This process is experimental and the keywords may be updated as the learning algorithm improves.Īnderson, M., Jones, M., Lewis, S., and Baxter, K. These keywords were added by machine and not by the authors. Successful aquifer hydraulic testing requires attention to detail and careful consideration of the underlying assumptions of the various methods used to interpret the data. APTs can provide important information on well yields, well efficiency, and the stability of water quality. Aquifer hydraulic testing may also be performed by injecting water into a well. Aquifer performance tests (APTs), also referred to as aquifer pumping tests, involve the pumping of an aquifer at a known rate and the measurement of the corresponding changes in water levels in the pumped and observation wells. Aquifer pumping tests are an integral component of aquifer characterization because they provide quantitative data on large-scale aquifer hydraulic properties such as aquifer transmissivity, storativity, and the vertical hydraulic conductivity (leakance) of confining strata.
