Frequently Asked Questions

What Do I Do With An Old Unused Well On My Property?

Cover the well with a watertight, bolted-on cover. This will prevent contamination from polluting the ground water and prevent any child from becoming injured from it. A well designated as an abandoned well must be destroyed. 

Can I Destroy My Own Well?

The owner of the well can obtain the permit to destroy or drill a well, but a C-57 State licensed well contractor must do the abandonment.

Who Works On Wells?

Licensed well contractors with a valid C-57 are qualified to drill and destroy wells. See our Contractors List for a listing of contractors known to do business in Yolo County.

Can You Test My Drinking Water Well For Agricultural Chemicals?

Yolo County Environmental Health Division (YCEH) cannot test for agricultural chemicals or other organic chemicals. Consult an Environmental Health Specialist for chemicals that may be found in the ground water of your area, then contact a state certified drinking water lab for analysis. For a fee, YCEH can test for coliform bacteria and nitrates. Contact Us for more information on water testing, or to arrange to have us test your water for Coliform bacteria or nitrates. For information about the Coliform test: what it is, how to get it, what it means, and what to do if the test is positive, see our Coliform Testing Questions and Answers Page.

How Long is My Well Permit Good For?

Yolo County Code section 6-8.804 (b) states that well permits expire and become null and void if the work is not commenced within 120 days (4 months) after the date of permit issuance or if the work is suspended or abandoned for a period of 120 days any time after the work is commenced.

Due to the construction time being unpredictable and the County Code being too restrictive, Yolo County Environmental Health has developed the following policy regarding well permit expiration:

A permit shall be considered valid for two (2) years.

Renewal of a permit may be granted for a period of two additional years provided no changes have been made or will be made to the original plans and specification for such work. The fee to renew the permit shall be 1/2 of the current permit fee. The renewal request shall be made prior to the expiration of the permit and the permit can be renewed one time.
