Re: Effluent Sampling
25 South Circle Drive
Chapel Hill, North Carolina
Dear Mr. Hutto:
NCG-55 IU7
On June 9, 2022, Conner Consulting collected effluent samples as required on your DWQ permit
at 25 South Circle Drive, Chapel Hill, North Carolina. The results are as follows:
Flow: <:: 200 gpd (estimated)
Total Residual Chlorine: 0.30 parts per million @ 12:05
Biochemical Oxygen Demand: 4.4 mg/l
Total Suspended Solids: 32 mg/l
Fecal Coliform: 610 CFU/100 ml.
I suggest adding chlorine tablets more frequently to reduce the fecal coliform. My field
laboratory certification is #5149. Please call with questions and comments.
Sincerely yours,
Chad Leinbach

FLAGS/NOTES AND DEFINITIONS
B The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
] The reported value is between the laboratory method detection limit (MDL) and the laboratory method
reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable.
U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
E The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.
PQL PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL.
N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater
confidence) to make a "tentative identification".
P Greater than 25% concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
[CALC] Calculated analyte - MDL/MRL reported to the highest reporting limit of the component analyses,
