OAR 690-215-0005
Prevention of Groundwater Contamination, Health Hazard, and Waste

(1)

The landowner of the property on which the water supply well is constructed is ultimately responsible for the maintenance and use of the water supply well. All water supply wells should be disinfected following the installation of pumping equipment. Refer to OAR 690-210-0380 (Disinfection of a Well), Appendix 2 for recommendations on well disinfection.

(2)

The landowner shall maintain all water supply wells in a condition where they are not a health threat, a health hazard, a source of contamination or a source of waste of the ground water resource by allowing loss of artesian pressure or commingling of aquifers. A pitless adapter may be attached to the casing to transmit water from the well into the delivery pipeline. The pitless adapter shall be installed in such a manner as to prevent the contamination of the ground water resource. The landowner is responsible to assure that the space between the side of the well borehole and the well casing is sealed as required by OAR 690-215-0025 (Sealing Pitless Adapter and Pitless Units).

(3)

If, in the opinion of the Director, a water supply well is a health threat, a health hazard, a source of contamination, or a source of waste of the ground water resource, the Director may order discontinuance of, or impose conditions upon, the use of the water supply well. In addition, the Director may order that the well be repaired or permanently abandoned in accordance with OAR chapter 690, divisions 215 and 220 of the Standards for Construction and Maintenance of Water Supply Wells in the State of Oregon.
