Proving the Removal of Microcystins from Drinking Water

Cyanotoxins are a large group of chemical contaminants, including microcystins, cylindrospermopsin, anatoxin A and others, which are formed by cyanobacteria. Under certain conditions, the cyanobacteria can grow exponentially in water and may begin to release cyanotoxins from ruptured cells forming harmful algal blooms (HAB). An HAB present in lakes or rivers used as source water for municipalities pose a risk that toxic cyanotoxin concentrations may not be removed adequately by the water treatment facility systems.

NSF International published Protocol P477 to establish requirements for consumer treatment systems designed to reduce microcystins in public drinking water. Quantitative analysis of Microcystin RR, YR, LR, LA, LY, and LF is performed using on-line solid phase extraction in combination with liquid chromatography tandem mass spectrometry.  Application of devices meeting Protocol P477 requirements for the supplemental treatment of residential drinking water will provide substantial protection to the public water supply user.
