Well Destruction
An open, abandoned well constitutes a physical hazard and forms a vertical pathway for movement of bacteriological and chemical contaminates into the groundwater supply. Any toxic or adulterating substances entering the well may, in time, migrate to aquifers furnishing water to nearby wells.
In addition, a deteriorated and corroded well casing can cause degradation of the groundwater by intermixing aquifers. To apply for a well destruction permit, please complete the required form: Encroachment Permit Application Form and submit it to the Public Works Department via email at publicworks@pattersonca.gov
The City of Patterson currently has an agreement with Stanislaus County Effective February 2019. All permitting for Septic Tanks must go through the Environmental Resource Division at the County office.
