Cyanotoxin Monitoring Program
The summer of 2024 marks the tenth year of DWGPD's voluntary cyanotoxin monitoring program for public drinking water systems. This program offers no-cost analysis of raw and finished water for microcystin (a potent liver toxin produced by some species of cyanobacteria) to surface water systems across the state. Samples are analyzed on a weekly basis from July to early November by the Vermont Agriculture and Environmental Laboratory (VAEL).
