STATE
COALITION FOR
REMEDIATION OF
DRYCLEANERS
WEBSITE RESOURCES
The State Coalition for Remediation of Drycleaners
(SCRD) prepared this brochure to explain some of
the health and environmental concerns associated
with contaminated drycleaner sites and to provide
an overview of the many resources available on
their website. Many of these resources may be
useful to state regulators, assessment and cleanup
contractors, drycleaner owners and operators, other
industry professionals, and community members.

About SCRD
SCRD was formed in 1998 as
a coordinating body for state
government regulators involved
in administering drycleaner
assessment and cleanup
programs. Since then, SCRD has
worked to increase collaboration
among states with established
drycleaner cleanup programs
and improve the effectiveness
of cleanups at contaminated
drycleaner sites. SCRD's primary
objectives are to:
*• Provide a forum for exchanging information and discussing the
best ways to implement and run state drycleaner programs;
> Share information and lessons learned with those states that do
not have drycleaner-specific programs; and
> Encourage the use of new technologies when cleaning up
contamination at drycleaner sites.
SCRD members come from 13 states-Alabama, Connecticut, Florida,
Illinois, Kansas, Minnesota, Missouri, North Carolina, Oregon, South
Carolina, Tennessee, Texas, and Wisconsin-that have enacted formal
drycleaner remediation programs. While these programs vary, they
generally require fees paid by drycleaners or solvent suppliers,
registration or licensing of drycleaners, compliance with applicable
federal and state laws, and implementation of pollution prevention
measures. In addition, seven states without official drycleaner programs-
Alaska, California, Delaware, Maryland, New York, New Jersey,
and Virginia-have taken a proactive role in addressing contaminated
drycleaners and actively participate in SCRD as Associate Member
States.
Since its inception, SCRD's work has been supported by the U.S.
Environmental Protection Agency's Technology Innovation and Field
Services Division.
The Problem
There are approximately 36,000 active drycleaning facilities in the United
States, and an estimated 75% of them are potentially contaminated.
This includes commercial, industrial, and coin-operated facilities where
soil and groundwater have been contaminated by chemicals used
to clean fabrics (also known as drycleaning solvents). In addition,
an unknown number of former drycleaning sites are contaminated.
-------
Because a majority of drycleaning facilities are located in urban areas,
contamination from chemicals used in drycleaning has impacted a large
number of public water supply wells and threatens many others.
Contamination from drycleaners often is the result of past industry-
accepted practices rather than the typical spill or release common with
other types of contaminated sites. Historically, many drycleaners
disposed of wastes containing solvents by pouring wastewater into
sanitary sewers, septic tanks, storm sewers, and floor drains; throwing
spent filters and sludge into the trash; or dumping wastewater on the
ground outside their facilities. In addition to contamination associated
with waste disposal, solvents have been released to the environment
during solvent delivery, transfer, and storage and through drycleaning
equipment operation and maintenance.
Cleaning up contaminated soil and groundwater at active and inactive
drycleaner sites is an issue facing state governments and drycleaners,
alike. Cleanup is especially critical in areas where groundwater serves
as the primary drinking water source. In addition, the migration of vapors
from these solvents into indoor air of homes and buildings from underlying
soil and groundwater contamination is a concern.
Perchloroethylene, or "perc" (also known as tetrachloroethylene or
PCE), remains the most widely used drycleaning solvent in the United
States. Perc is a dense, nonaqueous phase liquid and is heavier than
water. As such, it can penetrate concrete and can sink underneath
buildings through floor cracks. Perc is a listed hazardous substance and
is classified as a pollutant in both air and water regulations. It may pose
serious health hazards if exposure is not property controlled.
More environmentally friendly types of solyetits, such as carbon dioxide
and silicon-based solvent, have been,jntroduced in recent years.
Resources Available on SCRD's Website
On SCRD's website, you'll find information directly related to
addressing contamination at drycleaners, along with information
about how each member state administers its drycleaner
cleanup program.
SCRD Newsletter
Twice a year, SCRD produces a newsletter to announce recent events
and activities. Typically, the newsletter includes:
^- An overview of new publications relating to cleaning up drycleaners;
>• A summary of the most recent SCRD annual meeting;
-------
> Brief updates on each state's drycleaning program;
> Statistics documenting progress made at drycleaning sites in all
member states;
>• A list of remedial technologies being used at drycleaner sites; and
> A list of upcoming conferences, meetings, or events of interest to
SCRD members.
If you would like to be placed on the subscription list for the SCRD
newsletter, please visit www.drvcleancoalition.org/newsletter.cfm.
Copies of previous newsletters can be viewed on the SCRD website at
www. drycieancoalition. org/pubs. cfm.
Meeting and Conference Call Summaries
Summaries of SCRD annual meetings and conference calls are regularly
posted to the SCRD website. Meeting summaries include overviews of
both technical and administrative topics, along with links to presentation
materials. SCRD conference calls are held approximately every eight
weeks. Past meeting summaries can be found at www.drydearKoalition.ora/
members.cfm#meet, and past conference call summaries are available at
www.drvcleancnalition.orv/members.tfm#cc
Upcoming Conferences and Courses
A list of upcoming conferences, courses, and other meetings of interest
to drycleaners, regulators, assessment and remediation contractors, and
other industry professionals is available at www.drYdeancoalition.ora/
courses.cfm.
Publications
Several publications about the chemicals used
to clean fabrics, how states administer their
drycleaner programs, and the technologies used
to assess and clean up sites are available on
the SCRD website at www. drycieancoalition.
orq/pubs.cfin. Examples of recent publications
include:
Conducting Contamination Assessment
Work at Drycleaning Sites
SCRD prepared this report in fall 2010 to provide helpful information
for states and others involved in conducting site characterization
work at drycleaning facilities. It includes background information on
drycleaning operations, planning and conducting site assessment and
characterization, and a range of assessment technologies. The report can
be downloaded at www.drvdeancoalition.org/download/assessmentpdf.
-------
Comparison of Remedial Systems Employed at Drycleaner Sites
SCRD compared data from over one hundred drycleaning site remediation
projects across the United States to evaluate the various remedial
technologies and assessment techniques used at chlorinated and
petroleum solvent sites. The analysis can be downloaded at
www.drvcleancoalition.orci/download/site profile paper.pdf.
Drycleaner Site Profiles
Perhaps one of the most useful sources of information about cleanup
technologies being used to address contamination at drycleaner
sites is the drycleaner site profiles section of the SCRD website
(www.drydeancoalition.org/profiles). These profiles provide details about
cleanup systems that have been installed and operating for at least one
year at drycleaner sites in the United States and in other countries.
Each profile includes the site name, location, description, hydrology, type
and level of contamination, remediation technology used, results achieved,
costs, lessons learned, and point-of-contact for further information. A
search engine allows users to enter key words and search all profiles at
the same time. There currently are approximately 175 profiles that can be
found on the SCRD website. Industry professionals are welcome to add site
profiles to the database at any time. A guide to submitting profiles can be
found at www.drvcleancoalition.orct/Drofiles/profiles quide.pdf.
Chemicals Used in Drycleaning Operations
This viewable, downloadable
document and searchable,
on-line database is intended to
provide those engaged in the
assessment and cleanup of
contaminated drycleaner sites
with information on drycleaner
chemicals. The data also may be
of use to regulators conducting
compliance inspections at
drycleaning facilities. The
document provides current and
historical information on the
types of drycleaning solvents,
equipment maintenance materials, pre-cleaning/spotting agents, garment
treatments, and other drycleaning chemicals. The database can be found
at www.drvdeancoaliQon.orq/chemicals/Selectlnfo.cfm and the document
