Does all monitoring data and sampling frequencies meet the requirements in Attachment A of your permit? ❑ Compliant ❑ Non -Compliant
If the facility is non -compliant, please explain in the space below the reason(s) the facility was not in compliance. Provide in your explanation the date(s) of the non-compliance and describe the corrective
action(s) taken. Attach additional sheets if necessary.
Lab Qualifiers for June 13, 2023 sample: Fecal coliform - D6, The precision between the sample and sample duplicate exceeded laboratory control limits. U2, Colonies are too numerous to count. Actual result
may be greater than reported. BOD - B2, Oxygen usage is less than 2.0 for all dilutions set. The reported value is an estimated less than value and is calculated for the dilution using the most amount of sample.
B3, The dissolved oxygen depletion of the dilution water blank exceeded 0.2 mg/L. TKN - M1, Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.
Flow meter calibrated on 6/27/2023. The previous flows were much lower before calibration.

QUALIFIERS
Project: FOREST LAKE -MONTHLY -Revised Report
Pace Project No.: 92672220
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
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 ofAcrolein 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.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TNI - The NELAC Institute.
ANALYTE QUALIFIERS
B2 Oxygen usage is less than 2.0 for all dilutions set. The reported value is an estimated less than value and is calculated
for the dilution using the most amount of sample.
B3 The dissolved oxygen depletion of the dilution water blank exceeded 0.2 mg/L.
D6 The precision between the sample and sample duplicate exceeded laboratory control limits.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.
u2 Colonies are too numerous to count. Actual result may be greater than reported.
