That’s right; even advanced wastewater treatment processes can’t remove medications (known as pharmaceuticals) from wastewater. Traces of medications that pass through the treatment plant can harm aquatic organisms and potentially affect people. To reduce the threat of medications in the environment, dispose of them at a collection facility. In Napa, you can take your medications to Family Drug on Old Sonoma Road or drop them off at the Hazardous Waste Collection Facility. Please note that controlled substances are not accepted at the Hazardous Waste Collection Facility.
