Information about dioxin levels in Saginaw township’s West Michigan park will not available until June, U.S. Environmental Protection Agency officials said today.
Last week the agency said that it will sample soil in the park to determine whether it has been contaminated by dioxin-laden sediments from the Tittabawassee River, which flooded the park late last month.
The Tittabawassee is contaminated with dioxin and other chemicals from Dow Chemical’s Midland facility.
In 2009 EPA ordered Dow to clean playground equipment in the park and remove more than 17,000 tons of contaminated soil after dioxin levels at 5,900 parts per trillion were measured. EPA requires cleanup at levels of 1,000 ppt and has proposed updating cleanup guidelines to require action at 72 ppt.
In presentations to local residents the agency has promised to take swift action to address dioxin exposure risks in high use areas.
Dioxin is a carcinogen and is known to cause health problems at extremely minute levels.
People who visit West Michigan Park are advised to avoid contact with the soil and to wash their hands with soap after visiting the park.
