Decision Support Tool for the development of a setting-specific strategy from catchment to consumer against the occurrence of cyanotoxins in drinking-water

A decision support tool (DST) for the development of a system-specific strategy to avoid the occurrence of cyanotoxins in drinking water has been developed by the German Environment Agency (UBA). The DST is available on-line at the CYANOCENTER-UBA website.

This DST has been developed for:

  1. Water suppliers interested in assessing the cyanotoxin risk in their supply system.
  2. Public health authorities responsible for surveillance who suspect a cyanotoxin risk in water supply system(s) and/or via exposure activities, such as recreation.
  3. Environmental authorities planning a risk assessment or measures for water-body management and who are interested in a prognosis of the water-body’s reaction in relation to cyanobacterial proliferation.

“This DST is based on results from several projects on toxic cyanobacteria funded by the Ministry for Education and Science (Germany) and the European Union (e.g. PEPCY, NOSTOTOX, CYANOCOST) and has been developed during these projects by Verena Niesel, Jutta Fastner, Wolfgang Wenzel and Ingrid Chorus from the Federal Environmental Agency, Berlin. The support of Geoffrey Codd especially with the English version is gratefully acknowledged.” (From the CYANOCENTER-UBA website).
