Abstract

Eutrophication is the process by which a water body becomes increasingly rich in aquatic plant life such as algae and aquatic macrophytes (water weeds). Eutrophication is characterized by the presence of sufficient plankton, algae, and water weeds, which cause water quality impairments for domestic water supply such as tastes and odors, shortened filter runs, THM precursor’s formation. Lakes are often classified according to their trophy or degree of enrichment with nutrients and organic matter. They are classified by their trophic state with the main classes of oligotrophic, mesotrophic, eutrophic, and dystrophic. The main cause of eutrophication is the large input of nutrients to a water body and the main effect is the imbalance in the food web that results in high levels of phytoplankton microalgae, with a silicon skeleton (diatom) biomass in stratified water bodies which can lead to algal blooms. King Abdullah Canal is the main surface water source of potable and agricultural water supply in Jordan. Two main problems seem to face the use of KAC for domestic and agricultural purposes. These problems are eutrophication and formation of chlorinated hydrocarbons during water treatment. Both problems develop as direct or indirect results of anthropogenic activities.
