Mr. Shaffer, thanks for the phone call this morning. Whereas Ukon Water did in fact find the majority of the animal carcass intact inside the original hydrant at 520 S. Center Street on Saturda
to hydrant has been isolated since last week, we would accept the samples taken on 5/23/2024 as the first set of clean samples. As we discussed, if you take a further 6 investigative samples
second set of clean samples after the carcass was discovered. Assuming they all pass, this would meet the requirements to lift the boil order.
Thank you for your assistance and understanding during this difficult situation.

We at the Division of Drinking Water wanted to clarify our approach and requirements for how we should proceed, as this is something of a unique situation. Whereas we have a known con
animal carcass in the distribution system, the process for resolving the situation falls outside of the normal RTCR Routine/Repeat protocol. An actual animal carcass represents health risks
bacteriological test. Coliform and E. coli bacteria are an indicator of possible contamination, and a great tool for investigation, but in this case we have a known contamination source which
has been removed from the distribution system. The samples taken to this point have been useful for the investigation of the incident, but do not alone indicate the elimination of the contam
"find and fix" the root cause, bacteriological samples are a tool in that process, but the goal is to eliminate the source of the contamination.
Considering these factors, we are requiring the following steps as we work toward a resolution:
1. Implementation of a plan to recover at least the majority of the animal carcass. It is our understanding that only soft tissue has been recovered at this point, and not more substantial part
need verification (photos, etc.) that the majority of the carcass has been recovered in order to move forward. Continued flushing, bacti sampling and monitoring of chlorine residuals are all
