Medications and personal care products continue to show up in our nation’s water supply – from antidepressants, antibiotics and painkillers to hormones and cosmetics.  There is growing concern about the impact these substances have on plants, animals and humans.  It is time we pay attention to warning signs and start making steps to reduce contamination of our water supply.

 

The Center for Disease Control (CDC) reported in 2008 that 50% of Americans used one or more prescription drugs, and prescription drug use continues to rise.  Since medications enter the water when people excrete them or wash them down the drain, it is important that we be more aware of what we are putting into our bodies and, in turn, into the environment.

 

Sewage systems are not equipped for the removal or medications, so residues of these substances show up in our drinking water.  While human exposure to drugs through the water supply is minimal and below the medical dose, it seems careless to deny the possibilities, especially when you consider the cumulative effect over time and the possible interactions with other chemicals and medications.

 

Aquatic life have exposure to and subsequent bio-accumulation of the residues of medications and personal care products.  Hormone disrupting effects of these substances appear to be leading to changes such as fish with both sex characteristics, male fish carrying immature eggs, and female fish having difficulties being able to reproduce.  More research is needed to determine the full extent of harm on plant, animal and human health.  Until then, we can start making a change by limiting prescription drug use, looking for more eco-friendly alternatives, and properly disposing of unused or expired medications.

 

Reduce Drugs in the Water Supply:

 

• Do not flush prescription medications down the toilet or sink.

• Drop off expired and un-usable prescription medicines at hazardous waste take-back sites or events.  Check with your county’s police department if you have difficulty finding a drop off location.

• Avoid unnecessary medications.

• When medications are necessary, ask your doctor for a prescription with low environmental impact.

• Request your doctor give low prescription amounts and refill options so you can avoid unused excess medications.

• Encourage your doctor’s office to set up take-back for unused and expired drugs.

• Look for lifestyle changes and natural therapies that reduce your need for medications.
