Lead in School and Child Care Drinking Water

In Vermont, lead in drinking water at schools and child care facilites falls under several regulations. A school or child care facility that has its own well and water treatment and is a public water system is regulated under the Lead and Copper Rule. A school that gets water from a community water system is not sampled as part of the community water system's LCR compliance testing, which prioritizes residences.

Imported Bottled Water (Non-VT Water Sources)

If the bottled water system is in another state or country (Imported bottled water system), a statement from the appropriate regulatory agency with jurisdiction over the bottled water system indicating that the facility has been approved to bottle or package water for human consumption shall be submitted. This approval may be in the form of a copy of a certificate, license, permit, or a letter of approval from the agency.

What are Cyanobacteria?

Magnified cyanobacteria

Cyanobacteria are photosynthesizing bacteria that may produce cyanotoxins that can cause illness to exposed human and animal populations.   A bloom is a visually identified concentration of cyanobacteria that discolors the water.  Cyanobacterial cells may be found at the water surface, at a defined depth, or present throughout the water column. 

Cyanotoxin Monitoring Program

Summer 2022, marks the eighth year DWGWPD is collaborating with the Vermont Department of Health (VDH), to offer at no cost cyanotoxin analysis of raw and finished water for the 22 Lake Champlain-sourced public water systems for 12 weeks (July through September). This years samples will be analyzed by Vermont Agriculture and Environmental Laboratory (VAEL).

Water Quality Monitoring

All public water systems must perform water quality monitoring to demonstrate that the water provided to customers is safe to drink. The kinds of samples that are required, the number of samples that are required, and the frequency of collection are based on the water system type, population, treatment, and water quality history.  Water quality monitoring requirements for TNC water systems can be divided into two general categories:  source permitting water quality monitoring and routine water quality monitoring.
