Telemedicine, the delivery of health care with the patient and health professional at different locations, has been around for over 30 years. Its driving force has been developments in communications technology, and as new communications systems are developed health applications are proposed such as supporting the delivery of primary health care to geographically remote areas or regions underserved through the maldistribution of professional expertise. Despite rapid technological advances, evaluations of such systems have been largely superficial, and more thorough evaluations have failed to show significant advantages for more advanced and expensive technology over older technology such as the telephone. Methods for evaluating the impact of particular technologies on the health care system need to be developed and clearer benefits shown in terms of improved standards of care.
Under the Superfund Innovative Technology Evaluation (SITE) Program, a technology developed by AWD Technologies, Inc. was demonstrated in September 1990. This paper presents the major results of the SITE demonstration of AWD Technologies' AquaDetox/SVE treatment system designed for simultaneous on-site treatment of contaminated groundwater and soil-gas. The groundwater and soil at the demonstration site were contaminated with trichloroethylene (TCE) and tetrachloroethylene (PCE). The AWD technology was evaluated on the basis of the removal efficiencies of TCE and PCE from the contaminated groundwater and soil-gas. The conclusions drawn from these evaluations are: (1) the system achieved removal efficiencies as high as 99.99 percent for groundwater and 99.9 percent for soil-gas; (2) the effluent groundwater was in compliance with the regulatory discharge requirements of 5 micrograms/L each for TCE and PCE for all test runs; (3) the demonstrated 1,000 gpm system has an estimated capital cost of $4.3 million and annual operating and maintenance cost of approximately $820,000.
