| Summary: | King Talal Dam (KTD) reservoir, Jordan's largest surface reservoir, is threatened by the activities
of the catchment’s area, both domes tic and industrial, which emit untreated was te into the reservoir’s
tributaries , consequently, raising the pollution and co n t aminating the water chemically and biologically.
Therefore , the objective of this study was to assess the water quality and the pollution load to the
reservoir in terms of some cardinal water quality parameters. Water samples obtained from inside and
release outlet site of the dam were chemically tested by a n analyzing the presence of heavy metals,
phenolic compounds, trace elements using as a screening tool ICP-MS, GCMS, and other equipment
for phys ico-chemical and other parameters. For the biological screening, eosine methylene blue (EMB)
media was used to investigate the presence of the fecal coliform and E. coli. Results obtained from
this study showed that the concentration of analyzed metals (Cu, Zn, Cd, Cr, Fe, Hg, Pb, Mo and
Mn) and other parameters (pH, EC, TDS, BOD, turbidity) are within the recommended standard limits
for these contents in irrigation water. Also, results obtained from this study indicates the pollution
tendencies of the surface waters of KTD reservoir, attributable to high levels of organic compounds ..
Results revealed significant toxicity of phenolic compounds was found in water samples, indicating the
water quality of these sample s is not potable. It is mainly due to the present of biological
contamination. The maximum concentrations of phenol was (2.09 mg l-1) and (1.82 mg l-1) for outlet
and inside water samples respectively. Among the selected phenolic compounds , the mos t frequently
detected we re cyclohexane and benzene, which was found to be present in all sampling sites. All the
analyzed samples of fecal coliform showed contaminated status ranging between 1.1 ´ 103 to 2.1 ´ 106
CFU 100 ml-1 from water and sewage samples respectively. E. coli counts were more than 1.1 ´ 102
CFU in 100 ml-1 in all samples which indicates that our irrigation water have biological pollution
which is very alarming. This study provides a very useful amount of information for detecting potential
toxicity risks . |
