SRSW & CARD are still waiting for the full sampling data to be shared

It may be several weeks before the data is included in the state's Gelman database.

Scio Sampling-sets 1-2

4 More Dioxane Hits on Scio Wells (set 2 - Nov) 12/15/2021

Scio Township's November sampling (set 2) found dioxane 0.25-1.0 ppb in 4 of 15 homeowner wells tested using the latest EPA 522 method as shown in slides above.

2 New Dioxane Hits on Scio Wells (set 1 - Sept-Oct)

Scio Township's own recent sampling [updated] revealed found dioxane just below 1 ppb (0.8 ppb) in a couple of residential wells by using the newer EPA 522 method. One of these wells is ~3/4 mile north of Gelman's 2021 7.2 ppb northern plume boundary and ~2/3 mile north of Gelman's northernmost monitoring well with detectable dioxane. Both new hits are beyond the 1000 feet range from previous hits where EGLE/WCHD periodically samples homeowner wells for dioxane.

Sampling for dioxane at less than 1 ppb gives us a heads-up on where the dioxane problems are to better address them.

Additional sampling is planned to guide cleanup efforts.

Gelman Site in Urbanized Area

The Gelman/Pall/Danaher site is unique in the amount of dioxane in the groundwater moving in several directions within an increasingly urbanized area with so many homeowner wells as their sole source of water
