CHANGE IN TOTAL DISSOLVED SALTS AND CHLORIDES OF GROUNDWATER IN SEVERAL AREAS OF THE CITY OF ZLITEN

Abstract

Many studies were done on the main resource of groundwater in Zliten, which are consumed by different activities such as agricultural, industrial and service activities. In this study, the change in some characteristics of groundwater during the period from (2015 to 2021) were examined. The samples were collected from different (8) wells distributed over the study area. The first test was done in 2018 and the second test was done after three years in (2021). The results of both years are compared with the previous study in (2015). All samples were analyzed for the total dissolved salts (TDS) and chlorides, the results highlighted that the amounts of TDS and chlorides were exceeded the permissible limits according to the Libyan standard specifications and their concentrations were between (1178 - 6131) mg / liter, and (349 - 2475) mg / liter of the total dissolved salts and chlorides, respectively. Whereas the pH was Within the Libyan standard specifications rang.
