PCWS Water Quality Monitoring - Cyanobacteria (Blue-Green Algae)

The events of Toledo, Ohio last summer have increased the awareness of the potential health risks due to cyanotoxins.  In response, in the summer of 2015, DWGWPD is collaborating 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--beginning on July 6th.  Results will be posted below on Thursdays for the program's duration.

In addition, all drinking water facilities on Lake Champlain receive weekly email updates on cyanobacteria populations through the summer cyanobacteria monitoring program.  VT water suppliers have attended the cyanobacteria training developed for the summer volunteer monitors to learn how to visually assess their raw water source for the presence of cyanobacteria.  They have also established a practice which specifies protocols to be used when responding to a cyanobacteria bloom.  Each year, a contact list of state personnel who can assist with identification of algae and/or toxin testing is provided to the facility managers to improve response time should a bloom develop in the vicinity of a water facility.  For more information, contact Heather Campbell, Blue-Green Algae Coordinator at 802-585-4893.
