 ARLINGTON, Va. (AP) - Every day Larry Slattery goes to work, the Environmental Protection Agency asks him to do the impossible.
Not only does Arlington County's water pollution control chief have to separate sewage and other pollutants from the wastewater gushing into the treatment plant. He also must turn the leftover sludge into a fertilizer and eliminate any risks of spreading illness when it is used.
"Now, it's not possible to totally eliminate everything," he said.
