Abstract

A thixotropic gel suitable for use in subsurface bioremediation is provided along with a process of using the gel. The thixotropic gel provides a non-migrating injectable substrate that can provide below ground barrier properties. In addition, the gel components provide for a favorable environment in which certain contaminants are preferentially sequestered in the gel and subsequently remediated by either indigenous or introduced microorganisms.

Vadose zone water fluxmeter

Patent Faybishenko, Boris A.

A Vadose Zone Water Fluxmeter (WFM) or Direct Measurement WFM provides direct measurement of unsaturated water flow in the vadose zone. The fluxmeter is a cylindrical device that fits in a borehole or can be installed near the surface, or in pits, or in pile structures. The fluxmeter is primarily a combination of tensiometers and a porous element or plate in a water cell that is used for water injection or extraction under field conditions. The same water pressure measured outside and inside of the soil sheltered by the lower cylinder of the fluxmeter indicates that the water flux throughmore »« less

Vadose zone isobaric well

Patent Hubbell, Joel M [Idaho Falls, ID]; Sisson, James B [Idaho Falls, ID]

A deep tensiometer is configured with an outer guide tube having a vented interval along a perforate section at its lower end, which is isolated from atmospheric pressure at or above grade. A transducer having a monitoring port and a reference port is located within a coaxial inner guide tube. The reference port of the transducer is open to the vented interval of the outer guide tube, which has the same gas pressure as in the sediment surrounding the tensiometer. The reference side of the pressure transducer is thus isolated from the effects of atmospheric pressure changes and relative tomore »« less

Tensiometer for shallow or deep measurements including vadose zone and aquifers

Patent Faybishenko, Boris [Berkeley, CA]

A two cell tensiometer is described in which water level in the lower cell is maintained at a relatively constant height, and in equilibrium with the water pressure of materials that surround the tensiometer. An isolated volume of air in the lower cell changes pressure proportionately to the changing water pressure of the materials that surround the tensiometer. The air pressure is measured remotely. The tensiometer can be used in drying as well as wetting cycles above and below the water table.
