    摘要: An apparatus for extracting groundwater from a well extending below the static groundwater table includes an extraction pipe having a distal end located a predetermined distance below the static groundwater table, and a proximal end adapted for communication with a source of subatmospheric pressure. The extraction pipe includes a "bubbling hole" a short distance above a static water column established in the well to introduce air bubbles into the extraction pipe to augment the vacuum in lifting the water through the extraction pipe. A method of extracting groundwater employing this apparatus includes the steps of (1) measuring the height of the static water column in the well; (2) providing an extraction pipe having a proximal end, a distal end, and a hole located axially along the length of the extraction pipe at a specified distance from the distal end thereof; (3) extending the extraction pipe into the well so that the distal end of the extraction pipe is located at a first predetermined distance below the static groundwater table, and the hole is located a second predetermined distance above the static water column in the well; and (4) applying a subatmospheric pressure to the proximal end of the extraction pipe, the magnitude of the subatmospheric pressure being sufficient to lift the groundwater through the proximal end of the extraction pipe with the assistance of air bubbles introduced into the extraction pipe from the well through the hole.

    摘要: This invention has three parts: Part 1 Two-phase extraction of contaminated water and vapor from extraction wells using drop tubes with vertical slots or orifices; Part 2, Separation of extracted water and vapor/air at the wellhead or in a common manifold installed in ground, Part 3 injection of the extracted water using injection well with a drop tube similar to drop tube in the extraction well without the orifices or slots that extend above and below the water table. This invention strips volatile organic compounds from water, creates a recirculation cell in subsurface, increases biodegradation of organic compounds within the recirculation zone. This inventions also facilitate performing enhanced in-situ bioremediation or chemical oxidation by adding oxidation chemicals or bioremediation substance into the injection stream.
