CA Supplemental VI Guide

The California Department of Toxic Substances Control (DTSC) published an updated supplemental vapor intrusion guidance document. The recent CA VI guidance update includes a Continuous Monitoring section beginning on page 1-9.

That section references several peer-reviewed articles authored by VaporSafe team members. The Barometric Pressure Trends section on page 1-10 describes VaporSafe's ground-breaking efforts in correlating concentration variability with atmospheric drivers.
