Permit WQ0000020, Asheville Airport Fill�ater July 2019 Surface Water Analytical Results Quality Regional Operations Asheville Regional Office Dear Sir or Madam: Attached are the results from the most recent quarterly 'surface water' sampling event conducted in July 2019 at the Asheville Regional Airport near the Area I fill. The results from this sampling event are included on the GW59CCR form per permit WQ0000020, dated September 2, 2015. As this structural fill sampling event is not part of an NPDES permit, the form was slightly modified and is not signed. Area I 'surface' water samples were collected on July 1, 2019. Per DEQ letter dated April 30, 2018, DEQ requested quarterly 'surface water' sampling rather than semi-annually and the number of locations to sample were increased compared to permit WQ0000020. If you have any questions or need any clarification regarding the information provided, feel free to contact me at iohn.toel)ferCaduke-eneray.com or at 919-546-7863 at your convenience.

MOL- Adjusted Method Detection Limit. Pace Anal�(ll 1, "Ices, LLC fy���86h�e. Suite 100 Huntersville, NC 28078 (704)875-9092 PQL- Practical Quantitalion Limit. RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and bias for a specific analyte in a specific matrix. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean -Up U - Indicates the compound was analyzed for, but not detected. Acid preservation may not be appropriate for 2 Chloroethylvinyl ether. A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA Method 8260.
