Assistance Type: OTHER WATER QUALITY - Arsenic RAA
Reasons: Arsenic
Details: Talked to Warren about quarterly Arsenic sample results consistently hovering near the MCL and due to duration of questionable arsenic level it was now important to find a long term resolution.
He explained intent to change the medium in one filter to E33 ferric oxide, advertised to help lower arsenic, before collecting sample due this quarter-before end of March 2021 and hoped result would be significantly below the MCL. The E33 medium had yet to be purchased and Warren hoped a PE from DWS would agree with its use for this purpose and grant plan review approval if needed in time to get all needed work done by end of March.
I also advised that public notice would need to be posted as the RAA for the last year exceeded the MCL. I offered to communicate that to Leeann working in the GMs office.
