South El Monte : Tests Find Contamination
Tests have uncovered ground water contamination under Lee Pharmaceuticals on Santa Anita Avenue.
Soil and water studies were begun after the company applied for a county permit to stop using an underground chemical storage tank.
The Regional Water Quality Control Board is studying ways to clean up the acetone and methylene chloride contamination before it reaches drinking water stored in wells.
A spokesman for Lee Pharmaceuticals, which manufactures cosmetics and dental filling materials, said the storage tank was empty and that the contaminants were found only in ground water and not in soil samples.
