General Information

Site Name and Location:		Camarota Cleaners Mechanicville, New York, United States
Description: Historical activity that resulted in contamination.		Dry cleaning operations were performed in a one story stand alone building. From 1970s to 1991, dry cleaning operations utilized PCE as the dry cleaning agent. The site is located within an urban residential area.

Contaminants:

Contaminants: Contaminants present and the highest amount detected in both soil and groundwater (please avoid giving ranges).		Contaminant Conc in GW Conc. in Soil 1,2-Dichloroethene 180 mg/L Tetrachloroethene (PCE) 130 mg/L Trichloroethene (TCE) 39 mg/L Vinyl Chloride 62 mg/L
Other Contaminants Present: Indicates what other contaminants were found on-site
Deepest Significant Groundwater Contamination:		7 ft bgs
Plume Size:

Site Hydrology:

Depth to Groundwater:		7 ft bgs
Lithology and Subsurface Geology:		Consists of 6 to 12 feet of silty sand with gravel overlying bedrock.
Conductivity:		0.002 ft/day
Gradient:		0.0174

Pathways and DNAPL Presence:

Pathways:		Groundwater Soil
DNAPL Presence:		No

Vapor Intrusion Pathway:

Has the potential for vapor intrusion (VI) been evaluated?		Yes
If the site has been evaluated, how was it evaluated?		Soil vapor and/or Sub-slab vapor sampling Indoor air sampling Groundwater sampling Compared sample concentration to screening criteria
Results of VI Evaluation:		A potential VI pathway has been indentified
Has a vapor mitigation system been installed?		Yes
Type of Vapor Mitigation System(s):		Sub-slab Depressurization

Remediation Scenario:

Cleanup Goals:		Protection of human health and the environment. Compliance with New York State standards, criteria, and guidance.
Remedy Level:		Interim Action

Technologies:

Technologies Used:		In Situ: Vapor Mitigation
Other technologies used:		Phytoremediation was performed by the property owner, but not included as part of the remedy.
Why the technology was selected:		Can achieve desired goals in a reasonable timeframe and was cost effective.
Date implemented:		March 2007
Final remediation design:

Lessons Learned:

Lessons Learned:

Trees found to be taking up PCE, but limited reduction in groundwater concentrations after two years. Groudwater up take rates will increase as the trees mature, which may reduce groundwater concentrations.
