Texaco former marine terminal, Thunder Bay ON
Managed the remediation of a former petroleum marine terminal located adjacent to the McKellar River. Project required the remediation of soil with a very high water table. All excavation activities required the management of groundwater and the building of temporary site roads to allow movement of trucks. Soil was remediated using bio-piles with nutrient amendments.

Imperial Oil former bulk plant passive biocell, Leaf Rapids Manitoba
Excavated impacted sand and silt materials, temporarily piled on-site, backfilled excavation below water table with unimpacted soil, backfilled impacted soil in lifts and sprayed with nutrients.

Shell Canada terminal, Winnipeg Manitoba
Reviewed site petroleum concentrations and phase-separated product plumes and prepared remediation options.

Various Clients, Site Remediation
Managed or supervised the on-site activities related to the remediation of petroleum impacted properties of over 30 sites in Manitoba, Saskatchewan, and Ontario. Many of the projects were located in the north.

Pioneer Grain Limited former fertilizer facility, Edam SK
Designed a field monitoring program to determine if subsurface conditions were appropriate for denitrification technologies. Installed a porous reactive denitrification barrier consisting of 200 m3 of sawdust mixed with the native site sands below the water table. Designed an acetic acid injection program to promote on-site denitrification.

Imperial Oil Limited fertilizer facility, Morden MB
Designed and supervised the installation of a wheat straw and sawdust porous reactive barrier for the removal of nitrate from groundwater. The barrier was installed along the downgradient property line for approximately 80 m to a depth of 6 m. Tracked and evaluated an acetic acid injection program for the denitrification of the site groundwater.

Shell Canada Limited former petroleum bulk plant, Brandon MB
Designed and monitored a nutrient and oxygen release compound injection program to remediate a sand and gravel aquifer impacted with petroleum hydrocarbons. Project included the evaluation of the site groundwater microbial populations and the natural water chemistry that may inhibit or promote degradation of the hydrocarbons.

Petro-Canada petroleum station, Brandon MB
Designed and monitored a nutrient and oxygen release compound injection program to remediate a sand and gravel aquifer impacted with petroleum hydrocarbons. Project included the evaluation of the site groundwater microbial populations and the natural water chemistry that may inhibit or promote degradation of the hydrocarbons.

Imperial Oil Limited former marine terminal, Thunder Bay ON
Used groundwater recovery trenches to recover shallow groundwater. The water was treated in an on-site constructed wetland and allowed to infiltrate back into the subsurface.

Pioneer Grain Limited former fertilizer facility, Edam SK
Designed and supervised the installation of two bentonite slurry groundwater barriers to prevent offsite migration of impacted groundwater and to direct the groundwater toward the treatment cell. To key the barriers into a low permeability clay layer located approximately 8 m below grade, the surficial soils in the areas of the barrier were subcut to allow the excavators to reach the clay. Powder bentonite was mixed with an oil field drill mud tank and pumped into the trenches to provide hydraulic shoring of the sand trench walls and to create a low permeability barrier.
