Benzene Vapors in a Residential Neighborhood in California
From the Daily Breeze.com a story of benzene contamination in a residential neighborhood.
Soil contaminated with toxic substances covers a 16-acre swath centered in the 2100 block of Del Amo Boulevard, with the highest concentrations found in a 4.5-acre tract, authorities said.
That smaller area is where an investigation has detected levels of carcinogenic benzene vapors at levels of up to 20,000 parts per billion, say officials from the ExxonMobil Torrance Refinery.
The state mandates remedial action - in this case testing and monitoring - when benzene levels in residential areas exceed 10 parts per billion.
