Because salinity readings in freshwater will be significantly lower than in seawater or brackish water, readings are often expressed in mg/L instead of ppt (1 ppt = 1000 mg/L). Increased salinity levels have been observed in the lower reaches of the Colorado and Rio Grande rivers,

This will decrease the amount of waste product for disposal. On medium to large capacity plants, a chemical anti-scale treatment will improve recovery rates. This will

Chlorides in Fresh Water - University of Rhode Island
cels.uri.edubrackish (mixed salt and fresh) water are adapted to live with high chloride concentrations. Once chlorides are in a water body, there are no biological processes that remove them. They are not typically removed at water treatment plants due to restrictively high cost. Natural spikes in chloride concentration can occur during
CYANOBACTERIA (BLUE-GREEN ALGAE) BLOOMS When in …
www.cdc.govsingle-celled organisms live in fresh, brackish (combined salt and fresh water), and marine water. These organisms use sunlight to make their own food. In warm, nutrient-rich (high in phosphorus and nitrogen) environments, cyanobacteria can multiply quickly, creating blooms that spread across the water’s surface. The blooms might become visible.

Microcystis can vertically migrate, consume excess phosphorus at the sediment-water interface, and then rise to the water surface to form blooms (10). Careful simulta-neous control of both P and N is required in
