Lake Arrowhead CSD: recent PFOA readings below California threshold; consumption uptick traced to leak
Summary
General Manager Catherine Cerri reported a PFOA result of 7.1 and a quarterly average of 8.1—both below the California value of 10—and said a 5% consumption increase reflected a large leak rather than higher retail use.
At the executive committee meeting, General Manager Catherine Cerri said new drinking-water testing returned a PFOA result of 7.1 with a quarterly average of 8.1, both reported as below California's regulatory level of 10.
She also said the Operations Manager's monthly report will show a 5% increase in water consumption; Cerri attributed that rise to a large leak rather than higher usage by customers. The district continues to track participation in the PFAS Water Filter Rebate Program; current participation counts were summarized but not specified in the minutes.
Cerri reaffirmed that recent system improvements are helping the District meet the requirements of the Cease-and-Desist Order (CDO).
