Abstract:
It is crucial to monitor groundwater to ensure the sustainable supply of good quality water. The quality of water in Lebanon has been a major concern in recent years due to a range of factors including pollution, water scarcity, and aging infrastructure. Since collecting samples and laboratory analysis can be costly, and since karsts are dynamic environments that require more frequent measurements, we came up with adequate monitoring systems. These monitoring systems can help infer the degree of contamination through measuring indicator parameters in the targeted water system (such as turbidity, electrical conductivity, temperature …). The study area comprises the catchment area of El Kalb River which drains into four springs: Assal, Laban, Qachqouch and Jeita. This work provides the set-up of the needed monitoring systems, the way to read and interpret the data, come up with early warning systems, and how to mitigate contamination. Contents:
