Drinking water samples from more than three dozen homes in Ann Arbor and Scio Township will be tested for 1,4 dioxane.
Well water samples will be sent to a laboratory in Lansing for testing. Environmental analyst Jennifer Conn works for the Washtenaw County Health Department. She is filling vials with water from an outside faucet at a home in Scio Township.
“We're trying to double back and hit the houses we weren't able to get samples from yesterday," she explains. "They [MDEQ] sends us vials. We fill them up and then overnight mail them to the laboratory in Lansing.”
Contamination from the Gelman dioxane plume is a threat to residents in the area west of Ann Arbor, near M-14. Conn says the tests are a precautionary measure, but homeowners she’s spoken with are concerned about the extent of the carcinogenic chemical. “They’re wondering who's being monitored, how close they are to the [dioxane] plume, and how they [could] be exposed."
Lab results will take about four to six weeks. Conn says additional homes near the plume may have their well water tested in the coming months.
