Contact Date:	12/21/2015
Contacted By:	KRUGER, SCOTT (BENTON COUNTY)
Contact Method/Location:	Office

Assistance Type:	WATER QUALITY ALERT RESPONSE
Reasons:	Nitrate N/A

Details:	SUMMARY: Quarterly nitrate sample tested at 7.2 ppm DETAILS: Tim reported that the filter on the ion-exchange unit was clogged. He noticed this because the system was not using the normal amount of salt. The filter was cleaned and Tim will draw another sample to insure the system is functioning correctly. I notified Tim that I would be removing the system from the quarterly sampling requirement as they have shown to be reliably and consistently below the MCL. ACTION NEEDED: Wait for follow-up test results, file a chemical sampling schedule change request.
