Straight From The Chair

Are We Ready?

ver the years I’ve heard many stories of how people became active in the AWWA. I’m fascinated by these experiences and often use the question, “How did you find yourself to be in the water industry?” as an ice breaker. Few of us planned to be doing what we do. Many stories have similarities, but each is unique. Take a minute and reflect on your water story. Who encouraged you to become a member? Why are you reading this newsletter? What benefits do you receive from your participation, and how could they also benefit your peers that aren’t yet aware? I reflected on my water story after the passing of the gavel at the One Water Conference. It’s different from yours but I bet there is at least one similarity: we just showed up. That’s step one. Walking the halls at One Water, I was greeted by a popular question regarding filling the Chair position, asked by many influential leaders. “Are you ready?” My first thought was, “What did I just sign up for?” but then I reflected on our recent momentum and our refreshed strategic plan. I realized it’s not a question for me, but for us. Are we ready? Are we ready to address diversity, equity and inclusion? Are we ready to address the next rounds of regulation updates? Are we ready to engage our members differently? Are we ready to tackle what training and development means today? In the future? I think the answer is yes. But it’s not me alone. It’s not the Chair, Governing Board, Districts, or Committees alone that are responsible for driving this strategic plan. It is us. The Ohio Section of American Water Works Association, and all of us it encompasses, have the voice to influence change. The Ohio Section is in good hands because of all of you. RETURN TO TABLE OF CONTENTS

MIKE GIANGIORDANO Jacobs

You’ll see some changes as the board rolls out new initiatives developed from the Section’s Strategic Plan. More updates will follow in later issues and communications. In the meantime, please stay active. Reflect on your water story, and let us maintain our existing relationships, be open to new ones and encourage a new wave of water professionals to discover their water story and experiences.

Director’s Report

Being the Best We Can Be

s we begin to wrap up another year of doing business, we naturally find ourselves thinking about the past year, what went well and what we could have done better. We also start planning for the new year to come. While planning, hopefully you realize the invaluable benefit of attending and participating in in-person events sponsored by Ohio AWWA. The networking of peers and casual conversations held during plant tours and workshop breaks are instrumental to personal and professional growth. Although there is a time and place for remote learning, nothing can replace in-person learning opportunities, in my experience. This time of year is also when budgets are established. Please make sure to include funds for both your AWWA membership, and for travel and training for yourself and your fellow employees. Investing in employee professional growth through AWWA sponsored events is some of the best money your organization will ever spend. The fall season is also a time when we contemplate our approach to business in the coming year. With difficult

TYLER S. CONVERSE

challenges at hand, such as elevated inflation and borrowing costs, increasingly stringent and costly regulatory requirements, difficulty hiring and retaining top employees, and affordability issues, just to name a few, we no longer have the luxury of ignoring industry ‘best business practices’ for our organizations. We must continue to become more efficient and effective with limited resources available to us. Is your utility positioned to meet these challenges? How would you know? One way to find out is to peruse the findings of AWWA Water 2050 project, available online on the AWWA website. There, you can easily review the think-tank summary results in the categories of Sustainability, Technology, Economics, Governance, and Social/Demographics. By comparing your business’ approach to that of subjectmatter experts in these reports, you can gain invaluable insights into your organization’s position in the market. I encourage you to do so as you consider your pathway into 2024.

‘Take one with you’ – The Power of Mentorship and Why We Need to Harnwess It in the Water Industry By Megan Shortridge, Ohio Environmental Protection Agency, Division of Drinking and Ground Waters The contents of this paper/publication are the personal opinions of the author and may not reflect the policy or procedures of the Ohio Environmental Protection Agency.

In a world where we are seeing unprecedented turnover in the water industry due to retirements, the importance of mentorship cannot be overstated in recruiting and retaining the next generation of water professionals. In fields where minorities have been historically underrepresented, mentorship plays a pivotal role in empowering individuals, bridging gaps, and fostering an environment of collaboration. Mentorship does not have to be complicated. It is something each of us can put into practice today, no matter where we are in our career. This is where ‘take one with you’ comes into play. Whoever you are, wherever you are going, always look around and think about taking at least one other person with you, as often as you can. Are you part of an interesting committee centered on new technology in the water industry? Take a co-worker with you to observe. Are you going out to dinner with colleagues during a conference? Grab a new or younger colleague and bring them along. Did someone make an insightful observation, a great presentation, or finish up a challenging project? Say something kind! Your words may be just what they need to hear. During OneWater this year, Women in Water put together a fantastic Women’s Networking Event. During that event, I was saddened by the notion that some individuals may contribute to an unhealthy (and sometimes downright toxic) RETURN TO TABLE OF CONTENTS

work environment because they themselves had a hard time at that stage in their career. We’ve all overheard someone say, “Why should the new person have it any easier when I had it so tough?” We need to shake off such notions and encourage professional kindness and empathy through mentorship. We should always strive to make the industry better by making our individual workplaces better. Only through a collaborative spirit can we reinforce the idea that success is not a finite resource. We need to create workplace cultures that celebrate the idea of ‘taking one with you’: a culture that celebrates collaboration and lifting others up, regardless of sexuality, gender, work experience, or background. This mindset shift is crucial to the future of diversity in the water industry. When we actively seek opportunities to support others, we foster an environment where achievement is celebrated collectively, rather than isolating individuals. If we embrace this shift, we can create work environments we all feel good about being in. Looking around the room right now, or glancing through your emails and messages; how can you ‘take one with you’ today? Megan Shortridge is an active member of Ohio Section AWWA’s Young Professionals and Diversity and Inclusion Committees, and on the Diversity in Water Speaker Series organizing team. She co-founded the Diversity in Water Speaker Series to help us all ‘take one with you.’ FALL/WINTER 2023

2023 JOINT CONFERENCE

ver 1,900 water and wastewater professionals from around Ohio and the Great Lakes region attended the 2023 One Water Conference in Columbus this past August. Conference attendees participated in over 80 educational opportunities, six networking events, and two regulatory updates. Preconference events included a new community outreach at the Hoover Dam in Westerville, as well as the annual Golf Outing. This year’s Women in Water Networking Event featured a panel that discussed ways to help more women find a career in the water industry and attracted over 100 diverse conference participants. Planning has already started for 2024: we hope to see you next year at the Kalahari Resort in Sandusky, OH, August 5–8.

OPERATOR COMPETITIONS 2023 The Operator Competitions at the One Water show in Columbus were very exciting this year. The competition for Pipe Tapping, Hydrant Hysteria, AWWA Meter Challenge, and Top Ops was strong. A very special thank you to Chris Briggs, Patrick Crumley, Jimmy Roberts, Daniel McClain, and Marvin Banks from Columbus Water, along with Shawn Justus of Cleveland Water, Lenny Solomon of Clow Valve, and Zach Walker of Kennedy Valve for their help in coordinating the competitions. Without their willingness to go above and beyond, these events would not have been possible. 16

FALL/WINTER 2023

PIPE TAPPING This year we had four men’s teams competing: Cincinnati, Cleveland, Columbus, and Lima. The Columbus team, consisting of Coach Patrick Crumley, Cranker Daniel McClain, Feeder Chris Briggs and Copper Jimmy Roberts, defended their 2022 title, but not without close competition and a little bit of controversy. During Cleveland’s first tap, the water to the convention center was shut off due to a leak. Their raw time of 2:32.10 became 2:50.10 after assessed penalties and they had a compelling argument that the lack of water impacted their run. The judges conferred and offered Cleveland the opportunity to re-tap but due to the physical demands of tapping pipe, they opted to conserve their energy. The Columbus team snapped their tapping bit during their first run so it all came down to their second and final run where they posted a (winning) time of 2:13.12. Lima and Cincinnati put forth strong teams but had just enough hiccups to have them setting their

sights on next year. Shout-out to Cliff Shrive for being the MC. Full Results: Columbus – Daniel McClain, Chris Briggs, Jimmy Roberts, coach Patrick Crumley – 2:13.12 Cleveland – Ryan Powers, George Black, Colin Powers, coach Mark Shepherd – 2:50.10 Cincinnati – Milton Davis, Ron Payne, Shawntez Scott, coach Tony Jones – 3:58.43 Lima – Brad Hutchinson, Derek Lingenfelter, Michael Coffey, coach Larry Huber – 4:06.81 A special thanks to our sponsors A.

AWWA METER CHALLENGE As we have done in the past, District Competitions for the AWWA Meter Challenge (formerly Meter Madness) took place at the Southern Ohio Utilities EXPO in Wilmington, and the Northern Ohio Water & Waste Water EXPO in Wooster. From those competitions, we get the four District winners who take on the reigning Champion at our Conference Competitions. The reigning state champ, Paul Tucker of Lima Water, took on NW District champ Chuck Collins of Lima, NE champ Dave Marinella of Cleveland Water, SW champ Ray Smith of Fairborn, and SE champ Troy Snider of Columbus. The competition features two rounds, with assembled meters being tested for leaks, loose bolts, etc. Round 1, Dave Marinella posted a raw time of 34.59 but was assessed 10 seconds worth of penalties; his resulting 44.59 time only narrowly edged out Chuck Collins’ clean 45.29 run. Round 2 saw returning champ Paul Tucker’s raw time of 39.86 increase to 57.86 due to penalties and thus, Dave survived formidable challengers to claim the title. A special thanks this year to Badger Meters for sponsoring the Meter Challenge and providing all the practice and competition meters. Jeff Cunningham, of M.E. Simpson Co., helped coordinate the competition and test the meters. Full Results: Dave Marinella – Cleveland – 44.59 Chuck Collins – Lima – 45.29 Ray Smith – Fairborn – 51.31 Paul Tucker – Lima – 57.86 Troy Snider – Columbus – 59.27

Advantages & Benefits of SpectraShield Reduces O&M Costs & Capital Expenses

As a result of the impervious nature of the SpectraShield Liner System, infiltration and ex-filtration is eliminated in structures. Operating and maintenance expenses are reduced, plant capacity is preserved, and plant expansion requirements may be delayed or eliminated.

Very Low Life Cycle Cost

As a result of the long life and competitive installation cost, the life cycle cost for the SpectraShield Liner System is very low. In many cases the ROI is under 24 months.

Helps Protect the Environment

Groundwater entering the system is reduced, allowing more to percolate to the aquifer. Reduced pumping requirements reduce energy use reducing the carbon footprint. SSOs (Sewer System Overflows) are reduced as infiltration is reduced.

Prevents Corrosion

The Spectrashield Liner System provides a protective barrier that prevents H2S and moisture from reaching the surface of the structure.

Rapid Trenchless Installation

The SpectraShield Liner System can be installed in a typical 7 foot deep manhole in about an hour without any excavation. The manhole may be returned to service immediately upon completion of the installation. An average sized pump station or wet well application takes about 2 days from start to finish. The pump station or wet well may be returned to service immediately upon completion of the installation.

Flexibility

The multi-layer SpectraShield Liner System is flexible, allowing it to handle the stresses associated with structure settling, traffic loading, and freeze thaw cycles.

Long Life

The SpectraShield Liner System has a design life of 100 years and comes with a 10 year manufacturer warranty. The first structures lined in 1993 are still in place, and in good condition.

Versatile

The SpectraShield Liner System may be used in a variety of structures, such as; manholes, lift stations, wetwells, large diameter pipes, box culverts, headworks, grit chambers, weirs, and package WWTPs.

Experience

Since 1993, in-house applicators, and trained certified licensees, have applied the SpectraShield Liner System in over 105,000 structures. Over 11 million square feet of the SpectraShield Liner System have been applied.

Cost competitive

The SpectraShield Liner System installation cost is very competitive with all other liners and coatings.

Battling Salt in Our Water If you had to guess… What if you were asked to guess the main contributor to salt contamination in water? Your choices are between agriculture and urban inputs in Ohio, you would think it has to be agriculture, right? Let’s see which is the answer.

RETURN TO TABLE OF CONTENTS

BACKGROUND The Hamilton to New Baltimore Groundwater Consortium consists of seven independent public and industrial water suppliers in southern Butler and northern Hamilton Counties, Ohio. Members include: • City of Hamilton • City of Fairfield • Butler County Water and Sewer • Molson Coors Beverage Company • Greater Cincinnati Water Works • Southwest Regional Water District • Southwestern Ohio Water Company

Combined, Consortium Members produce over 61 million gallons of groundwater per day for public and industrial water needs in most of Butler County, southern portions of Preble County, and northern portions of Hamilton County Ohio. The Consortium members pump groundwater from the Great Miami Buried Valley Aquifer (GMBVA). This groundwater resource is sensitive because it is an unconfined sand and gravel aquifer. To keep this water resource safe the Consortium implements a regional Source Water Protection Program. FALL/WINTER 2023

WATERFRONT

Two out of seven key components to the program are: Groundwater Monitoring Groundwater is monitored twice a year by collecting water samples from groundwater monitoring wells and analyzing the samples for certain water quality characteristics. Some wells within the Consortium’s network are sampled quarterly. Water levels are measured monthly from the network of wells around the region to ensure long-term sustainability of the resource. Quarterly sampling of the Great Miami River also takes place at several locations upgradient of the source water protection areas and within the source water protection areas.

This is carried out by one of the founding members of the Consortium, Greater Cincinnati Water Works. Education Outreach The Consortium has an extensive outreach and education program that includes many activities, such as the Children’s Water Festival, 5K Race for Global Water, Great Miami River Clean up, in partnership with Butler Soil and Water Conservation District. In 2014, Source Water Protection educational signs were placed in Fairfield, Ohio’s Waterworks Park to educate the public on the importance of protecting groundwater throughout the region and what residents can do to help keep our water safe from pollution.

RESEARCH A recent study conducted by GCWW was performed to study the impact of salt on groundwater. Increasing sodium and chloride levels can lead to salinization. Concerns associated with groundwater salinization are human health risks, pollution of our aquatic life and environment and corrosion of underground pipes and equipment. A potential contaminant source inventory was used to identify potential sources of salt in groundwater in the GMBVA. The general assumption was that increasing salinization in the aquifer is predominately anthropogenic. The regional study and groundwater monitoring conducted revealed that sodium and chloride concentrations are increasing in many areas in the GMBVA. The data gathered through the Consortium monitoring well network was used in a binary mixing curve comparing the well data to an established salt source program. Based on this graph and a few others, the chloride/bromide ratios have a consistent increase associated with input from halite most likely from deicers. A conclusion from the research is that communities should holistically balance public safety needs with water quality concerns to properly manage drinking water resources. ACTION As a protector of source water, the Groundwater Consortium started thinking of a plan to act on the recent research. We asked, what is a way for education outreach that is long-term and actively involves the community. Educational Signage First we started by expanding on a project already successful. The educational signage installed in Fairfield, Ohio’s Waterworks Park has been accessible to hundreds of park visitors over the past several years and has remained in great condition.

Adding another bike path sign educating about salt application and its risks was decided as the first step but not the last. An educational sign is a good way to provide information to the public but it is equally or more important to actively involve the public and enable them to take action. Salt Measuring Cups The City of Greater Sudbury began issuing free plastic cups to residents as a way to educate their community on how much road salt should be used. Each 12 oz cup has printed on the front that it can contain enough salt to cover ten sidewalk squares or 500 square feet. Using the cups, residents can measure the amount of salt used instead of overapplying. We intend to do the same in our area. Salt Watch Testing Kits Izaak Walton League of America has a salt watch program that provides salt watch test kits with four chloride testing strips. These strips are used to test chloride levels in waterways and the results can be submitted online to be added to a national database. RETURN TO TABLE OF CONTENTS

Bringing it all together An application for the Ohio EPA OEEF Mini Grant was submitted for $5,000. The project was presented as a two-step process beginning with the educational sign. The educational sign will be implemented first. Design of the sign will begin on November 5 and will use the research done this past year by Greater Cincinnati Water Works on the salinization of source water concerning the Great Miami Buried Valley Aquifer locally as well as other research more generally. The sign will go into detail what salinization is, what the general causes are, and how to take action to protect source water here locally. This sign will be accessible to anyone walking, jogging or riding along the bike path in Waterworks Park. This sign will also direct people to our website for additional information on the grant and the Groundwater Consortium. The second step is reaching out to homes in the local community informing them of the newly installed sign and offering to provide a salt cup and a chloride testing kit. This activity will be sending educational packages to homes located

in the neighborhoods surrounding Waterworks Park. Homeowners in the residential community near Waterworks Park will be made aware via letter, of the newly placed educational sign at Waterworks Park and will ask if they are interested in receiving more information and participating in a salt watch project. For those who say yes, they will be sent the cup to measure salt and the salt testing kit. The grant was approved and will begin October 4 and is expected to be completed by October 4, 2024. The success of the project will be measured by continued monitoring of salt levels in the aquifer sensitive region through sampling and the Izaak Walton League’s national database.

Diversity and Inclusion Update

One Water Conference Trish Harrison, D&I Committee Chair

n today’s interconnected world, the importance of diversity and inclusion cannot be overstated. These principles not only foster a more equitable society but also drive innovation and progress. OAWWA recognizes the significance of diversity and inclusion, and has taken active steps to promote these values. This was apparent at the One Water Conference held in Columbus, Ohio, August 21–24, 2023. The One Water Conference brings together professionals, experts, and leaders in water management, with this year’s conference being the largest to date with close to 2,000 attendees. One of the most visible ways that diversity and inclusion was promoted at the conference was through the address given by the keynote speaker, Mr. Donnell Duncan P.E., S.E. This approach ensured that attendees were exposed to the diversity and inclusion approach and its level of importance to the OAWWA. Mr. Duncan, senior professional structural engineer, engineering professor, author of the new book A New Mindskin, and widely respected speaker, shared a diversity and inclusion presentation that was easy to follow and relate to. His spouse, Dr. Angel Duncan, is an author, speaker, professor and entrepreneur. She has experience in the corporate, academic and nonprofit sectors in regard to workplace culture. Mr. and Dr. Duncan were also kind enough to join D&I Committee members at the Connections Corner for a meet and greet. We had the chance to sit and discuss challenges that each of us face with diversity and inclusion in the water industry. The One Water Conference provided plenty of opportunities to network and connect with other professionals in our industry. This is a crucial aspect of any conference. Members of the D&I Committee were fortunate to meet many attendees at our booth. They were able to share with others what the D&I Committee is about, and invite them to attend a meeting and get involved. RETURN TO TABLE OF CONTENTS

OAWWA’s dedication to diversity and inclusion is commendable. By embracing these values, the conference not only enriches its own content and discussions, but also contributes to a more equitable and innovative water management sector. In a world facing complex water challenges, this commitment to diversity and inclusion is a crucial step toward finding comprehensive and sustainable solutions.

YP MEMBER SPOTLIGHT The spotlight has landed on Katie Fisher, our OAWWA SE District YP Co-Representative, for this newsletter’s YP member feature. Katie, hello and welcome! Can you provide us with some background on where you went to school and how you got started in the industry? I completed both my undergraduate and master’s degrees at Purdue University, where I pursued a Bachelor of Science in Environmental Engineering, and later a Master of Science in the same field. I started my career at a consulting firm based in Indianapolis, where I had the opportunity to work on a variety of wastewater treatment and collection projects, and I passed the Fundamentals of Engineering to become an Engineer-in-Training. Three years ago, I joined MS Consultants, initially in the Pittsburgh office. I have had the privilege to work on challenging and diverse drinking water and wastewater projects. Last fall, I relocated to Columbus and completed the requirements to become a licensed Professional Engineer. You recently attended the One Water Conference. What is your biggest takeaway? My biggest takeaway would be a reinforced appreciation for the pivotal role that water plays in every community. The conference highlighted how essential water is for the sustainable growth and prosperity of our communities. It served as a powerful reminder that water touches every aspect of our lives, from public health and sanitation to economic development and environmental preservation. What is your favorite part of being in the water and wastewater industry? I find it incredibly fulfilling to be involved in projects that address critical issues such as water quality, water supply, and wastewater treatment. Whether it is designing RETURN TO TABLE OF CONTENTS

innovative water treatment systems, improving infrastructure, or optimizing processes, I am constantly motivated by the opportunity to make a positive difference in the world. Additionally, the water/wastewater industry is dynamic and ever evolving, presenting constant challenges and opportunities for innovation. It requires staying up to date with the latest technologies, regulations, and sustainability practices. This continuous learning aspect keeps me engaged and excited about my work, as I am constantly challenged to find optimal solutions to complex problems. What do you like about OAWWA? One of the primary reasons I like OAWWA is the wealth of professional development opportunities it provides. The organization regularly hosts workshops, seminars, and conferences that cover a wide range of topics related to water and wastewater management. These events not only help me stay updated with the latest industry trends but also offer a platform for networking and knowledge sharing with fellow professionals. What are some of your favorite things to do in your free time outside of work and OAWWA? One of my primary passions is powerlifting and general strength training. I love to read and cook. I figure if you can pass college chemistry, you can cook or learn to cook almost anything. Currently, a substantial part of my spare time is dedicated to packing and moving into my first house. Wish me luck that I only break a dish or two. Thank you, Katie, for speaking to us about your experience in the industry and in OAWWA. And most importantly, thank you for your service to the YP committee and water industry! FALL/WINTER 2023

KENT PUBLIC WATER SYSTEM CELEBRATES ITS

100th Anniversary

by John Ellison, Water Plant Manager at Kent Water Treatment Plant

Kent Public Water System

he Kent Public Water System has a long history, dating back to 1880, when Kent’s first water system was completed. This water system was mediocre at best by today’s standards: it consisted of a deep well with a hand pump and a water trough. It was located at the intersection of Main Street and Water Street in downtown Kent. In 1881, Mayor James Woodard hired an engineer to estimate the cost of a new water system. This estimate came to be $53,523. F.M. Loweree, who was representing a group of eastern capitalists, signed a contract with Kent officials in 1886 to build this water system. The water rates were set to be five cents for each 100 gallons delivered to homes, and the installation of 60 fire hydrants priced at 50 dollars each.

The water system was completed on May 13, 1887, and it utilized Plum Creek as its source of drinking water. The original water plant still exists today on the southwest side of Kent, on Mogadore Road. It has since been converted into a daycare. Upon completion of the water system, the contract was transferred to Kent Water Company, owned by the Holly Manufacturing Company in Lockport, New York. In 1889, the Circuit Court ruled the Kent Water Company was permitted to flow 1.35 MGD from Plum Creek. Six shallow wells were drilled west of the water plant that same year. In 1897, six more wells were drilled in anticipation that Plum Creek would likely be deemed an unsafe source of drinking water. The City of Kent was right; the State Health Department ruled in 1898 to disconnect the suction line from Plum Creek.

City of Kent The Kent Water Company was purchased by the Northern Traction and Light Company in 1917, and then on February 27, 1923, the City of Kent purchased the water system. The purchase consisted of the original Water Plant, 101,209 feet of water lines, 113 hydrants, 1,746 in service water meters, numerous valves, and equipment that involved the production and distribution of water for the City of Kent. Bonds were sold to fund the purchase to the tune of $135,000. Mayor Roy Smith and Kent City Council decided to upgrade the water plant in 1930 to produce softened water, a bond issue was set for $35,000 and was passed by council in March. By November of that year, softened water pumped into Kent. By the 1960s, water demand in Kent was a huge concern. The wells at the old water plant could barely keep up with demand. An interconnection with Akron was made, and in 1968, a new well was drilled on the east side of town near Breakneck Creek, the location of the current wellfield. A fire in downtown Kent occurred in 1972, and Kent City Council

was convinced that the City of Kent desperately needed a new source of drinking water, and a new water plant. Four additional wells were drilled, and a new water plant located on Hodgeman Lane was constructed under Mayor Joseph Sorboro. The new Kent Water Treatment Plant began operation on January 13, 1976. This year, On May 9, 2023, the celebration consisted of a history lesson on the Kent public water system from the former Water Plant Manager Steve Hardesty, and a proclamation from Mayor Jerry Fiala of Kent. The celebration also included plant tours by the Water Plant Manager, John Ellison. Ohio EPA gave presentations on source water protection. The Kent Central Maintenance Division explained proper hydrant flushing procedures and watermain repairs, and an explanation on budgeting for the Kent water system came from the Kent Engineering Department.

To the next one hundred years, Kent!

Nanobubble Ozone Technology: A Potential New Treatment for Harmful Algal Blooms BY HALEY KUHN

armful algal blooms (HABs) are a critical water quality issue affecting many waterways in Ohio and in the United States. Cyanobacteria, also known as blue-green algae, are toxin-producing microorganisms that grow rapidly to produce HABs. HABs have recently become more prevalent worldwide because of increasing nutrient levels from anthropogenic practices. HABs can have serious, and sometimes irreversible, effects on wildlife and human health (Figure 1). RETURN TO TABLE OF CONTENTS

In Ohio, microcystins are the most commonly detected cyanotoxin in source and finished drinking water. Currently, copper-based algaecides are one of the most widely used treatment for HABs. However, the use of copper-based algaecides has several downsides, including toxicity to non-target organisms, environmental persistence, and lower effectiveness during cooler months. Thus, we are investigating an alternative method

Figure 1. Advisory sign for harmful algal blooms (HABs) at Grand Lake St. Mary’s, summer 2022.

FALL/WINTER 2023

WATERFRONT

to HAB treatment: nanobubble ozone technology (NBOT) (Figure 2). Ozone (O3) can be used as a powerful treatment method that reacts with HABs through direct oxidation by ozone molecules or through the generation of highly reactive hydroxyl radicals formed during ozone decomposition1. Unlike copper-based algaecides, ozone does not persist in water and decomposes quickly. Nanobubble technology is a newer innovation that has gained popularity in recent years because of potential applications in several industries2. Nanobubbles are microscopic bubbles with diameters typically less than 200 nm (Figure 3). Their small size

provides greater specific surface area compared to normal bubbles and the ability to provide higher mass transfer. Additionally, a lower buoyant force prevents nanobubbles from rising to the surface, increasing retention time in water and contact time with contaminants. By delivering ozone through nanobubbles, the efficacy of ozone treatment may be improved. In this multifaceted project funded by the United States Army Corps of Engineers (USACE), the effectiveness of NBOT for treatment of HABs is being investigated through trials in lakes, streams, and mesocosms as well as bench-scale experiments. The objectives of this project include comparing

NBOT treatment to traditionally used algaecides, investigating the effects on HAB toxin release and degradation, analyzing potential toxicity to non-target organisms, and determining the effects on nutrients and water quality. Field Trial A field trial was conducted at Sunset Beach (also known as Dog Tale Lake) in Grand Lake St. Marys State Park in the summer of 2022 (Figure 4). Grand Lake St. Marys is one of the most HAB impacted lakes in the United States. Sunset Beach is an eight-acre site that is partially disconnected from Grand Lake St. Marys by a rock wall enclosure and a 60-foot curtain at the opening

An oxygen concentrator feeds into an ozone generator(s) which injects ozone into water pumped from the source lake or stream via a venturi system. Ozone treated water flows into a contact tank equipped with an ozone destruct mechanism to eliminate any released gaseous phase ozone. Water is pumped out of the system under constant pressure through a patented nozzle that further creates nanobubbles.

to the rest of the lake. The curtain was installed in an attempt to improve water quality at the beach through various lake management practices. In prior years, aeration, alum treatments, and algaecides were ineffective at reducing the frequency and intensity of HAB events at the beach. During the NBOT trial, four units were installed inside the enclosed location: two on the eastern side of the beach and two on the western side of the beach (Figure 5). To measure water quality, discrete samples were collected at locations inside and outside of the protected beach area, and at the inlet and outlet of the NBOT units. Mesocosm Trial Experiments using controlled outdoor tanks (mesocosms) were conducted at Ohio State University’s Stone Laboratory. The facility consists of 15 tanks with direct water feed from Lake Erie, with each containing approximately 2,000 L of water. The mesocosms were treated as follows: three tanks received no treatment (control tanks), three tanks received copper algaecide, three tanks received peroxide algaecide, 3 tanks received a “low” dose of NBOT treatment (applied dose of 0.9 mg O3/L), and three tanks received a ‘high’ dose of NBOT treatment (applied dose of 4.6 mg O3/L).

Stream Trial In autumn of 2022, an NBOT treatment trial was performed at the Canal Feeder outlet from Grand Lake St. Marys to the St. Marys River (Figure 8). Upstream of the canal, the St. Marys River, is in full attainment of water quality criteria, but downstream of the canal input is considered impaired. Two NBOT units were placed in the Canal Feeder before it overflows into the river, with a treated effluent nozzle placed on each side of the canal to maximize treatment within the canal. Samples were collected from the canal and from the river, both upstream and downstream of the Canal Feeder outlet, to measure the ability of NBOT to treat HABs in flowing water. Bench-Scale Experiments A smaller 2.5 HP NBOT unit provided by Green Water Solutions was used to complete bench scale testing (Figure 9). This unit was modified to have a lower flow rate (~3 gpm) than units deployed in the field (~36 gpm) to allow for more feasible sample collection. The gas generator can be set to produce oxygen gas through the nanobubble pump as well as ozone, allowing for comparison

of the effects of nanobubbles with and without ozone gas. Preliminary Results Results found that NBOT treatment: • Has lower impact on zooplankton compared to other HAB treatments. NBOT-treated mesocosms had the highest number of zooplankton after treatment, nearly double those of the copper and peroxide treated mesocosms. These results indicate that NBOT treatment has lower impact on non-target organisms, a major advantage over algaecides. • Decreased microcystin concentrations. Following treatment, copper treated mesocosms had the highest concentrations of total and aqueous microcystins, while mesocosms treated with the high ozone dose had the lowest total and aqueous microcystin concentrations. The mesocosms treated with peroxide and the mesocosms treated with a low NBOT dose were at the same concentration as the untreated sample. • Decreased chlorophyll-a (chl-a) measurements. Chlorophyll-a measurements are used as a proxy

for concentration of algal biomass. Lower chl-a values indicate reduced levels of cyanobacteria and higher water quality because of treatment. • Decreased Specific Ultraviolet Absorbances (SUVA254) values. SUVA254 measures the aromaticity of organic matter present. Ozone oxidizes organic matter, breaking it down into simpler, less UV-absorbing compounds. Sheering can also cause the physical breakdown of organic matter, decreasing aromaticity. Lower SUVA254 values indicate that treatment of organic matter occurred. Although these preliminary results show potential for NBOT to be used as an effective treatment for HABs, it is unclear how much NBOT treatment is needed to become a viable alternative to copperbased algaecides. Continued research being conducted aims to increase understanding of how NBOT technology works as a HAB treatment, the effects on water quality, and the ozone dose necessary for effective treatment.
