Is Your Plumbing System Adding Lead to Your Drinking Water?

Even though Aquarion water is lead-free as it leaves our treatment facilities, your home’s plumbing system can introduce it into the water coming from your tap. Many faucet fixtures contain a high percentage of lead, and the plumbing in houses built before 1988 can contain lead solder or lead piping. If lead from these sources leaches into your drinking water, it can present a health hazard.

Lead can delay the physical or mental development of infants and children who drink water containing excess lead. It also could affect attention span and learning ability among members of this vulnerable group. What’s more, adults who drink water with excess lead over many years could develop kidney problems or high blood pressure.

Have Your Tap Water Tested

As part of Aquarion’s water treatment processes, we adjust the acidity of our water to neutral, and we also add a phosphate-based corrosion inhibitor to help reduce the amount of lead that may be introduced into the water from lead materials in plumbing systems. These steps may not be effective in all cases, though, so if you live in a house built before 1988 we urge you to have an independent testing lab check the water coming out of your taps to see if lead is present.

If you are concerned about elevated lead levels in your drinking water, you also may run your tap for 30 seconds to two minutes. This will flush out the lead that may have accumulated in water standing in your pipes for an extended period of time. (You can use the water you run for other household purposes, such as watering plants and cleaning clothes.)
