A client has inquired about flexible wall hydraulic conductivity testing (ASTM D5084) of an in-situ sample possibly contaminated with diesel fuels. I have heard about a device, possibly called a bellaphragm (sp?), that would allow monitoring of the outflow from the sample without contaminating...
We are in the process of studying fly ash permeability. My problem is the saturation value. According to my reading of ASTM D5084 the hydraulic conductivity value isn't valid until you have 94% saturation or so. Based on my initial values the sample will be 45% saturated prior to being placed...
