Kalamazoo River oil samples taken

MARSHALL, Mich. (AP) - Oil spill cleanup efforts are continuing on the Kalamazoo River.

A team was out on a recent morning sampling groundwater near Marshall.

Michigan Department of Environmental Quality biologist Mike Alexander says the sampling will be part of a lengthy investigative process that could last 24 to 30 months.

The Battle Creek Enquirer reports the investigation into the extent of remaining damage from the 2010 oil spill is one part of the work that will continue on the river this winter.

The DEQ also is working with Enbridge Inc., the company responsible for the spill, to eliminate contamination found along Talmadge Creek. Alexander says the work involves digging up and removing contaminated soil, then restoring the creek.
