Summary

Deputy Director James Ritter told the Planning Commission that Marley Run is currently the only county water system requiring arsenic removal filters; other systems are monitored against a three‑year running average standard.

During the comprehensive plan discussion, a commissioner asked about arsenic removal across county water systems. James Ritter, deputy director for enterprise fund operations, said Marley Run is the only system that currently requires arsenic removal filters.

"Marley Run is our only water system that requires arsenic removal filters," Ritter said. He added that other systems are monitored and must remain under a running three‑year average of 10 micrograms per liter; if systems exceed that threshold, treatment would be required.

The consultant's draft includes a "quality of drinking water" section noting the decommissioning of the Dares Beach well and the installation of a new well at Chesapeake Heights; the draft also referenced an arsenic filter at Marley Run. Commissioners asked staff how other systems are monitored and how design changes would account for future growth at facilities such as Northern High School.
