Abstract: A chemical control system for controlling volatile hydrocarbons adjacent a dry cleaning machine is providing having a first framework of air distribution pipes positioned adjacent the upper portion of a dry cleaning machine for discharging low pressure air in a predetermined pattern therefrom. A second framework of fluid intake pipes are positioned adjacent to the lower portion of a dry cleaning machine for drawing in air and volatile liquid fumes and filtering the air being drawn thereinto. Sensors are provided for sensing fluids, air pressure, and temperature for controlling the operation of the system. A liquid catch basin is provided under and around the dry cleaning machine for capturing liquids for removal from the liquid catch basin. The system also provides a plurality of fluid discharge pipes placed in the earth below the dry cleaning machine along with pipes for drawing in fluid so that the earth below the dry cleaning machine is cleansed of volatile fluids.

Abstract: A system and method for establishing, maintaining or enhancing microorganisms utilized to remediate contaminated soil or groundwater which includes of a direct push rod or cylinder equipped with a fluid or gas delivery system. The system also includes computer-based monitoring capabilities which can monitor or control the subsurface events. Microorganisms, nutrient solutions, or gases such as air can be introduced into the subsurface environment of predetermined locations. The delivery device is a long rod or cylinder which is pushed into the ground via applied pressure at the surface. The internals of this device contain tubing or other means to deliver fluid through openings in the rod or cylinder to the surrounding environment. The fluid may be driven into the environment by surface pumps or gas pressure. The delivery rod or cylinder may be withdrawn for reutilization or left in place for continuous service.

Abstract: A sampling system and method for obtaining subsurface samples of soil gas and ground water includes a sampling probe which is pushed into the ground with a plurality of thrust rods. The sampling probe has a pointed head telescoped within a sampling housing during insertion. An umbilical tube communicating with the housing is utilized to introduce inert gas into the housing, extending the probe from the housing. Reduction of the gas pressure permits water or gas to flow through a filter and check valve into the housing by piezometric pressure. A computer monitoring system permits control of gas pressure to collect a desired amount of sample and to store data for later analysis.
