New Drilled Well Testing: What You Need to Know

In April 2019, a new Vermont law passed requiring testing of new groundwater resources for single-family residences. The requirement is in the Department of Environmental Conservation (DEC) Wastewater System and Potable Water Supply Rules (see the Water Quality section on page 194). Note that the Rules also talk about other situations when a groundwater drinking water source serving a single-family residence or other building must be tested.

Lead Testing of Drinking Water in Schools and Child Care Facilities 2019-20

Many Vermont schools and childcare facilities are in older buildings, which means they are more likely to have lead in their plumbing. Because there is no safe level of lead in the body, and young children absorb lead into their systems more easily than adults do, it's important to ensure 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.

Lead Testing in Drinking Water - What Child Care Providers Need to Do

Due to the State’s COVID-19 response:

Unless otherwise instructed, child care providers should not collect water samples for lead testing at this time. This includes testing for the first time, post-remediation follow-up testing, or diagnostic sampling. If you already have your bottles and instructions, please hold onto them.

See additional information on lead testing during the COVID-19 pandemic.

Radon in Drinking Water

Radon is a naturally occurring radioactive gas. Radon may be present in both soil and water. Soil is the most common source of radon in your home. Well water that contains radon may increase the level of radon in a home. Activitieslike taking showers, doing laundry, or running the dishwashercan release radon into the air.

Hardness in Drinking Water

Hardness was originally a measure of the capacity of water to react with soap, where hard water requires more soap to create a lather.

Water described as “hard” contains high amounts of naturally occurring dissolved calcium and magnesium. Total hardness is the sum of the calcium and magnesium concentrations, both expressed as calcium carbonate, in milligrams per liter (mg/L). You can determine your water’s hardness based on these concentrations of calcium carbonate:
