Dear Mr. Vinson,
After reviewing; the events of what transpired the week of April I Pit, we were not able to
determine the exact cause, or the perpetrator, of the missing conductivity, dissolved oxygen, pH
and water temperature data.
Grab samples for pH and Conductivity are collected daily and analyzed with a calibrated
benchtop meter within the 15 minute hold time. The DO and Temperature are analyzed daily
using a calibrated handheld meter at the sampling points. These results are recorded on a single
bench sheet located in the lab. The bench sheet is checked daily by the lab analyst and weekly by
the lab supervisor and lab manager. The bench sheets are stored and used at a later date to
complete the DMR.
This particular week's samples were collected, analyzed and in compliance. However, the
weekly bench sheet that contained the data was lost. Lab personnel searched the entire lab, file
folders, etc., but were unable to locate the bench sheet for DMR entry.
Inline monitoring for process control is also conducted daily for DO, Temperature, and pH.
These results are recorded by the plant operator on a different sheet. While these are not certified
they do represent a very accurate indication of actual certified results. The following are a list of
the inline monitoring results for that week:

We have since prepared an online spreadsheet to serve as a virtual back-up of all the data we
record at the plant, including the aforementioned parameters, should we lose our physical bench
sheets again. These data parameters are recorded DAILY by the lab analyst.
Please note that DEO Raleigh Regional office was notified by nhone as soon as this issued was
noticed. Please also note that Franklin County has consistently been in compliance for these field
parameters and we have not received any toxic influent loads.
If you have any further question, please contact our office at 919-556-6177.
