CLINTON TOWNSHIP, MI — Macomb County officials said Monday a creek that turned green in Canton Township was not toxic.

Officials said the water in Cranberry Creek, which is located near 17 Mile and Garfield roads inside the Cranberry Subdivision turned into a florescent green color over the weekend was caused by a non-toxic dye that was used to check for illicit sewage connections and discharges, according to a news release.

"The township was doing dye testing because they had thought there might be an illegal sanitary sewer connection, which they fortunately found out was not the case," Public Works Commissioner Candice S. Miller said. "They didn’t dilute the dye enough and some people thought it looked like the Chicago River, it was so green. It’s non-toxic and doesn’t hurt humans or animals."
