With the help of our Model 703 Waterloo Emitter Operating Principles video series, let’s review how the Waterloo Emitter works, some tips for application, and the advantages it provides to remediation professionals. The Waterloo Emitter has been shown to be very effective at cleaning up sites contaminated with petroleum hydrocarbons, so let’s focus… Continue Reading »
An aquifer in Central Ontario became contaminated with BTEX and PCH F1 (Petroleum Hydrocarbons – Fraction #1i) from leaking underground infrastructure linked to a gas station. The groundwater in the aquifer flows between 3 -13 meters a year, as such, a voluntary cleanup of the aquifer was initiated to remediate the plume source, and to stop the dissolved plume phase from moving off-site.

To begin his presentation, Rick discussed the current trends in groundwater remediation. Over the past decade, in situ methods have greatly increased in popularity. Although the use of these approaches is growing, Rick pointed out some limitations. Geological heterogeneity is a limitation to determining hydrogeological aspects of a contaminated site, and how a reagent will… Continue Reading »
Vertex Environmental Inc., located in Cambridge, Ontario, specializes in the in-situ remediation of contaminated groundwater. In 2007 they were contracted to clean up a former gas station site in Guelph, Ontario. The contaminant plume containing gasoline and diesel occurs in unconsolidated silty sand to a depth of approximately 3 m (10 ft). The initial plume… Continue Reading »
