WCWC launched a new remote monitoring system. Geordie Gauld, Technician, tells us more about how the new system will assist with pilot testing projects to support water system owners, operators and operating authorities.
What exactly is the new remote monitoring system? How does it work?
Essentially, this is a small-scale Supervisory Control and Data Acquisition (SCADA) system with cellular connectivity. It operates on many of the same principles as the monitoring and control system at a full-scale water treatment facility. A simple programmable logic controller (PLC) will take in process signals from the pilot plant, including parameters like water pressure, flow, turbidity, pH, etc. Using these inputs, we can observe system statuses, compile datasets, and generate historical trends from right here at WCWC.
How will this benefit pilot testing projects?
It can be challenging to gather complete data from our pilot testing communities. Many are in remote regions and we cannot stay onsite for weeks to manually gather data. Operators are also very busy running their own facilities and don’t have the time to manually sample and collect the data we need and get it into our hands. This system will allow us to collect complete datasets with little to no input from operators. Complete data will lead to a more effective pilot testing process and allow WCWC and the facility owner to make more informed decisions regarding the direction of the pilot testing project, no matter where the owner’s plant is located.
Being able to view the status of the system in real-time will also allow us to confirm things are running as they should be. An undetected failure in the pilot plant can render large sets of data incomplete or inaccurate and delay the overall progress of the pilot testing project.
How is one monitoring system going to be effective for multiple pilot testing projects that may have many different requirements?
By reviewing the configurations of previous pilot testing projects, we were able to compile a list of modular hardware requirements we felt would be most useful. This allowed us to wire and pre-program the unit for common configurations with the ability to use or omit certain features as desired. This approach will allow us a great deal of flexibility working with different treatment strategies and arrangements. In our hardware selection we also allowed for several “spare” inputs which will allow us to expand our capabilities in the future.

WCWC has resumed in-person classroom training with a new COVID-19 Training Session Protocol to enhance safety for participants and instructors. Stephanie Meades, Small Systems Specialist, talks more about the new self-screening, physical distancing and disinfection measures.
What does self-screening involve?
Participants will be required to complete a self-screening questionnaire prior to the training session. Self-screening will include questions regarding COVID-19 signs and symptoms, travel history and contact with individuals with respiratory illness or a confirmed or probable case of COVID-19. If a participant does not pass the self-screening, they cannot attend the training session.
What can I expect at the training session?
Each training session will begin with a presentation regarding health and safety related to COVID-19. The instructor will attempt to maintain physical distancing at all times, but if it cannot be met for hands-on activities, Personal protective equipment (PPE) will be required.
Is PPE provided?
WCWC will provide masks, protective eyewear and hand sanitizer for participants. If a participant refuses to wear PPE when required, they will be asked to leave the training session.
Will there be any extra disinfection measures in place?
Facilities will be cleaned and sanitized before and after the training session. Signs will be posted to ensure policies and procedures related to COVID-19 are communicated to all participants.
How many participants will be in each training session?
The number of participants will be restricted according to the size of the room to respect physical distancing requirements. If unregistered participants arrive, they will not be allowed to enter the training session.
A variety of training sessions across Ontario are now open for registration. For further information, or to register for any of WCWC’s upcoming training sessions, please visit wcwc.ca/registration or contact us at 866-515-0550 or firstname.lastname@example.org.Read More

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.Read More
