Citizen science is the voluntary participation of the public in scientific research.
Through citizen science, people can contribute to monitoring and data collection programs to increase scientific knowledge about the world around us.
Algae Watch relies on citizen science to help our water quality experts identify and better understand cyanobacteria and algae blooms in B.C.
Health concerns with drinking or recreational water use
If you have health concerns related to drinking or recreational water use, please contact your local health authority.
