REPEAT THE QUESTION PLEASE!
What are some areas of concern with Brownfield sites that may be
overlooked on an initial walk through?
Impacts to soil and/or
groundwater at unexpected
locations,
Asbestos-containing materials
above a second ceilings or
behind walls,
Large concrete foundations
previously used for
supporting and anchoring
machinery,
Buried sumps, pits, drywells,
or elevator shaft and pistons,
Buried solid waste areas, such
as coal or trash; and,
Basement or floor slabs
beneath newer floor slabs.

Completing a Successful Remediation Project
By: Jeffrey Nee, P.E., Senior Project Manager
A contaminated property represents nothing more than a liability on the
balance sheet or a roadblock in the development of a community. The successful
remediation of a contaminated property can be difficult due to the maze of
State and Federal regulations (Who can remember what RCRA stands for?);
difficult to pronounce chemical names (Let's all say hexachlorocyclopentadiene
together.); and remedial technologies that allow us engineers to sound smart
(Which do you think will be most effective for the remediation of
dissolved-phase impacts? - high-vacuum, dual phase extraction or in-situ
chemical oxidation using hydrogen peroxide?)
QEPA and its associate, QEPI, have an expert team of licensed engineers,
geologists and toxicologists to assist you or your clients with any of your
remediation needs - soils, groundwater or surface water. We believe, an
understanding of three key factors are essential for the success of any
remediation project:
1) Understand the Client's Objectives - What will the property be used
for? What is the ultimate goal of the client? What is the client's timeframe
for cleanup? What is the client's budget?
2) Understand the Property Conditions - What is the property history?
What is the magnitude and extent of contamination? What is the hydrogeology
at the property? What are the potential receptors?
3) Understand the Regulations - What remedial program applies to the
property? Are calculated, site-specific closure levels applicable? Can an
institutional control be implemented?
No doubt there are numerous consultants that are capable of designing a
remedial approach, such as an air sparge/soil vapor extraction (AS/SVE)
system. However, if these three key factors are not understood, even the
best-engineered AS/SVE system will not result in a successful remediation
project for you or your client. We believe that a successful remediation
project should be nothing less than achieving the remediation goals for
your property using a cost-effective remedial approach.
