Why Test for Lead in Drinking Water

Lead is a highly toxic metal. There is no safe level of lead in the body. Exposure to lead can slow children’s growth, impair their development and learning, and cause behavior problems. Additionally, young children absorb lead into their systems more easily than adults do. 

Lead can get into drinking water from plumbing and fixtures, so it's important to make sure lead levels in drinking water are as low as possible. Fixing a lead in drinking water problem is often easy and low cost. Solutions can include replacing plumbing fixtures, removing redundant or seldom-used fixtures, and encouraging the use of centrally located, well-maintained bottle fill stations.

First Round of Testing

Act 66, passed in 2019, requires all Vermont school districts, supervisory unions, independent schools and child care providers to test their drinking and cooking water for lead. If lead is found at or above the action level of 4 parts per billion (ppb), the school or child care provider must immediately take the tap out of service and take corrective action to eliminate or reduce the amount of lead to below the action level.

A bell with the word "update" under it.

The first round of testing was completed from June 2019 through December 2021. During this round, 98% of Vermont schools and child care providers tested over 15,000 taps used for drinking and cooking and took steps to ensure lead levels were below 4 ppb. Here are some key findings:

  • One out of every five drinking water taps tested had elevated levels of lead. 
  • Sinks were the most common tap tested and had among the highest lead levels.
  • Bottle fillers had the lowest lead levels. 
  • Lead was more frequently found in the water fixture rather than the plumbing.
  • Costs were less than $500 for 90% of the fixtures that needed to be replaced.

There will be more rounds of testing. Taps at schools and child care facilities will need to be tested every three years according to the schedule in the rule

Pilot Project

The Health Department, Agency of Natural Resources and the Agency of Education led a joint project from November 2017 to March 2018 to gather information about lead levels in drinking water of Vermont schools.

Frequently Asked Questions
Why is lead a concern?

Exposure to lead is a public health concern in Vermont. Lead is a highly toxic metal that is harmful to human health. It has been commonly used in many household, industrial and automobile products — such as paint, solder, batteries, brass, car radiators, bullets, pottery, etc.

There is no safe level of lead in the body, but lead poisoning is preventable. Lead can harm anyone, but children under the age of six are at special risk. Children are most susceptible to the effects of lead because their bodies are still developing and they absorb lead into their systems more easily than adults do. Even low blood lead levels in a child’s body can slow down growth, impair development and learning, and can cause behavior problems. Most children who have lead poisoning or high levels of lead exposure do not look or act sick.

When are schools and child care providers required to test?

The first round of testing was completed on December 31, 2021. See the results.

Schools and child care providers need to repeat the testing process every three years. Ongoing testing is important because lead levels at the tap can change due to water quality changes and the breakdown of plumbing components over time. Facilities are encouraged to strive for the lowest possible lead levels, ideally below 1 ppb. If a tap tests lower than 1 ppb for three testing cycles, that tap is not required to be tested again.

What is the Vermont health advisory level and what does it mean?

Because there is no safe level of lead in the body, Vermont has set a health advisory level for lead to the lowest level that can be detected, which is 1 ppb. This level is also consistent with the American Academy of Pediatrics recommendation that taps in schools should not have lead levels above 1 ppb.

Should children have their blood tested for lead if lead has been detected in the drinking water at their child care facility?

In short, probably not.

Any time a child’s blood lead test shows a detectable level, the Health Department tries to identify the source of the exposure. By testing all school and child care facilities and requiring remediation, we will be certain that any exposure from drinking water at the facility has been identified and reduced.

When deciding whether to test a child for lead in response to a school or child care provider’s water test results, it is important to understand that the possible exposure to lead from drinking the water at a school or child care facility may only be a part of the picture. There are other possible sources of lead (see the next question), and the amount in drinking water can add to a child's overall lead exposure. We also can’t know how much water an individual child drank at the school or child care facility, so the amount of exposure is unknown.
All children should be screened for lead at ages 1 and 2 by their health care provider. If you have additional questions, call the Healthy Homes Lead Poisoning Prevention Program at 802-863-7220 or 800-439-8550 (toll-free in Vermont), or talk to your child’s health care provider. Learn about lead hazards and how to prevent lead poisoning.

Are there other ways children can be exposed to lead?

Exposure to lead is a public health concern in Vermont. Possible sources include dust from chipping or peeling lead-based paint, toys, keys, jewelry, pottery, dishes, contaminated soil, old plumbing pipes and fixtures, imported candy and foods, and antique, vintage and salvaged goods. While a major source of lead poisoning in Vermont children is paint, lead in plumbing pipes and fixtures can add to a child’s overall lead exposure. Learn about lead hazards and how to prevent lead poisoning.

The Health Department encourages all homeowners — on town water or private wells — to test their drinking water for lead. The Health Department Laboratory offers the first draw and flush test kits for $12 each. Call 802-338-4724 or 800-660-9997 (toll-free in Vermont).
