Governments of Canada and the United States Announce Phosphorus Reduction Targets of 40 percent to Improve Lake Erie Water Quality and Reduce Public Health Risk
New targets to reduce toxic and nuisance algae blooms affecting Lake Erie
WASHINGTON. DC – (RealEstateRama) — U.S. Environmental Protection Agency Administrator Gina McCarthy and Canada’s Environment and Climate Change Minister Catherine McKenna today announced that Canada and the U.S. have adopted targets to reduce phosphorus entering affected areas of Lake Erie by 40 percent. The targets announced today will minimize the extent of low oxygen “dead zones” in the central basin of Lake Erie; maintain algae growth at a level consistent with healthy aquatic ecosystems; and maintain algae biomass at levels that do not produce toxins that pose a threat to human or ecosystem health.

Through the Great Lakes Water Quality Agreement, Canada and the United States committed in 2012 to combat the growing threat of toxic and nuisance algae development in Lake Erie, and agreed to develop updated binational phosphorus reduction targets for Lake Erie by February 2016. The 40 percent reduction targets are based on 2008 loading levels. Canada and the United States have committed to develop domestic action plans, by no later than February 2018, to help meet the new targets.
“To protect public health, we must restore the Great Lakes for all those who depend on them,” said Gina McCarthy, Administrator, United States Environmental Protection Agency. “The first step in our urgent work together to protect Lake Erie from toxic algae, harmful algal blooms, and other effects of nutrient runoff, is to establish these important phosphorus limits. But, establishing these targets is not the end of our work together. We are already taking action to meet them.”
The Honourable Catherine McKenna, Minister of Environment and Climate Change said, “Canada recognizes the urgency and magnitude of the threat to Lake Erie water quality and ecosystem health posed by toxic and nuisance algal blooms. By establishing these targets, we strengthen our resolve to work with our American neighbours, and Canadian and U.S. stakeholders who share these waters, to protect the tremendous natural resource that is Lake Erie.”
Algae occur naturally in freshwater systems. They are essential to the aquatic food web and healthy ecosystems. However, too much algae, linked to high amounts of phosphorus, can lead to conditions that can harm human health and the environment. Since the 1990s, Lake Erie has seen an increase in algal growth that has compromised water quality and threatens the Lake Erie region’s recreation-intensive economy. The targets were developed after extensive public input from a diversity of sectors.
Quick Facts
• The 2015 harmful algal bloom in Lake Erie was recorded as the largest bloom this century.
• Modeling experts from the United States and Canada used nine different computer simulation models to correlate changes in phosphorus levels with levels of algal growth in order to determine phosphorus load reduction targets.
• A binational public consultation process was held between June 30 and August 31, 2015. Final targets were established following widespread support for the draft targets and the target setting process.
• More than 40 Canadian and American experts formed a binational team under the leadership of Environment and Climate Change Canada and the United States Environmental Protection Agency to develop the targets.
• In Canada, more than 50 individuals, groups and agencies representing Agricultural and other non-government organizations, Conservation Authorities, municipal governments, Ontario government agencies, First Nations, and Universities commented on the draft targets through an on-line tool and face-to-face discussions.
