Burleson is providing innovative solutions to treat mine drainage in Napa County for Tuleyome, Inc., a California nonprofit dedicated to protecting the wild and agricultural heritage of the Northern Inner Coast Range. Tuleyome is sponsoring a Good Samaritan mine and water quality cleanup project at the Corona and Twin Peaks Mines in Napa County. The goal is to preserve the century of mining heritage for the public to explore and learn from for generations.
Burleson recently installed two inclined borings and we are conducting tracer studies to evaluate pathways and treatment parameters. The goal of the project is to identify a method to substantially reduce metal loading from mine drainage and improve the effectiveness of existing mine drainage treatment systems to support healthy aquatic ecosystems downstream in Lake Berryessa and Putah Creek, and to mitigate physical and chemical hazards so that the site is safe for potential future public use.
We are also working on consolidation and revegetation of areas where unconsolidated mine waste threatens water quality, as well as improving the existing infiltration trench system to better capture impacted water from the Drain Tunnel, adits, and surface water that has interacted with mine waste.
