  1. Oxygen Release Compound (ORCÒ) Timely, Cost-Effective Solutions for Accelerating Natural Attenuation

  2. What is ORC? • A proprietary time-release formulation ofmagnesium peroxide (MgO2) • Used for accelerated bioremediation of aerobically degradable contaminants • Chemistry • MgO2 + H2O 1/2 O2 + Mg(OH)2

  3. ORC’s Patented Time-Release Feature • Typical MgO2 releases oxygen for only 3-4 weeks due to “Lockup” • Typical CaO2 releases for 3-4 weeks (Lockup) and presents pH problem • Patented structure of ORC crystal allows for continued release of oxygen by avoiding Lockup and moderate pH

  4. ORC’s Patented Time-Release Feature • Extended oxygen release profile • Magnesium peroxide crystalline structure intercalated with food-grade phosphate • Releases oxygen for up to 6 to 12 months • Environmentally Safe • Insoluble Mg compounds maintain moderate pH levels (Ksp = 1.8 x 10-11) • Safe reaction by-product : solid Mg(OH)2 or “Milk of Magnesia”

  5. Benefits of ORC’s Time-Release Feature Rapid Site Closure - Accelerates natural attenuation by 10X to 1000X—reducing time to site closure Cost-Effective - No capital costs for systems - No operation & maintenance costs - Reduced installation costs

  6. ORC vs Other Technologies ORC vs Monitoring Only • *All values were derived independently by the sites’ consultant. The costs are full system costs with the objective of site closure

  7. Benefits of ORC’s Time-Release Feature Non-invasive • In-situ technology minimizes physical disturbance to property Wide regulatory acceptance • Installed in all 50 states of US Proven technology • Installed on >6,500 sites worldwide

  8. Aerobically Degradable Compounds • Petroleum Hydrocarbons • BTEX • Alkanes (diesel, fuel oil, etc.) • Alcohols • Ketones • MTBE • Vinyl Chloride • Etc.

  9. Oxygen Release Compound (Applications) • Saturated Zone Source Treatment • ORC slurry injected into source area • Excavated Tank Treatment • ORC applied as backfill amendment after UST excavations • Oxygen Barrier-PRB • ORC socks or slurry applied downgradient to cut-off leading edge of plume or upgrad- ien to sweep oxygen across plume

  10. Source Treatment with Slurry Injection Application ORC slurry is poured into the hopper of a Slurry Injection Pump ORC powder is mixed with water to form a slurry Direct-push injection of slurry

  11. Is ORC right for your project?Follow these steps to find out! • Step #1 – Contact Regenesis Technical Support for a free site evaluation, cost estimate and proposal. • Step #2 – Evaluate free ORC Proposal, determine if it meets your requirements and goals • Step #3 – If so, you can order ORC directly from Regenesis over the phone at (949) 366-8000

  12. Steps to obtaining HRC - contn’d • Step #4 - ORC is typically shipped by truck, and is delivered in 30 lb. buckets or Filter Socks as specified *Note: MSDS and installation instructions are supplied. • Step #5 - Receive product and apply to your site.

  13. REGENESIS SUPPORT Regenesis offers support free of charge: • ORC engineering/design services • ORC application/installation tech support www.regenesis.com • Technical Bulletins with • Case Studies • Peer-reviewed Literature • Download the Applications and Real Estate Software
