Can you drill a well without a permit in Pennsylvania?

Exempt — no permit or water right. Pennsylvania does not permit private water wells (reasonable-use doctrine). Large withdrawals may need DRBC approval (>10,000 gpd inside the SE PA Ground Water Protected Area) or SRBC approval (>=100,000 gpd), but a household well is far below every threshold.
