The cleanup of a chemical spill from a ruptured storage tank at an Escondido, Calif., water-treatment facility has cost the city more than $1 million so far, said city Utilities Director Chris McKinney. The City Council has approved a contract for as much as $2 million to remediate the spill of a solution including sodium hydroxide, also known as lye. The cleanup involves the removal and replacement of 1,700 tons of contaminated soil.
