<br />San Joaquin County Environmental Health Department (EHD) has reviewed the letter dated
<br />December 6, 2005, documenting discussions on November 10, 2005, between Sara Lee Bakery
<br />Group, Inc., represented by Philip Environmental Services Corporation (PSC) and ETIC
<br />Engineering (ETIC), and EHD. PSC's letter succinctly summarizes the main points presented at
<br />this meeting and requests changes for future groundwater sampling at this site.
<br />EHD concurs with recommendations to continue measuring depth -to -water and total depths for
<br />all wells on a quarterly basis to determine groundwater gradient; discontinue sampling monitoring
<br />wells MW -3 and MW -6 based on well locations and non -detect results reported historically for
<br />these wells; and annual collection in July of groundwater samples from MW -10.
<br />EHD recommends that you continue to build upon the site conceptual model submitted to EHD in
<br />April 2003; and revise the fate and transport model included in Quarterly Groundwater
<br />Monitoring Report, October 2004 dated August 19, 2005, with site specific data, where possible,
<br />and propose a method for testing this model.
<br />If you have any questions regarding this letter, please contact Vicki McCartney at (209) 468-3456
<br />or by electronic mail at vmccartney@sjcehd.com.
