Or. Admin. Code § 690-217-0030 - Pump Test Specifications for Flowing Artesian Wells with Pumps
(1) Pump tests for
flowing artesian wells with pumps shall be conducted such that the following
minimum specifications are met.
(2)
The well shall be shut in for at least sixteen hours prior to the test and the
shut-in pressure recorded within the hour prior to the test at least three
times no less than twenty minutes apart.
(3) The pump test shall be conducted in the
same manner as outlined for non-flowing wells in OAR
690-217-0025 except that water levels above ground shall be determined by the use of a
pressure gauge and reported as pounds per square inch (PSI). If at any time
during the test the pressure drops below zero PSI, indicating the water level
in the well has dropped below ground level, the water level shall be measured
by a method listed in OAR
690-217-0045.
