State Well Codes

State Well Codes

The State Well Codes database stores state standards for the construction of private water wells.

Included in the database is state-specific information on various codes related to well construction and siting. To find information on your state or other states, use the searchable database below.

Please note that this database is intended as a guide and occasionally standards change. WSC updates the database periodically, but we encourage you to obtain a full list of state well codes from the websites provided within the States Contact List to the right of this page. 

If you have questions about the database, corrections or updates, please contact Charlene Bean.
