Water pollution - Basic pollution parameters - Water quality indexes.Abstract
The research is summarized in conducting an experimental and analytical study that allows to determine the water quality of some small surface dams in Lattakia, namely: Al-Qanjara, Karsana, and Khirbet Al-Jouzieh dams. Hence the main objective of the research is to assess of water quality of the lakes of these dams , in order to know the possibility of adopting these lakes as sources of drinking water for the surrounding villages.
The research included brief information about the study sites of the three dams, in addition to a detailed explanation of a number of quality indicators, especially the two quality indicators: ( NSFWQI ) and ( NEWWQI ), which were later used to assess the water quality in the studied dam lakes.
The research methodology was then presented, which included the method of picking up the water samples required for testing, and then determining the values of the basic pollution indicators needed to calculate the values of the two quality indicators mentioned above.
The results of the quarterly tests were presented in a special table and then we represented these results graphically. This allowed us to discuss these results and analyze the possible reasons for their values fluctuating from one season to another in the three lakes.
Using the (NSFWQI) and (NEWWQI) indexes an assessment of the quality of the water of the studied dam lakes was reached, as it was found to be medium or low quality, and in both cases the water is not suitable for drinking in its current state, and protection measures for these lakes must be taken, in addition it's necessary to expose the water taken from these lakes for different purposes to treatment that lead to a decrease in the values of many pollution parameters, especially the Organic Pollution (BOD5) and bacterial pollution (FC) due to their direct negative impact on human health.
Finally, the conclusions reached through careful reading of the results of the tests, which allowed us to come up with a number of recommendations that must be followed to protect the lakes of dams studied from pollution.
