Sifting sediments for contaminant analysis.
USFWS/Pedro Ramirez, Jr. | | ".
. . synthetic pesticides have been so thoroughly distributed throughout the animate
and inanimate world that they occur virtually everywhere. They have been recovered
from most of the major river systems and even from streams of groundwater flowing
unseen through the earth. Residues of these chemicals linger in soil to which
they may have been applied a dozen years before. . . They have been found in fish
in remote mountain lakes, in earthworms burrowing in soil, in the eggs of birds--and
in man himself." -
Rachel Carson, Silent Spring |
Pollution is one
of the American public's greatest environmental concerns. Like the proverbial "canary
in the coal mine," fish
and wildlife often signal pollution problems that ultimately affect people
and their quality of life. The U.S. Fish and Wildlife
Service (Service) is the main federal agency dedicated to protecting wildlife
and their habitat from pollution's harmful effects, helping to create a healthy
world for all living things.
WHAT WE DO:
Contaminants Prevention. Contaminants specialists review environmental
documents, legislation, regulations, and permits and licenses with pollution
potential to ensure that harmful effects on fish, wildlife, and plants are
avoided or minimized. Some examples include:
- analysis of documents and permits related to control of nonpoint source
pollution from agriculture and urban runoff, point source pollution from
industrial and municipal waste treatment facilities, and discharges of dredge
and fill material;
- review of proposed Federal projects related to mining, agricultural irrigation,
range management, and oil and gas development to ensure that habitat quality
concerns are adequately addressed;
- review of EPA pesticide registration
proposals to ensure that potential impacts to fish and wildlife are considered;
and,
- review of pesticide use on FWS lands to ensure these chemicals are properly
applied and, in some cases, to recommend the use of acceptable alternatives.
Contaminants Identification and Assessment. Service environmental contaminant
specialists conduct field studies to determine sources of pollution, to investigate
pollution effects on fish and wildlife and their habitat, and to investigate
fish and wildlife die-offs. Sites typically assessed include those impacted
by pesticides, industrial wastes, oil and hazardous
waste spills, and drain water from agricultural irrigation and mining,
as well as Superfund sites and other sites
contaminated at some time in the past. Contaminants specialists have also developed
tools such as the Contaminants Assessment Process
(CAP), which was developed in cooperation with the US Geological Survey,
Biological Resources Division's Biomonitoring
of Environmental Status and Trends (BEST) Program, to assist in evaluating
contaminant threats to national wildlife refuges, as well as other Service
lands. In addition, field specialists conduct contaminant surveys prior to
the Service buying new lands.
Contaminant Cleanup and Resource Restoration. Data collected
in contaminant assessments is often used to secure compensation
for resources lost or degraded by hazardous waste releases or spills.
These efforts are part of the Natural
Resource Damage Assessment and Restoration Program (Restoration
Program). The Service also takes part, through contaminants
identification, assessment, planning and restoration, in the Department
of Interior's National Irrigation
Water Quality Program (NIWQP). Contaminant specialist are often
called in by the US Environmental
Protection Agency (EPA), US Coast
Guard, Department of Defense,
or various other Federal or State agencies responsible for cleaning
up a contaminated area, to ensure that fish and wildlife and their
habitat are adequately protected during, and upon completion of,
the cleanup. Contaminants specialists also work closely with National
Wildlife Refuge managers to design and implement actions to
cleanup oil and hazardous material on refuge lands.
Technical Support. Training field office staff, analyzing contaminant
samples, and managing information are all key to the Contaminants Program's
success. A large part of the Program's technical support comes from the Patuxent
Analytical Control Facility (PACF), part of Patuxent
Wildlife Research Center in Laurel, Maryland. Staff at PACF are responsible
for such things as overseeing all Service chemical analysis and managing the
Environmental Contaminants Data Management System. This system is designed
to electronically store, analyze, and create reports on the vast amount of
analytical information obtained from fish and wildlife tissue samples collected
by FWS biologists
