From the Associated Press:
The Southwest Michigan Land Conservancy has canceled an Earth Day program scheduled for Saturday after more than 600,000 gallons of raw sewage spilled into wetlands near the event's Kalamazoo-area location.
Conservancy workers discovered the leak Thursday and a cleanup was under way Friday. The Kalamazoo Gazette reports that vandals caused the spill by blocking a sewer line with several logs.
Sue Foune of Kalamazoo's Public Services Department says lime has been scattered to destroy bacteria. She says the wetlands will absorb and treat the sewage and there should be no long-term
But conservancy stewardship director Nate Fuller says nutrients in the sewage will boost invasive cattails that the group has been trying to remove.
The vandalism was reported to police.
