CHATHAM, NJ - An accidental chemical discharge from Chatham's Washington Avenue School turned the water blue in Days Creek and prompted a call to the Chatham Fire Department and the County of Morris Hazardous Material team late Wednesday afternoon.

James Deacon, Supervisor and Environmental Health Specialist for the Morris County Hazardous Material Team, tested the water and declared it safe. The Chatham Borough Fire Department opened up water in the streets to wash away the blue water.

"It's a chemical that was discharged through a floor drain," Deacon said. "It was accidental. They didn't know that instead of going to the sewer treatment plant, it went into the waterway.

"We checked for petroleum products in the water. It was a ph (potential hydrogen) of 7, which is neutral. I think it was some kind of floor cleaner. It was a quick discharge. The ph is just like it would be in your pool." 

According to Steve Williams, fire coordinator for Chatham Borough, it was the fourth time this year that the county hazardous material team had been called to check out unusual water colors in the brook. Nothing dangerous has been found to date.

The Chatham Borough Fire Department supervised the flushing of water on Cherry Lane to clear out the blue water from Days Creek
