“Omaha is a run play, but it could be a pass play or a play-action pass, depending on a couple things: the wind, which way we’re going, the quarter, and the jerseys that we’re wearing. It varies, really play-to-play. So, there’s your answer to that one.”
– Peyton Manning
Selecting a winning strategy for in-situ remediation of Petroleum Hydrocarbon (PHC) impacts is not unlike calling plays in football.
There are many factors that should be considered in the decision making process such as field position (concentrations relative to numeric criteria), strength of the defence (geology – permeability), and time on the clock (desired or required closure date), to name a few. Unless you are certain to execute a Hail Mary, in-situ remediation usually requires the combination of two or more technologies to reach the end zone. Whether you are new to the remediation game, or a seasoned practitioner, a pundits look at in-situ remediation through a football analogy will offer RemTech delegates a fresh and fun view of the technologies available and relevant in Canada.
Through their project experiences, literature reviews, and participation at industry forums such as RemTech, Matrix remediation specialists have developed a playbook of remediation options to help clients make informed decisions on which technologies are best-suited for their remediation challenges. The playbook will help remediation practitioners systematically navigate through the many options available and more closely examine those likely to provide a successful outcome.
During this presentation, several offensive and defensive plays will be drawn up and the major factors contributing to, or limiting in-situ remediation success will be discussed. Typical remediation timeframes and costs will be identified at a rudimentary level, and technology combinations from project sites will be explored as examples. Offensive formations in the playbook include the Shotgun (vacuum and thermal technologies), Splitback (chemical oxidation and enhanced biodegradation technologies), and I-Form (LNAPL pumping). Defensive formations in the playbook include 3-4 Front (barrier and cutoff walls), and Cover 2 (permeable reactive barriers).
