There have been few studies in Lebanon on the water quality of rivers; however most concentrated on water contaminants and did not address the issue of sediments and riverbed sediments. Further, very few studies relied on long-term water quality monitoring of rivers. Thus their conclusions were based on instantaneous assessments of water quality data only. The primary objective of the study is to assess the health of perennial rivers in Lebanon through the analysis of their riverbed sediments. This assessment will be used to aid in identifying the various sources of pollution in watersheds of sampled rivers. The main pollutants targeted for analysis are nutrients (nitrates and phosphates), heavy metals, and commonly used pesticides as these are typically correlated with effluent discharges from domestic sewage, industry, and agriculture.
