Ms. Moore:
In regard to NOV 2022-TX-0001 for Ridge View Community (permit
#NC0060283) for November 2021. Ridge View has taken these steps:
While lowering the chlorine dosage to pass the Toxicity Ridge View
exceeded their Fecal Coliform limit on 11/09/21. The Toxicity also failed.
Ridge View will continue sampling until they isolate and eliminate the toxin.
Additionally the Operator met the local State inspectorxinda Wiggs on site
to discuss options for resolving the issue. In December the system sampled a
second Toxicity (process control) above chlorine contact to isolate the issue
further. It also failed.At collection the chlorine was sampled from this
toxicity sample container with a result of 16 ug/L (parts per billion) or less
by the Operator. Upon delivery to the lab Kelley(ETS) found no chlorine
residual. Jim (ETS) found an oxidizer present after 24 hours. This has been
the case since August 2021. The location of this sampling and Novembers
regular scheduled Toxicity proves the oxidant is not added by the Operator
or the Owner.
Another letter has been delivered to the tenants recommending a 10% bleach
cleaning solution only. Interviews have begun with about 20% of tenants.
Please allow us time and resources to remedy this problem in lieu of a
possible fine. Your understanding in this matter is greatly appreciated. If I
can be of further assistance please do not hesitate to call.
Sincerely,
� 6VL
