New economic model finds wetlands provide billions in filtration value
Southern Ontario wetlands provide $4.2 billion worth of sediment filtration and phosphorus removal services each year, keeping our drinking water sources clean and helping to mitigate harmful and nuisance algal blooms in our lakes and rivers.
A new study from the University of Waterloo uses economic valuation to help us understand the importance of Southern Ontario’s wetlands for water filtration – particularly as these sensitive ecosystems continue to be lost by conversion to agriculture or urban development.
