hexavalent chromium

The Michigan health department lifted its do-not-contact recommendation Friday evening after testing by environmental investigators found less than 20 pounds of carcinogenic hexavalent chromium likely made its way into Norton Creek from an accidental discharge by Tribar Technologies in Wixom. The state's initial estimate was more than 4,000 pounds.

State environmental regulators sent several violation notices to Tribar Manufacturing related to its unauthorized release of about 10,000 gallons of a hexavalent chromium solution into a sewer in Wixom. The carcinogenic chemical has been detected in a nearby pond and lake.

Two of the tests conducted in Hubbell Pond detected hexavalent chromium, a carcinogenic chemical. The testing was done after Tribar Manufacturing accidentally dumped 10,000 gallons of hexavalent chromium solution into the sewer system that's treated by the Wixom Wastewater Treatment Plant.

Last weekend, Tribar Technologies' Wixom plant discharged thousands of gallons of a liquid containing 5% hexavalent chromium into the city’s sanitary sewer.

"Several thousand gallons" of liquid containing hexavalent chromium have spilled into the Huron River. State regulators are urging people not to play in or drink from the river until further notice.
