    Review of this standard to the ASTM Style Manual found that this standard should be a Practice instead of a Test Method, as it only takes data from another test method and mathematically manipulates it to evaluate the aquifer. The standard has been revised into a practice to address this Enter reasons for proposed ballot action. Included are updates on caveats and other editorial corrections.
