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 your state environmental agency or contact the wellcare® Hotline for assistance. 

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

Please click on the State Name in the list below for well code information. If you would like to alphabetize the table, click on the column name in blue.
