GLWA Statement on 1st Round of Testing Under New Michigan Lead and Copper Rule June 26, 2019

“Communities in Michigan are currently conducting their first round of testing using new sampling protocol adopted in Michigan’s revised Lead and Copper Rule; these results are due to the Michigan Department of Environment, Great Lakes and Energy (EGLE) beginning mid-July.  The new sampling protocol added an additional sample that will represent water that has remained static in lead service lines to homes for a minimum of 6 hours.  For many local systems, the results could mean higher lead and copper numbers than seen in prior sampling protocols.


It is important to note that GLWA continues to have water of unquestionable quality. As the provider of water treatment in southeast Michigan, GLWA remains committed to surpassing/overachieving all regulatory standards. Further, GLWA tests its water multiple times each day, significantly exceeding state/federal testing requirements.

As it relates to lead and copper, that means assuring that our Water Quality team is optimizing corrosion control throughout our regional system.  This optimization is achieved by adhering to corrosion control parameters established under an approved state corrosion control plan in our daily operations. GLWA has demonstrated continuous compliance with our State approved plan.”
