Harmful algal blooms - Cyanobacteria

An algal bloom in 2014 resulted in an advisory against recreational use of JL Curran Reservoir, Cranston, RI
. ALgla bloom on JL Curran Reservoir

Cyanobacteria, also known as blue-green algae, can form harmful blooms in lakes, ponds, and rivers that make the water cloudy, sometimes even making the water look like pea soup or as if bright green paint has been spilled into the water. Under some circumstances these blooms may produce toxins that could make pets and people sick.

New study confirms that humans are responsible for increased cyanobacteria growth since 1800s...see http://www.fondriest.com/news/study-confirms-humans-responsible-for-increased-cyanobacteria-growth-since-1800s.htm for an overview.
