County consultants map well capture zones, urge land‑use steps to protect drinking water
Summary
Presenters told the board that pump tests and monitoring identify recharge areas for community wells and recommended land‑use measures and homeowner outreach to protect those zones from contamination and unsuited development.
Presenter briefed the board on the county's drinking‑water supply and three core tasks to sustain it: identify recharge and capture zones, continue groundwater monitoring and pursue new sources where needed. He said mapping from recent pump tests shows distinct blue capture areas and that every property inside those areas contributes to the county's supply.
"This is every drop of water that falls on the ground, ultimately, makes it into your well at some point from here to here," the Presenter said while showing the capture‑zone map. He recommended mailing notices to homeowners inside the zones and discussing fertilizer and pesticide practices with the nearby golf course.
The Presenter explained the monitoring program samples for iron, manganese and volatile organic compounds and tracks water levels so the county can spot a decline or contamination migrating toward a production well before a well must be taken offline. He said earlier five‑day pump tests were used to delimit the zones of influence for clustered wells.
Board members asked for outreach and regulatory options; the discussion flagged the need to consider zoning or best‑management practices inside recharge areas, and staff said a future briefing will propose specific land‑use controls and homeowner guidance.
