Why Test for Lead in Drinking Water
Unless you test for it, there’s no way of knowing if lead is in drinking water.
Children can come in contact with lead in many ways. Lead exposure poses a special risk to young children because they absorb lead into their systems more easily than adults do. Lead can slow down growth, impair development and learning, and can cause behavior problems.
While a major source of lead exposure in Vermont children is paint, lead in older plumbing and fixtures can add to a child’s overall lead exposure. Plus, water that sits in lead plumbing and fixtures when it's not being used likely contains higher levels of lead. This is why it's important to make sure lead levels in drinking water are as low as possible.
Vermont's Lead in Drinking Water Testing Law
To address these risks, Act 66 (2019) requires all Vermont school and licensed or registered child care providers to test their drinking and cooking water for lead according to the schedule in the rule. 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 fixture out of service and take steps to eliminate or reduce the amount of lead to below 4 ppb.
Act 66 is Vermont's state lead testing program for schools and child cares. The Lead and Copper Rule is a federal regulation established by the Environmental Protection Agency (EPA). Under Act 66, all schools and child cares must test their drinking water for lead every 3 years. Schools and child cares required to test under the Lead and Copper rule must also follow requirements for Act 66 testing.
See the table below to understand the differences between these regulations.

Act 66 | Lead and Copper Rule | |
---|---|---|
Who needs to test? | All schools and child cares in Vermont must test their drinking water for lead every 3 years. | Some schools and child cares on private wells may need to test for lead and copper. |
What taps do I have to sample? | All taps used for drinking and cooking are sampled and tested for lead only. | A select number of taps depending on size of the water system and testing history. |
How many samples do I have to collect per tap? | Two samples (first draw and flush) are collected at each tap in 250 mL bottles. | One first draw sample is collected in a 1-liter bottle at each tap. |
When is action required? | Any result at or above 4 parts per billion (ppb) must be fixed or permanently removed. | Take action if at least 10% of samples have 15 ppb for lead or 1.3 ppm for copper. |
