US Patent:

59229500, Jul 13, 1999

Filed:

Oct 22, 1997

Appl. No.:

8/955548

Inventors:

Bradley E. Pemberton - Aiken SC
Christopher P. May - Columbia MD
Joseph Rossabi - Aiken SC
Brian D. Riha - Augusta GA
Ralph L. Nichols - North Augusta SC

Assignee:

Westinghouse Savannah River Company - Aiken SC

International Classification:

E21B 4908
E21B 4700
G01N 110

US Classification:

7315228

Abstract:

A sampling port is provided which has threaded ends for incorporating the port into a length of subsurface pipe. The port defines an internal receptacle which is in communication with subsurface fluids through a series of fine filtering slits. The receptacle is in further communication through a bore with a fitting carrying a length of tubing there which samples are transported to the surface. Each port further defines an additional bore through which tubing, cables, or similar components of adjacent ports may pass.

Appl. No.:

9/051076

Inventors:

Mark A. Phifer - North Augusta SC
Ralph L. Nichols - North Augusta SC

Assignee:

Westinghouse Savannah River Company - Aiken SC

International Classification:

B01D 100
B01D 1500

US Classification:

210747

Abstract:

An apparatus is disclosed utilizing permeable treatment media for treatment of contaminated water, along with a method for enhanced passive flow of contaminated water through the treatment media. The apparatus includes a treatment cell including a permeable structure that encloses the treatment media, the treatment cell may be located inside a water collection well, exterior to a water collection well, or placed in situ within the pathway of contaminated groundwater. The passive flow of contaminated water through the treatment media is maintained by a hydraulic connection between a collecting point of greater water pressure head, and a discharge point of lower water pressure head. The apparatus and process for passive flow and groundwater treatment utilizes a permeable treatment media made up of granular metal, bimetallics, granular cast iron, activated carbon, cation exchange resins, and/or additional treatment materials. An enclosing container may have an outer permeable wall for passive flow of water into the container and through the enclosed treatment media to an effluent point. Flow of contaminated water is attained without active pumping of water through the treatment media.
