"  The Dig An excavator sitting on a barge reaches with a dredging claw to scoop sediment from the river bottom. The contaminated layer averages 21 inches thick; in certain spots the deposits are piled 10 feet high. Scoop by scoop, workers load the barge with the toxic sludge and head to shore. The Delivery A second excavator moves the dirt from the barge to a facility where a dozen 32-ton filter presses, similar to those used in winemaking, squeeze water from the slurry. The resulting filter cake is sealed inside one of 450 plastic-lined railroad cars bound for Texas.  The Dump In Andrews, Texas, more than 2000 miles away from Albany, the filter cake is carefully unwrapped and laid to rest in a very sophisticated hole in the ground. The landfill uses layers of mesh, clay and plastics to isolate the cakes from the surrounding soil, the water below and the air above.  Tom Jones, representative for the landfill engineering firm Waste Control Specialists, expressed confidence that the people of Andrews, Texas, would be comfortable with train loads of toxic sludge coming to town. &amp;quot;This is oil field country,&amp;quot; Jones said. &amp;quot;Everyone knows someone that&amp;#039;s lost a finger or broken a back out there. You might say we relate to risk a little differently than people not from around here.&amp;quot;  "^^<http://www.w3.org/2001/XMLSchema#string>
