DESCRIPTION
The
San Gabriel Valley Superfund sites include multiple areas of
contaminated groundwater in the San Gabriel Basin aquifer, a
critical source of drinking water for water-scarce Southern
California. Approximately 30 square miles of the 170 square
mile San Gabriel Valley are contaminated. The four Superfund
sites include areas of soil and groundwater contamination underlying
portions of the cities of Alhambra, Arcadia, Azusa, Baldwin
Park, Industry, Irwindale, El Monte, La Puente, Monrovia, Rosemead,
South El Monte, and West Covina.

NOTES
 Groundwater
contamination at the site results from the cumulative impact
of decades of spills, improper chemical handling and disposal
practices.
The
cleanup plan requires pumping of approximately 22,000 gallons
per minute of contaminated groundwater and treating it to remove
contaminants at an estimated cost of $150 to $200 million, making
the groundwater cleanup one of the largest and most expensive
in the United States.
The
water treatment systems make use of a variety of processes to
remove the contaminants from the groundwater: ion exchange (to
remove perchlorate and nitrate); ultraviolet light and hydrogen
peroxide (to remove NDMA, 1,4-dioxane, and VOCs); and air stripping
and offgas treatment (to remove VOCs). |
