FOR RELEASE: WEDNESDAY, JULY 2, 1997
EPA today is issuing the second report to Congress on air toxics
falling into the Great Lakes, Lake Champlain, Chesapeake Bay and other
U.S. coastal waters.
The report confirms earlier findings that air toxics are a major
source of water pollution.
The report finds that persistent and bioaccumulative toxic
pollutants adversely affect environmental conditions in water
bodies(bioaccumulative pollutants are those that increase in
concentrations through the food chain, as larger organisms eat smaller
ones). In the Great Lakes states, for example, air pollution has been
one of the factors which have caused many states to issue fish
advisories for PCBs, mercury and dioxins.
The report reinforces earlier findings that the deposition of
airborne nitrogen dioxide is a significant contributor to water
pollution problems in the Chesapeake Bay. In fact, atmospheric
deposition is responsible for an estimated 27 percent of the annual
nitrogen concentrations in the Bay, compared with 23 percent for water
discharges from industries and other so-called "point sources." This
nitrogen in the Bay can result in excessive algal growth, known as
eutrophication; this, in turn, can contribute to reduced oxygen levels
in the water, causing harm to fish and shell fish.
The Clean Air Act Amendments of 1990 require a biennial
report to assess the contribution of atmospheric deposition to water
bodies, the environmental and public health effects caused by the
deposited pollutants, the sources of these pollutants, and the water
quality standards violations that may have resulted from deposition of
Copies of the report, entitled "Deposition of Air Pollutants to
the Great Waters,Second Report to Congress"(EPA-453/R-97-011,June
1997), will be available through EPA's Air and Radiation Docket and
Information Center (Docket Number A-97-21). The docket can be reached
via telephone at (202) 260-7548 or via facsimile at (202) 260-4400. A
reasonable fee may be charged for copying.
The report will be available soon on the Worldwide Web at:
