The Baker tank is scheduled for deliver to the site at 0700. The activated carbon is scheduled for deliver in the morning on January 29, 2002.

' Set up barricades around wells and set up table in drive-up lane. • Collect a groundwater sample from the extraction well prior to test (no purging required). • Install pump into well. ' Set up test and get started hopefully by 0900 to 0930. • Do a drum inventory of the site and collect one 4-tube composite soil sample from the drummed soil cuttings. Submit soil sample to Argon Labs for analysis of TPHg, BTEX, ' seven oxygenates, and total lead on a standard turnaround time. • Once the test has begun, John will deliver the groundwater sample collected from the extraction well to Argon for immediate analysis. Deliver soil sample too on standard ' turnaround time. John will then go to Stockton and mark Franklin for USA and return to -- Lodi to help Alex finish the pump test. t Identify the sewer discharge point to be used after the water has been remediated.
