Waterloo Emitters Provide An Ongoing Solution

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.

Site Characterization: Important To Remediation Design

Richard Jackson delivered a very interesting presentation on the need for accurate and complete site conceptual models when dealing with contaminated sites. Richard used four unique case studies to illustrate how important it is to “get it right”. Getting the model right, allows the right decisions to be made – especially when it comes to… Continue Reading »

Remediation Of A Former Gas Station Site – Within 6 Months!

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 »

New Enhanced Remediation Device

Researchers at the University of Waterloo have developed a device utilizing a patented technology to allow the enhancement of natural groundwater remediation processes. The device works by providing a regulated, steady application of any amendment material (ie. any chemical or biological stimulant), such as oxygen or hydrogen to encourage aerobic or anaerobic bioremediation. Manufactured and… Continue Reading »
