The Vermont Department of Health Laboratory (VDHL) works closely with state offices and public water suppliers to monitor Lake Champlain and drinking water supplies for potential blue green algae toxins. Laboratory testing of water samples can confirm whether or not a bloom is toxic.
Testing is offered to the public during the time when potential blooms are expected, usually Memorial day to Labor day.
VDHL testing capabilities:
- Screening test - Microcystin ELISA
- Confirmation test - Anatoxin-a LC/MS/MS
