Water Well Driller

Alabama requires a water well driller license, almost certainly through an environmental, water resources, or public health agency rather than a contractor board. Specific requirements weren't individually verified - NGWA'S state directory is the fastest way to find the right agency. Expect a written exam (often NGWA's), a separate pump installer license if you do pump work, and per-well permits on top of your license.

What applies instead: No well-driller-specific reciprocity was verified for Alabama, and industry sources state plainly that a well driller's license in one state does not automatically grant permission to drill in another. Important: this dataset documents Alabama'S contractor-board reciprocity separately - that governs construction trades, not well drilling, which sits with a different agency.

Note: Well driller licensing for Alabama needs a dedicated verification pass against the state's own environmental/water agency - start from NGWA's state resources directory.

Alaska requires a water well driller license, almost certainly through an environmental, water resources, or public health agency rather than a contractor board. Specific requirements weren't individually verified - NGWA'S state directory is the fastest way to find the right agency. Expect a written exam (often NGWA's), a separate pump installer license if you do pump work, and per-well permits on top of your license.

Arizona licenses well drillers through the Dept. Of Water Resources, with groundwater protection standards driving the requirements. Arizona has no formal reciprocity for any trade, and well drilling sits outside the Registrar of Contractors entirely.

What applies instead: No reciprocity program was identified. This dataset confirms from the Registrar of Contractors' own page that Arizona has no formal bilateral reciprocity for any ROC trade - and well drilling sits with the Dept. Of Water Resources, a different agency entirely.

Arkansas requires a water well driller license, almost certainly through an environmental, water resources, or public health agency rather than a contractor board. Specific requirements weren't individually verified - NGWA'S state directory is the fastest way to find the right agency.

California regulates well drilling through both the Dept. Of Water Resources (construction standards) and the CSLB C-57 Well Drilling classification. CSLB's reciprocity might apply to C-57, but CSLB'S lists differ by classification - verify rather than assume.

What applies instead: CSLB's standard reciprocity program (Arizona, Louisiana, Mississippi, Nevada, North Carolina) may apply to the c-57 classification subject to it appearing on the Reciprocal Classifications List - but this dataset'S ca roofer and mason records demonstrate CSLB lists genuinely differ by classification, so c-57 coverage must be verified rather than assumed. The DWR side has no reciprocity mechanism.

Note: Confirm whether C-57 appears on CSLB's Reciprocal Classifications List, and confirm DWR's separate requirements.

Maine uses NGWA's vertical closed loop driller exam as an endorsement on its well driller and pump installer licenses - specifically relevant if you'Re doing geothermal loop work. Maine's documented electrical reciprocity is a different board entirely.

What applies instead: No reciprocity program was identified. Maine's precisely-documented electrical reciprocity (journeyman with 6 states, master with NH and VT only) is the Electricians' Examining Board's program and has no bearing here.

Note: Relabeled 2026-07-24: marked official but cited only secondary sources (caught in well-driller completion audit).

Texas licenses water well drillers and pump installers through TDLR - the same agency handling its electricians and HVAC contractors, though the programs are separate. TDLR's documented electrician and HVAC reciprocity does not extend to well drilling.

What applies instead: No well-driller-specific reciprocity was identified. Important: TDLR's extensively documented electrician reciprocity (master with 6 states, journeyman with 11+) and its ACR/HVAC reciprocity (Georgia and South Carolina) are program-specific and do not extend to water well licensing.

Utah requires a water well driller license, almost certainly through an environmental, water resources, or public health agency rather than a contractor board. Specific requirements weren't individually verified - NGWA'S state directory is the fastest way to find the right agency. Expect a written exam (often NGWA's), a separate pump installer license if you do pump work, and per-well permits on top of your license.

What applies instead: No well-driller-specific reciprocity was verified for Utah, and industry sources state plainly that a well driller's license in one state does not automatically grant permission to drill in another. Important: this dataset documents Utah'S contractor-board reciprocity separately - that governs construction trades, not well drilling, which sits with a different agency.

Note: Well driller licensing for Utah needs a dedicated verification pass against the state's own environmental/water agency - start from NGWA's state resources directory.

Vermont requires a water well driller license, almost certainly through an environmental, water resources, or public health agency rather than a contractor board. Specific requirements weren't individually verified - NGWA'S state directory is the fastest way to find the right agency. Expect a written exam (often NGWA's), a separate pump installer license if you do pump work, and per-well permits on top of your license.

Virginia requires a water well driller license, almost certainly through an environmental, water resources, or public health agency rather than a contractor board.

Washington licenses water well professionals through the Dept. Of Ecology, with established continuing education requirements. Washington's narrow L&I trade reciprocity is a different agency and doesn'T apply here.

What applies instead: No well-driller reciprocity was identified. Washington's narrow L&I trade reciprocity (electrical with Oregon only; plumbing with Idaho only) runs through a different agency and does not apply.

West Virginia certifies well drillers and pump installers through the Bureau for Public Health, with annual continuing education required since 2010. One quirk worth knowing: West Virginia does not accept internet-based training for CE credit - the state association opposed it - so those hours must be earned in person.

What applies instead: No reciprocity program was identified. West Virginia's refusal to accept online CE is worth knowing if you maintain licences in several states, since it means WV hours must be earned in person.

Wisconsin licenses drilling rig operators with an NGWA exam option covering rotary mud and rotary air drilling specifically - a method-based structure that's unusual. Wisconsin'S DSPS trade reciprocity is a separate agency and doesn't apply here.

What applies instead: No reciprocity program was identified. Wisconsin's DSPS trade licensing (documented elsewhere, using case-by-case 'Comity' review) is a separate agency and does not apply to well drilling.

Note: Relabeled 2026-07-24: marked official but cited only secondary sources (caught in well-driller completion audit).

Wyoming requires a water well driller license, almost certainly through an environmental, water resources, or public health agency rather than a contractor board. Specific requirements weren't individually verified - NGWA'S state directory is the fastest way to find the right agency.
