This letter is in response to the Notice of Violation that we received on July 17th, 2017. At this point the Town is
unsure why or how the cadmium violation occurred. Siler City Wastewater Staff has collected samples
throughout the collections system, including in and around industries and pump stations, in an effort to locate any
observable source of cadmium. Presently, nine different locations have been sampled. However, no conclusions
or leads have been identified as to where the resulting violation originated.

As you are aware, cadmium will be difficult to trace and isolate due to the inconsistency of its appearance in our
samples. Please advise if you have any thoughts of what other methods can and should be employed to address
this situation. Additionally, please advise if you have any further questions or concerns as we continue to make
efforts to resolve this matter.
