The Environmental Protection Agency (EPA) is the branck of the US Government that has jurisdiction over Private Water Systems, including Private Wells, throughout the US. Here is their page on Private Ground Water Wells:  http://www.cdc.gov/healthywater/drinking/private/wells/index.html

States also have enacted their own laws. If you are a landlord and own a property that is on a Well, you can find some valuable information at this link from the EPA: http://water.epa.gov/drink/info/well/whereyoulive_state.cfm
