SWI teamed with Natural Channel Design, Inc. to design one mile of stable stream channel and approximately seven acres of natural wetlands on a 120+ acre U.S. Department of Energy (DOE) Superfund project that was the former site of a uranium processing mill in Monticello, Utah. The stable channel design included determination of the stream's dimension, pattern and profile; channel alluvium gradation analysis and specification; and design of off-channel wetlands fed through infiltration galleries and backwater ponding. Several significant remediation design requirements and performance targets were established by the Utah Department of Environmental Quality (UDEQ), the U.S. Department of Energy, and the U.S. Environmental Protection Agency (EPA). All engineering tasks were completed on schedule and within budget. Grow-in of the wetland, riparian and upland vegetation is expected to take one year.

This project set a milestone in DOE site cleanup administration, as the DOE turned the lands over to the City of Monticello upon removal of all radioactive soil, and allowed the City to act as the principal-in-charge of final stream and wetland restoration activities. DelHur Industries, Inc. utilized creative construction techniques to complete this 2.3 million dollar project on time and within budget.

This project was completed in 2001.
