Rodak Engineering has
merged into Duncklee & Dunham. As a result,
Duncklee & Dunham now offers engineering
services such as air pollution control design
and permitting, stormwater design permitting and
monitoring, wastewater system design, point of
entry treatment system design and construction,
soil and groundwater treatment system design,
and environmental compliance auditing and
management system support. For more information
about our engineering services, please contact

Duncklee &
Dunham has been a NC DENR Registered
Environmental Consultant (REC) since 1998 and
has three DENR approved Registered Site Managers
(RSMs) under the REC Program. Duncklee & Dunham
RSMs are managing four active REC site projects
involving metal, chlorinated solvent, and
nutrient contamination in soil and ground
water.

Dave Duncklee, Tom Dunham, Daphne Jones, and
Bryson Trexler of Duncklee & Dunham and Andy
Rodak of Rodak Engineering recently attended the
2010 Southeastern In Situ Soil and Groundwater
Remediation Conference to maintain our edge in
In Situ Chemical Oxidation (ISCO), In Situ
Chemical Reduction (ISCR), and
bioaugmentation technologies. The technical
presentations, as well as interfacing with other
consultants, scientists, and regulators, proved
to be valuable.

Dave Duncklee
remains active in the Association of
Environmental and Engineering Geologists (AEG),
currently serving as treasurer on the Carolinas
Section board, as short course committee chair
on the AEG Charleston 2010 national meeting, and
as co-chair of the national AEG continuing
education committee. Dave has also recently been
approved by the Interstate Training and
Regulatory Council (ITRC) to participate in the
newly formed Environmental Molecular Diagnostics
team.

Duncklee &
Dunham's Bryson Trexler is
using innovative techniques to develop site
specific soil clean-up levels and develop a
ground water variance for site metals
restoration. The site is under the REC program
and currently being managed on a fast track
basis to accommodate expedited clean-up of soil
and groundwater once plant modifications are
made.
Duncklee &
Dunham is preparing to implement full scale
injection plan involving sodium persulfate into
shallow groundwater under and adjacent to a
former manufacturing building. A corrective
action plan and an injection permit were
submitted and approved under the Ga EPD HSR
program.

Congratulations to Jayson Kilcoyne on his
promotion to Project Environmental Scientist II.
His efforts are currently concentrating on the
assessment and remediation of agrichemical and
petroleum UST projects.
October 2009
In partnership
with a local law firm, Duncklee & Dunham has
recently provided pro bono professional
assistance to Hope Elementary Charter School in
Raleigh, North Carolina. Work was conducted to
assess and dispose approximately three tons of
soil, potentially contaminated with lead-based
paint, from the school property. The closure
report was submitted to the school in October
2009.
April 2009
Duncklee & Dunham is performing our third GIS
brownfield inventory project for a local NC
municipality. This project is being performed
for several hundred parcels and will be
completed in approximately five weeks time start
to finish.
March 2009
Duncklee & Dunham has
completed a 1,700 parcel GIS brownfields
inventory for a local NC municipality. Muti-parcel
Phase I ESAs are currently being performed under
this US EPA brownfields grant funded project. To
our knowledge, this is the second GIS
brownfields inventory completed in NC, both of
which have been performed by the firm. Dr.
Trexler is currently working with US EPA Region
4 to finalize a QAPP so that phase II assessment
tasks can be implemented using the brownfield
grant funds.
February 2009
In a joint effort with
Rodak Engineering, Duncklee & Dunham is in the
process of performing over one hundred SPCC
plans across the US. Duncklee & Dunham has
prepared over 900 spill plans across the US over
the past ten years.

orination
and de-chlorination) disinfection processes, and were
designed for peak flows of 0.5 MGD and 1.83 MGD,
respectively. The ultraviolet light disinfection
system employed a bank of lights installed within a
stainless steel open channel, with outlet serpentine
weir flow control and built-in automation. The
chemical disinfection system employed tablet
dissolution into a liquid feed injection system
through a baffled open channel flow regime, with
built-in automation (variable feed through ORP
control). Both systems were permitted through the
North Carolina Division of Water Quality’s
Construction Grants and Loans Section. The ultraviolet
light system was installed in late 2007, and is
performing as designed. The chemical disinfection
system began operation in Spring, 2009.
