Examination of Some Chemical Properties of Well Water for Residential Units in Al-Jazira Region – Misrata

Abstract

Water is one of the most important natural resources on the planet and is a sure reason for economic progress and underdevelopment, and there is no doubt that the quality and safety of water plays an important and direct role in the health of the consumer. A study was conducted to determine the quality of the water of the wells in the Jazira area in the city of Misrata for the period from the beginning of October 2016 to the middle of July 2017, the study sample included 25 wells out of 36 i.e., 69.4% and the chemical tests were conducted (absorbed biooxygen, chemical oxygen consumed, ammonia, nitrate, nitrite, pH, alkalinity, total dissolved solids, chloride, total hardness, carbonates, bicarbonates, chlorine, and sulfates). The results of chemical tests showed that 4% of the well water is unusable, 12% of the water is good and usable, and 84% of the well water can be considered suspicious. Despite the proximity of the wells to the sewage network, there is no pollution of the well water with sewage water, and the results of the study showed that the main source of domestic water for about 50% of the region's population is the city water network and well water, and that nearly two-thirds of the families have been living in the area for more than 10 years, and the results of the study showed the limited or non-existent role of the supervisory and inspection authorities in the area. The study recommended the need to activate the regulatory authorities with optimal Libyan guidelines and uniform limits for drinking water.
