Case Narrative

The analyses for Dioxin and Furans were performed at ALS Laboratory Group in Burlington, 

Canada. See the attached report for the results.

Batch 40899, Herbicides, MS/MSD samples were not analyzed due to limited sample volume. 

A LCS and LCSD were analyzed and reported for this analytical batch.

Batch 40927, Pesticides, MS/MSD samples were not analyzed due to limited sample volume. 

A LCS and LCSD were analyzed and reported for this analytical batch. P-flag due to 

coelution. Results were reported from the non-coeluting column.

Batch 40940, PCBs, MS/MSD samples were not analyzed due to limited sample volume. A 

LCS and LCSD were analyzed and reported for this analytical batch.

Batch 41117, Mercury, (sample 1002368-02), MS/MSD is for an unrelated sample.

Batch R86715, Volatile Organic, (sample 1002125-01), MS/MSD is for an unrelated sample.

Batch R86676, Anion, (sample 1002093-02), MS/MSD is for an unrelated sample.

Batch 40947a, Semi-Volatile, LCS/LCSD recoveries were below the control limits for 

methapyrilene (37.7 / 34.9 %) and is considered a marginal exceedence, (4 sigma) allowed by 

the SOP.

Batch 40947a, Semi-Volatile, LCS/LCSD RPDs were above the control limits for Kepone, NNitrosopyrrolidien and Pyridine. The individual recoveries were with in control.

Batch 40947a, Semi-Volatile, LCS/LCSD recoveries were above the control limits for 2,4-

Dimethylaniline and 4,4'methylenebis(2-chloroaniline). The associated samples were ND for 

these compounds. LCS/LCSD RPDs were above the control limits for several compounds.

Case Narrative

The analyses for Dioxin and Furans were performed at ALS Laboratory Group in Burlington, 

Canada. See the attached report for the results.

Batch R89836, Anions by SW-9056, (sample 1004467-01), MS/MSD is an unrelated sample.

Batch 42419, Semi-Volatile, MS/MSD samples were not analyzed due to limited sample 

volume. A LCS and LCSD were analyzed and reported for this analytical batch.

COMMENTS: PCDD/F by EPA 1613B

There are some positive concentrations and estimated maximum values in the method blank a result of carryover from a prior

analyrical run. However, the absence of concentrations in the sample for a number of targets demonstrates the lack of 

positive bias for the sample run. No negative impact to overall data quality is expected

Case Narrative

The analyses for Dioxin and Furans were performed at ALS Laboratory Group in Burlington, 

Canada. See the attached report for the results.

Batch 43214, Metals, (sample Underflow Delisting-05), MS/MSD recoveries were outside the 

control limits for Mn. 

Batch 43214, Mercury, (sample 1005586-01), MS/MSD is for an unrelated sample. 

Batch 43214, Lithium, (sample Underflow Delisting-05), MS recovery was outside the control 

limits.

Batch 43100, Semi-Volatile, MS/MSD samples were not analyzed due to limited sample 

volume. A LCS and LCSD were analyzed and reported for this analytical batch.

Batch 43100, Semi-Volatile, LCS/LCSD RPDs were above the control limits for 2-

Methylphenol and Pyridine. The individual recoveries were within control.

Batch R91585, Volatile Organic, (sample 1005788-04), MS/MSD is for an unrelated sample.

COMMENTS: PCDD/F by EPA Method 1613B

There are positive target values detected in the method blank due to carryover from the preceding analysis of a standard solution.

However, the detected values are lower than the calibrated range and the impacted targets have not been detected in the sample

demonstrating an absence of bias due to laboratory background. No negative imact to overall data quality is expected.
