LIMESTONE — Environmental officials are urging people to avoid contact with water in and around a northern Maine stream after more than 1 million gallons of untreated wastewater discharged from a busted sewer pipe.

The Department of Environmental Protection said today that a break in a 15-inch sewer line from the Loring Commerce Center to the Greater Limestone Utility District led to a discharge into Greenlaw Stream and surrounding wetlands.

Officials said the break likely occurred several weeks ago, but that the line is in a remote area and was only discovered Monday.

The DEP says levels of E. coli in the stream are nearly as high as those typically found in raw wastewater. The stream is popular this time of year for fishing and fiddlehead-picking.
