Vapour Intrusion Assessment and Mitigation Services
Vapour intrusion (VI) occurs when harmful vapors from contaminated soil or groundwater migrate into buildings, posing health risks to occupants. In Ontario, managing vapour intrusion is critical to ensuring safe indoor environments and complying with regulations under the Environmental Protection Act (EPA) and Ontario Regulation 153/04.
At Blastek, we offer comprehensive solutions to assess, mitigate, and manage the risks associated with subsurface vapour migration into indoor air. Our expertise covers the full spectrum of VI concerns, from initial site screening and investigation to the design, implementation, and long-term monitoring of mitigation systems. We understand the complex regulatory landscape surrounding VI and work closely with our clients to navigate local, regional, and national requirements, ensuring compliance and minimizing potential liabilities.
At Blastek, we specialize in identifying, assessing, and mitigating vapour intrusion risks to protect human health and ensure regulatory compliance.
