Hundreds of gallons of sewage sludge spilled out of the Fairfield wastewater treatment plant yesterday. About three-thousand gallons of sludge spilled on the ground when there was a malfunction in Fairfield’s wastewater treatment plant. Some of the sludge ran into a nearby storm sewer, and while about five-hundred gallons of sludge made it all the way to Cross Creek, state officials say there was no significant impact on the stream. Once the sludge leak was discovered, Fairfield city workers used sandbags to block the flow and then sucked up the sludge with a vacuum truck.
