The letter states that the fieldwork <br /> includes advancing CPT-10 if hole clearance to eight feet bsg is successful. <br /> Vicki McCartney,Senior REHS <br /> San Joaquin County <br /> Environmental Health Department <br /> 600 East Main Street <br /> Stockton,California 95202 <br /> Phone: (209)468-9852 <br /> Fax: (209)468-3433 <br /> Email: vmccartney Isjcehd.com <br /> From: Eli Scott [mailto:eli_scott@hfa.com] <br /> Sent: Friday, December 17, 2010 4:21 PM <br /> To: Vicki McCartney [EH] <br /> Subject: Re: 139 South Center Street, Stockton, SJCEHD Case #1039: Field work deadline extension and <br /> CPT logs <br /> Hi Vicki, <br /> It was great meeting you too. The original scope of work did include four CPT borings, <br /> unfortunately we were not able to clear more than two holes to 8 fbg in the location indicated on <br /> the attached plot plan after 6 attempts. With only two holes cleared, we are looking to prioritize <br /> the collection of soil and groundwater samples rather than CPT data from that location. .When we <br /> remobilize I can have the drill crew attempt to clear an additional hole for CPT, but with the <br /> amount of debris we have encountered thus far in the subsurface, the chances that we.successfully <br /> get to 8 fbg are very low. So far to date we have dedicated 5 days to hole clearance using both air <br /> knife and hand auger techniques. <br /> Thanks, <br /> Eli Scott <br /> Associate Environmental Scientist <br /> Holguin, Fahan &Associates, Inc. <br /> 5627 Stoneridge Drive, Suite 320 <br /> Pleasanton, CA 94588 <br /> Office: (925)397-0997 x403 <br /> Cell: (805)766-3770 <br /> Fax: (925)737-0065 <br /> 12/21/2010 <br />
