Phase II Environmental Site Assessment <br />2534 Kenzie Terrace <br />WSB Project No. R-020198-000 Page 8 <br />Soil vapor results are summarized in Table 3. Concentrations that were found to exceed MPCA <br />regulatory criteria are highlighted on Figure 5. A copy of the laboratory analytical report is <br />included in Appendix C. The following is a summary of the soil vapor analytical results: <br />PID readings were 0.0 ppm while collecting the soil vapor samples. <br />1,3-Butadiene was detected above 33X the Residential ISV in soil vapor samples V-2 <br />and V-4 at concentrations of 21 micrograms per cubic meter (µg/m3) and 46 µg/m3, <br />respectively. <br />Five additional VOCs (acetone, benzene, 2-propanol, propylene, and toluene) were <br />detected in the soil vapor samples at concentrations greater than or equal to the <br />laboratory reporting limits but below their respective 33X ISVs and EISVs.
