There are pharmaceuticals in my drinking water?
Unfortunately, there is a high chance that there are traces of pharmaceutical drugs in tap and bottled water. I was very surprised myself to learn about this sad fact. The tap water in the United States in arguably the cleanest and safest drinking water in the world that is free of microbes and other harmful chemicals. (1) According to the Associated Press investigation, there are varying drugs such as antibiotics, anti-convulsants, mood stabilizers, and sex hormones found in the drinking water supplies of at least 41 million Americans. (2) But how exactly does this happen? What are the environmental and health implications of having drugs in our drinking water?
How Do They Enter Our Drinking Water System?
Over last few years, the numbers of U.S prescriptions have rose 12%, tallying up to 3.7 billion prescriptions. Adding nonprescription drug purchases to this list adds another 3.3 billion.(3) With a grand total of 7 billion prescription drugs entering a population of 320 million people, there is no wonder why our drinking water is contaminated. When people take these medications, not all of the medicine is absorbed by the body. Therefore, unmetabolized or unused drugs are being flushed down the toilet. The waste water is then treated and released in reservoirs, lakes, and rivers. Next, some of that water is cleaned at treatment plants and then piped to consumers. (4) The problem is that most of these treatment plants do not remove all of the drug residue.
But wait, human waste and voluntary disposal are not the only causes for contamination in our water system. The drugs that veterinarians use to treat animals with arthritis, cancer, heart disease, diabetes, allergies, dementia, and even obesity are sometimes the same drugs that are used to treat humans. (5) Similar to humans, the drugs are still prevalent in the waste by products. In the same way that thorough human waste drugs enters our water system, animal waste is washed into streams, rivers, and groundwater systems. This not so pure water eventually ends up in our bodies.
The Effects On Human Health & The Environment
Although these drugs are found at parts per billion and per trillion, scientists are still concerned about the lifetime effects of these drugs floating around in our drinking water. There is research evidence to support that small amounts of medicine can have devastating effects on human embryonic kidney cells, human blood cells, and human breast cancer cells. It can cause kidney cells to grow too slowly, cancer cells to proliferate exceedingly, and the blood cells showed signs of biological activity associated with inflammation. (6) Additionally, there is evidence from the global and national community of the damaging impacts that pharmaceutical ridden waterways can have on wildlife. Male fish have been found to essentially turn into female fish by creating egg yolk proteins which is usually found in females! (7) This is a clear red flag that having drugs in our water (although in a small amounts) is definitely not beneficial to human or Environmental health.
So now the big question is what can we do about our drinking water? Apparently it does not matter whether you drink tap or bottled water; we are all still at risk. It is time that we pressure our government and the Environmental Protection Agency (EPA). As human beings we are entitled to clean drinking water and safe food. It is about time we the people of this nation truly had the power to change the ball game for all our sakes (and the environment’s!). Over the past few weeks in this blog series, we have been posting many articles about how one can save energy. However, this is time when we need to use it. We need to use the energy that it requires to protest, write to congress, and voice our opinions. Don’t you want to know what’s floating around in your drinking water?
