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.
