The following list of sites is organized according
to technology to provide an overview of the extensive hands-on experience
within P. E. Haas & Associates, LLC. We believe that if
you have not worked directly with a technology, you do not really
know that technology.
Site Characterization (e.g. TRIAD)
Deep multilevel ground water profiling results in the detection of two uncharacteristically long (e.g. 1,200-1,600 foot long) and diving dissolved benzene plumes at Galena Airport, Alaska.
Conduct of adaptive site
characterization at former fire protection training area where a
discrete distribution of perchloroethene was detected in ground
water at 17-66 mg/L. Under this effort, 3-4 discrete depths
at each of 72 locations were sampled and analyzed in the field within
16 days of field work. Previously undiscovered portions of
5 distinct chlorinated solvent plumes were identified and delineated
under this single mobilization. 16 days of adaptive site characterization
produced more than the previous 15 years of site characterization
and remedial investigation activities!
Conduct of electromagnetic
borehole flowmeter logging in Spain to determine preferential ground
water flow zones and hydraulic conductivity profiles and their effects
on contaminant fate and transport at an Air Base in Spain.
Adaptive site characterization
effort in Charleston, SC which included the installation of discretely
screened monitoring wells using a direct push rig in an area where
previously undiscovered trichlorethene DNAPL at 390 mg/L in ground
water was discovered. Prepacked well screens and bentonite
seals were used for rapid cost-effective deployment and to ensure
high well integrity.
Stream-lined site characterization
of chlorinated solvent plume at King Salmon Airport, Alaska.
Ground water sampling, field chlorinated solvent analysis, plume
mapping, and final monitoring well installation conducted during
one mobilization with all necessary equipment on the rig.
of an electromagnetic borehole flow meter to delineate vertical
intervals of higher permeability. This testing is essential
to the proper understanding of potential preferential contaminant
flow paths as well as the design of organic substrate injection
to promote the anaerobic dechlorination of chlorinated solvents
investigation conducted at Galena Airport, Alaska to complete a
due diligence on potential sources of volatile organic contaminants
of injection and monitoring wells for enhanced bioremediation of
TCE-contaminated ground water via edible oil emulsion at King Salmon
Air Station, Alaska. Results from previous days sampling and
field chlorinated solvent analysis were used to select well locations
and screened intervals.
Expedited site characterization
at former Wurtsmith AFB, MI using a multilevel ground water grab
sampling and pneumatic slug tests, a field VOC lab, GPS, and field
Eielson AFB, AK - Natural
attenuation with long-term monitoring of chlorinated solvents at
Reservation Landfill No. 1 - "Natural attenuation removes 5700
pounds of chlorinated solvents over 50 years; 1.6 million gallon
per day pump and treat system removes 76 pounds over 50 years"
Project achieves $140M cost avoidance.
England AFB, LA Site SS-45
- Natural attenuation with long-term monitoring approved under RCRA
remedial action plan on 240 acre chlorinated solvent plume
Effective project management results
in the installation, 2-year operation, and monitoring of 35
bioventing systems for <$45K/system
evaluation at South POL Tank Farm Galena Airport, AK. -35F
Free Product Recovery
LNAPL baildown recovery
testing conducted at King Salmon Airport, AK for recovery feasibility
of a subslab depressurization system at Galena Aviation Technical
Center, Galena, AK.
Deployment of diffusion
bag samplers to define vertical contamaminant concentration profiles
in a monitoring well in Spain that is within the capture zone of
three drinking water production wells. Electromagnetic borehole
flowmeter, multilevel low flow sampling, continuous water level
logging, and multilevel diffusion bag samplers were deployed to
define potential contaminant entry locations into drinking water
King Salmon Airport, Alaska
- Shutdown of ground water seep collection systems likely to reduce
cost to complete by $40M
