Abstract

     In this study, the focus was on the contamination of groundwater with heavy chemicals in the area around the Zawiya Oil Refinery, and the impact of this pollution on water quality for various uses such as drinking and agricultural irrigation.

(27) samples were taken from (9) wells in the study area, and the samples were kept inside sterile plastic containers, and a sign was placed on each container, on which the number of the well to be examined was written, as the depths of the wells ranged between 23 and 75 meters. A set of chemical analyses (tests) were performed using a spectrophotometer to estimate iron and a Titration device Karl Fischer To estimate calcium and magnesium and compare them with local and international standard specifications. The results showed that the amount of iron in all wells exceeded the permissible limit according to the Libyan standards, amounting to  (0.68ppm - 0.35ppm), as well as the amount of calcium in all wells above the permissible limit according to the Libyan standards, where it reached (249.3ppm - 210ppm), as well as the amount of magnesium in all wells above the permissible limit according to the Libyan standard specifications, which reached (290 ppm - 157.4 ppm).
