Illinois environmental officials are finishing cleanup at a Springfield park where motor oil leaked into a lagoon.
The Illinois Environmental Protection Agency and a cleanup contractor have removed plants in Washington Park and will take soil samples for analysis, state hazardous material specialist George Krebs said.
The lagoon was contaminated with used motor oil that leaked out of melted containers during a Sept. 8 fire at the Merlin auto shop on Wabash Avenue. More than 500 gallons of oil spilled into storm drains and a creek that runs into the lagoon.
There are no signs of the spill affecting aquatic animals or plants in the area, Krebs said.
