Some Helpful Links on Pharmaceuticals in Drinking Water

The Associated Press investigation on drinking water contamination by pharmaceuticals is a recent installment to the ongoing research about this topic. The U.S. government as well as other scientists have been studying this issue for some time. Here are some interesting links about the topic:

EPA information on Pharmaceuticals and Personal Care Products in the Environment (PPCPs): Frequently Asked Questions about PPCPs in the environment and basic introduction.

USGS What's In Our Wastewater and Where Does It Go? an array of studies and articles on contaminants in wastewater. "The U.S. Geological Survey (USGS) has implemented a national reconnaissance to provide baseline information on the environmental occurrence of "emerging contaminants" such as human and veterinary pharmaceuticals (e.g., fluoxetine and lincomycin), industrial and household wastewater products (e.g., p-nonyphenol and triclosan), and reproductive and steroidal hormones (e.g., equilenin and progesterone) in water resources."

An Associated Press investigation found that pharmaceutical drugs are widespread in drinking water suppliers. No one really knows what are the long-term health effects. This is yet another reason to install water filtration in your home. Reverse osmosis is one type of home system that is supposed to remove these drugs.

The Controversy Over Bottled Water: One Solution--Home and Office Water Purification

Recently after San Francisco Mayor Gavin Newsom (2007) banned the purchase of bottled water by City funds, there has been greater discussion about the benefits and drawbacks of bottled water. Some argue that the transport and processing of bottled water as well as the disposal of bottles negatively impacts the environment. They also argue that tap water is as healthy as bottled water.

While municipalities across the country do remove a majority of water contaminants, it is also true that there are residual contaminants in the water. The disinfection process also adds chloramines and other byproducts. The United States Environmental Protection Agency (EPA) regulates allowable levels of contaminants in drinking water. A list of contaminants and their possible adverse health effects is available on the EPA website:

The EPA categorizes possible water contaminants into: microorganisms, disinfectants, disinfection byproducts, inorganic chemicals, organic chemicals, and radionuclides. There can also be turbidity from soil runoff and other nonregulated contaminants. Not mentioned on this list are possible contaminants, such as copper or lead, after municipal processing from local water pipes.

In reviewing the water quality report for my local city, for instance, I found small and permissible amounts of lead, copper, barium, nitrate, atrazine (herbicide), simazine (herbicide), and chloramines, among others. Even if the low levels present are acceptable by EPA standards, it is a personal choice as to whether one would prefer to ingest even lower levels of contaminants and also have better tasting water.

One solution is to add a whole house/office or individual faucet water purification system to remove the residual contaminants. Seagull, for example, offers water purification systems with a “structured matrix technology” that remove trace amounts of chemicals and any microbiological contaminants found in tap water and creates water quality that is as good as or better than bottled water. In fact, the structured matrix is also “certified to meet the EPA standard for microbiological ‘purification’.”

There is also the added benefit of having purified water for pennies per glass instead of the higher cost for bottled water.
