General Information

Site Name and Location:		Fashion Cleaners Junction City, Kansas, United States
Description: Historical activity that resulted in contamination.		The site operated as a drycleaner from 1950 to 2006. The site is currently occupied by a used car dealership. Contamination was identified in the drains and along the sewer line exiting the building. The nearest receptor is a trailer park located adjacent to the facility. The investigation, assessment and remediation of the site were done with accordance with the Kansas Drycleaner Environmental Response Act.

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 cis-1,2-Dichloroethene 245 ug/L Tetrachloroethene (PCE) 66800 ug/L 6378 ug/Kg trans-1,2-Dichloroethene 110 ug/L Trichloroethene (TCE) 7990 ug/L
Other Contaminants Present: Indicates what other contaminants were found on-site
Deepest Significant Groundwater Contamination:		48 ft bgs
Plume Size:		1000 ft long x 500 ft wide x 20 ft deep

Site Hydrology:

Depth to Groundwater:		23-31 ft bgs
Lithology and Subsurface Geology:		Sand, silty sand and silty clay to bedrock at 42-53 ft bgs. Bedrock is interbedded limestone and shale.
Conductivity:		ft/day
Gradient:		0.002

Pathways and DNAPL Presence:

Pathways:		Groundwater Soil
DNAPL Presence:		No

Vapor Intrusion Pathway:

Has the potential for vapor intrusion (VI) been evaluated?		No
Has a vapor mitigation system been installed?		No

Remediation Scenario:

Cleanup Goals:		Below EPA Maximum contaminant levels for PCE and PCE degredation products in soil and groundwater.
Remedy Level:		Full Scale Remedy

Technologies:

Technologies Used:		In Situ: Soil Vapor Extraction
Other technologies used:
Why the technology was selected:		SVE was selected based on known efficiency in the site geology and cost. A remediation trailer was used from another site.
Date implemented:		Well installation September 2008, system start-up November 2008.
Final remediation design:		Three vertical SVE wells to 25 ft bgs with approximately 15 ft of screen. Three monitoring wells to determine radius of influence and monitor groundwater contamination. One SVE blower with an operating capacity of 300 cfm at 45 in of H2O vacuum.

Results and Next Steps:

Results to date:		The site lies within 3/4 of a mile of a river to the west, north, and east. Unusually high water levels in 2007 are believed to have led to a significant decrease (from 6,738 ug/L in September 2006 to 58 ug/L in January 2008) in groundwater concentrations (essentially flushing the groundwater). The soil contamination remains and groundwater contamination had rebounded significantly by March 2009 (to 66,800 ug/L) 4332.3 lbs of VOC's have been removed from the soil since start-up and the system continues to operate efficiently.
Next Steps:		Continue with remediation until clean-up goals are reached.

Costs:

Cost for Assessment:		$31,712.90
Cost to Design and Implement:		$33,985.00
Cost for Operation and Maintenance:		$5000-$8000
Total Costs for Cleanup:

Lessons Learned:

Lessons Learned:

Property owners can be valuable assets to knowledge of past operations. A property owner of over 50 years was able to identify source areas based on his recollection of past operations. Property sales provide a good window for conducting investigative assessment activities, vacant buildings are easier to access. Used remediation equipment can greatly reduce costs. The installation of above-ground SVE lines was a good alternative to traditional trenching. It this case it was necessary to avoid underground utilities; however, it also reduced the system installation costs.
