Abstract
In Galicia there are supplies that collect water from reservoirs showing growth of cyanobacteria that could produce toxins. The drinking water treatment plants (DWTPs) of these supplies should provide adequate treatment and be subjected to maintenance. WHO guidelines make recommendations on the most suitable treatments for removing microcystins. The Department of Health developed a protocol of action against these events jointly with water basin authorities. 4 reservoirs and five treatment plants were identified for this study. The treatments of the plants, the maintenance carried out at the DWTPs and the results for sestonic and dissolved toxins analyzed by the Public Health Laboratory of Galicia in the reservoirs near the point of collection, before the treatment plants and after them, during the 2013-2014 biennium were evaluated.
