Installing a vapor intrusion mitigation system is an important step toward reducing the movement of potentially harmful vapors into a building. However, installation alone does not guarantee that the system will continue working effectively. Post-mitigation monitoring evaluates system performance after installation. Through pressure measurements, inspections, and environmental sampling, project teams can confirm that the mitigation strategy remains protective as building and subsurface conditions change.

Low flow groundwater sampling is designed to collect representative water samples while minimizing disturbance inside a monitoring well. Instead of rapidly removing several well volumes, technicians pump groundwater at a controlled rate that limits drawdown, reduces sediment mobilization, and helps preserve the sample’s natural chemistry.
