An interactive map shows the results of the water tests after the release of Tribar hexchrome

EGLE Launches Informational Webpage to Keep the Public Informed

The Michigan Department of Environment, Great Lakes and Energy (EGLE) created a webpage, Michigan.gov/EGLETribarResponse, after Tribar Manufacturing in Wixom released an industrial plating solution in the system of the Huron River the weekend of July 29. The page includes an interactive map showing surface water sampling locations in response to the release, along with test results.

The plating solution contained hexavalent chromium, also called hexchrome, a known carcinogen that can cause adverse health effects through ingestion, skin contact or inhalation. The liquid was discharged into the sanitary sewer system and sent to the Wixom sewage treatment plant. Wastewater discharges into Norton Creek, which empties into the Huron River system.

Interactive map shows over 60% of ongoing sampling for hexchrome and total chromium over 42 miles of the Huron River system from Wixom downstream to Barton Pond, site of a water intake drinking water in the city of Ann Arbor. Location markers on the map expand to show details such as date, body of water, sample depth, and whether measurable amounts of hexachrome or total chromium were found. The map will be updated with the results of ongoing sampling and testing.

To date, of more than 150 surface water samples taken – including replicates for quality control – three had detectable levels of hexachrome., and all were below water quality values ​​to protect human health. One of the three detections was at the water quality value to protect aquatic life. The Michigan Department of Health and Human Services (MDHHS) today lifted an advisory that had been put in place to avoid contact with water from the Huron River system. State and local authorities continue to work together to protect public health, keep residents informed and answer questions. Resources for the public include:
