Tuesday, October 17th, 2017

Caltha LLP Project Summary

Project: SBA Vapor Intrusion Risk Study
Client:
National Bank
Location(s):
Saint Paul, Minnesota

Key Elements: Site investigation, subslab soil vapor testing, vapor encroachment, Small Business Administration loan

Overview: Caltha LLP conducted a Soil Vapor Intrusion Risk Assessment for this commercial property located in St. Paul. The Phase 1 assessment conducted a Tier I Vapor Encroachment Screening Assessment using ASTM E2600-10. This assessment determined that the potential for risks of vapor intrusion could not be screening out, therefore a Phase 2 vapor intrusion risk study was recommended.

An investigation approach was prepared which met the requirements of ASTM E1903-11 (Standard Practice for Environmental Site Assessments: Phase II Environmental Site Assessment Process). Subslab soil gas samples were collected from inside the building. Results were compared to MPCA vapor intrusion screening values. Although some volatile organics were detected in subslab soil gas, all concentrations were below agency risk-based screening values.
