Trailer Village
Site History
Trailer Village Laundromat facility operated on the Trailer Village Park
property from 1960 to the late 1970s. During that time, a dry cleaning
solvent, PCE, was discharged improperly resulting in a release to the
environment. There is also evidence of potential spills occurring near an
underground storage tank that held PCE.
In 1991, the Washington Department of Health sampled drinking wells on the
property. PCE was detected above Federal Drinking Water Standards (FDWS)
and state cleanup standards. Private drinking wells on and around the
property were then also tested. PCE was also detected above the state and
federal standards in several of the private wells.
In addition, PCE was detected in one of the City of Centralia’s unused Public
Water Supply Wells. In 1994, homes on the Trailer Village Park property
were hooked up to the City of Centralia Water Supply and Sewer System.
In 1995, ten on-property septic tanks were cleaned and removed or closed.
PCE was detected above state standards in sludge samples taken from the tanks.
Additional deep soil and groundwater testing were recommended. Groundwater and
soil have been investigated several times since 1995 by Ecology, the Department
of Health, and the City of Centralia. These investigations helped to
determine where the levels of highest contamination were and which areas were in
need of cleanup.
The City of Centralia, from 2001-2005, switched 76 owners of privately-owned
domestic wells to the public water system. In 2005, a groundwater
treatment system was constructed by the City of Centralia to remove PCE from the
contaminated groundwater. The treatment system was installed as an interim
action (partial cleanup action). Groundwater has been monitored for PCE since
that time and results have shown that the treatment system is effectively
removing PCE.
In 2006, Ecology entered into an Agreed Order with Coluccio
Family LLC which required them to:
- Summarize and evaluate all data collected to date to determine if there
were any data gaps.
- Sample groundwater.
- Conduct a Remedial Investigation and Feasibility Study to determine
extent of contamination and evaluate and select possible cleanup options.
The Feasibility Study determined that the groundwater treatment system,
installed in 2005 as an interim action, is the final cleanup action for this
site.
CURRENT STATUS
Ecology and Coluccio Family LLC (CFLLC) are entering into a Consent Decree to
complete cleanup activities at the Trailer Village Park property at 1313
Harrison Avenue in Centralia. The Consent Decree (legal agreement) requires
groundwater monitoring to determine when contamination has been reduced below
state cleanup standards. In addition, an environmental covenant will be placed
on the property deed to protect people from small amounts of contamination that
remain on the site. Cleanup will be achieved when the levels of PCE in
groundwater are at or below state cleanup levels (as outlined by the Model
Toxics Control Act).
Ecology wants to keep you involved! A
Public Participation Plan has been
written to outline how Ecology will keep you informed and involved during the
investigation and cleanup. You will have the chance to review and comment on
key documents during the investigation process. Documents will be at this web
site and at the repository locations listed to the right as they become
available.
