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 »
A study was undertaken to determine the success for aerobic bioremediation of aromatic hydrocarbons (BTEX) and MTBE (methyl tert-butyl ether) in high temperature, saline groundwater conditions. The study included laboratory microcosm experiments, as well as a field trial in Saudi Arabia, in which Solinst Waterloo Emitters were used. To view the full… 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.

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 »
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 »
