US EPA Approves Price Canyon Aquifer Exemption

The US Environmental Protection Agency has approved an aquifer exemption for the Arroyo Grande oil field near San Luis Obispo. This enables Sentinel Peak Resources, the current owner of the oil field also known as Price Canyon, to move forward with a planned expansion of wells for both enhanced oil recovery and dispoal of wastewater, or “produced water.” In a decision dated April 30, the director of EPA’s water division said the underground formation beneath the oil field does not, and will not in the future, serve as a source of drinking water due to the presence of “commercially producible quantities of hydrocarbons.”

Wasting Wastewater: New Report Identifies Water Recycling Opportunities

In California, it is a persistent challenge making water supply and water demand match up. A report being released Wednesday outlines how much water California’s coastal wastewater treatment plants dump into the ocean, and how much of that could be saved through better water management. James Hawkins is a water policy researcher at the Santa Barbara-based Heal the Ocean. The nonprofit is focused on reducing ocean pollution, and undertook a multi-year study of the state’s recycling potential. They did so by compiling an inventory of wastewater discharges into coastal waters, wastewater coming from urban cities along the coast.
