The test results meet requirements of the NELAP standards except as noted in the case narrative report. All results are intended to be considered in their entirety, and ALS Environmental is not responsible for use of less than the complete report. Results apply only to the items submitted to the laboratory for analysis and individual items (samples) analyzed, as listed in the report. In accordance to the NELAC 2003 Standard, a statement on the estimated uncertainty of measurement of any quantitative analysis will be supplied upon request. For your reference, these analyses have been assigned our service request number Enclosed are the results of the sample(s) submitted to our laboratory Laboratory Results for:CNAD Dear Jeff, March 28, 2018 J1802205.

This report contains analytical results for samples designated for Tier II data deliverables, including results of QC samples analyzed from this delivery group. When appropriate to the procedure, method blank results have been reported with each analytical test. Analytical procedures performed by the lab are validated in accordance with NELAC standards. Parameters that are included in the NELAC Fields of Testing but are not included in the lab’s NELAC accreditation are identified in the discussion of each analytical procedure. Sample Receipt 41 water samples were received for analysis at ALS Environmental on 3/28/18. The samples were received in good condition and consistent with the accompanying chain of custody form. Samples are refrigerated at <6°C upon receipt at the lab except for aqueous samples designated for metals analyses, which are stored at room temperature. Volatile Organic Analyses: Method 8260B: The control criterion was exceeded for following analyte in Laboratory Control Sample Duplicate (LCSD) JQ1802416-04: Trichloroethane. Spike recovery was within +/-30%. The sample data is not significantly affected. No further corrective action was appropriate. Method 8260B: The control criterion was exceeded for one or more analytes in Laboratory Control Sample (LCS) JQ1802416-03 and Laboratory Control Sample Duplicate (LCSD) JQ1802416-04. The analytes in question were not detected in the associated field samples. The sample data is not significantly affected. No further corrective action was appropriate. Method 8260B: The control criterion was exceeded for one or more analytes in Laboratory Control Sample (LCS) JQ1802459-03. The analytes in question were not detected in the associated field samples. The sample data is not significantly affected. No further corrective action was appropriate. Method 8260B: The control criteria were exceeded for the following surrogate in samples J1802205-012 and J1802205-036 due to suspected matrix interferences: Dibromofluoromethane. No further corrective action was appropriate. Metals Analyses: No significant data anomalies were noted with this analysis. General Chemistry Analyses: Method 300.0/9056: The reporting limit is elevated for analyte(s) analyzed by IC in J1802205 (-023, -024). These sample(s) had high conductivity which precludes their analysis without prior dilution via this technique. Subcontracted Analytical Parameters: An aliquot of the samples were delivered to ENCO in Jacksonville, FL for RSK-175 determination. 9143 Philips Highway, Suite 200, Jacksonville, FL 32256 |

See case narrative. # The control limit criteria are not applicable. See case narrative. B The analyte was found in the associated method blank at a level that is significant relative to the sample result. E The result is an estimated amount because the value exceeded the instrument calibration range. J The result is an estimated concentration that is less than the MRL but greater than or equal to the MDL. U The compound was analyzed for, but was not detected (“Non-detect”) at or above the MRL/MDL. Z Too many colonies were present (TNTC). The numeric value represents the filtration volume. i The MRL/MDL has been elevated due to matrix interference. X See case narrative. METALS DATA *The result is an outlier. See case narrative. # The control limit criteria are not applicable. See case narrative. J The result is an estimated concentration that is less than the MRL but greater than or equal to the MDL. E The reported value is estimated because of the presence of matrix interference. M The duplicate injection precision was not met. N The Matrix Spike sample recovery is not within control limits. See case narrative. S The result was determined by Method of Standard Additions (MSA). U The compound was analyzed for, but was not detected (“Non-detect”) at or above the MRL/MDL. W The post-digestion spike for furnace AA analysis is out of control limits, while sample absorbance is less than 50% of spike absorbance. i The MRL/MDL has been elevated due to matrix interference. X See case narrative. + The correlation coefficient for the MSA is less than 0.995. ORGANIC DATA *The result is an outlier. See case narrative. # The control limit criteria are not applicable. See case narrative. A The tentatively identified compound is a suspected aldol-condensation product. B The analyte was found in the associated method blank at a level that is significant relative to the sample result. C The analyte was qualitatively confirmed using GC/MS techniques, pattern recognition, or by comparing to historical data. D The reported result is from a dilution. E The result is an estimated amount because the value exceeded the instrument calibration range. J The result is an estimated concentration that is less than the MRL but greater than or equal to the MDL. N The result is presumptive. The analyte was tentatively identified, but a confirmation analysis was not performed. P The GC or HPLC confirmation criteria were exceeded. The relative percent difference is greater than 40% between the two analytical results (25% for CLP Pesticides) U The compound was analyzed for, but was not detected (“Non-detect”) at or above the MRL/MDL. i The MRL/MDL has been elevated due to a chromatographic interference. X See case narrative. PETROLEUM HYDROCARBON SPECIFIC F The chromatographic fingerprint of the sample matches the elution pattern of the calibration standard. L The chromatographic fingerprint of the sample resembles a petroleum product, but the elution pattern indicates the presence of a greater amount of lighter molecular weight constituents than the calibration standard. H The chromatographic fingerprint of the sample resembles a petroleum product, but the elution pattern indicates the presence of a greater amount of heavier molecular weight constituents than the calibration standard. O The chromatographic fingerprint of the sample resembles an oil, but does not match the calibration standard. Page 24 of 168 Y The chromatographic fingerprint of the sample resembles a petroleum product eluting in approximately the correct carbon range, but the elution pattern does not match the calibration standard. Z The chromatographic fingerprint does not resemble a petroleum product.
