Assessment of the quality of Surface and Groundwater in Shegagha area

Abstract

Water samples were collected from eleven surface and deep wells in the Shegagha area to study the concentration of salt ions and element ions, as well as the pH, EC, and TDS levels. The results indicate that the average carbonate ion concentration is 647.81 ppm, which exceeds the acceptable range for drinking water according to Libyan and WHO specifications in most samples. Additionally, the average chloride ion concentration is 966.73 ppm, exceeding the acceptable drinking water limits in most samples. The concentration of sulfate ions in all samples exceeds the recommended limits, with an average of 1054 ppm. On the other hand, the sodium ion concentration is within permissible limits, with an average of 73 ppm. The average potassium ion concentration is 3.345 ppm, meeting the standards for drinking water. The pH level averages at 7.045, within the permissible limits. However, the TDS and EC levels are high, with average concentrations of 1477.45 ppm and 1676 dsm- respectively, exceeding the acceptable limits for drinking water according to Libyan and WHO specifications.
