Delivering Sustainable Remediation Solutions

To effectively manage environmental liabilities and return sites to beneficial reuse, today’s clients

must maintain a delicate balance between cost-effectively meeting regulatory obligations,

mitigating risk, and considering environmental stewardship interests. Environmental managers

must weigh not only the site-specific challenges and advantages of a particular technology, but

also the cost, regulatory drivers, associated risk, and sustainability opportunities. To navigate the

complexities of successful remediation management, CDM Smith partners with clients to develop

site-specific strategies tailored to meet individual needs.

Whether increasing property value by restoring sites for reuse, applying innovative technologies–

like bioremediation–or designing risk-based closure strategies, CDM Smith uses proven techniques

to provide total cost savings. CDM Smith combines comprehensive knowledge of regulations,

permitting requirements, and compliance strategies with technical expertise in innovative

Delivering TechnicalInnovation in Remediation

While completing numerous remediation designs over the past 30 years, CDM Smith has developed

innovative technical approaches and new assessment and remediation technologies to achieve

optimal results. For example, CDM Smith was one of the first to use on-site, real-time analyses and

data interpretation tools to accurately identify data gaps and quantify the extent of contamination;

electron microprobe techniques to determine the source, type, and bioavailability of contamnants;

and multivariable statistical techniques to determine the source of groundwater contamination—

approaches that have since become standard protocol. CDM Smith has won more than 35 awards

for innovative solutions to some of the most complex hazardous waste site challenges.

As an active member of the Interstate Technology & Regulatory Council (ITRC) Industry Affiliates Pro-

gram (IAP), CDM Smith regularly demonstrates its preeminence as a leader in innovative remediation

strategies and technologies. In fact, CDM Smith has won numerous awards from the ITRC, has been

major contributors to ITRC technical guidance documents, and has served as instructors for Internet

training courses. In addition, CDM Smith serves on the ITRC Board of Advisors as the IAP repre-

sentative. Our active participation in ITRC also helps us to stay current on the latest technological

advances of our colleagues in academia and industry, as well as trends in the regulatory community.

Remediation Portfolio Management - CDM Smith regularly provides turn-key man-

agement of large remediation portfolios for multi-year contracts while helping our clients

minimize risk, reduce life-cycle remediation costs, and bring sites to sustainable closure.

CDM Smith integrates our client service model with our client business processes to provide

prioritized, high-value remediation services that align seamlessly with our client’s needs.

This understanding of our clients’ technical, financial, safety, and regulatory requirements

and programs enables us to manage multiple projects simultaneously, in accordance with

their business programs and goals resulting in a beneficial and successful partnership.

Our vast experience implementing and

optimizing a wide array of remedial

technologies allows us to recognize and

pursue appropriate remedial solutions

based on practical experience, not just

theoretical or published information.

CDM Smith’s remedial designs include

new and innovative technologies as well

as traditional methods in combinations

that provide optimal reliability and cost

effectiveness.

CDM Smith uses risk assessment as

an integral part of comprehensive

strategies for management of

hazardous materials sites.

Site ClosureCDM Smith realizes that no cookie cutter approach exists

when moving sites from the investigation phase to obtaining

site closure. While on the surface, two sites may look similar,

when evaluating the social, economic, and environmental

aspects using a holistic sustainable approach, the prescribed

remedies for each site may be completely different. Accord-

ingly, when developing each site management strategy, we

identify all critical success factors and then work backwards

from the desired end result to identify and implement the

necessary tasks to achieve closure. By continually assessing

the information gained and data generated through the vari-

ous remediation phases, CDM Smith maximizes the efficiency

of sustainable remedies and refines necessary components,

while moving the site towards closure and potential reuse.

Risk AssessmentCDM Smith has successfully saved clients millions of dollars

in cleanup costs by developing risk-based strategies that gain

regulatory acceptance and subsequently bringing sites to

closure. Our practical site-specific approach to human health

and ecological risk assessment is both realistic and technically

defensible. The early involvement of risk assessment experts

and the development of accurate conceptual site models

result in accurate site characterization, appropriate cleanup

approaches, and regulatory strategies that consider the in-

tended future use of the property and guide remedy selection

as part of an overall sustainable remediation strategy.

Remediation Construction CDM Smith has been designing, constructing, and operating

remediation systems at contaminated sites nationwide

for over 25 years. These complex remediation projects

have encompassed soil excavation, in situ and ex situ

groundwater treatment, waste transportation and disposal,

decontamination and demolition, and wetlands restoration.

An important distinction that CDM Smith offers is an

integrated approach to remediation design / construction

projects. Our engineering and construction teams work

together to develop solutions that consider life-cycle

remediation costs, optimize technology selection, and

ultimately achieve site closure.

CDM Smith’s IndustrialRemediation Services

CDM Smith has been a leader in

developing and applying 3-dimensional

groundwater models for site evaluation

and remediation activities.

CDM Smith has been successful in saving

clients millions of dollars in cleanup costs

by designing risk-based site strategies

that gain regulatory acceptance.

CDM Smith aggressively makes use of

current and proposed regulations to

reduce total remediation costs.

Underground Storage Tank (UST) Removal and Soil ExcavationCDM Smith has conducted UST removals to support site closure

and to reduce inventory under asset management programs.

We have managed remediation involving the removal of USTs

and associated fuel and chemical impacted soils at thousands

of sites ranging in complexity from small single UST remov-

als, through multi-UST removal programs at retail petroleum

facilities, to large tank field programs at distribution facilities,

petroleum terminals, and refineries. CDM Smith has been in-

volved with numerous site closures where the remedial solution

involved the removal of USTs, fueling system infrastructure and

associated impacted soil. Throughout CDM Smith’s experience

we have developed standardized, UST specification and bidding

packages, UST removal work plans, and health and safety plans

that provide an array of existing tools to reduce overall cost.

Regulatory Agency / Potentially Responsible Parties (PRP) SupportCDM Smith works collaboratively with regulators to develop

and implement environmental compliance strategies that

strengthen our clients environmental programs and maximize

operational efficiency. By establishing reasonable exposure

scenarios, remediation goals, and compliance points, CDM

Smith achieves sustainable closure maximizing the increased

net environmental benefit and site reuse potential.

CDM Smith has also represented PRPs ranging in size from 3 to

142 parties providing extensive liaison support with local, state,

and federal regulatory agencies. CDM Smith couples the needs

of our clients with the knowledge of the regulator’s perspective

to achieve “win-win” outcomes wherever possible.

•Develop site-specific sustainability plans, (including goals and

performance metrics) as well as evaluate site reuse planning.

• Incorporate sustainability during remedial investigations via

the TRIAD approach, waste minimization, passive sampling

techniques, and biodiesel operated drill rigs.

• Select a sustainable remedy by evaluating the project

life-cycle, greenhouse gas emissions, energy and resource

use and conservation, and economic cost.

•Design and construct a remedy that

incorporates “green cleanup” principles.

•Develop “green designs” to address return on investment in

both capital and long-term operations and maintencance costs.
