GOAL:

What we track: percentage of water supplies meeting treatment requirements

Prior to distribution to water customers, sources of drinking water are treated to ensure that high-quality water is delivered from treatment plants (which may be owned by local governmental authorities or private business enterprises). Blue Accounting’s Drinking Water issue is focused on water supplies serving the public, defined as community water supplies in the United States and municipal water supplies in Canada. There water supplies may rely on water sources from underground aquifers, surface water- including inland waters of the Great Lake basin and the Great Lakes, or a combination of groundwater and surface water.

Companion assessments conducted under the Great Lakes Water Quality Agreement more narrowly examine the population served by community water system that met all health-based standards for the U.S. and treated water sample results in compliance with water quality standards for Ontario.

Blue Accounting is examining health-based standard violations, along with acute health-based, monitoring and reporting, and public notification violations, providing a more-detailed picture of not only treated water quality, but the requirements that assure that state and provincial agencies, the federal government, and ultimately drinking water customers are informed of new or emerging issues with water treatment at the nearly ***** water supplies in the Great Lakes basin.

Why it matters

Nearly 40 million people get their drinking water from the Great Lakes.
