Green algae, however (especially light-green hair algae), allows light and water to penetrate all the way down to the screen if the growth is kept less than 20 mm thick, [11] which allows the algae to grow faster and absorb more nutrients without dying and losing attachment to the screen. This is fortunate because green hair algae is the exact ...

The Camelford water pollution incident involved the accidental contamination of the drinking water supply to the town of Camelford, Cornwall, in July 1988. Twenty tonnes of aluminium sulphate was inadvertently added to the water supply, raising the concentration to 3,000 times the admissible level.
Water-borne diseases are also present as our drinking waters can be contaminated by cyanotoxins. If the HAB event results in a high enough concentration of algae the water may become discoloured or murky, varying in colour from purple to almost pink, normally being red or green. Not all algal blooms are dense enough to cause water discolouration.

A drinking water standard of 0.05 mg/L (equal to 50 parts per billion, or ppb) arsenic was originally established in the United States by the Public Health Service in 1942. After the passage of the Safe Drinking Water Act of 1974 (SDWA), the Environmental Protection Agency (EPA) was given the power to set the maximum contaminant levels (MCLs ...
