Confederated Tribes of Coos, Lower Umpqua, and Siuslaw Indians Integrate FlowCam into Environmental Stewardship Programs

The Confederated Tribes of Coos, Lower Umpqua, and Siuslaw Indians (CTCLUSI) recently received long-awaited funding to purchase a FlowCam Cyano instrument, after first learning about FlowCam at an east coast workshop a few years ago. CTCLUSI makes up three tribes (4 bands) who all reside in close proximity to one another along the Coos River Tributaries in Oregon. According to the CTCLUSI website:

Community Groups Take HAB Monitoring Into Their Own Hands, Recognize Need for Formal Strategic Guidelines

Harmful algal blooms can have a detrimental effect on the environment and on human and animal health. As a result of climate change, water utilities are experiencing these events with increasing frequency. Historically, many water monitoring agencies have not had a plan in place to proactively monitor for cyanobacteria, but rather found themselves reacting to the effects of a bloom after the fact.

Last month, the US EPA released a report that addresses concerns within the agency about the lack of a cohesive, agency-wide plan to monitor freshwater bodies for harmful algal blooms (HABs):

New FlowCam Technical Notes: Using Preservatives with Phytoplankton Samples

Aquatic scientists often need to store natural samples for a period of time before processing them using FlowCam. There are multiple preservatives available for this purpose. Glutaraldehyde is a
popular choice of preservative because it will preserve pigment autofluorescence, and therefore allows the use of FlowCam's "Trigger Mode" to automatically distinguish cyanobacteria from other algae, and reduce images of detritus and other non fluorescing particles. Another preservative often used is Lugol's solution, which does not preserve fluorescence, but is less toxic and requires less stringent storage conditions.

Greater Cincinnati Water Works Uses FlowCam Cyano to Monitor Source Water

Applications Scientist, Kay Johnson has spent this week in Cincinnati training new FlowCam users at the Greater Cincinnati Water Works (GCWW) on their new FlowCam Cyano. GCWW is located on the Ohio River across the water from Kentucky. They will be using the FlowCam Cyano to count and categorize cyanobacteria and other phytoplankton populations both before and after treatment.

Using FlowCam and Machine Learning to Classify Microcystis at the Genus and Species Levels

The FlowCam was recently used by a team led by Natasha Barteneva of Nazarbayev University to develop a method for the classification of Microcystis colonial morphospecies in samples obtained from a long-term mesocosm experiment (the AQUACOSM Lake Mesocosm Warming Experiment).

City of Worcester Will Integrate FlowCam Cyano for Proactive Water Quality Monitoring

The City of Worcester, MA has purchased a FlowCam Cyano to help expand a volunteer water quality monitoring program. The effort is led by Jacquelyn Burmeister, a senior environmental analyst with the City's Lakes & Ponds Program. Together with several other local watershed associations, she helped organize a regional cyanobacteria monitoring collaborative that has recruited dozens of volunteers to help expand cyanobacteria monitoring in the area's recreational waters.

Central Arkansas Water Named Recipient of the First FlowCam Drinking Water Equipment & Travel Grant

This year we introduced a new grant program for US and Canadian water utilities: The FlowCam Drinking Water Equipment and Travel Grant Program. The program is designed for water utilities to advance their science by helping them reduce labor hours, detect nuisance algae, and predict harmful algae blooms or taste & odor events.
