The Turner Designs CyanoFluor Handheld HAB Indicators is a field-portable fluorometer that can quickly estimate the abundance of cyanobacteria in a mixed algal population using PC (phycocyanin) to CHL (chlorophyll) ratios. Monitoring PC to CHL ratios over time enables users to predict the onset of HABs and leverage resources to mitigate their harmful effects.

CyanoFluor is factory-calibrated, meaning no calibration is required; RFU values can be correlated to µg/L using conversion coefficients. Solid-state optoelectronics ensure long-term instrument stability. CyanoFluor’s intuitive functions, small size, and internal data storage make it an ideal field instrument for HAB monitoring.

Questions & Answers
How are RFU vales correlated to ug/L for the CyanoFlour?
The raw fluorescence units (RFU) can be correlated to µg/L by obtaining a sample from the local water body and determining the RFU value (CyanoFlour) and the actual chlorophyll µg/L value (EPA method 445.0). From there, a conversion factor can be created using the previously recorded data.

Data-Driven Decisions: Tracking Sediment during the Klamath Dam Removal

The largest dam removal in U.S. history, the deconstruction of the Klamath Dam is slated to begin this summer. The project includes four dams along the Klamath River with the first and smallest dam, Copco #2, scheduled for removal first. As each of the dams are torn down, scientists and consultants will keep a close eye on the state of the Klamath River downstream to assess the impact of undamming the river. Shawn Hinz, managing partner and environmental toxicologist with Gravity Consulting , has been involved with the Klamath Dam project for over a decade. Hinz was a part of these earlier steps, representing the academic stakeholder position as a graduate student sitting on a board of other stakeholders.

From the Tap: Source Water Monitoring for Public Health

In regions with historically secure access to clean drinking water, few think about the work that goes into ensuring that the water they fill their cups with is safe. In reality, millions of dollars are invested in the infrastructure, equipment and teams involved in converting source water into drinking water. While all the work that goes into providing clean water often goes unnoticed, analysts like Michele Gilkerson, a water research analyst with the City of Columbus Division of Water, know exactly how much goes into securing safe water for millions of people. Gilkerson started with Battelle Memorial Institute in 1991 in their water ecology section. There, she saw how interesting source water monitoring could be, even though it isn’t often spotlighted in the environmental sector.

Choosing the Right Water Quality Monitoring Systems Is Crucial for Stantec Inc.

Data is king when it comes to water quality monitoring. It is not merely the type of data being collected that matters but also how that data is stored, processed and presented. When Joseph Kamalesh, a project manager with  Stantec Consulting Services Inc. , needs to find the right equipment for large client-based projects, he knows to keep these factors in mind. Joseph has a background in water quality and water flow monitoring instrumentation, which he continues to focus on at Stantec. During college and his early career, Joseph gained experience with water instrumentation, consisting primarily of on-site wastewater sampling and sampling small systems.
