Universal Citation: OR Admin Rules 690-217-0040

Current through Register Vol. 63, No. 9, September 1, 2024

(1) If the well to be tested is within one-quarter mile of a stream, lake or other surface water body, it shall be noted on the pump test report along with the distance between the well and that surface water body. The approximate elevation difference between the land surface at the well and the surface of the water body shall also be noted.

(2) In order for pump test information to be valid, the possible effects from pumping of nearby wells must be evaluated. If there are other wells not exempted under ORS 537.545 which are within 1000 feet of the well to be tested, and which were pumping for all or part of the pump test, the approximate distance to these wells and the approximate pumping rate of each shall be included on the pump test report. If pumping from a nearby well started or stopped during the test or within 24 hours prior to the test, the time the pumping started or stopped shall be included on the pump test report if known or available.
