Whether a new home can legally get its own water here — the sub-state groundwater regime, from Maryland’s water agency.
This basin is under active state management — new water use is scrutinized, though a domestic well is usually still allowed.
Individual domestic use is exempt from the Maryland water appropriation permit (COMAR 26.17.06); a well-construction permit is still required, and non-domestic/large withdrawals (>10,000 gpd) need an appropriation permit.
Limit: individual domestic use exempt from appropriation permit
Maryland MDE — Water Appropriation Permits ↗MDE delineates five Water Management Strategy Areas (Annapolis Neck, Kent Island, Indian Head, Waldorf, Ocean Pines) where declining heads or saltwater intrusion trigger heightened permit scrutiny; once an aquifer hits 80% of available drawdown no additional water-supply pumping is allowed. Individual domestic use is exempt.
