Cl-) in
addition to positive ions (ammonium NH4 +, Sodium Na +).
The values of the studied ions have demonstrated a clear disparity in each month for
the samples taken from the same wells, due to the agricultural ,human activities and
climatic conditions that prevailed during the sampling dates.
The recorded results show cases of chemical contamination in the water wells
studied not identical the Syrian standard for drinking water (2011-2012) portend a lot of
health and environmental risks, especially that many of those wells are used for drinking
purposes.
The changes in coefficient of distribution of lead and cupper has been studied in
system with two phases, liquid water contaminated with lead and copper-solid (natural
Phosphate of Syria) correlation of the following factors: Time of mixing phases,
size of the
developed steel ,change the values of PH ,concentration of elemental lead and
concentration of element capper ,the concentration of calcium as a competitor to the
occupation of sites available on the solid phase, the ratio V\m presents the water phase size
on the mass of phase ,the Percentage removal of lead from aqueous samples prepared in
the laboratory91,57-99,95% were the best conditions for a vast proportion removed can be
summarized as follows:
PH=[6,63-10,11], Time of mixing phases =60 minutes and V/m=1000.
The Percentage removal of copper from aqueous samples prepared in the
laboratory 95,27 -99,96 % were the best conditions for a vast proportion removed can be
summarized as follows:
PH= [7,89-11,01] , Time of mixing phases =60 minutes and V/m=1000.
Ideal conditions have been applied that were obtained according to laboratory tests
on water samples from industrial input to Banias refinery and water samples from
industrial drainage to Syrian company for oil transport after Removal for lead was(
100%,99 %). Removal for copper was( 100%,98 %) .
