Since you now have the bore logs sent <br /> from me, please revise this statement. <br /> . 3.2.2 - Monitoring wells MW-1 through MW-3 were installed in July 1993, not August 1993. <br /> Section 4.0 <br /> • I believe Figure 10, not Figure 13, contains the Receptor Survey Map. <br /> Section 5.0 Risk Assessment -Johnson and Ettinger Model <br /> • The incremental risk from vapor intrusion to indoor air from benzene was determined to be <br /> approximately 8.8E-06 (not 8.8E-05) and the hazard quotient for vapor intrusion to indoor air was <br /> calculated to be 1.4E-02 (not 1.4E-01). <br /> • The incremental risk from vapor intrusion to indoor air for m-xylenes was determined to be <br /> approximately 1.2E-02, not 1.6EO, and the hazard quotient for vapor intrusion to indoor air was <br /> calculated to be 1.6E+00, not 1.2E-02. <br /> Please let me know if you disagree with any of the above revisions. <br /> Thank you, Jeanne. <br /> ,.
