Whether a new home can legally get its own water here — the sub-state groundwater regime, from Virginia’s water agency.
The aquifer here is over-appropriated and declining. A domestic well is usually still permit-exempt, but long-term supply is a genuine risk.
Household wells are exempt from the groundwater withdrawal permit even inside a Groundwater Management Area, but a private well in a GWMA must be registered with DEQ within 30 days (Va. Code 62.1-258); a permit is triggered only at 300,000 gal/month.
Limit: < 300,000 gal/month (no withdrawal permit)
Virginia DEQ — Ground Water Withdrawal Permitting ↗DEQ has imposed mandatory withdrawal reductions on large Coastal Plain permittees because permitted demand exceeds sustainable aquifer yield (declining heads, land subsidence, saltwater-intrusion risk). Household wells (<300,000 gal/mo) are exempt but must be registered. The I-95-west counties (Fairfax, Chesterfield, Hanover, Henrico, Prince William, Spotsylvania, Stafford, Caroline) are included only east of I-95.

Groundwater rules change and basin boundaries follow the aquifer, not the county line — confirm current well and appropriation rules with the Virginia state water agency before you buy or drill.Groundwater governance as of Jul 2026, cited to each administering agency.
