New Haven Environmental Justice Network’s (NHEJN) goal is to safeguard the health of New Haven residents and reduce illness from environmental pollution. When the Greater New Haven Regional Water Pollution Control Authority (GNHWPCA) was created in 2005, NHEJN got environmental safeguards incorporated into the agreement. The New Haven Board of Aldermen unanimously passed a non-binding resolution calling for the new sewer authority to stop importing sludge and to find alternatives to sludge incineration in New Haven.
Synagro, Inc. operates and maintains the sludge incinerator under contract from GNHWPCA. They truck 18 tons (12 semi truck loads) of sludge a day from other communities in CT to incinerate in New Haven.
Sludge contains hazardous chemicals coming from flame retardants, personal care products, herbicides, pesticides, cleaning products, hospital waste and drugs. Sludge incineration releases mercury and other heavy metals, sulfuric and hydrochloric acid, volatile organic compounds including benzene, and radionuclides into our air and water. New Haven’s inner harbor is very contaminated with heavy metals; based upon recent core sampling 92 % of the inner harbor sediment contains toxic levels of mercury for plants and animals that live there. How many of us have seen residents fishing and crabbing in these waters?
The incinerator is old technology; it is dangerously close to residential homes; pollutants such as liquid mercury and benzene rain down on homes within ½ mile radius of the incinerator. Mercury in the soil is 70 times more toxic than lead according to the EPA.
Why are we doing this? Bridgeport is currently looking at building an anaerobic digester and GNHWPCA should be doing the same. GNHPWCA plans to decide this year whether to renew the contract for outside sludge incineration. These hazardous chemicals cause cancer, birth defects, illness and pollute our environment.
