Frequent Questions

Does the EPA track the number of wells by state, specifically for Class V Stormwater  Drainage Wells?

The EPA does track Class V well inventories by state and posts that information on the web at https://www.epa.gov/uic

Unfortunately, it does not track Class V wells by subcategory.  States with primary enforcement authority for the UIC program may post that information on their individual state UIC websites.  EPA manages the Class V program in several states including PA, VA, NY, CA, MN, and SD. Individual EPA regional UIC programs track that information for those states.
