Drugs and Personal Care Products Polluting Water (cont.)
Should we be worried about ecological and/or human health?
Studies have shown that pharmaceuticals are present in some of our nation's waterbodies. Further research suggests that there may be some ecological harm when certain drugs are present. To date, no evidence has been found of human health effects from PPCPs in the environment.
Where are PPCPs found in the environment?
PPCPs are found where people or animals are treated with drugs and people use personal care products. PPCPs are found in any water body influenced by raw or treated sewage, including rivers, streams, ground water, coastal marine environments, and many drinking water sources. PPCPs have been identified in most places sampled.
The U.S. Geological Survey (USGS) implemented a national reconnaissance to provide baseline information on the environmental occurrence of PPCPs in water resources. You can find more information about this project from the USGS's What's in Our Wastewaters and Where Does it Go? site.
PPCPs in the environment are frequently found in aquatic environments because PPCPs dissolve easily and don't evaporate at normal temperature and pressures. Practices such as the use of sewage sludge ("biosolids") and reclaimed water for irrigation brings PPCPs into contact with the soil.
How is the disposal of unused pharmaceuticals regulated by the US EPA?
The Resource Conservation and Recovery Act (RCRA) is a federal law controlling the management and disposal of solid and hazardous wastes produced by a wide variety of industries and sources. The RCRA program regulates the management and disposal of hazardous pharmaceutical wastes produced by pharmaceutical manufacturers and the health care industry. Under RCRA, a waste is a hazardous waste if it is specifically listed by the EPA or if it exhibits one or more of the following four characteristics: ignitability, corrosivity, reactivity and toxicity.
How do I properly dispose of unwanted pharmaceuticals?
In February 2007, the White House Office of National Drug Control Policy issued the first consumer guidance for the Proper Disposal of Prescription Drugs. Proper disposal of drugs is a straightforward way for individuals to prevent pollution.
