NC0006254_Groundwater Monitoring Report July 2020_20200722
PO Box 604 ▪ Fletcher, NC 28732 ▪ PH: 828-667-5001 ▪ Cell: 828-508-4510 July 22, 2020 Mr. Brett Laverty NCDEQ Division of Water Resources Asheville Regional Office 2090 US Highway 70 Swannanoa, NC 28778 RE: Groundwater Analytical Results – July 2020 Blue Ridge Tissue Corporation 1427 Yadkin River Road Patterson, North Carolina Mr. Laverty: On July 7, 2020, Singleton Environmental, Inc. (SEI) visited the Blue Ridge Tissue site located at 1427 Yadkin River Road in Patterson, North Carolina, to collect groundwater samples from monitoring wells MW-1, MW-2, MW-3, MW-4, MW-6, MW-7 and MW-8. The depth to groundwater in the monitoring wells ranged from 5.28 feet in MW-4 to 49.09 feet in MW-2. Refer to Table 1 for all monitoring well groundwater depths and Figure 1 for all monitoring well locations. All groundwater samples, with the exception of MW-2, were collected using a peristaltic pump connected to a Horiba U52-2 water quality meter with a flow through cell to collect groundwater parameters (temperature, pH, specific conductivity, dissolved oxygen, ORP, and turbidity). Groundwater sample MW-2 was collected using a bailer once three well volumes were removed. Groundwater from the same bail as the sample was also poured into the flow cell to collect the approximate parameters. The groundwater samples were submitted on ice to Pace Analytical for the analysis of barium, iron, manganese, ammonia, TKN, nitrogen, nitrite and nitrate. MW-2 was also analyzed for total dissolved solids (TDS) using EPA Method SM 2540C. The groundwater parameters for all samples are outlined in Table 2. The laboratory analysis of groundwater samples MW-1 detected levels of iron and manganese above the NCAC 2L groundwater standards. The laboratory analysis of MW-2 detected levels of arsenic, barium, iron, manganese and ammonia above the NCAC 2L groundwater standards. The laboratory analysis of groundwater samples MW-3 detected levels of iron, manganese and ammonia above the NCAC 2L groundwater standards. The laboratory analysis of groundwater samples MW-4 detected levels of iron and manganese above the NCAC 2L groundwater standards. Laboratory analysis of groundwater samples MW-6, MW-7 and MW-8 did not detect any compounds exceeding the NCAC 2L groundwater standards. The analytical results are shown on attached Table 2 and the attached laboratory data sheets. During the April 2017 groundwater sampling event, AECOM reported a possible sheen on the groundwater in monitoring well MW-4. During the July 2020 event a sheen was not observed; therefore, a volatile organic compound (VOC) analysis was not performed on the sample. Singleton Environmental, Inc. Singleton Environmental, Inc. The compound levels detected in the groundwater analysis for the July 2020 sampling event were comparable to the March 2020 event. Singleton Environmental, Inc. recommends sampling the monitoring wells again in October 2020. If you have any questions you can reach me at (828) 508-4510. Sincerely, Chris Singleton, P.G.

ND - Not Detected at or above adjusted reporting limit. TNTC - Too Numerous To Count J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL - Adjusted Method Detection Limit. PQL - Practical Quantitation 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. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for each analyte is a combined concentration. Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes. TNI - The NELAC Institute. ANALYTE QUALIFIERS The same analyte was detected in an associated blank at a concentration above 1/2 the reporting limit but below the laboratory reporting limit.BC Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.M1 REPORT OF LABORATORY ANALYSIS This report shall not be reproduced, except in full, without the written consent of Pace Analytical Services, LLC.Date: 08/10/2020 09:20 AM Pace Analytical Services, LLC 2225 Riverside Dr. Asheville, NC 28804 (828)254-7176 Page 20 of 24 #=CR# QUALITY CONTROL DATA CROSS REFERENCE TABLE Pace Project No.: Project: 92485972 BLUE RIDGE TISSUE 7-14-2020 Lab ID Sample ID QC Batch Method QC Batch Analytical Method Analytical Batch 92485972001 553603 553760MW-1 EPA 200.7 Rev 4.4 1994 EPA 200.7 Rev 4.4 1994 92485972002 553603 553760MW-2 EPA 200.7 Rev 4.4 1994 EPA 200.7 Rev 4.4 1994 92485972003 553926 553955MW-3 EPA 200.7 Rev 4.4 1994 EPA 200.7 Rev 4.4 1994 92485972004 553926 553955MW-4 EPA 200.7 Rev 4.4 1994 EPA 200.7 Rev 4.4 1994 92485972005 553926 553955MW-6 EPA 200.7 Rev 4.4 1994 EPA 200.7 Rev 4.4 1994 92485972006 553926 553955MW-7 EPA 200.7 Rev 4.4 1994 EPA 200.7 Rev 4.4 1994 92485972007 553926 553955MW-8 EPA 200.7 Rev 4.4 1994 EPA 200.7 Rev 4.4 1994 92485972002 554228MW-2 SM 2540C-2011 92485972001 553968MW-1 EPA 350.1 Rev 2.0 1993 92485972002 553968MW-2 EPA 350.1 Rev 2.0 1993 92485972003 553968MW-3 EPA 350.1 Rev 2.0 1993 92485972004 553968MW-4 EPA 350.1 Rev 2.0 1993 92485972005 553968MW-6 EPA 350.1 Rev 2.0 1993 92485972006 553968MW-7 EPA 350.1 Rev 2.0 1993 92485972007 553969MW-8 EPA 350.1 Rev 2.0 1993 92485972001 554559 554589MW-1 EPA 351.2 Rev 2.0 1993 EPA 351.2 Rev 2.0 1993 92485972002 554559 554589MW-2 EPA 351.2 Rev 2.0 1993 EPA 351.2 Rev 2.0 1993 92485972003 554559 554589MW-3 EPA 351.2 Rev 2.0 1993 EPA 351.2 Rev 2.0 1993 92485972004 554559 554589MW-4 EPA 351.2 Rev 2.0 1993 EPA 351.2 Rev 2.0 1993 92485972005 554559 554589MW-6 EPA 351.2 Rev 2.0 1993 EPA 351.2 Rev 2.0 1993 92485972006 554559 554589MW-7 EPA 351.2 Rev 2.0 1993 EPA 351.2 Rev 2.0 1993 92485972007 554559 554589MW-8 EPA 351.2 Rev 2.0 1993 EPA 351.2 Rev 2.0 1993 92485972001 553327MW-1 EPA 353.2 Rev 2.0 1993 92485972002 553327MW-2 EPA 353.2 Rev 2.0 1993 92485972003 553327MW-3 EPA 353.2 Rev 2.0 1993 92485972004 553327MW-4 EPA 353.2 Rev 2.0 1993 92485972005 553327MW-6 EPA 353.2 Rev 2.0 1993 92485972006 553327MW-7 EPA 353.2 Rev 2.0 1993 92485972007 553327MW-8 EPA 353.2 Rev 2.0 1993 REPORT OF LABORATORY ANALYSIS This report shall not be reproduced, except in full, without the written consent of Pace Analytical Services, LLC.Date: 08/10/2020 09:20 AM Pace Analytical Services, LLC 2225 Riverside Dr. Asheville, NC 28804 (828)254-7176 Page 21 of 24 Page 22 of 24 Page 23 of 24 Page 24 of 24
