APPENDIX B<br />

shorter-term tests, 2- to 4-hours in length, can be used to estimate aquifer characteristics in some cases.<br />

Drawdowns may not be noted in observation wells during short-term tests, so discharge/drawdown data<br />

from the pumping well is critical.<br />

Recovery Phase<br />

When the pump is stopped at the conclusion of the pumping phase, the drawdown and time at which it<br />

was shut down are recorded on forms depicted in Figure B5.7-2. The rate of recovery of the water level<br />

in the wells will then be measured. The same procedure and time pattern for taking water levels is<br />

followed as at the beginning of a test.<br />

The recovery data should be recorded until water levels stabilize, or as long as possible within project<br />

constraints.<br />
