Abstract
Water pollution is a worldwide problem and world community is dealing the worst results of polluted water. The current study focuses on the pollution of water in the district of Jhal Magsi. Physicochemical parameters, heavy metal, microbial and pesticides were evaluated to assess the water pollution level. Physiochemical parameters pH, Electro conductivity, dissolved oxygen, total dissolved solids and turbidity, were analyzed by using standard methods. Heavy metal concentrations were determined by using a flame atomic absorption spectrophotometer, identification of bacteria was performed by Polymerase Chain Reaction, and pesticides were deducted by gas chromatography. Electric conductivity, dissolved oxygen, and turbidity ranges were found to be higher than WHO recommended limits with percentages of 63.11, 59.55, and 42.23% respectively. The concentration of Pb, Cd, and Mn was found higher than WHO recommended limits in water samples with percentage of Pb (33.55%), Cd (33.22%) and Mn (16.02%). S. aureus (81), P. aeruginosa (102), and E. coli (105), were detected in 225 samples of water with percentages 28.12, 35.41 and 36.45% respectively. The pesticides concentrations were measured, DDT (16.34%), Cyanazine (15%), Chlorpyrifos (16.34%), Simazine (13.53%), Aldrin & Dieldrin (10.85%), Endrin (9.02%), Carbofuran (10.12%) and Trifluralin (8.78%). From the present research it is concluded that water reservoirs of Jhal Magsi district need continuous monitoring. Drinking water contains high concentrations of heavy metals, pesticides, and bacteria which cause various diseases among people and water needs specially treatment then it should be usable for drinking purposes.
