Case Studies

Situation:

Approximately 600 litres of heating fuel discharged from the holding tank inside the garage adjacent to the home
Oil had migrated beneath into the bedrock and made its way into the well which supplied the home
Oil was seen coming from the taps of the home
Three car garage, all brick, raised bungalow of approximately 4000 sq.ft built on top of limestone bedrock

Task:

Emergency cleanup procedures:

Established clean water supply for residence and flushed plumbing system
Used existing water well as recovery well and installed Mobile Treatment Unit (MTU) to establish hydraulic containment

Use Chemical Oxidation using Stabilized Hydrogen Peroxide:

Used BIM200 to remediate impacted concrete floor
Installed screened wells along perimeter of impacted zone
Installed injection point at source of impact
Installed injection system connecting all wells
Used existing water well as recovery well, injected stabilized hydrogen peroxide into screened wells and drew towards recovery well
Upon achieving MOE compliance standards, decommissioned former water well and installed new well up stream as water supply

Result

Successful remediation achieved in 4 months
Saved the home
Home owners continued to live in the house during the remediation process

Brockville, Ontario

Oil Spill In Bedrock

Sault St. Marie, Ontario

Oil Spill Under Home and Into Lake

Situation:

Approximately 756 liters of heating fuel discharged from the holding tank located at the rear of the home
Oil had migrated under the home, into an abandoned O-pipe, down to the beach and approximately 150ft. into Lake Superior under the ice.

Task:

Emergency cleanup procedures:

Excavated immediate impact area
Installed Mobile Treatment Unit to establish hydraulic containment
Installed containment booms along lakeshore perimeter

Use Bio-Remediation and Mobile Treatment Unit (MTU) to achieve remediation:

Applied BIM200 to foundation of home
Used bio-remediation to remediate soil under home
Bio-piled contaminated ice and snow. As the contaminated water thawed, run off was captured and pumped through MTU

Result

Successful remediation achieved in 12 months
Saved the home
Home owners continued to live in the house during the remediation process
Saved large trees on the property

Huntsville, Ontario

Oil Spill Under Home On Lake

Situation:

Approximately 900 liters of heating fuel discharged from the holding tank adjacent to the home
Contamination was visible on the basement wall
Oil had migrated beneath the concrete basement floor
Property consisted of many mature trees. Steep slope toward the lakefront approximately 60 feet from the home.

Task:

Emergency cleanup procedures:

Excavated and removed contaminated soil down to the footings of the home in impact area
Installed a recovery well and Mobile Treatment Unit (MTU) to treat contaminated groundwater
Placed containment booms in the lake to prevent further possible migration into the lake

Use Bioremediation and MTU to Remediate Site:

Continued use of the MTU for groundwater remediation
Removed section of basement concrete floor to gain access to the subfloor contamination
Applied microbes and nutrients to degrade the contamination
Monitored and maintained microbial remediation until compliance with MOE standards was achieved.
Erected a retaining wall to prevent erosion where soil had been excavated, and placed an insulated winterized cover over the exterior impact zone so that bioremediation can continue during the winter months
Upon achieving MOE compliance standards, made necessary repairs to basement floor and landscaped exterior impact are

Result

Successful remediation achieved in 14 months
Saved the home
Saved the mature trees and picturesque landscape
No disturbance to the lake shore

Pigeon, Nova Scotia

Oil Spill Under Home

Situation:

Approximately 600 liters of heating fuel discharged from the holding tank adjacent to the home
Contamination visible on the basement wall
Oil had migrated beneath the concrete basement floor to opposite side of home
Multiple additions and extensive renovations had been done on the house

Task:

Emergency containment and cleanup procedures:

Excavated and removed immediate impact area down to the footing of the home
Applied BIM200 to outside foundation wall, inside foundation wall, above concrete floor and under concrete floor
Placed containment booms in nearby pond and capture dams in ditch as precautionary measures

Use Bio-Augmented Chemical Oxidation to Remediate Soil and Groundwater:

Installed gravity feed injection tubes in area of former AST
Inject Sodium Persulfate and Calcium Hydroxide oxidative amendment
After initial oxidative event culture and inject hydrocarbon digesting microbes

Result

Successful remediation of both soil and groundwater in 12 months
Saved the home
Family continued to live in the home during the remediation process

Mt. Pearl, Newfoundland

Oil Spill Under Home

Situation:

Approximately 600 liters of heating fuel discharged from the holding tank adjacent to the home
Oil had migrated beneath the footing of the home and partially under the basement floor
Oil had migrated along the side and back of the home via weeping tile
Large home with fully finished basement
Soil impacts only. No groundwater impacts detected

Task:

Emergency containment and cleanup procedures:

Excavated and removed immediate impact area down to the footing of the home
Applied BIM200 to outside foundation wall, inside foundation wall and along weeping tile

Use Bio-Augmented Chemical Oxidation to Remediate Soil and Groundwater:

Installed gravity feed injection tubes in area of former AST
Inject stabalized hydrogen peroxide oxidative amendment
After initial oxidative event culture and inject hydrocarbon digesting microbes

Result

Successful remediation in 10 months
No underpinning and saved the home
Saved impact on neighbours property
Family continued to live in the home during the remediation process
