The New York City Department of Environmental Protection (DEP) publishes a notice for residents of Lower Manhattan reassuring them that the DEP, in collaboration with other government agencies, is doing everything it can to protect public health. The agencies are taking samples of the air, dust, water, river sediments and drinking water and analyzing them for the presence of pollutants, the statement says, and comparing them to a variety of government “benchmarks, standards and guidelines.” The notice claims that current monitoring indicates that containment levels do not represent a significant threat to public health.
