The SITE Program is formed by five research programs: The Demonstration Program, The Emerging Technology Program, the Measurement and Monitoring Technology Development Program, the Innovative Technology Program, and the Technology Transfer Program. The Emerging Technology (ET) Program has been in existence for five years and has developed several innovative technologies that have shown promise in being applicable to clean-up activities related to hazardous waste problems. Technologies are eligible for the ET Program when sufficient research data exists validating the technologies' basic concepts. The EPA contributes funds to support developers for one or two years. Developers are responsible for conducting research and providing additional financial support in the cooperative research effort. Generally, technologies are categorized into six areas: Thermal, chemical, biological, materials handling, physical, and solidification/stabilization.
