The site is located in a residential area of Simi Valley, Ventura Co., CA. The spill is located on a approximately 175'x40' section of the 4100 block of Cochran Street (a public street) and on a private alley that serves six homes. Cochran Street is an east-west asphalt road which is two lanes in each direction. There was a 25'x25' section of Cochran Street at the entrance to the alley that contained visible mercury beads.
The alley is approximately 100 yards long and 25' wide. This road is made of degraded asphalt. The six homes are all single family, single story dwellings. Mercury was detected above the action level (3,000 ng/m3 outside and 1,000 ng/m3 inside) on several areas on the alley and residences including one home, a lawn, two residential driveways, two water meter boxes and a planter box.
