aquifer designated by the United States Environmental Protection Agency
pursuant to Section 1424(e) of the Safe Drinking Water Act (42 U.S.C.
300h-3(e)), unless there is a stratum between the bottom of the waste disposal

1) The stratum has a minimum thickness of 15.2 meters (50 feet);
2) The maximum hydraulic conductivity in both the horizontal and
vertical directions is no greater than 1x10
-7

3) There is no indication of continuous sand or silt seams,
faults, fractures or cracks within the stratum that may provide paths for
migration; and
4) Age dating of extracted water samples from both the aquifer

meters (50 feet) in 100 years.
