Hexane was used because it was most representative of the lower carbon range organics. 2=System pemlitted under ATC number N4878-1-1. Source test for air board. Extracted groundwater being held in onsite holding tank. System shutdown following source test. 3=System started for 24-hour collection of vapor PAH samples. 4=System shut doom following completion of vapor PAH sample collection. PAH results outside of ATC limits(no detectable PAHs in influent vapor stream);altemate ATC needed to operate. 5=Approximately 5,840 gallons of groundwater stored in holding tank discharged to sanitary sewer. 6=ATC Number N4878-1-2 issued 7120/2004.System restarted. 7=Source test for air board. System shut dawn following source test due to on-site excavation activities. 8=Samples collected from wastewater treatment system.Carbon changeout needed. 9=System shut down following completion of vapor PAH sample collection. 10=System nonoperational since 5/2005.No sampling and no discharge activities occurred. 11 =System effluent sampled on 7/6/2005 following startup. 12=Start-up on fresh GAC \\US1345-F031workgmup\1857\ac6ve\185750217\05_report_deliv\dwgs_design\tables\O&M Tables 2016\Paroel 2A OM Tables 1Q16.xlsx Page 1 of 1
