There was no <br /> mention of collecting a crawl space air sample. I have discussed this matter with Nuel Henderson and we both <br /> agree that indoor air, ambient air and at least one crawl space sample should be collected since it has been over <br /> a year since the vapor mitigation system began operating at the Weldon Church site at 104 West Beverly Place in <br /> Tracy. I definitely would like to be present when these air samples are collected. Thank you. <br /> Vicki McCartney, Senior REHS <br /> San Joaquin County <br /> Environmental Health Department <br /> 1868 East Hazelton Avenue <br /> Stockton, California 95205 <br /> Phone: (209) 468-9852 <br /> Email: vmccartney(c-Dsicehd.com <br /> From: Brian Millman [mailto:bmillman@advgeoenv.com] <br /> Sent: Thursday, August 01, 2013 11:52 AM <br /> To: Vicki McCartney [EH] <br /> Subject: Weldon Church Crawl Space Air Sampling <br /> Vicki, <br /> Good afternoon Vicki, I would like to schedule a crawl space air sampling event at 104 West <br /> Beverly Place, Tracy, CA. The vapor mitigation system has now been operating for over a year <br /> (operation began in June 2012). The original plan was to collect a crawl space air sample after 6 <br /> months of operation and/or 1 year of operation; a sample wasn't collected after 6 months due to <br /> budget constraints. <br /> I have not scheduled the event with the property owner yet, but I did procure the equipment so it <br /> can be performed sometime next week. Do you want to be onsite for the sampling event/when I <br /> place the canister in the crawl space? If you do I will contact you either tomorrow or Monday to let <br /> you know what day it will be; if not, I will coordinate with the property and get it done sometime <br /> next week (but I will still contact you and tell you what day we will be placing the canister). <br /> Thanks, <br /> Brian W.
