Chemicals in the Water

Benefits to Filtering Your Water

January 6, 2016

Here’s some helpful information from, “Ask Well.”   Health questions answered by Times journalists and experts.

Should you filter your water?

The short answer is yes. While the Environmental Protection Agency regulates municipal tap water and sets legal limits on certain contaminants, and most water utilities generally stay within these limits, “some of the legal limits may be too lenient,” said Paul Pestano, a research analyst with the Environmental Working Group. And more than half of the chemicals found in municipal water are not regulated.

Using the right water filter can help further reduce pollutants like lead from old water pipes, pesticide runoff in rural areas and byproducts of chemicals like chlorine that are used to treat drinking water. Radon, arsenic and nitrates are common pollutants in drinking water, and trace amounts of drugs including antibiotics and hormones have also been found. Certain filters may help remove these impurities as well.

But water contaminants and water quality vary from one local water utility to another, so you want to purchase a filter that is effective at capturing the right contaminants.

You can request a copy of your water utility’s annual water quality report – called a right-to-know or consumer confidence report — to find out which contaminants in your local water are of concern. Some utilities will also run a free lead test on your tap water.

You can then choose a filter that is certified by NSF International, an independent public health organization that assesses products. (All friendsofwater filters are certified).
