Tests of yield

All water supply wells shall be tested for yield and capacity, as provided by Section 19-13-B51 K (b) of the Public Health Code, and all static and pumping water levels and well discharge shall be measured and recorded, with the pumping rate held constant. The test shall be made by one of the following methods: the pump method, the bailer-recovery method, the air rotary drill method, or the air lift method. For wells serving a single family the well may be tested for yield by removing as much water as is practicable from the well and measuring the rate of recovery.
