Air Quality/ Vapor Intrusion

Air quality and vapor intrusion issues can affect approvals, operations, and occupant health. ASTI supports clients with investigation, permitting, and mitigation services across Michigan and the Great Lakes region. We coordinate closely with EGLE and the EPA to help clients move from assessment to approval without unnecessary delays. Our work turns complex regulatory requirements into clear, achievable steps.

Indoor Air Quality Investigation

We investigate indoor air risks and provide practical recommendations. Reports support redevelopment, mitigation planning, and compliance.

Air Permitting

We guide clients through permitting efficiently and accurately. Submittals are complete and compliant to minimize delays.

Air Dispersion Modeling

We perform dispersion modeling for permits and impact evaluations. Results are defensible and meet regulatory expectations.

Vapor Intrusion Assessment

We assess vapor intrusion risk and deliver clear, actionable data. Findings support mitigation design and regulatory coordination.

Vapor Mitigation System Design

We design effective mitigation systems tailored to site conditions. Designs meet requirements and support reliable performance.

Vapor Mitigation System Installation Oversight, Maintenance, and Monitoring

We provide oversight and monitoring to confirm mitigation systems perform over time. Documentation supports ongoing compliance and operations.
