When water is a part of everyday life, it’s easy to forget how essential access to clean water is. Unfortunately, the United States doesn’t provide more filtration for our water, so even with municipal water treatment, your water may still have contaminants.

The Environmental Working Group (EWG) found that over 100 million Americans have arsenic, nitrates, and chromium-6 in their drinking water in a recent peer-reviewed study. So, what are Nitrates & Nitrites, and why should you be concerned?

What Nitrates and Nitrites Are

According to the Water Quality Association, nitrates and nitrites are inorganic chemical compounds containing nitrogen and oxygen. They come from sewage, livestock manure, fertilizers, and the erosion of natural deposits (WQA). They can increase the risk of cancer, cause birth defects, affect the nervous system in adults, and cause blue baby syndrome in infants (WQA & EWG).

How to Filter Out Nitrates and Nitrites From Your Water

When looking to filter out nitrates and nitrites from your water, you’ll want to start with a water test. You can receive a free, no obligation, in-home water test from us, H2O Solutions, if you are a homeowner in Eastern Washington and Northern Idaho. We also have certified mail-in water tests available for purchase.

Once you know for sure what is in your water, you can make an educated decision on what water system would be best for your household’s needs. Consider an NSF-certified, American-made, low-maintenance system for best results. We offer EcoWater Systems for every household’s needs.
