Notes: 1 =System permitted under ATC No.N-4878-1-1. Source lest for air board. Extracted groundwater being held in onsite holding tank. System shut down following source test. 2 =Source test for air board. System shut down following source test due to on-site excavation activities. 3=Wastewater not discharge to sanitary sewer,stored in onsite holding tank. 4 =Repeat analysis for TPHg yielded inconsistent results,the highest value detected is reported as an estimate. 5 = System shut down following completion of vapor PAH sample collection. 6 =Hydrocarbons reported as TPHo do not exhibit a typical Motor Oil chromatographic pattern. 7=No sampling due to system not operating.No discharge past 6/3/2005 until 7/6/2005. 8=pH sample collected on 10/20/2005 due to exceedance of holding time on pH sample collected on 10/18/2005. 9 =System offline from 12/7106 to 5/30/07 for construction.System restarted on 5/21/07and sampled on 5/31/07. 10 =pH sample tested using standard method SM-4500-HB out of 15 minute holding time. 11 =Sample analyzed using a bottle that contained a headspace bubble greater than 1/4 inch in diameter. 12 =Matrix/Spike Duplicate results for the analyte toluene were affected by the analyte concentrations already present in the un-spiked sample. 13 =Repeated analysis yielded inconsistent results for the analyte ethylbenzene. The concentrations appear to vary between bottles. The highest valid results are reported. 14 =Matrix/S ike Duplicate results for the analyte benzene were affected by the anal)Ie concentrations already present in the un-spiked sample. \\US1345-F031workgmup\1857\acfvekl B5750217\05_repor_delivldwgs_design\tables\O&M Tables 201MCopy of Parcel 2A OM Tables 1016 xlsx Page 2 of 3
