It’s a frightening realization that the drinking water we ingest every day could contain elements that cause cancer.

Studies conducted by the Environmental Protection Agency (EPA), and further investigated by the Natural Resource Defense Council (NRDC), estimate that more than 34 million Americans are drinking tap water supplied by water sources that contain dangerous levels of Arsenic.

According to a study conducted by the National Academy of Sciences, consumption of drinking water containing arsenic can cause bladder, lung, and skin cancer. There’s also evidence that it can cause damage to the central and peripheral nervous systems and lead to reproductive problems.

You’re probably wondering how you can find out if your drinking water contains arsenic. Local water utilities are required by all to inform consumers of all contaminants and toxins found in their drinking water. The easiest way to get accurate information is to contact your local water supplier and request a report.

You can also get more information from the National Resource Defense Council.

Many people resort to drinking bottled water under the assumption that it is cleaner than the water that comes from the tap in their home. In another study conducted by the NRDC, over 100 brands of bottled water were tested for arsenic and other contaminants.

They found that over one-third included synthetic chemicals, bacteria, and arsenic.

The best way to ensure that your drinking water is clean and healthy is to filter out the contaminants yourself. Reverse Osmosis (RO) systems can be installed for a low cost directly into your home plumbing. These systems draw out a large number of contaminants, including a number of forms of arsenic.
