Details: DWS emailed system contacts to inform them of recent sodium results. Sodium was 125 mg/L in the ASR well sample collected on 10/6/2021 (20 mg/L is the advisory level and sodium does not have a MCL). DWS staff notified Washington County contacts of the sodium results as well.

11/17/21: System replied stating sample was collected before ending recovery at the ASR well, and is an indication of native groundwater starting to mix with treated injected water. System is recharging the well today (11/17/21), which will push this mixing zone away from the well.
