Refined? is part of a triptych of artworks about land use near San Francisco Bay. The triptych is inspired by a talk by the poet Gary Snyder where he asked the audience bioregional questions such as 'do you know where your water comes from?' 'do you know where it goes when you're done with it?' 'do you know where your garbage goes?' and so on. Refined? is an aerial view of the Chevron Refinery in Richmond. The refinery extends over 2500 acres and processes 225,000 barrels of crude oil daily. Most of that oil comes from the Alaskan north slope. The location of this refinery, on the edge of San Francisco Bay, was chosen for the convenience and efficiency of delivering oil by tanker ship. The water quality of the bay has paid a high price for this convenience. Dioxin and PCB discharges from the refinery have polluted the waters around the refinery – eating any oysters or fish caught in this area is a serious health hazard. The refinery is the largest industrial polluter in the region and has been fined in the past for discharging untreated toxic wastewater into the bay. Having industrial processing like this right next to the bay highlights the vulnerability of the bay and the vigilance we must maintain in protecting it.
