EXPERIENCE
Rob has been employed in the environmental consulting and
remediation industry since 2002. His expertise includes
properly assessing complex and varied contaminated sites;
design, management, and oversight of Phase II
environmental operations; and budgeting, design,
management, and implementation of Phase III remedial
activities involving soil, soil vapor, and groundwater.
Rob has a working knowledge of a wide variety of
recalcitrant hazardous materials including volatile and semivolatile organic compounds, pesticides, and heavy metals.
Rob has experience in preparing proposals, work plans,
budgeting spreadsheets, health and safety plans, closure
reports, and post-remediation reports. He has field
experience in a wide variety of in-situ and ex-situ
remediation methods including oxidant and reductive
dechlorination chemical injection, groundwater and soil
vapor extraction, ex-situ direct treatment chemistry
application, and onsite waste classification and disposal.
KEY PROJECTS
Ex-Situ Chemical Oxidation – Former Wood Frame
Manufacturing Facility (Lester Prairie, Minnesota).
Onsite activities consisted of ex-situ remediation of vadose
zone soils contaminated with creosote compounds. Two
separate areas at the site were treated using Fenton’s
Reagent and Alkaline-activated Persulfate chemistries and
backhoe mixing methods. The treated soil was
subsequently classified and disposed of as non-hazardous
waste in nearby landfill. The client saved approximately
$500,000 compared with traditional dig-and-haul method.
In-Situ Chemical Oxidation – Former Dry Cleaning
Facility (Atlanta, GA).
Onsite activities consisted of in-situ sodium permanganate
injection to treat groundwater contaminated with chlorinated
solvents. Eighty-nine injection locations spaced in a grid
pattern were used to effectively disperse the permanganate
treatment chemistry into contaminated groundwater between
30- and 10-feet below ground surface. The treatment matrix
consisted of silty and clayey sand. This in-situ approach

saved the client $160,000 compared with traditional
remediation methods.
In-Situ Bioremediation – Chlorinated Solvent Superfund
Site (Long Prairie, MN).
Onsite activities consisted of pilot-scale in-situ EOS® injection
to treat groundwater contaminated with chlorinated solvents
via reductive dechlorination. Over a fourth month period,
Tetrachloroethene concentrations were reduced from 90
micrograms per liter (ug/L) to less than 5 ug/L. Performing
the pilot study demonstrated the effectiveness and feasibility
for utilizing EOS® to treat a National Priorities List Superfund
Site, saving the client $1,000,000 in full-scale costs.
In-Situ Oxidation and Bioremediation – Machine Shop
Facility (Oakfield, WI).
Onsite activities consisted of in-situ injection of EOS® and
sodium permanganate to treat groundwater contaminated
with chlorinated solvents. Total chlorinated solvent
concentrations of approximately 2,000 parts per million were
detected in the source area of the contaminated plume. A
strong solution of sodium permanganate was injected using
temporary injection wells into the source area of the plume.
Two “barrier wall” injections were performed downgradient of
the source area using EOS® to prevent further migration of
the plume offsite. Post-injection sampling has not yet
occurred.
Ex-situ and In-situ Oxidation – Former Diesel UST
(Minneapolis, MN).
Onsite activities consisted of ex-situ remediation using
Fenton’s Reagent treatment chemistry and subsequent insitu injection of alkaline-activated sodium persulfate.
Targeted contaminants in soil and groundwater included
gasoline range organics and BTEX compounds. Ex-situ
remediation using backhoe mixing methods was initially
implemented and targeted contaminated soils in the vicinity
of the water table. Confirmation soil/groundwater sampling
displayed successful remediation of vadose/capillary fringe
contaminated soil. Subsequent to excavation backfill, in-situ

injection was performed using alkaline-activated sodium
persulfate to remediate residual contaminated groundwater.
Excavation and In-Situ Injection – Former Dry Cleaning
Facility (San Leandro, California)
Office activities included designing injection application,
coordinating with subcontractors, and reporting. Onsite
activities included initial grid injection at approximately 100
locations using Hydrogen Reduction Compound (HRC) to
remediate chlorinated solvents. Subsequent onsite activities
included oversight of large-scale excavation including slot
trenching, excavation sidewall/floor confirmation sampling,
and subsequent excavation backfill and resurfacing. Total
Phase III project duration was approximately 14 months and
was accurately budgeted at approximately $1.2 million.
