The Crystal Cleaners Site at 343 West Pulteney Street in
Corning has been reclassified and no longer presents a significant threat to
public health and/or the environment. According to the Department of
Environmental Conservation:Site RecordAdministrative
Information
Site Name: Crystal Cleaners
Program: State Superfund Program
Site Description
Site Name: Crystal Cleaners
Program: State Superfund Program
Site Description
Location: The Crystal Cleaners Site is located at 343 West
Pulteney Street in a mixed commercial and residential area near the western
boundary of the City of Corning, Steuben County. Site Features: The main site
feature is a one story vacant retail building that was the location of the
former dry cleaner, as well as a gas station and a Laundromat. Residential
properties are located to north, south and east of the Site with a commercial
property located to the west of the Site. Current Zoning/Use(s): The site is
currently inactive, and is zoned for commercial use. Historical Use(s): A dry
cleaner occupied this site from 1973 until 2007. This site has also been the
location of a gas station from the early 1970’s until 2008. Site Geology and Hydrogeology: The Site is
located in Cohocton/Chemung River Valley, which runs east-west.
Overburden soils at the Site consisted primarily of silts, sands and gravel.
The Chemung River is a local groundwater discharge area. Groundwater at the
site was encountered at approximately 10 to 12 feet below ground surface and
flows to the southeast towards the Chemung River.
Site Environmental Assessment
Remediation at the site is complete. Prior to remediation,
the primary contaminants of concern were tetrachloroethene (PCE) and its
associated daughter products. Remedial actions have successfully achieved soil
cleanup objectives for restricted residential use. Residual contamination in
the groundwater is being managed.
Site Health Assessment
People are not drinking contaminated groundwater because the
public water supply that draws water from this well field is treated before the
water is distributed to consumers. In addition, there are no known private
water wells in the area. Volatile organic compounds in the soil may move into
the soil vapor (air spaces within the soil), which in turn may move into
overlying buildings and affect the indoor air quality. This process, which is
similar to the movement of radon gas from the subsurface into the indoor air of
buildings, is referred to as soil vapor intrusion. Air sampling at one vacant
on-site and one off-site building has shown that the indoor air is being
affected by soil vapor intrusion. However, concentrations of site-related
contaminants in the indoor air of those buildings were within typical
background concentrations and did not exceed applicable guidelines. A sub-slab
depressurization system (a system that ventilates/removes air beneath the
building) has been installed at the off-site building to prevent the inhalation
of site-related contamination. In addition, impacts to soil vapor beneath an
off-site building were identified and continued monitoring of this structure is
recommended to verify mitigation actions are not needed.
