THE STORY ARC MODEL: REMEDIATING A GASOLINE-IMPACTED, DOWNSTREAM SITE IN CENTRAL ALBERTA
Lennox, B. | EnviroTech 2020, 11-12 June, Virtual Event, 2020
The story arc model, normally used as a literary device, was adapted to illustrate environmental site management and remediation activities, i.e., how gasoline impacts were identified through assessment and monitoring activities within a bedrock aquifer in a period of about 10 years. Results of these activities initiated a multi-stage remediation program that included installing and implementing a full-scale multi-phase extraction (MPE) system. After tailing system performance and attempts to optimize the system were unsuccessful, the MPE system was turned off, and on-site peroxide injections were completed. As of 2018, groundwater quality concentrations generally met risk management endpoints at off-lease oxidant injection wells, and pore water samples were less than surface water guidelines. In anticipation of remediation endpoints being met, natural attenuation parameters are being monitored to establish a long-term record of the degradation of hydrocarbons by naturally occurring microbes.
