New details about Huron River chromium spill emerge from Michigan EGLE “egregious” violation notice issued to Tribar Technologies.

An employee at Tribar Technologies in Wixom overrode the company's waste treatment alarms 460 times in the span of nearly three hours on the night which state regulators believe a toxic chemical release to the Huron River initially began last weekend.

According to the EGLE notice, that's when a 14,923-gallon rinse waste tank holding about 10,000 gallons of "acid etch material" with about five percent total chromium was emptied into the Wixom wastewater system as a contamination slug, which overwhelmed the sewage plant.

 

Don't worry though, because this toxic and carcinogenic spill won't reach Ann Arbor for...two weeks.

There has been widespread concern over the potential for contaminants to reach the city of Ann Arbor's water intake downstream at Barton Pond, although computer modeling has shown that the slow-flowing river wouldn't likely bring any chromium to the city for several weeks.

 

Though it might sound like it's just the one employee's fault, the company culture likely has something to do with it since the same company contaminated water in the past with PFAS.
