Read MoreCYANOBACTERIA AND CYANOTOXINS IN WATER
Over the past decade, cyanobacteria blooms have emerged as an important issue in the water and wastewater industry. Tory Colling, Scientist, explains what water professionals ought to know about cyanobacteria and cyanotoxins in water:
1. What are cyanotoxins?
Cyanotoxins are produced by some species of cyanobacteria or as commonly known as blue-green algae. These toxins are typically stored inside the cells, but when cyanobacteria cells degrade, the toxins are released.
Cyanobacteria are microscopic bacteria that have some plant-like characteristics. They are commonly called “algae blooms” in the media.
2. Where are they found?
Cyanobacteria naturally occur in freshwater. In fact, they contribute oxygen in our atmosphere. When conditions are favourable, such as warm temperatures and nutrient-rich, shallow and stagnant waters, cyanobacteria can form blooms. Cyanobacteria blooms are made up of densely-populated cells that form discoloured water, which is often described as pea soup or spilt paint with an oily appearance.
Certain cyanobacteria can produce by-products, known as cyanotoxins. When these cyanobacteria cells form a bloom, large amounts of cyanotoxins can be detected.
3. What are the health concerns?
Health concerns can range from liver toxins, neurotoxins, tumor-promoting effects or skin irritation. There are different types of cyanotoxins and each type has different health concerns. The most common cyanotoxin is called microcystin. Microcystin is a liver toxin and can cause tumor-promoting effects.
4. What are some strategies to control cyanotoxins?
Reducing nutrient inputs to source water or effective reservoir/watershed management are long-term strategies to control cyanobacteria and cyanotoxins.
5. How can cyanotoxins be removed from drinking water?
For larger municipal systems, combining effectively operated drinking water treatment processes can provide a multiple barrier to remove intact cells or released cyanotoxins. Some drinking water treatment processes, such as coagulation, flocculation and sedimentation or flotation, are capable of removing intact cyanobacteria cells. While other drinking water treatment processes, such as chlorination or ozonation, are capable of degrading released cyanotoxins, provided there is enough disinfectant concentration and contact time with the disinfectant.
Some very small or private drinking water systems may only rely on point-of-entry (POE) drinking water treatment units. If these private drinking water systems suspect a bloom in the water supply, it is recommended to contact the local health unit and use an alternative water source. Very limited POE treatment units are certified to specifically remove cyanotoxins. However, in 2019, the National Sanitation Foundation (NSF)/American National Standards Institute (ANSI) updated NSF/ANSI Standard 53 to include a protocol to test activated carbons filters to reduce microcystins.

Drinking Water Resource Library FAQ’s
Are you looking for reliable information on drinking water? Laura Zettler, Drinking Water Resource Coordinator, describes what you can find on the Drinking Water Resource Library.
1. What is the Drinking Water Resource Library?
The library is an online database of resources and website links providing information relating to drinking water. We provide this service to the operators, owners, inspectors and decision makers of water treatment systems and to the public. It is available online free of charge to anyone at any time.
2. What topics are covered?
Any resources that relate to drinking water quality or common issues found in Ontario are collected. We have curated groups for the most popular searches, making it easier to browse. These topics include regulatory guidance, cyanobacteria (blue-green algae), arsenic, lead, legionella and microplastics, to name a few. We also have a new folder, being updated daily, featuring resources relating to the current coronavirus pandemic.
3. How many resources are there?
Currently there are over 5,000 resources available for browsing but we continue to add new or relevant information every day.

Pilot Testing At WCWC
Are you curious about pilot testing? Devendra Borikar, Technology Demonstration Lead, and Jeff Avedesian, Acting Scientist, answer common questions about WCWC’s pilot testing program:
What is pilot testing?
A WCWC pilot project is a small-scale practical study conducted in order to evaluate feasibility, duration, or performance of a water treatment strategy and its effect on water quality. This can include bench or pilot-scale projects that may address health based, operational, or aesthetic water quality parameters.
What kind of projects have you done in the past?
WCWC has completed pilots that addressed cyanotoxins and cyanobacteria, arsenic, manganese, trihalomethanes, haloacetic acids, aluminum, dissolved organic carbon, chlorine, ammonia, hydrogen sulfide, iron, and sulfates using various specific strategies. WCWC can also provide information to owners, operators and other decision-makers in the form of a literature review for the purpose of making educated and informed decisions.
Is the work done in Walkerton or at my site?
The work can be completed either on-site or at the WCWC Technology Demonstration Facility depending on site-specific conditions.
What do you do with the results?
WCWC provides the owner and operating authority with preliminary data throughout the pilot, a detailed report and treatment recommendations. With the permission of the client, WCWC may choose to present the study at conferences and tradeshows, and may include results from the project in future training materials.
To learn more about WCWC’s pilot testing services, please visit wcwc.ca/pilottesting or contact Devendra Borikar at dborikar@wcwc.ca or 1-866-515-0550 ext. 313.
