Abstract

A portable ground water sampling apparatus has a submersible pump or other water sampling apparatus attached through a hose to a hydraulically driven spool mounted on a boom attached to the bed of a truck or trailer. The hydraulically operated boom enables the operator to place the pump over the well and lower the pump into the well from the spool. A second spool also mounted on the boom operates a cable attached to a discrete liquid sampler or appliance of operator'"'"'s choice for lowering into the well to take water samples or collect data. A decontamination apparatus is also attached to the boom and washes the hose and cable to remove contaminants therefrom. The contaminated wash fluid is removed to a holding tank for later disposal at a safe site. Hydraulically driven level-wind mechanisms are attached to each spool. One or more computers are used on site to track the pumping and purging, as well as monitor sensors measuring fluid characteristics, such as, temperature of the water, conductivity and flow.

Claims

1. A portable ground water testing apparatus comprising in combination:

a boom member rotatingly attached to a portable bed, said boom member having slide members to accommodate cables and hoses;

at least two reel members attached to said boom member for storing cables and hoses for use on said boom member;

at least one decontamination apparatus having a chamber with a forward and a rearward aperture for a hose and a cable to pass through said chamber, said chamber having a spray wash device for spraying the hoses and cables with wash fluid to remove contaminants, and means for removing the contaminated wash fluid from the chamber;

a holding tank for accepting and storing the contaminated wash fluid from the decontamination apparatus;

at least one device for maintaining a uniform winding of cables and hoses on said reel members;

a portable computer for monitoring a series of sensors taking data on the characteristics of water samples being taken by the ground water testing apparatus and for controlling the flow of water samples to a series of holding tanks;

a plurality of sensors for monitoring the characteristics of ground water samples being taken, said sensors being connected to said portable computer for purposes of control and transmitting data;

a plurality of holding tanks sequentially connected to a ground water line from a submersible pump, the input into said tanks being controlled by a respective plurality of valves being controlled by said portable computer;

a control apparatus connected to said portable computer for controlling the operation of a submersible pump for taking ground water samples.

2. An apparatus as set forth in claim 1, including a printer connected to said computer.

3. An apparatus as set forth in claim 1, including sensors for monitoring water temperature, water pH, conductivity, and rate of flow.

4. An apparatus as set forth in claim 1, wherein said sensors are connected to a manifold attached to the ground water line.

5. An apparatus as set forth in claim 1, having means for transmitting data from said computer to another computer.
