Cyanotoxin Monitoring Program

In Summer 2017, DWGWPD collaborated again with the Vermont Department of Health (VDH), to offer at no cost cyanotoxin analysis of raw and finished water at the VDH laboratory for the 22 Lake Champlain-sourced water systems for 12 weeks (July through September).

Previous Cyanotoxin Monitoring Program Data:


As part of this effort, Vermont water suppliers have attended cyanobacteria training developed for the summer volunteer monitors to learn how to visually assess their raw water source for the presence of cyanobacteria.   All drinking water facilities on Lake Champlain receive weekly email updates on cyanobacteria populations through the summer cyanobacteria monitoring program. This program is a collaborative effort between VDH, DEC, and the Lake Champlain Committee (LCC). The VDH Cyanobacteria Tracker allows for bloom identification in Lake Champlain.
