Cameron-Cole, LLC. (Cameron-Cole), on behalf of ABC Chemicals invites you to submit a proposal for
remediation services required at the ABC Chemical site located at 1234 5
th
Street in Anywhere Town, USA.
The contractor will review this Request for Proposal for information on the complete scope of work. This
work is being completed under a request by the AnyState Department of Environmental Quality (ADEQ)
under a Voluntary Corrective Action Order.
Project Background
Approximately thirteen years ago, a release of tetrachloroethene (PCE) occurred at the Mega Railroad
(Mega) railyard in Anywhere Town, USA. The exact location of the release was documented to be near the
southwest end of the former railyard depot. The spill occurred between the two northern-most mainline
tracks (Mainline 1 and Mainline 2 – both oriented east-west). The release originated from a 26 inch long
hairline crack on the underside of a tank car leased to ABC Chemicals for shipment of PCE manufactured
at ABC Chemicals manufacturing plant in Somewhere Else Town, USA. The tank car left the
manufacturing plant with approximately 14,800 gallons of PCE. The leak is believed to have begun
somewhere in transit. It is not known how much PCE remained in the tank car upon arrival at the Mega
Railyard in Anywhere Town. Based on surface staining and pooling of PCE, the immediate area of
contamination at the railyard appeared to be confined to a 200 foot x 10 foot wide section between the
mainline 1 and mainline 2 tracks. Mega personnel removed as much of the pooled PCE from the ground
surface as possible and covered the spilled area with plastic sheeting and ballast to minimize further PCE
mobilization.
A number of previous investigations and remedial actions have been conducted at the site. The
investigative work has identified PCE concentrations in vadose zone soil and dissolved in groundwater. In
addition, extensive contamination of the sub-surface from diesel fuel is present as a result of past Mega
operations. Free phase diesel is present in most areas showing impacts from PCE. PCE concentrations
have also been seen in the diesel free phase product. No free phase PCE has been identified, all of the PCE
impacts are associated with another phase (soil, groundwater or diesel). The following ranges are
indicative of the initial PCE impacts determined from site investigations:
Shallow Soils – 2.08 to 7309 mg/kg;
Deeper Soils – 37 to 249 mg/kg;
Groundwater – 0.011 to 170 mg/L;
Diesel – 14 to 17 mg/L
In addition, concentrations of trichloroethene (TCE), dichloroethene (DCE) and vinyl chloride (VC) have
been detected in groundwater. Some of the dissolved constituents have been shown to have migrated to the
north of the original spill and are now underneath the west wing of the former Mega Railyard Depot
Building. This building has served as a Museum for a number of years (approximately thirty) and the east
wing has recently been converted to a brewery and restaurant with offices, brewing equipment and storage
located in the basement.
As a result of the initial investigations and potential targets for exposure, two remediation systems were
placed at the Railyard. The first consists of two ozone generators placed in the center and west wing of the
former depot building basement to protect workers and visitors from chemicals volatilized into basement
air from underlying impacted groundwater. The second consisted of a dual-phase extraction pump coupled

to a soil vapor extraction system to remove free phase diesel and strip volatile chemicals from the vadose
zone. These systems were placed at the site in November 1989. Treatment of extracted liquid was via an
oil-water separator, air stripping and carbon polishing. Extracted soil vapor is not treated before venting to
the atmosphere based on low concentrations of contaminants observed in the vapor stream.
Based on diminishing recovery from the dual-phase extraction, the pump was shut down in May of 1997.
Approximately 1,000 gallons of PCE was estimated to have been recovered by the dual-extraction system.
The SVE system remains operational and is estimated to have collected approximately 10,400 pounds to
date. However, all quantities of recovered mass are considered to be estimates. There is a significant
fraction of residual diesel in the subsurface with associated PCE contamination. In addition, significant
concentrations of PCE and daughter products are still measured in groundwater.
Physical Setting
Site cross-sections show a shallow unit of fill, asphaltt and concrete that extends from 0 to 1 foot below
ground surface (bgs). An underlying unit of silty sand with gravel and clay lenses extends from 1 to 8 feet
in most wells. The main water bearing unit appears to be a sand layer underlain by a claystone/sandstone
which was observed at depths ranging from 17 to 24.5 feet bgs. This claystone/sandstone is believed to be
an aquitard to the vertical migration of contaminants from the source area.
Groundwater has risen approximately 2 feet since the dual-phase extraction well was turned off. Current
depth to groundwater fluctuates but averages approximately 10-15 feet bgs. The groundwater flow
direction is northeast with an average rate of 0.004 feet per feet. Authoritative text (Freeze and Cherry,
1981) estimates the hydraulic conductivity of water table unconsolidated silty sand with clay lenses to be
1x10
-04
centimeters per second (cm/s) to 1x10
-06
cm/s. The claystone/sandstone aquitard underlying the
water table unit is estimated to be 1x10
-06
cm/s to 1x10
-08
cm/s. The localized gradient in impacted area
appears to be reversed from the regional gradient at the site.
Scope of Work
The goal of this project is to complete a remediation of the ABC Chemical spill at the Mega Railroad
railyard in Anywhere Town, USA to satisfy requirements of the ADEQ. The client is ABC Chemicals and
therefore the contaminants of concern are PCE and associated chlorinated solvent compounds. ABC
Chemicals is highly cost conscious and would prefer not to spend money cleaning up ‘Mega’s problem’
the existing diesel plume. The two parties, Mega Railroad and ABC Chemicals, are willing to discuss joint
remediation schemes if costs can be amiably agreed upon. Proposals should be cognizant of costs and
whether costs are attributable to Mega or ABC. ABC is interested in exiting the site in a short time period
and is willing to entertain aggressive technologies if short remediation times can be accomplished. Finally,
ABC is very interested in reviewing any and all proposals generated from this Request for Proposals.
Proposals should include all elements necessary for completion of the remediation including any necessary
characterization, remediation strategy design, report preparation, implementation and potential operation
and maintenance.
Unless specified otherwise, all material, labor and equipment shall be furnished by the Contractor. The
Contractor shall be responsible for all materials and equipment in its custody or placed in construction by
it.
Project Schedule
The successful bidder shall plan to begin work immediately upon completion of the agreement between
Cameron-Cole, ABC and the contractor.
