INNOVATIVE RESEARCH FOR A SUSTAINABLE FUTURE

REGIONAL METHODS PROGRAM

The Regional Methods (RM) Program is an Office of Research and Development (ORD)
program administered by the Office of Science Policy that responds to high-priority, near-
term methods development needs of EPA Regions. RM projects focus on developing
methods necessary for the Regions to meet monitoring and enforcement objectives. Past
RM research projects have developed assessment protocols, biological and diagnostic
indicators, toxicity evaluation methods and improved sampling methodologies.

Goals of the RM Program

•	Provide near-term research (1-2 years) on high-priority, region-specific science
needs

•	Provide opportunities for ORD scientists to apply their expertise to regional issues
and explore new research challenges

•	Foster collaboration between EPA regions and ORD laboratories

•	Build a regional/ORD network for future scientific interaction

The Regional Science Liaisons (RSLs) manage the RM program within the Regions. They
engage ORD scientists early in project development to secure regional and ORD
management support and ensure that projects are within the scope of ORD's mission. RSLs
also play a role in preparation and delivery of RM project results to regional scientists and
managers.

Sample RM Projects

Collection of Pyrethroids in Water and Sediment Matrices: Development and Validation
of a Standard Operating Procedure- Region 9

Pyrethroid insecticides, which are highly
toxic to aquatic organisms, have become
the most commonly used class of
insecticides in agricultural and urban
marketplaces. They are often detected in
surface waters and sediments and
concentrations must be accurately
measured.

Pyrethroids tend to collect on the walls of
sampling vessels during sample collection
and storage. Loss of pyrethroids from the
sample onto these surfaces can invalidate
analytical and toxicity test results. The
tendency of pyrethroids to associate to
container walls depends upon the type of
sample collection device, container material
and other chemicals and organic matter in

the water. In addition, collection and transfer of samples
through multiple containers or pieces of equipment can
also increase the potential for pyrethroid loss.

Scientists from ORD/National Exposure Research
Laboratory (NERL), Region 9 and US Geological Survey
(USGS) collaborated to evaluate pyrethroid sample
containers and sampling methods and to develop sampling
procedures that minimize pyrethroid loss to walls and
tubing in sampling apparatus.

The results of this project were used to create standard
operating procedures (SOPs) for collecting water and
sediment samples that may contain pyrethroids. These
protocols are critical for accurate and consistent
measurement of pyrethroid concentrations, and for
assessment of potential effects on the environment.

Results were also used to prepare a USGS Scientific
Investigations Report that included new SOPs for
pyrethroid sampling . The SOP has been used by
wastewater treatment systems in Region 9 and nationwide
to study the fate of pyrethroids and by the State of
California for its general pesticide permit monitoring
program.

Keeping Beaches Safe—Region 5

Beaches are complex ecosystems where certain conditions
can sometimes lead to hazardous concentrations of
particular types of bacteria. Typically found in sewage,
these bacteria can multiply in the water and pose health
threats to swimmers.

When bacteria levels reach dangerous conditions, swim
advisories are issued and beaches are closed.
Unfortunately, water sampling and analysis can take over
24 hours, meaning an existing contamination might go
undetected until lab results are available.

In response to efforts to study issues associated with
pathogens and human health, EPA scientists in Region 5
and NRMRL. have developed a faster laboratory method to
test water for bacterial indicators. This method is called
quantitative polymerase chain reactions (qPCR), which can
cut the lab time needed down to only a few hours.

State and local officials in the Great Lakes region have
begun to use qPCR in tandem with Virtual Beach, a
software program developed by ORD to create models that
can predict contamination in real-time or even before the
contamination occurs. The ultimate goal is to use the
Virtual Beach model to predict bacteria exceedances, and
then confirm those results with qPCR, resulting in cost
savings and accurate and timely beach advisories.

Developing Monitoring Tools for Headwater
Intermittent Streams - Regions 1, 2, 3,4, 5,8, 9 & 10

Headwater streams lie at the aquatic-terrestrial interface
and represent much of the stream miles in the United
States. Little is understood about the consequences that
alteration and loss of headwater streams impose on larger
downstream water bodies. Because headwater streams

drain smaller areas
with less variable
types of land use
than larger water
bodies, they provide
a better assessment
of land use effects.
However,

of traditional

assessment methods. Understanding associations between
stream permanence and organisms living in the streams is
the first step in developing biocriteria for the most
abundant running waters in the nation.

Through this project, scientists at ORD/NERL collaborated
with scientists from several regions to develop field
protocols for assessing the hydrological permanence of
headwater streams. Several biological and physical
indicators were identified to distinguish ephemeral,
intermittent and perennial stream reaches. The results of
this RM project have gained interest from many states as
they work to understand the small area watershed drained
by headwater streams. The EPA Science Advisory Board has
recognized the collaborators with EPA's Scientific and
Technology Achievement Award for notably excellent
research, "Providing Science to Address the Jurisdictional
Determination of Headwater Streams under the Clean
Water Act"
