Cone penetrometer-mounted chemical sensor demonstration
- Environmental Protection Agency, Las Vegas, NV (United States)
Developments in the fields of geophysics, analytical spectroscopy, and foundation engineering are being brought together to create a powerful tool for hazardous waste characterization. Originally developed to provide engineering data, the cone penetrometer (CPT) has become a vehicle for adaptations of geophysical and spectroscopic techniques. In response to input of EPA Regional Office needs, a demonstration of cone penetrometer-mounted chemical sensors was conducted in August and September of 1994. This demonstration evaluated the spectrum of available cone penetrometer sensor technology. Representing the smaller sized units was Geoprobe Systems, while new optical analytical spectroscopy sensors were represented by the Rapid Optical Analytical Tool, or ROST, (a commercial system) developed by Unysis Corporation and the US Army`s Site Characterization and Analysis Penetrometer System (SCAPS). In addition, standard commercially-available, full-sized sensors were evaluated from a contracted rig made available to the demonstration participants by the MMTP. For the purpose of this demonstration, three sites were used including the York Gas and Electric Company Coal Gasification Site in York, Nebraska, which has polyaromatic hydrocarbons (PAH) contamination; a former underground storage tank (UST) site at Ft. Riley, Kansas which has contamination, resulting from fuel leaks; and the Atlantic Coal Gas Company site located in Atlantic, Iowa which has both PAH and fuel contamination. The various technologies and the drill rig independently examined through the three sites during the period 13 August to 2 September, 1994.
