Until further notice, the Michigan Department of Health and Human Services is recommending that people and pets avoid contact with the Huron River water between North Wixom Road in Oakland County and Kensington Road in Livingston County. Hexavalent chromium is a known carcinogen that can cause a number of adverse health effects through ingestion, skin contact or inhalation.
The wastewater discharges to Norton Creek, which flows into the Huron River system. Liquid containing 5% hexavalent chromium was discharged to the sanitary sewer system from Tribar Manufacturing in Wixom last weekend and routed to the Wixom wastewater treatment facility. Investigators again stressed that more data is needed to develop a more complete picture of location, movement, and concentration of the contaminant. More than 30 samples were taken from varying depths from near the point of release downstream to Barton Pond in Ann Arbor.
The Hubbell Pond results were the only detections of hexavalent chromium from widespread sampling Thursday along the Huron River system downstream from the release. They were at and below the state’s values to protect aquatic life*. Two samples taken Thursday detected the chemical in Hubbell Pond. Two crews from the Michigan Department of Environment, Great Lakes, and Energy (EGLE) sampled waters upstream, downstream and within the pond Friday morning to gather more information about the potential location of hexavalent chromium, which was released from Tribar Manufacturing in Wixom last weekend.
– State investigators today focused on the Hubbell Pond area in Milford, where two test samples from yesterday showed a low-level presence of a toxic chemical released into the Huron River system by a manufacturing company.
