Frontier Fertilizer Superfund Site
Located near the eastern border of Davis, California, Frontier Fertilizer Superfund Site encompasses nearly 14 acres of land. Since 1995, EPA has been operating a groundwater extraction and treatment system. Its remediation efforts also include the use of electrical energy to heat and reduce the most contaminated areas. To offset energy use, a Solar Photovoltaic (PV) System was installed on the roof of the treatment building. The 5.7 kW PV System was designed and installed by CH2MHill and Roseville Solar Electric (RSE) on December 2007 and consists of 30 Evergreen ES-190-RL and190 Watt solar modules formed into ten 3-module panels. Over the course of a full-year, the PV System is expected to produce approximately 8,500 to 9,000 kilowatt-hours of energy, offsetting up to 5% of the site's annual electricity use for Pump & Treat system operations, and saving energy costs of approximately $1,500 per year. EPA plans to add additional panels in FY 2009.
