EPRI Fundamentals

• R&D generally performed by subcontractors (over 1600 ongoing projects)

• R&D not intended to develop alternatives for available suitable products

• Generalized research results accessible to public, commercialized (400 patents and 1000+ current products)

• EPRI owns results of research

Collaboratively Funded Manufactured Gas Plant (MGP) Site Management Issues

• Developing in-situ technologies that reduce or eliminate the need for “dig and haul”

• Forensics and Fingerprinting – MGP residuals– Non-Aqueous Phase Liquids (NAPLs)

• Off-site emissions/odor issues• Methods and techniques for remediating sediments• Human and ecological risks

Source Identification

Increasingly Weathered

• Using forensic techniquesto identify and measure degradation products of hydrocarbon-type contaminants

• Additional line-of-evidence for the effectiveness of natural and engineered remediation projects

MGP Remediation

• Typically relies on ‘dig and haul’ technologies

Testing alternative strategies when dig and haul is not an option

• Using In-situ Technologies instead of ‘dig and haul’– Advanced Chemical

Oxidation

• In-Situ Stabilization/Solidification

-Barrier walls along rivers

-Site wide solidification

-High pressure grouts
