Dangerously high levels of benzene and naphthalene, both carcinogens, have been leaking into Baltimore harbor for the last eight years from an abandoned facility at the Sparrows Point steel mill, according to reports by the mill’s own environmental consultant. These reports were found in records examined by The Baltimore Brew under the Maryland Public Information Act.
State and federal regulators have been aware of this groundwater contamination since at least 2005, according to the records. But the Maryland Department of the Environment (MDE) only recently began to take steps to curb it. Actual containment of the pollution is many months, if not years, away from completion, MDE officials said.
Last February, federal officials expressed alarm at the amount of contaminants going into Baltimore harbor via the groundwater seepage. “In certain hot spots, the measured groundwater concentrations exceed 100,000 times the Maximum Contaminant Level for benzene and 1,000 times the MCL for naphthalene,” wrote Abraham Ferdas, an administrator at the Environmental Protection Agency (EPA).
Benzene, a highly flammable liquid in its natural state, was also found in harbor water that flows into the Chesapeake Bay, a particular cause for concern to EPA officials.
“The fact that benzene is measurable in the bay water is an indication that the pollutant loading rate from the Facility [Sparrows Point] is significant,” Ferdas wrote. “Typically, volatile organic compounds are rarely detectable in open water due to mixing, dilution and agitation of the large volume of receiving water.” Read the rest of this entry »
