Online reports from WNEM and other news outlets have reported that recent tests of Caseville, Michigan’s water supply showed excessive levels of Trihalomethine. Trihalomethanes are formed as a by-product when chlorine is used to disinfect drinking water. Trihalomethanes forced the first water safety regulations to be issued after passage of the U.S. Safe Drinking Water Act in 1974.

Chemical Byproduct in Water System Seen in 2016 Testing

Caseville said they are seeing 2017 average test results at of Trihalomethine at 88 parts per billion.  Caseville’s 2016 Water Report showed measurements of Trihalomethine ranging from 40 to 100 parts per billion.  Four tests were conducted in 2016 with an overall average at 74 parts per billion. The safety standard is 80 parts per billion.

We spoke with Troy Hartz, Superintendent of the Caseville Water Plant. Caseville’s water supply comes from Saginaw Bay. He noted that the measurements in August have the highest level of Trihalomethine due to the warmer water from the lake. Hartz noted that the Michigan DEQ informed him that there are other Michigan water systems who draw surface water from lakes who are also experiencing the high Trihalomthine measurements during August testing. 

Water Quality Steps Being Taken 

The Michigan Department of Environmental Quality has been brought in to the Caseville Water Plant. The DEQ wants to determine the best way to address the problem and comply with the water safety standard. Hartz indicated that adjustments may be made of the amount of chlorine applied at Caseville’s pumping station to address the drinking water contamination.   

Caseville has not asked residents to seek other water sources but has asked residents with health concerns to consult with their doctor.

Long-term exposure to high levels of Trihalomethanes can lead to kidney or liver damage and an increased risk for cancer.

    I think it’s a sad day when beautiful pristine Caseville and lake Huron are being polluted. It is supposed to be a place of refuge, fresh air, and clean water. We have owned our lake home since we built it by hand in the 1950s. My parents and grandparents were ecologically and environmentally conscious way before recycling came into affect ie canning, gardening, recycling, repurposing, and making do with a modest home not some half million to a million dollar beach house. Plastics left over from people who don’t bother to pick up after their firework displays and beach trash lead to fish and wildlife ingesting them, and pollute our water. We should ban fireworks on Caseville beaches because quite a few people have ruined it for all of us.
