Summary
The commission accepted Part 1 (water resources) of the county's comprehensive plan chapter after staff outlined aquifer structure, current state and USGS data limitations, and recommendations to track groundwater appropriation and wellhead protection, especially for the shallow Columbia aquifer.
Caroline County planners presented Part 1 of the water resources chapter for the comprehensive plan and the commission voted to accept it for incorporation into the draft plan.
Staff explained that the chapter covers surface water and groundwater sources, describing the county’s aquifer sequence (including the relatively shallow Columbia aquifer in the northern part of the county and deeper confined aquifers such as Piney Point) and noted that state/USGS reporting at the county level is limited: the most detailed local groundwater-usage data staff used were from 2015, with watershed-level data available for 2020. Staff said that without a requirement for private well reporting there are large unknowns about domestic well counts and usage in the shallower Columbia aquifer.
Grundon and staff recommended implementation steps including monitoring groundwater appropriation permits, coordinating reviews of very large water users (for example, the commission discussed prior AquaCon and potential data-center requests), and working with state agencies on wellhead protection and large-user impacts. Staff emphasized that state data show the county’s aquifers in generally good condition through mid-century projections but that better domestic-well reporting would improve planning and public-health oversight.
A commissioner moved to accept the water resources chapter (Part 1); the commission approved the item on a voice vote. Staff will continue work on Part 2 (water quality) and return it for subsequent review.
