EPA begins testing air in homes near South Bay Superfund sites
from Los Angeles Times
Nearly 15 years after crews dug up and replaced contaminated soil from Cynthia Medina's frontyard, federal officials have placed dart-sized air quality samplers in her South Bay home. The tests will reveal whether dangerous vapors are seeping inside from polluted groundwater below her house. The U.S. Environmental Protection Agency last month began testing the air inside dozens of homes near two of the nation's worst chemical dumping sites for trichloroethylene, benzene and chlorobenzene. They were prompted by worries that, through a process known as vapor intrusion, the pollutants could be evaporating through the soil and into homes and putting residents at risk.
