OAKLAND, Calif. -- Sewage water dumped into San Francisco
Bay contains potentially dangerous chemicals found in household
products such as deodorant and plastic bottles, according to a
recently released study.
Researchers detected the synthetic chemicals in two dozen water
samples from sewage pipes connected to homes, businesses and
manufacturing plants, according to the report released by
Environmental Working Group's office in Oakland.
The nonprofit group made the study with the East Bay Municipal
Utility District, one of dozens of agencies that discharge treated
sewage, storm water or other wastewater into the bay.
Inspectors found three types of chemicals -- phthalates, bisphenol
A and triclosan -- suspected of interfering with hormone systems of
humans and wildlife.
Researchers believe chemical ingredients are leaching out of
household products such as toothpaste, soap and plastics, passing
through the municipal sewage plants virtually untreated.
Modern sewage systems are designed treat biodegradable food, human
waste and metals, but not to capture the thousands of tons of
synthetic chemicals used to manufacture consumer products, EBMUD
