Thank you for allowing Barium Springs Home for Children the opportunity to respond to the
Notice of Violation issued April 5, 2019 by the Division of Water Resources. You will find
below our response to the following infractions: Effluent BOD daily maximum exceeded 2-4-
2019; Effluent BOD monthly average exceeded; and effluent NH3 -N monthly average exceeded.
During the course of the first week of February, the operator on site noticed that the valve on the
bell in the Imhoff tank appeared to be closed, but in actuality, was slightly opened, allowing
constant flow to go into and through the sand filters. Upon noticing this abnormality, the
operator adjusted and fixed the valve so that it would close fully and stop the flow of wastewater.
However, by the time that this issue was noted and fixed, samples had already been pulled on
February 4. This constant flow prevented any detention time in the Imhoff tank, and
consequently, both the BOD and the NH3-N were abnormally high.
As noted above, the operator was able to repair the valve that failed to fully close. This rectified
the issue of flow constantly running to the filter as it came into the Imhoff tank. In addition,
