If you knew what was in your water, you'd do something about it.

Homes in and around Potomac, including those in Travilah, Rockville, Bethesda, and Glen Hills, receive treated municipal water through the Washington Suburban Sanitary Commission (WSSC).

There are thousands of potential contaminants that can be found in typical municipal water systems, and only a portion of these are actively regulated. In fact, there are only approximately 90 contaminants that have established primary standards.

There are so many contaminants that it’s hard for water treatment plants to keep up. So, while your water quality meets regulations, that doesn’t mean it can be considered clean. Water is susceptible to contamination even after leaving the municipal treatment facility. The only way to truly know what is in your water is to have it tested.

Water treatment plants do their job of meeting EPA quality standards for water at the time it leaves the plant. But, that’s where the control stops. There are a range of factors that can affect the water quality and contaminant level as it makes its way from the utility lines to your faucets.

It’s time to test your home’s water to find out what your family is drinking.
