Fall is time to celebrate groundwater

As the temperatures drop (in many places) and we are treated to the changing colors of fall, there are a host of issues that arise with water treatment. Already, many snowbirds are migrating to warmer locations to escape the coming cold season. Of course, we hope they have contacted their expert water treatment specialists to adequately winterize their systems before hitting the road.

A large percentage of the US population enjoys instant access to water drawn from surface sources and subjected to a high level of treatment to ensure its potability. There are, however, many millions who rely on private wells that tap into groundwater sources. As many of these are privately owned, they are not (as yet) required to maintain the stringent controls and testing that are in place in public water treatment systems. More and more, we hear about private well contamination and how it can be prevented. But there are a number of reasons why that doesn’t happen.

Kevin McCray, CAE presents a very comprehensive update on the groundwater industry, including information about proper well water treatment. Cost and consumer misunderstanding are primary barriers to private well testing. This article is a well-rounded treatise explaining the reasons we need to be better stewards of our precious water resources.

Peter Cartwright, PE, continues his series on drinking water contaminants with a broad list of treatment technologies available to combat PPCP contamination. We all use soap, shampoo, prescription drugs and other items that eventually find their way into our water sources. Few of them are benign and the proper treatment must be applied to make water safe to use. With potable reuse gaining traction as a way to offset water scarcity, it’s imperative we find a way to effectively deal with the contamination these everyday products are contributing to our water systems.

Each October, the Pacific Water Quality Association holds its annual convention and exposition. One of the longest-lived regional associations, there is always a good crowd with lots of exceptional educational opportunities and certification testing. This year was no exception as the organization headed south to San Diego, CA to celebrate its 60th year of bringing water quality experts, manufacturers, dealers and representatives together. They say a picture is worth a thousand words…that being true, in this issue we offer many for you to enjoy. In addition this month, Public Health Editor Kelly Reynolds, MSPH, PhD, takes a closer look at Leptosporosis infections that are the result of waterborne contamination.

We still have a few conventions of note before the end of the year. Both Aquatech Amsterdam and the National Groundwater Association (NGWA) annual convention, Groundwater Week, are especially useful to water treatment industry partners. We hope to see you in Amsterdam this month. Or maybe you’ll be making the rounds at Groundwater Week in Nashville, TN, in early December. Make sure you take advantage of any opportunity that will give you the business edge and educational requirements needed to be standout performers in your area.

We hope you have a wonderful Thanksgiving and enjoy the fruits of your labors over the past months. With colder weather setting it, a crackling fire seems the perfect companion to family and good food.

 All the world’s a water stage

There are two things humans cannot live without: air and water. While in the developed world we know them to be seemingly plentiful, in nearly every region both are polluted to some degree. Industrialized nations have learned (for the most part) to put processes into place to prevent the ubiquitous pollution but even they must contend with the constant threat of emerging contaminants. It’s in this framework of cause and effect that the water treatment industry must operate to find the best and safest solutions to water quality issues. But it isn’t an easy task.

In addition to known threats to water safety, there are a host of issues that are creeping to the forefront of industry consciousness, namely a multitude of unregulated contaminants, the push to go green and the need for sustainability. Some of the goals are bound to come into conflict because there are so many approaches for overcoming the problems. Long the backbone of water treatment, chemistry is now being looked at more closely as it relates to the use of plastic, nano materials and other latest-and-greatest products that are creating both intended and unintended consequences.

Peter Cartwright, PE, provides a fascinating two-part article on the contaminant of the month and those yet to emerge as well as what can be done to mitigate the problems that arise. The first part goes in depth to define what is known about water and chemistry and what is only now beginning to come to light. Why was something vaunted as the next big thing in plastics now touted as an environmental crisis? There is no easy answer, though Cartwright leads us through what works in water treatment, as well as the disadvantages that are now being seen.

No system has yet been created and produced that does not need some measure of maintenance. One of the biggest culprits in water treatment is keeping all the parts in working order to ensure a level of consistently high cleanliness. This is a difficult premise when biofilm is part of the problem. Greg Reyneke of Red Fox Advisors presents the whys and wherefores of system sanitization for both timed maintenance intervals as well as yearly schedules. It cannot be stressed enough that no system is maintenance-free!

Dr. Kelly Reynolds, Public Health Editor, reviews the growing acceptance of potable reuse water on a global scale. The many methods for reuse may help offset the problems associated with water scarcity that now threaten the entire world. It’s not a developing nations issue any longer.

As we approach the end of the calendar year, convention season is still going strong. We hope to see you often, at upcoming conventions and trade shows and if not, drop us a line and let us know how we’re doing. If you want something covered, tell us what is missing from our coverage and we’ll try to be as inclusive as possible. On a side note, we’ve changed the groundwater/arsenic topics to the November issue and moved desalination/wastewater to December. If you have an unpublished white paper or want to write on those topics, by all means, get in touch. We’re always looking for talented industry experts to help us inform our readers!

Taking it with you?

One of the most logical answers to the maxim that water is life is immediate access anywhere and everywhere. For generations, getting a drink from an inside or outside source meant finding a faucet or water bib or a garden hose. As our society has become more mobile and on the go, water coolers (that you probably remember from every public building and school you attended) provided this much needed beverage. But for many years, water had to compete directly with the sugar-toothed monster of modern society: carbonated sodas. Until just recently, water was the also-ran in a world of convenience and necessity.
Today, when you visit a business office, you may well see a water cooler with a three- or five-gallon bottle providing a fresh drink. Or maybe there’s a cooler with multiple options, such as hot and ambient water. Or you might find an entire beverage dispensing system, that includes not only water but also coffee, hot chocolate and other goodies. Each of these systems are advancements in technology and those advancements require the technical expertise to install and maintain each type.
Wesley Bleed, Communications Director of WQA, reports on a new training and certification program that is specific to the water-cooler industry. It’s not as simple as popping a new bottle of water atop a cooler unit anymore. There are many considerations, including service, maintenance, disinfection and more. Now is the time for those involved in the water-cooler markets to take heed of the opportunity to have installers and technicians go to the next level with industry-accepted certification.
The most notable of water sources for most is the 20-ounce plastic bottle. And all that bottled water has its own regulatory requirements, manufacturing and production models, etc. Jill Culora, VP of Communications for the International Bottled Water Association, provides an in-depth update of all things related to bottled water. The organization is cheering the recent move to first place and with good reason. It’s a beverage choice that could have long-term benefits for our society as it moves toward a more healthy lifestyle.
In other coverage this month, Tom Palkon and Tina Donda review the upcoming 2021 Uniform Plumbing Code, as it relates to the water treatment industry. Xylem’s Sukri Elmazi presents steps to minimize lead contamination in residential settings. Tim Keister provides insight on the benefits of using softened water in cooling towers and Chris Knippa opines on why emarketing is still a viable option. Dr. Kelly Reynolds examines an issue of adverse effects on human reproduction due to waterborne contaminants. This phenomenon has been noted in a number of research papers, including those relating to the use of BPA in plastic bottles. It’s important to note that the current substitute, BPS, is also getting a much closer look for many of the same issues that may have arisen with BPA use.
There’s a lot to consider in this month’s coverage and more is coming your way in future issues, as we seek to keep you well-informed and engaged in our industry. There is no more highly-regulated industry than water treatment and staying at the top of your game requires a great deal of time, effort and energy. That pays dividends that may not be readily recognizable but fostering the trust and good health of humanity is always an honorable and worthwhile pursuit.

 Hot enough for you?

Our summer heat has been grueling and it’s not over yet. Many parts of the West, while somewhat recovered from a years-long drought thanks to record winter precipitation, are being consumed by wildfires. In other words, rather than the standard list of contaminants water treatment specialists normally deal with on a regular basis, add fire retardant and ash to the mix. The magical boundaries between states (even counties) on that wall map don’t mean anything to Mother Nature. Particulates are known to travel vast distances on wind currents. Are you ready for them?

We often use the terms sanitizing and disinfecting in the same way, though they are different. The technologies needed to accomplish either also differ. Ozone is beginning to gain traction in new markets because of its remarkable ability to inactivate microorganisms, thereby prompting the assessment of disinfection to be used. The same goes for sanitization. Ozone does a great job, but there are limits. Darrell Weeter of Oxidize It Pro writes this month about the benefits and some of the limitations in the use of ozone. In addition, Greg Reyneke of Red Fox Advisors delves into using ozonation for pool and spa water treatment. Remember, particulates do fall from the sky, impacting water features, pools and spas. Water treatment options already in place may need some adjusting if they are impacted by additional organic loading.

Gary Battenberg, Parker Hannifin, concludes his two-part series on connectors and tubing with two case studies that illustrate the necessity of sourcing the right materials for the job. Do it right the first time to avoid these situations. Tom Spoden of the Water Quality Association revisits re-certification protocols in this issue. Yes, it is necessary to re-certify products and he details when and why. ‘Data Dale’ Filhaber provides us with insight on marketing to the Millennial generation. They do think differently from past generations and getting them on board with water treatment presents new challenges, as she outlines in her article. And Public Health Editor Dr. Kelly Reynolds wraps up this month’s coverage by addressing the problem of DBPs in pool treatment and what needs to be done to overcome this pressing issue.

As the dog days of summer descend upon the nation, we might ask what is different this year about how we do business and what has changed, in order to plan accordingly for our future endeavors. The planet itself may have been responsible for some of those changes while the economic and political landscapes have surely changed some perceptions as well. In order to be successful, you need to know not only your audience but your business and its limitations. That might be the next thing to change, through training, outreach and expansion. Only you will know for sure what is right for your business model. We hope to see you at upcoming events. EWQA and PWQA annual conventions are right around the corner, as is WQA Mid-year. Get your registrations in right away!

 Time to treat and reuse water

It’s heating up quickly in several parts of the country, although recent heavy storms in the Sierra Nevada and Florida appear to have broken the backs of their respective droughts, at least for now. The dire consequences of drought in the food belt of California brought into question the wisdom of letting rainwater go to waste, leaving desal plants decommissioned and other possible drought-mitigation strategies to languish. All around the country, however, people and local governments are beginning to realize the methods of previous generations are again ready for prime time. But leaving out pans and pails to collect rainwater is no longer feasible because there are more pollutants in the air and water; rainwater running off rooftops is most likely contaminated with asphalt from shingles as well as organic matter. Because of these contaminants, rainwater can no longer be used from cloud to tap.

Peter Cartwright, PE, gives us an overview of rainwater harvesting and reuse systems, with a follow-up article expected soon on treatment options. He details the design of both residential and commercial reuse systems that are sure to catch the eye of those wishing to build redundancy into water sourcing. Rooftop catchment systems are already in place in several cities across the nation and more will probably be coming to a city near you. Be on the forefront of this to take an active part in design and treatment.

The go-to treatment option for most applications is reverse osmosis. A work-horse treatment for more than 50 years, the purity of water is essential in some applications, greatly desired in others. It’s removal capacity is dependent upon a well-designed system and there are standards to be met. Rick Andrew of NSF, International takes us through those requirements in his Water Matters column. It’s simply not as simple as it might look. In addition, Parker Hannifin’s Gary Battenberg reviews an often-overlooked issue with RO systems: tubing and connections. If they aren’t right, systems won’t work properly.

We know there are changes in thought processes among generations that can create misunderstandings, mostly resulting from unmet expectations. Millennials are thought to be disconnected in some ways, needing special handling to engage them in both life and employment environs, but no generation is without its expectations. We are reprinting an excellent article by John Blount of Pure & Gentle Soap about bringing Millennials to tap water. It’s an interesting perspective in how to get them to focus on the resources they have readily available. Public Health Editor Dr. Kelly A. Reynolds reports on the Centers for Medicare and Medicaid Services directive that healthcare facilities must reduce legionellosis risks from tap water. This ongoing problem is getting worse and must be addressed now.

This is the busy season, for everyone. Conferences around the world demand attention and attendance, whenever possible. It benefits those who attend by raising their levels of awareness about new products and technologies, as well as being central hubs of educational opportunities. Try to make it to WQA’s annual convention, of course, but also give the regional WQA events consideration. You’ll gain the advantage of expertise offered freely by industry experts to enhance your own toolkit.

Welcome to 2011!

We’re hopeful everyone is starting the New Year on a more positive note than last year. Recent reports in the media cite modest gains in certain industries while others are maintaining but not progressing. With our industry so closely tied to the housing sector, the news hasn’t been particularly good for quite awhile. Should we expect that negative trend to last? Possibly, but not in the same way you might expect. Every economist worth their salt has chimed in on what when wrong and how, what needs to be done to correct the severe imbalances in the economy and how to get the world moving forward again. There are as many opinions as there are reasons. Things are moving again, though much more slowly than what was expected. If Americans are expecting double-digit rises in the economy to occur, they will be disappointed. That doesn’t mean it won’t turn around; it just means it will take longer.

With the change in calendar numbers comes the possibility of other changes as well. Technology has rapidly outpaced the typical mindset as it races to new levels, and while most humans grapple with each new discovery with a sense of awe, businesses must take a different approach. Keeping up means staying in business; adapting means staying competitive in the race for market share.

For any number of businesses, this does not mean their efforts to ride out the storm have failed. It means they have to keep trying harder and for a longer period of time to move forward. If ever there was a reason to re-examine policies, training goals and marketing messages, the last two years have provided the incentive. Tried-and-true methods may need re-examination to meet the demands of a decidedly changed business landscape. In this vein, David Martin’s Creative Marketing column covers the basics of expanding existing efforts to find new customers while Gary Coon focuses on how to make good sales people better. Technical Reviewer Andrew Warnes offers yet another of his insightful predictions on where the water treatment industry is heading in 2011 and beyond. Yes, it is getting better, incrementally.

The industry has grappled with the relationship between softeners and physical water treatment devices for years without much success in finding a plane of peaceful coexistence. The Arizona Water Quality Association recently hosted Dr. Peter Fox of Arizona State University to present findings on a study funded by the WateReuse Foundation on the possibilities of non-chemical (or saltless) treatment. Many municipalities have expressed an interest in the study, in part to be better positioned to act if more stringent legislation arises. In the chemical versus non-chemical war, presenting both treatment types and their benefits correctly is of the utmost importance. Technical Reviewer C. F. ‘Chubb’ Michaud explores this in his article.

Overall, the expectations of the industry can be met if there is a collective effort on the part of dealers, distributors and manufacturers to place more emphasis on the benefits of their respective products and technologies using the Battelle Study as a selling point. Consumers are not returning to the days of buying for the sake of buying; they are more tech-savvy and overall value is of far greater importance to them. With this in mind, it’s up to the industry to turn things around by presenting options that provide the best bang for the buck to both new and existing customers. Are you up to the challenge of the new decade and this new reality?

 Get ready for hot temperatures and water issues

As temperatures rise across the country, it’s time for water treatment dealers to deal with more service calls for biological contaminant issues. Microbes are the one group of living creatures that are known to inhabit extremes and heat is their friend, not yours. As with algal blooms in regional water bodies, biofilms may also develop in water treatment systems, cisterns, cooling towers and more. It’s imperative that the water treatment includes a multi-barrier approach to ensure safe, clean water to those most dependent upon these sources.
Treatment trains often include the mainstay of water treatment: activated carbon. Whether it’s the sole option or part of a more complex system, the benefits of carbon are unmistakable. To address our main topic, we have a general review of activated carbon filters by Dr. Henry Nowicki and the staff of PACS, Inc. Following up on last month’s pictorial coverage of WQA’s Annual Conference and Exhibition in Orlando, FL, we take a closer look at the highlights, awards and perceptions of visitors and vendors alike. On the trade show floor, the number of products is amazing and the ‘marks’ of third-party testing agencies are in full view. When and how often are they tested? IAPMO Group’s Tom Palkon offers insight into the certification and listing process, while trying to answer that question within the limitations of certification itself.
Disinfection of water systems, pools and water coolers is easily accomplished with UV, a treatment option that is in wide use (primarily) in the commercial and municipal markets. VIQUA’s Diane Arnott and Anthony Ooserveld take a closer look at how UV is becoming more useful in the residential arena as well. Everyone has a nightmare story about customer issues and some border on the hilarious. To highlight the latter, David and Joshua Davies of Aqua General, Inc. gives us a few examples of how to handle the odd, the strange and the weird.
Public Health Editor Dr. Kelly A. Reynolds discusses the groundwater risk factors that arise with the onset of summer rains. This is another area of contamination that gets little notice but creates drinking water risk. There is no simplistic approach to water treatment, although some methodologies may be the simplest approach to resolving issues. In the age of emerging contaminants, though, the level of complexity must outpace the the regulatory requirements.
To reassure consumers that water treatment dealers are their go-to candidates, they must take time to expand their knowledge base and gain experience in an ever-widening field of problems, in order to be the resident expert who takes their clients’ concerns seriously. The more you know, the better you perform and the safer the water will be for everyone. Our coverage is meant to broaden your horizons, so to speak, by offering the insights and expertise of water industry experts. If there’s a topic we haven’t covered but should, let us know and we’ll find the experts to educate and guide you.

Longer days to ponder

With the onset of spring, a great many graduations will take place, sending a multitude of young people forward into careers or secondary education. For employers, the opportunity to pick the best and the brightest should not be missed! Many of those entering the work force with advanced degrees may well turn out to be the next generation of innovators in the water treatment industry. From the Stockholm Junior Prize Winner to AWWA’s Young Professionals to the curious kids doing experiments in their parents’ garages (or kitchens), there is a multitude of future geniuses who can make the impossible happen, with the right mentoring and guidance. The path to innovation is a collaborative journey full of youthful curiosity and mature intelligence.

May is UV month, a technology used primarily in larger, commercial and industrial applications. But that appears to be changing. As with filtration and other widely accepted water treatment strategies, adding UV to a treatment train is becoming more common, even in residential applications. Water cooler manufacturers also have been incorporating UV disinfection into their systems. Consumers realize the viability of UV to help keep their drinking water cleaner and will ultimately drive the market. And, as filtration is not just filtration anymore, UV is not just a one-trick pony either. A trio of authors from Trojan Technologies presents an overview of UVC-LED technology that focuses on the advancement of this disinfection method. Nothing is static in water treatment and that holds true for UV as well.

Technology advances by collaboration and one of the largest collaborations in the world is The Water Council, a fascinating conglomerate of academics, scientists and forward-thinking innovators, all in one building. David Swiderski of Aquor explains the mission of Milwaukee, Wisconsin’s biggest contribution to achieving clean, safe water now and in the future. WQA’s annual convention, held in Orlando, Florida this year, was better than ever. From educational sessions to booth presentations, nothing was left out. To mark the occasion, we will have a two-part feature on everything WQA, beginning with a collage of images that captures the energy and upbeat atmosphere of the event. Also in this issue, C.F. ‘Chubb’ Michaud presents his final chapter on ion exchange, examining the aging factor involved in cross-linked resins. Dr. Kelly Reynolds gives a nod to technology in her report on how people searching for information on waterborne illness can be a tool to track outbreaks and other water-associated events.

Something for everyone is commonly mentioned about WQA conventions and we hope you’re saying the same thing about WC&P International. We strive to meet your information needs through the magazine, website and twice-monthly POU-POeNews. If there’s something you think needs more coverage, let us know and we’ll take a closer look. We’re here for you and this is just another collaborative effort to make our water safer for everyone.

Did spring come early this year?

You might not think that spring arrived early, based on the unusual weather that’s been occurring across the country. For California, though, the combination of record rainfall and record snowfall in the Sierra Nevada mountains may continue to be cause for concern. Flooding in areas not touched by such a phenomenon has been consistent in the news reports over the past several weeks. And with warmer weather, melting snow packs may bring yet more damaging floods. The need for clean water resources can quickly outpace a region’s efforts to ensure the availability of potable water, a common enough theme in the Southwest as well. Mother Nature can and does throw an element of uncertainty into the best laid plans.

So what does this mean to water treatment specialists? Plenty! If you have routine maintenance scheduled for the change of seasons, you already know that weather can dictate a host of water issues, from bacterial growth due to warmer temperatures to broken piping from the cold. But how many are ready to handle flood-water intrusion to both small public and private well systems? Or sewage overflows that may impact the immediate groundwater resources? Floods bring silt, turbidity and organics front and center in the treatment scheme when unusual weather rears its ugly head. The need for bottled water increases exponentially during these events as well.

Since the Great Recession, many dealers have found themselves more involved in larger treatment applications, such as small businesses like restaurants, car washes and maybe a local hotel or motel. These can be much different than residential applications, although the same technologies may be used. In this issue, C.F. ‘Chubb’ Michaud addresses the chemistry of reactions found with ion exchange resins, which are used broadly in both residential and commercial water treatment. Greater attention must be paid to determining the right chemistry for the right application. In his usual in-depth fashion, Michaud explores the various types of reactions and how they relate to the ion exchange process and what is necessary to meet the needs of the client.

Who doesn’t have service vehicles? Are you doing all you can to save money on purchases, insurance and maintenance? What about safe driving? Rich Radi of ARI Fleet Management Systems offers insights on how to better track the performance of your vehicles and how safe driving can save a lot on overhead expenditures. It’s good business practice to make sure the vehicle with your company name on the side isn’t remembered for bad driving!

Dr. Kelly A. Reynolds, Public Health Editor, takes a closer look at PFOA and PFOS health effects, following up on a previous NSF International article on certification requirements to prevent these contaminants. While current information may indicate advisory alerts may be in order, there is still room for much caution on the part of water treatment specialists.

Conference season is in full swing and ever more activities are available to help you become better at what you do. Training, conventions, exhibitions…there is something for everyone at every level of water treatment. If you went to WQA’s Annual Convention & Exposition, you should have come home with lots of good ideas, additional training and a wealth of networking experience. There are more conferences on the horizon, some with a very specific water treatment focus and others that cover anything related to water itself. Be sure to take advantage of these whenever possible. The more you learn, the more you know, and that puts you a few steps ahead of your competitors.

Guest Viewpoint: WQA Executive Director Pauli Undesser

Wednesday, February 15th, 2017

By Pauli Undesser, MWS, WQA Executive Director

feb2017_undesser_mug_2017_colorThis is the year of impact for the Water Quality Association. With the crisis in Flint, MI still fresh in the minds of consumers and regulators, our members will be called upon to help educate and protect the public, perhaps in new and innovative ways. It is, without a doubt, a pivotal time in the water treatment industry. With our 2017 consumer opinion study being conducted this year, WQA and its members will be able to gain new insights into consumers’ perceptions about the quality of their drinking water and what types of treatment they might consider for their homes or workplaces.
The Flint crisis has permanently changed consumer perceptions about drinking water. But it was just one of many water-related stories making news across the nation in the past couple of years. Toledo had a crisis involving microcystin contamination in its municipal water system; 10 thousand gallons of crude 4-Methylcyclohexanemethanol (MCHM) spilled into the Elk River in West Virginia. So, it’s not just Flint and it’s not just lead. We see a variety of threats and concerns across the nation.
In the wake of the Flint crisis, WQA updated its crisis plan to offer a quicker response and resources when warranted. Once an event is considered a crisis, the plan calls for WQA to:
•    Send out emails to its members with updates on the crisis
•    Reach out to the appropriate state association, if available, to lend support
•    Distribute news releases announcing WQA’s position on the crisis and make appropriate resources available
•    Create informational handouts for members
•    Reach out to local and state authorities, offering WQA as an educational resource and pointing to certified products and professionals
One of my goals as the new Executive Director is for WQA to more firmly establish itself as a valuable source of information and knowledge. WQA’s Government and Regulatory Affairs will remain active in building recognition for WQA and its members on Capitol Hill, within federal agencies and in key state legislatures. WQA formed a federal political action committee this year to increase the association’s participation in the political process and further foster relations with legislators to ensure our needs are heard.
WQA continues to position itself as the leading advocate in the drinking water industry when it comes to professional and product certification. This year, our Professional Certification Department will continue to revise its exams to reflect an emphasis on field-work experience. It will also continue to develop the POU cooler-specific installer training module. Meanwhile, Product Certification will continue to develop and offer new certification services in 2017 to meet domestic and global market needs, such as NSF/ANSI 401 for pharmaceutical reduction.
So, the spotlight on our association and our industry is shining brighter these days. We’re rising to meet the new challenges. It’s our hope and mission to continue to do all we can to educate and inform the public, while equipping our members to be the very best in promoting the betterment of clean drinking water.
