U.S., Canada to update Great Lakes water agreement

NIAGARA FALLS, Ontario (AP) — The United States and Canada say they will update a key agreement to protect the Great Lakes from invasive species, climate change and other established and emerging threats to the world’s biggest surface freshwater system.

Secretary of State Hillary Rodham Clinton said Saturday that the Great Lakes Water Quality Agreement, which was last amended in 1987, is no longer sufficient.

She announced the deal to revise it — something environmental groups have been pushing for — with Canadian Foreign Affairs Minister Lawrence Cannon during a ceremony marking the 100th anniversary of the Boundary Waters Treaty of 1909. The treaty created an international commission to settle water-related disputes between the two countries.

“It’s crucial that we honor the terms of the Great Lakes agreement as it stands today,” Clinton said on the international Rainbow Bridge with Niagara Falls as a backdrop. “But we also have to update it to reflect new knowledge, new technology and, unfortunately, new threats.”

The agreement commits the United States and Canada to restore and maintain the chemical, physical and biological integrity of the Great Lakes Basin ecosystem. Since the agreement was first signed in 1972, levels of polychlorinated biphenyls, mercury, dioxin and other pollutants have dropped and the lakes have seen the return of the bald eagle and other species.

But Great Lakes states and provinces have worried in recent years that the cleanup has lost momentum amid new threats from the growing population, new chemicals and climate change.
