UPDATE: Analyst Confirm Oil Spill and Cause in Benzie County

Posted: Updated:

Questions finally being answered about an oil spill in Northern Michigan creek that has many concerned.

This is an update, the DEQ now confirms the oil spill we first told you about last night on 9&10 News at 5. The Department of Environmental Quality spent the day in Beulah assessing the spill in Cold Creek.

Someone discovered the oily sheen and reported it on Sunday.

Analysts looked into what could have caused the leak and finally have answers for some lingering questions.

The DEQ says a dredging company just started a project last week and was having some issues with equipment. "There's potential that the dredging operations hit some soil that has some oily product in it or perhaps some sort of container that had some oil in it," says Greg Goudy, DEQ analyst.

The dredging company installed some booms across Cold Creek to prevent the sheen from getting to the lake. The DEQ estimates one or two gallons of hydraulic fluid or diesel fuel leaked.

9&10's Katie Boomgaard and photojournalist Tony Zyber have continuing coverage on what caused the spill.
