The Michigan Department of Community Health says it has evaluated surface water in the area of the 2010 oil spill on the Kalamazoo River.
In a news release, the department says contact with chemicals through swimming, canoeing, or other recreational activities does not pose any risk of long-term harm. But it does say that contact with oil sheen or globules of oil may lead to skin irritation.
The state health department says testing on fish shows oil levels to be very low, and similar to fish caught upstream of the oil spill.
The Department of Community Health says the assessment was done on the stretch of the Kalamazoo River affected by a massive oil spill in 2010. Enbridge Energy continues to clean up from the spill which was caused by a rupture in one of its pipelines near Marshall.
