Overview – Green and Sustainable Remediation
Green vs. Sustainable Remediation
Principles of Practice, Policies,Guidance and Standards

Green Remediation Technologies
The Future– What we expect from a regulatory
perspective?– Where are the business
opportunities?

Green Remediation
Green Remediation – in general, incorporatesenvironmental factors– Environmental factors are generally considered to be the
following elements: energy, air emissions, water impacts,material and waste, and land and ecosystem
– A green remediation project incorporates various activitiesrelated to optimizing the various elements
• However, the implementation needs to be above and beyondwhat would be considered standard practice
– Only considers economic and societal factors to the extentrequired by existing regulatory requirements
– Level of analysis can vary from screening level evaluation tofull blown life cycle assessment
WSP Environment & Energy
Green vs. Sustainable Remediation
Green Remediation– EPA Definition: “The practice of considering all
environmental effects of remedy implementation andincorporating options to maximize net environmentalbenefits.”
Definition of Sustainable Remediation– SURF Definition: “Sustainable remediation is broadly defined
as a remedy or combination of remedies whose net benefiton human health and the environment is maximizedthrough the judicious use of limited resources.”

Sustainable Remediation Triple Bottom Line Accounting
– Environmental Factors• These are better established, namely because
these can be evaluated from a technicalperspective by environmental professionals
– Economic Factors• From a cost perspective, these can be
evaluated; however, evaluating the economicvalue brought to the community is more difficultto measure
– Societal Factors• Screening level analysis is relatively
straightforward; however, quantitative analysisis difficult
Level of analysis can also vary fromscreening to full-blown life cycle assessment

Formed in 2006
Voluntary industry-government-academic organization
Enthusiastic - almost 100% voluntary membership
Focused on principles, outreach, information disseminationand study of the practice

ASTM Green & Sustainable CorrectiveAction Standard Practice
Most likely to become industry standard adopted by EPAand states
Will not be a stringent practice standard, but will be a guideby definition
To incorporate environmental, societal and economicissues on a flexible basis
Likely to be a tiered approach – screening, qualitative &quantitative tier options
Draft standard will not be complete for at least one year

ASTM Framework for Green & SustainableRemediation
Green & Sustainable Remediation is a Process, not aTechnology– GSR principles should be integrated into cleanup projects– Applied on a phase-by-phase basis– Is not just about green technologies– Best management practices that are
incorporated into projects
WSP Environment & Energy
ASTM Standard Guide Outline
Purpose of Standard Guide How the Standard Guide is Being Developed Structure
– Green Remediation– Sustainable Remediation
• Green + Economic & Social
– Tiered Evaluation• Qualitative Evaluation (Best Management Practices)• Quantitative Evaluation (Numerical)
– Standard is applied on a phase-by-phase basis1. Site Assessment2. Remedy Selection3. Remedy Design and Implementation4. Operation, Maintenance and Monitoring5. Remedy Optimization
WSP Environment & Energy
Management Practices (ASTM Standard)
Standard Management Practice– A practice that you are considered industry standards
and are truly basic in nature• Recycling office waste• Using compact fluorescent light bulbs• Minimizing paper use with electronic filing systems
Best Management Practice– Activity that improves the environmental, economic, or
social aspect of a cleanup project or the site itself– ASTM is developing a list of both basic BMPs and
significant BMPs• Significant is a BMP that requires an increased level of effort and
results in a greater net benefit
WSP Environment & Energy
ASTM Standard Guide – Green Remediation
Best Management Practices– BMPs drive sustainable remediation– BMPs are organized on a technology or activity basis, but are
applied based on the phase of the project– Green BMPs follow EPA’s five core elements
1. Energy2. Air Emissions3. Water Impacts4. Material and Waste5. Land and Ecosystem
– ASTM is attempting to establish a “bar” for the minimumnumber of BMPs that need to be incorporated into a project inorder for it to be considered Green or Sustainable
WSP Environment & Energy
ASTM Standard Guide Process
Two Tiers of Evaluation– Qualitative– Quantitative
Qualitative Evaluation has a 5-Step Process1. Standard management practice review and selection2. Best management practice opportunity assessment and screening3. Best management practice screening4. Best management practice implementation5. Measurement and documentation

Green Remediation – Quantitative Analysis
Two Types of Quantitative Analysis1. Environmental Footprint Analysis2. Life Cycle Assessment
Purpose of Quantitative Analysis– Technology Evaluation
• Use to compare metrics between different technologies– Quantify Metrics
• Develop methodology for calculating net environmental benefits– Opportunity Evaluation
• Identifying where the biggest net benefits are within a project
WSP Environment & Energy
Life Cycle Assessment
WSP Environment & Energy
ASTM’s Sustainable Remediation Track
The Sustainable Track = Environmental + Economic/Social Sustainable Core Elements
– Collaborative participation– Community livability– Individual quality of life– Net economic benefits– Economic risk reduction
Quantitative Metrics– Increased wages to the community during remediation– Jobs during and following remediation– Resources purchased locally– Other social or economic benefits– Environmental metrics/benefits (lower risk, fewer emissions,
other core elements)
WSP Environment & Energy
Green Remediation Applications – Pump &Treat Environmental Factors
Groundwater Extraction– Energy, materials, water, dewatering effects
Air stripping– Energy for blower– Materials for cleaning stripper
Off-gas Treatment (Granular ActivatedCarbon)– Air emissions– Materials (GAC)– Waste (GAC)
Discharge to Surface Water– Net water loss
Building Operations Long-Term Operations Fact: 1 hp uses 240K kWh over 30-year
period
WSP Environment & Energy
Pump & Treat Technology – Greening Consider Source Control Technologies to Limit Time of Applications Alternative Energy Use
– Solar or wind either sourced onsite or offsite– Use variable frequency drives instead of throttling
Groundwater Extraction– Consider pulsed system operation– Manage flows– Replace water via injection
Air stripping– Energy for blower– Materials for cleaning stripper
Activated Carbon– Regenerate instead of disposing
Materials & Supplies– Source from local vendors– Recycle as much waste as possible
Discharge to Surface Water– Net water loss
Building Operations– LEED aspects, recycling, energy efficiency, building materials

Solar energy used to operate six recovery wells, includingpump motors, aerators, and blowers
Transfers extracted ground water into a biologicallyactivated carbon treatment system
Obtains 350,000 kWh of electricity, which meets 20-25% ofthe P&T system's energy demand
Eliminates 571,000 pounds of CO2 emissions annually Prevents emission of 1,600 pounds of SO2 and 1,100
pounds of NO2 each year Site is being redeveloped as a port facility

What does the Future Hold for GSR?
How will GSR be incorporated into regulatoryframeworks?– Guidance, policy, or regulation?– Federal or provincial level?
What other government drivers may be utilized?– Government contracting– Governmental orders– Sunfields and windfields– Tax incentives– Grants– Carbon credits– Natural resource and wetland banking
WSP Environment & Energy
What does the Future Hold for GSR? (cont.)
What are future business opportunities for GSR?– Drive remedy selection on an ad hoc basis?– Will ASTM standard be incorporated into regulations or
guidance?– Will GSR be included in federal, provincial, local, and
private investigation and remediation solicitations?– Will new products be developed?
