Groundwater Pollution and Wastewater Management in Derna City, Libya

摘要

The study attempts to analyze the groundwater contamination and the health impact resulting from overflowing and leaking of municipal wastewater Derna (North-East Libya). About 3% out of 14798 families living in the study area were used as a study sample and distributed to them questionnaire using the Stratified Relatively Sample and Chi-square was used to analyze the statistical data. The 26 water samples were taken and analyzed chemically and bacterially. The results showed that there are approximately 29% of residents used of septic tanks to disposal their wastewater and about 40.5% of them do not discharge their tanks. And this has led with sewage overflowing from net work to leakage of pollutants to aquifers and has changed the groundwater quality. The bacterial analysis showed the significant increase of E. coli in most of water source, beside the increase of chemical elements that exceeded the maximum limits of standards of drinking water. The problem has caused some diseases such as incidence of intestinal, dermatologist, chest diseases, poisoning, cirrhosis of the liver and kidney failure but about (81%) of these diseases are intestinal diseases.
