LA CANADA FLINTRIDGE -- Since early this year, NASA has pumped water up
from a contaminated plume beneath the Jet Propulsion Laboratory, removed
about 400 pounds of perchlorate and more than eight pounds of other
potentially hazardous chemicals and re-injected the water below ground.

Now NASA is proposing to expedite that clean-up process by adding an
additional two wells - one for extraction and one for injection - to its
JPL treatment plant. The estimated cost for the additions is $1 million.

Steve Slaten, remedial project manager for the NASA water cleanup
project, said the source area is an eight to 10-acre site near the old
disposal pits. "About two-thirds of all the chemicals that are in the
groundwater still exist in this area in higher concentrations than off
