Lead in Drinking Water

Lead is a naturally occurring element in our environment. Consequently, our water supply is expected to contain small, undetectable amounts of lead. However, most of the lead in household water usually comes from the plumbing in your own home, not from the local water supply.

Dangers of Lead

EPA estimates that more than 40 million U.S. residents use water that can contain lead in excess of EPA's Action Level of 15 ppb. Lead in drinking water is a concern because young children, infants and fetuses appear to be particularly vulnerable to lead poisoning.

A dose that would have little effect on an adult can have a big effect on a small body. On average, it is estimated that lead in drinking water contributes between 10 and 20% of total lead exposure in young children. All kinds of water, however, may have high levels of lead.

Lead Prevention

We maintain our drinking water supply at an optimum pH and mineral content level to help prevent corrosion in your home's pipes.

To reduce lead levels in your drinking water you should flush your cold-water pipes by running the water until it becomes as cold as it will get (anywhere from 5 seconds to 2 minutes or longer) and use only water from the cold-water tap for drinking, cooking, and especially for making baby formula. Hot water is likely to contain higher levels of lead.
