The Bay is no exception. A survey conducted by the San Francisco Estuary Institute found that seventeen commonly used drugs, including antibiotics, antidepressants, and over-the-counter painkillers, could exceed protective thresholds for marine life. “We want to be vigilant in monitoring these contaminants,” says Diana Lin of SFEI.
