Spanish Springs Valley Nitrate Remediation Pilot Project Phase III

Department of Water Resources, Spanish Springs Valley, Washoe County, Nevada

EPA is considering authorizing the expenditure of funds awarded to Washoe County, NV. Washoe County received appropriations from congress to fund water infrastructure projects. Funding will be used to reduce nitrate contamination in Spanish Springs Valley groundwater by extracting groundwater with high concentrations of nitrate and injecting potable water with low levels of nitrate into the groundwater. Previous congressional appropriations were awarded to Washoe County to investigate and characterize the extent of nitrate contamination in the aquifer. This project, Phase III, will fund actions to clean up nitrate contamination. This project uses two existing wells that have been taken out of operation. The remediation project will re-activate the existing wells to extend the life of this infrastructure. Monitoring of nitrate concentrations in groundwater at the extraction and injection sites is included in the project to assess changes in concentrations of nitrate over time. The project and budget period is three years.

This notice announces the availability of the EA and draft Finding of No Significant Impact (FONSI) for public review and comment.
