Waste Site Cleanup & Reuse in New England

Blue Stream Mystery Spill

Blue Stream Mystery Spill, Taunton, MA

On Nov. 12, 2011, EPA received a call from the Mass. Department of Environmental Protection in to investigate the source of blue discoloration in a waterway in Taunton that flows through an industrial and undeveloped area that includes a wetland. A private consultant working on a Brownfields site in the wetlands noticed the discoloration the week before and sample results indicated the presence of cyanide. There was no sign of discoloration in the Taunton River downstream.

A site inspection and conversations with Gallo Construction, which owns the property, led EPA to conclude it was coming from blue stained soils near a large salt pile operated by Gallo. EPA determined discoloration and cyanide came from sodium ferro-cyanide, an anti-caking agent used on salt. A strong blue color was visible for about 15 feet and a less apparent blue was observed up to 100 feet downstream. The sources sat about .3 river miles away from the Taunton River. The property owner agreed to hire a cleanup team to address the discoloration immediately. Gallo Construction agreed to do the clean-up, which was completed under DEP oversight.
