The prolonged drought in Southern California has caused a continuing brush die-off in the heart of the Brentwood nuclear dump. Much of the mapped center of the known dumping areas is easier to see — sloping areas that weren’t tested in the VA Phase I testing of the eastern arroyo. “The average readings for the East Arroyo, West Arroyo, and the Brentwood School lower soccer fields were notably above the Control areas,” the Phase I report read.

These rubble-covered slopes, and what lies beneath them, may have to be excavated to remove nuclear and chemical contaminants because boring for samples would be impossible. Further south along the ridge, under and adjacent the southern field of the Barrington Dog Park, the land is debris-free and marked by a series of 18 mounds down the slope in the eastern arroyo.
