Embodiment Construction

[0030]Referring now to the drawings, and firstly to FIGS. 1, 2 and 3, the groundwater sampling device is shown in FIG. 1 generally by numeral 10 and includes a water sampling device 12 in the form of a submersible groundwater pump, an electrical conduit 14 which interconnects a voltage controller / booster device 16 to the device 12 and further includes a collector (not shown) into which the groundwater is pumped out of a pre-established well of small internal ID (not greater than 1.5 inches) through a water conduit 22 for collection and / or analysis.

[0031]The device 12 is described in more detail hereinbelow and is positionable within the well formed into the ground below grade level. The depth to which the device 12 descends is controlled primarily by the feeding of the electrical conduit 14. An optional system voltage / current controller / booster 16 as will be further discussed below includes a connection to the electrical conduit 14. Electrical contacts 34, which are attachable to th...

Abstract

A groundwater sampling and pumping device and system for withdrawing groundwater from a well of small size, not exceeding 1.5 inches I.D. The device includes a hollow outer housing having water inlet ports formed through a bottom thereof and a hollow inner housing sized to be positioned integrally within the outer housing and defining a water flow passage therebetween. An electric motor in the inner housing is connected to a water impeller operably positioned to draw groundwater into the water passage. The water passing upwardly through the water flow passage provides cooling for the motor. Preferably the housing is formed of a polymer material, and/or a metal, such as stainless steel.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a non-provisional claiming domestic benefit of provisional application No. 60 / 992,248 filed Dec. 4, 2007 and provisional application No. 61 / 051,527 filed May 8, 2008, the entire disclosures of which are herein incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]This invention relates generally to systems and methods for gathering liquid samples using a submersible pump placed into a pre-established well for analysis and / or groundwater removal and groundwater remediation and circulation of fluids, and more particularly to a device and system for these purposes with includes a centrifugal pump which is sized to fit into a well of 1.5 inches, or less, such as a well having an inner diameter of one inch, or less, and capable of sending a water sample upwards of 30 feet for collection and / or analysis.[0004]2. Description of Related Art[0005]The taking of groundwater samples from a pre-e...
