The Los Angeles City Council on Tuesday requested another $4.8 million from the federal Superfund toxic waste cleanup program to remove chemicals from San Fernando Valley ground-water supplies, bringing its funding request to $12 million.
An application for the additional funds from the U.S. Environmental Protection Agency was approved unanimously and without discussion by council members and sent to Mayor Tom Bradley for his expected approval. A spokesman for the city Department of Water and Power said the EPA is expected to act on the city's request within two months.
The funds will be used to build an aeration tower in North Hollywood, which will remove contaminants from the water, and to conduct a study to determine the extent and sources of the pollution in ground-water supplies.
Joe Hegenbart, the DWP's assistant engineer of water design, said the department has received all the permits needed to begin construction of the tower once it receives EPA funding. The cost of the project has increased because more work may be required than originally expected for studying the pollution problem, he said.
