ASTM D4511 - 11 Standard Test Method for Hydraulic Conductivity of Essentially Saturated Peat
Values of hydraulic conductivity determined by this test method may be useful in making rough preliminary estimates of the initial rates of drainage and compression of peat deposits when the only effective stress increase on the deposit is that resulting from a moderate, gradual lowering of the water table. ...

ASTM D7100 - 11 Standard Test Method for Hydraulic Conductivity Compatibility Testing of Soils with Aqueous Solutions
1. Scope 1.1 This test method covers hydraulic conductivity compatibility testing of saturated soils in the laboratory with aqueous solutions that may alter hydraulic conductivity (for example, waste related liquids) using a flexible-wall permeameter. A hydraulic conductivity test is ...
