Case Narrative Project Name: Mayflower, AR Pipeline Incident LLI Group #: 407340 General Comments: See the Laboratory Sample Analysis Record section of the Analysis Report for the method references. All QC met criteria unless otherwise noted in an Analysis Specific Comment below. Refer to the QC Summary for specific values and acceptance criteria. Project specific QC samples are not included in this data set Matrix QC may not be reported if site-specific QC samples were not submitted. In these situations, to demonstrate precision and accuracy at a batch level, a LCS/LCSD was performed, unless otherwise specified in the method. Surrogate recoveries (if applicable) which are outside of the QC window are confirmed unless attributed to a dilution or otherwise noted in an Analysis Specific Comment below. The samples were received at the appropriate temperature and in accordance with the chain of custody unless otherwise noted. Analysis Specific Comments: SW-846 8260B 25mL purge, GC/MS Volatiles Batch #: I320AA (Sample number(s): 742340, 742342, 742344 UNSPK: P42305) The recovery(ies) for the following analyte(s) in the MS and/or MSD was outside the acceptance window: Hexachlorobutadiene, Methyl Tertiary Butyl Ether The relative percent difference(s) for the following analyte(s) in the MS/MSD were outside outside acceptance windows: Hexachlorobutadiene SW-846 8270C SIM, GC/MS Semivolatiles Batch #: 3209WAA026 (Sample number(s): 742340, 742342 UNSPK: P42306) The recovery(ies) for the following analyte(s) in the MS and/or MSD was outside the acceptance window: Benzo(a)pyrene The recovery(ies) for one or more surrogates were outside of the QC window for sample(s) 742340, 742342 Sample #s: 742340, 742342 The recovery for the sample surrogate(s) is outside the QC acceptance limits as noted on the QC Summary. The client was contacted and the data reported. SW-846 600B, Metals Batch #: 3208848002 (Sample number(s): 742340-742343 UNSPK: P42305 BKG: P42305) The recovery(ies) for the following analyte(s) in the MS and/or MSD was outside the acceptance window: Magnesium, Lead SW-846 600B, Metals Dissolved Batch #: 3208848002 (Sample number(s): 742340-742343 UNSPK: P42305 BKG: P42305) The recovery(ies) for the following analyte(s) in the MS and/or MSD was outside the acceptance window: Lead v.8.8 7/30/203 :08:07PM Page 3 of 26

Explanation of Symbols and Abbreviations The following defines common symbols and abbreviations used in reporting technical data: RL Reporting Limit BMQL Below Minimum Quantitation Level N.D. none detected MPN Most Probable Number TNTC Too Numerous To Count CP Units cobalt-chloroplatinate units IU International Units NTU nephelometric turbidity units umhos/cm micromhos/cm ng nanogram(s) C degrees Celsius F degrees Fahrenheit meq milliequivalents lb. pound(s) g gram(s) kg kilogram(s) µg microgram(s) mg milligram(s) ml milliliter(s) L liter(s) m3 cubic meter(s) µl microliter(s) pg/l picogram/liter ppm ppb < less than - The number following the sign is the limit of quantitation, the smallest amount of analyte which can be reliably determined using this specific test. > greater than parts per million - One ppm is equivalent to one milligram per kilogram (mg/kg), or one gram per million grams. For aqueous liquids, ppm is usually taken to be equivalent to milligrams per liter (), because one liter of water has a weight very close to a kilogram. For gases or vapors, one ppm is equivalent to one microliter per liter of gas. parts per billion Dry weight Results printed under this heading have been adjusted for moisture content. This increases the analyte weight basis concentration to approximate the value present in a similar sample without moisture. All other results are reported on an as-received basis. Data Qualifiers: C result confirmed by reanalysis. J - estimated value The result is the Detection Limit (MDL) and < the Limit of Quantitation (LOQ). U.S. EPA CLP Data Qualifiers: Organic Qualifiers Inorganic Qualifiers A TIC is a possible aldol-condensation product B Value is <CRDL, but IDL B Analyte was also detected in the blank E Estimated due to interference C Pesticide result confirmed by GC/MS M Duplicate injection precision not met D Compound quantitated on a diluted sample N Spike sample not within control limits E Concentration exceeds the calibration range of S of standard additions (MSA) used the instrument for calculation N Presumptive evidence of a compound (TICs only) U Compound was not detected P Concentration difference between primary and W Post digestion spike out of control limits confirmation columns >25% * Duplicate analysis not within control limits U Compound was not detected + Correlation coefficient for MSA <0.995 X,Y,Z Defined in case narrative Analytical test results meet all requirements of NELAC unless otherwise noted under the individual analysis. Measurement uncertainty values, as applicable, are available upon request. Tests results relate only to the sample tested. Clients should be aware that a critical step in a chemical or microbiological analysis is the collection of the sample. Unless the sample analyzed is truly representative of the bulk of material involved, the test results will be meaningless. If you have questions regarding the proper techniques of collecting samples, please contact us. We cannot be held responsible for sample integrity, however, unless sampling has been performed by a member of our staff.

Parameters listed in the 40 CFR part 36 Table II as analyze immediately are not performed within 5 minutes.
