Phased Reclamation at the Jordan River, Midvale Utah
Jordan River riparian restoration was conducted as part of the final remedy for the Midvale Slag Superfund Site. Phase I of the riparian restoration called for the replacement of a damaged and dangerous sheet pile dam that was built to maintain river bank stability for the portion of the Jordan River running adjacent to the Site. The dam reduces bank erosion and prevents the release of buried contaminants into the river and other adjacent properties. A river energy/flow survey of was conducted to develop a two-dimensional model to evaluate the hydraulic characteristics of the river at different stream flows. The model allowed EPA to determine where the highest velocities occurred and indicated areas susceptible to erosion and/or migration of stream flows out of the current channel. The model also provided water-surface elevations throughout the reach for various streamflow’s and aided in planning where increased cross sectional areas were needed and where to install velocity abatement structures. Information obtained from the model was used to curb the effects of erosion and strengthen the stability of the cap for the Midvale Site. In addition, two doctorate summer interns were hired to conduct detailed soil and weed studies for information used for planning future phased work.

Phase 2 of the riparian effort included replacing debris/weeded areas with native plants, and some armoring. This Phase included outreach to the community on a variety of projects including education, building bridge abutments for future pedestrian bridges to be built by the city and developers, weed mitigation, pedestrian trail expansion, and improved river access for recreational use. Additionally, Phase 2 included opening up the river up-stream to slow the flow to reduce potential damage downstream. Phases 4 and 5 were a continuance of earlier phases making adjustments.

The reclamation portion of the Superfund work was conducted using Veteran Owned Small Business and Minority Owned Small Business as well as task specific grants to Salt Lake County and the USGS. In short, the work conducted was cost effective using mostly local resources.
