Demolition & Remediation
Decommissioning a PCB digester at a former Ministry of Environment training facility
Tri-Phase Environmental Inc. (TPEI) was contracted by the Ministry of Environment (MOE) in December 2010 to remediate a sewage treatment digester tank, with a capacity of three million litres and containing more than 1,500 cubic metres of sludge. The sludge contained high levels of heavy metals, but more importantly, polychlorinated biphenyl (PCB) levels in excess of 50 parts per million (ppm). These high levels classified the sludge as PCB waste as defined by the ministry’s regulations.

Quick action prevents environmental disaster
Tri-Phase Environmental Inc.’s (TPEI) emergency staff was called early one Sunday morning to respond to a polychlorinated biphenyl (PCB) spill in a downtown tower building. One of nine transformers containing PCBs had leaked Pyranol (a high level PCB liquid) onto the roof of the building which subsequently made its way into the rain water leader. Pyranol oil (DNAPL) spill response is a complex, challenging and cross-disciplinary skill, which requires highly specialized and experienced emergency staff. As such, TPEI dispatched an emergency response team that arrived on site within the hour to address the immediate needs of the spill.

Dealing with subsurface remediation
Subsurface Remediation includes identifying, quantifying and controlling contaminated source(s); considering cleanup levels required for each medium (air, soil, and ground water) to protect human health and the environment; and selecting treatment technologies based on information obtained concerning source(s) and cleanup levels.

Detecting and Eliminating Mould
Moulds are microorganisms that produce thousands of tiny particles called spores as part of their reproductive cycle. All mould contamination must be remediated.
