If you would like to look up 1,4-dioxane sampling results, there are a few options available.
The Michigan Department of Environment, Great Lakes and Energy (EGLE) maintains a database of sampling results. This database includes data for monitoring wells, surface water monitoring locations, and drinking water wells (for those properties that qualify for the state-funded program). The database, which is updated monthly, is in Microsoft Access, so you will need the Microsoft Office suite to view the database. Please visit EGLE's Gelman Sciences webpage and look under "What's New" to download the latest version of the database.
Once you have downloaded and opened the database, go to "View Sample Results/Well Information" where you will be able to search by well name. Please reference the plume map for well names.
Washtenaw County Historical Records
Another location to look for 1,4-dioxane sampling results is the Washtenaw County Permit Records program, OnBase. To use OnBase, search by street number only, then scroll through the results until you find records for the address you are looking for. This program has historical drinking water well records, including water quality sampling and drilling logs if available.
Ann Arbor's Municipal Water Testing Data
The City of Ann Arbor maintains a log of their monthly 1,4-dioxane testing. 1,4-dioxane is sampled for in the raw water sources (the Huron River at Barton Pond and the groundwater wells at Steere Farm) and also in the treated drinking water. To view the City's sampling data, visit their Water Treatment webpage, then view 1,4-Dioxane Water Testing Data under "Keeping Our Customers Informed: Dioxane".
