Where is the site?
The Guadalupe Restoration Project is located at the coast, west of the city of Guadalupe, along the southern edge of San Luis Obispo County. The Santa Maria River flows through the southern edge of the site.

Where is the oil?
Over the years, diluent was inadvertently discharged at the former Guadalupe Oil Field. There are approximately 90 separate-phase (or "free product") and dissolved-phase diluent plumes.

Why don't you just dig it all up?
The Guadalupe oil field is a rich dune habitat, home to a variety of threatened and endangered species. A key challenge is to eliminate potential damage to the environment while protecting sensitive habitats and species.
