Chemicals in Well and City Water - An Invisible Danger to Health

It’s impossible for our city’s water treatment plants to completely remove animal and human pharmaceuticals from our drinking water supply. The water companies also struggle to deal with weed killers, pesticides and other industrial chemicals, commonly known as dioxins.These enter the water supply via runoff (when it rains, they run off the land into rivers and lakes). Or they are legally dumped into our natural freshwater sources.(1)

These chemicals contain compounds that act like female hormones and are dangerous to our health.

The water treatment companies “remove” them from sewage by allowing them to fall to the bottom of sedimentation tanks where they are absorbed into a layer of sludge at the bottom. This sludge is then sold to farmers for use as a crop fertilizer. So essentially,the same toxic residues are recycled and eventually seep back into the ground,infiltratingunderground aquifers and well water supplies.

On top of this, the water companies use chlorine-based treatments to kill bacteria.This triggers a chemical reaction that produces compounds which are over 300 times more toxic than the original chemicals (pesticides and weedkillers for example) themselves! These disinfection byproducts end up in tap water and have been linked to cancer and birth-related problems.(2)

Another potent source of chemicals in both well water and city water is the liquid that leaches out from solid waste landfill sites. This toxic gloop contains everything from techno trash to paint cans. It’s so concentrated that just a small amount will pollute large amounts of groundwater, leaving it unsuitable for domestic use.

In addition, a frighteningly out of control amount of packaging material and garbage is floating around in rivers and seas. According to a recent study, every one of us is ingesting up to 2,000 tiny pieces of plastic every week, with drinking water being the largest source.(3)Again, our waste water treatment plants are not designed to remove them.

BPA, or Bisphenol A, for example, was developed for use as a synthetic estrogen. Scientists later realized it could be used to make a hard, clear form of plastic.It is also found in everything from sunscreens and detergents to paints and pesticides. When these products are consumed or otherwise discarded by humans, the BPA they contain mostly ends up in sewage works.BPA is known as a “forever chemical” because it persists for decades which means its concentrations keep intensifying. This is why it is commonly found in drinking water from both municipal and well supplies at increasing levels. (4)

Triclosan, which is found in antibacterial/disinfectant products such as hand sanitizers and wipes has similar effects to BPA. Then there are phthalates, the plasticizing substance found in a massive variety of everyday products like food (emulsifiers and stabilizers), detergents, makeup and perfumes.

This massive influx of man-made synthetic estrogens into our water supplies is disrupting the hormonal activity of humans. Thousand of studies have linked these substances to infertility and disease.(4)

So, although your water may look and taste “normal” and standard tests may suggest that it is “safe” to drink, it is most likely to contain a cocktail of chemicals that can only be removed with a sophisticated filtration system that is designed to eliminate these substances prior to point of use.

Central Florida Water Treatment has advanced, state of the art refining systems that can vastly improve the quality of both well and city water by helping to remove these chemicals – providing you and your family with purer, healthier drinking water on tap.
