DDT present in Michigan small town after nearly half a century; adverse health impact on community.

ddt1The Velsicol Chemical Corporation manufactured pesticides in a community in central Michigan and the town until 1963. DDT has a cumulative effect and is known for accumulating in food webs and persisting for decades in and river sediment and in the U.S. in 1972. A number of studies have have linked DDT exposure to effects on fertility, immunity, hormones and . Fetuses and young children are most vulnerable to DDT and the major concern is in the womb.

A battle to clean up the contaminated area has has led to a multi-million dollar clean-up effort by (EPA) and the Michigan Department of Environmental Quality (DEQ), and MIEPA took control of the Velsicol plant as a Superfund site in 1982. In 2006, DEQ sampled yards in a nine-block area near the plant after complaints from residents.

Upon finding DDT in the , orange fences were installed around heavily contaminated areas. Six years later the EPA cleaned up those yards, but further sampling found that nearly the entire neighborhood needed remediation. While four of those yards have DDT in excess of limits, one has excess polybrominated biphenyls, or PBBs, a Velisocol also manufactured and, in 1973, infamously mixed up with a cattle feed supplement, which led to widespread in Michigan.

Thousands of cattle and other livestock were poisoned, about 500 farms were quarantined and people across Michigan were exposed to the chemical linked to cancer, reproduction problems and endocrine disruption.

“Let’s say your backyard has DDT in it. If wind blows, and kicks up dust, you might [be exposed to] DDT. The sun shines, water evaporates, you might get a little DDT,” explains Dr. David Carpenter. “And who knows what other chemical exposure they’re getting from the site.”

In 2014, EPA contractors excavated contaminated from 59 yards in the town of 7,000 people, and this summer they will tear up 47 more yards, 10 city-owned properties, the athletic fields at the local high school, and replace St. Louis’ entire water system by tapping into a nearby community’s pipes.

Researchers have also determined that female mice exposed as a fetus were more likely to have diabetes and obesity later in life and causes epigenetic metabolic changes over multiple generations.
