Venting Ventilation

2011-05-06T18:21:00.006-04:00

Today I received an email through the Texas Public Pool Council Group requesting assistance with ventilation issues from an associated network member in Kansas. This concern repeats itself over and over again in the print and electronic media, social networks and blogs. The ventilation issue is so prevalent that the CDC has assigned the issue to one of it's dedicated Model Aquatic Health Code development committees, the Ventilation & Air Quality Committee. They have recently posted their module abstract for public comment, which can be accessed at http://www.cdc.gov/healthywater/swimming/pools/mahc/structure-content/. In sorting out this whole air quality issue in my mind I can't help but think that somewhere along the way we have missed the source of the concern, the water. In light of that, I thought I would post the content of my reply email, which brings the issue back around to basic chlorination. What do you think?

This is my reply:

Here is another article that addresses your concern written by Richard Young and published in the Pumproom Press, a periodical of the Professional Pool Operators of America.

Tired of Chloramine Odor?

Read down to "So what can be done?" and please take note of the solution to poor air and water quality offered - PREVENTION. That paragraph ends with, "Most pools can preclude the formation of chloramine residuals through diligent chlorination with wisely-chosen, constantly maintained break point." I know that this sounds easier than it generally proves out in practice, but it can be readily accomplished. The key to prevention and critical component that is usually missing when attempting to hold "continuous breakpoint" as defined in the AFO Manual (not the 10 x combined chlorine treatment that is known as "breakpoint chlorination") is "properly sized feeders". As stated by Kent Williams in his article, Controller Concepts: The #1 Rule (sited below), "chemical feed systems must be big, big, big!". Feeders that are sized to meet a pools' gpd requirement cannot meet the minute to minute demand of heavily used indoor pools. Feed systems must be over sized to enable your controller to hold an ORP set point that will continuously exceed demand. Chloramine development can be effectively prevented in most cases without remedial treatments or secondary systems designed for that purpose when this is accomplished.

Two helpful supportive articles can be found at www.ppoa.org; (1) http://bit.ly/9nhWz6ppoa and (2) http://bit.ly/bRCc3uppoa. Both of these were posted in my comment to the 2nd Athletic Business article you sited in your email inquiry. (Article sited: http://athleticbusiness.com/articles/article.aspx?articleid=3598&zoneid=20)

As an Aquatics Manager and Pool Operator for over 20 years, I have a sincere concern for those working every day to provide a safe and healthy environment for their guests. I would be glad to support you in this effort. Please let me know what you think!

SureWater's Profiles in Purity

2010-08-17T23:55:00.019-04:00

As an experienced pool operator, you can pretty much tell if your water is right just by looking at it. The appearance of the water alone says a lot about it's level of purity, chemistry not withstanding. Recreational water that is balanced, contained within a well kept vessel, and is holding an ORP consistently ahead of the organic load has a certain look. Words can describe it, but a picture does it better.

In future months we will be profiling our customer's "pristine waters". Here's the first of many "Profiles in Purity": Geauga Lake's Wildwater Kingdom

AOL Undercover: You Got Inspected!

2010-08-10T07:10:00.009-04:00

Here's a recurring sign of the times and likely a scenario that will continue into the future. AOL Travel reporters recently made unannounced visits to five popular water parks across the US to check for the presence of bacteria in their swimming pools during regular park hours. The results were both a direct reflection on the operators within each of the parks and the water quality standards by which they maintain their facilities, and the industry as a whole.

More later on advocacy for the swimmers' health with some thoughts on how operators might get a leg up on this developing standard of care. In the mean time, check out What's Living in Your Water Park? and don't forget to take the reader's poll at the bottom.

Congrats to SureWater customers Raging Waters San Dimas and Wet 'N Wild Orlando as well as all of the parks and operators involved in this study. You make us all proud!

A Chloramine Prevention Precursor: Are You "Practicing" Healthy Swimming at Your Pool?

2010-02-11T07:00:00.001-05:00

I am a believer in the benefits of social media and find it in its' various forms to be an increasingly invaluable tool to me in business. I have maintained a company page that many of you are aware of at twitter.com/sureh2o for some time now. Through that site I follow a number of other sites ("Tweeps"), some news related, some business and of course some related to swimming. It has been interesting to follow some well known swimmers like @daratorresswims, @NatalieCoughlin, @G_WeberGale, and @goldmedalmel (Mel Stewart), all of whom are past or current US Olympic Swim Team members and gold medal winners. Recently, I spotted a post on Mel Stewart's Twitter page (twitter.com/goldmedalmel) linked to a post on his blog entitled Chlorine and Pee Can Kill You, which got my attention. After reading his post and the referenced article, KEY Health Facts You Need to Know if You Have or Use a Pool, and a follow up post that provides the unique perspective of a competitive swimmers' urination on the "fly" experiences, Peeing in the Pool (with Video), I felt compelled to post a comment in reply.

I have commented on many articles in the past, but none with the response that my comments received from Mel Stewart. He received them with open arms, posting them verbatim in a follow up post on his blog (see my comments @ Chlorine and Urine can Kill, Part II). Mel didn't stop there. In the interest of his readers' personal knowledge and health, he invited me to write up a list of steps that can be employed at their facilities to help prevent the formation of chloramines to be included on his blog as a "guest post". The link for this post, what I called a "Chloramine Prevention Precursor", was posted on his blog in full at Chlorine and Human Secretions, THE FACTS. Take a quick look! You are probably already incorporating many, if not all of these steps into your operation, but how far are we going as Operators to cooperatively establish workable prevention protocol with the competitive groups that are using our facilities. Here's where relationship plays a vital role in assuring the "best practices" are not just in place, but are being PRACTICED. On behalf of Mel Stewart, I would encourage you to share his posts with your swim, water polo, synchro and other team coaches and parents in a cooperative effort to provide the healthiest environment possible for the participants and staff of your facility.

I want to publicly thank Mel for his commitment to swimmers and to healthful swimming by shedding light on the issue of chloramines and for presenting the opportunity for me to link the Pool Operator community with the Competitive Swimming world in an effort to inform and ensure the "practice" of healthy swimming in all of our facilities. Be Sure!

Solutions "On-Line"New York Sports Clubs

2010-01-26T08:45:00.009-05:00

The following post was recently provided by Clemente Rivera, a long-term user of SureWater Technologies products, who is currently serving as a Regional Pool Manager with New York Sports Clubs. Clemente has integrated "The Solution X-2" into several of the facilities he is responsible for with great success in the area of water chemistry management and specifically with the control of combined chlorine. Should you want to discuss his results with him further, please email me at robert@sureh2o.com and I will forward his contact info to you. I'll step out of the way now and let him describe his experience.

[Clemente] I just wanted to say that I’m very happy with the progress of the X-2 Installations in the New York Sports Clubs. We have a Dual System in Butler, NJ (pictured), a system running a Pool and Spa in Ramsey, NJ, and a X-2 Chlorinator install in Deer Park, NY.

The Systems are running very well. I have gotten very positive feedback from staff, and members alike. Most members think we don’t use chlorine! “We cant smell it”, is their surprising response…”you must be using Salt…”, when I tell them that is not the case, they still look dumbfounded. I love it!

After about a month tweaking them all, I found one trend that is very exciting…There is in fact a “sweet spot” in dosing, that you can set any pool to obtain the appropriate amount of sanitation to offset organic demand, AND chloramine buildup. After dealing with 3 pools of approximately the same size, with varying degrees of usage, I have found that a feed setting of no more than 11ppm per hour is needed to achieve the proper sanitation levels in your pool – in conjunction with a maintained chlorine level of about 2.5-3.0 ppm. At this level, My logs have been flawless in showing Combined Chlorine readings of no more than 0.2 ppm!!! Before that, I had to maintain these pools at 4ppm, and they still yielded chloramine levels of 1.0ppm and above…

How to achieve these results:
For the X-2 Feeder:
1. Calculate Pool Volume: L x W x Avg Depth X 7.5 = Pool gallons
2. Divide that volume by 10,000, then multiply it by 117.7
3. Take that number and divide by 128. This is your GALLONS per HOUR. Set your X-2 feeder accordingly.

For The Solution – since it reads chlorine flow in gpm – divide the above result by 60, for your Solution setting.

This setting will provide the sanitation level you need to feed Bleach into your pool.

Now – slowly set your ORP upwards, until you are maintaining 2.5-3.0 ppm, with a pH of 7.4, and you're set! (PPM controllers: simply set your PPM to the same range). Do this with a pool with high chloramines, and let me know how fast the chloramines drop…My record is 2 weeks (the pool had 2.0ppm chloramines in it before I started, and it went down to 0.2 ppm - without shocking!) – within the month – the room actually smells like the rest of the club!

After the first 2 weeks, recheck your ORP settings…you may find that the Initial ORP setting now makes for too low of a chlorine reading; this is due to the organic loads being overcome by the chlorine, resulting in less chlorine needed to achieve the ORP setting. Bring up your setting to the appropriate setting to maintain the 2.5 – 3.0 chlorine level, and you guarantee the most sterile water possible. Your sensors will not need acid cleanings, as the organics will be negligible at this point, and you will enjoy the sweet smell of ultra low chloramines; without the use of UV, using BLEACH!

If any of your constituents need any advice, or want to show me what they have done, please feel free to pass my info to them. I'm working on a useful calculation for X-2 pH feed shortly.

Cudos to the Avant-Garde

2009-12-02T16:13:00.010-05:00

Is there a particular reason that we keep seeing our users in the news for top performance recognition? Is it just chance that these facilities keep scoring accolades for their organizations. I'm not suggesting that it is because they are using SureWater products that they are garnering recognition, but there is an interesting correlation. SureWater users tend to operate within the realm of the avant-garde. Innovation is the hallmark of these people who search for the "best" answer to an issue, not just any answer. People who are motivated to go above and beyond in seeking solutions for the future, not just to get through to tomorrow. Courageous people, who strive to open pathways through political and industrial bureaucratic terrain for their peers to follow.

Wikipedia took this definition of avant-garde from encyclopedia.com and I love how it frames the innovators in our industry. The term, "avant-garde", was originally used to describe the foremost part of an army advancing into battle (also called the vanguard) and now applies to any group that considers itself innovative and ahead of the majority. It goes on, the vanguard, a small troop of highly skilled soldiers, explores the terrain ahead of a large advancing army and plots a course for the army to follow. Great word picture! This is exactly what the avant-garde in the recreational water industry are doing every day in their respective work places and industry networks. They apply this attitude to every aspect of their jobs. This is why you will not only find them employing cutting edge technologies in their pump rooms, but you will also find innovation uniquely present in every element of their operation. Does everyone who operates in the realm of the avant-garde receive recognition for this attribute? Not hardly! But recognition is superfluous to the avant-garde. Above all is service. Service to their industry, service to their employer, and service to themselves. Nothing more, nothing less will do.

I see it as part of my job to high light some of the successes of our users that might otherwise and unfortunately go unnoticed. Congratulations to the Fox Valley Park District in Aurora, IL for receiving theGold Medal Award (Class II) for Excellence in Park and Recreation Management presented by the American Academy for Park and Recreation Administration at the recent NRPA Congress in Salt Lake City, UT. Special cudos goes out to the Fox Valley Aquatics Staff for their leadership and dedication to innovation in the field of Aquatic Facility Management. A long term user of SureWater Technologies feed systems, Fox Valley very successfully utilizes both "The Solution" for disinfection purposes and "The Solution X-2" for pH control in all of their indoor and outdoor swimming pools.

Fox Valley's Splash Country Waterpark

Congratulations are also in order for the Chaos Waterpark Resort in Eau Claire, WI for being selected by Aquatics International Magazine as the Best Waterpark Resort in their 2009 Best of Aquatics Competition. Chaos Waterpark, an exiting new themed attraction of the Metropolis Resort, employs SureWater High Capacity Feed Systems as an integral component of their innovative "green-friendly" strategy to facility management and resource conservation. Special thanks and congrats to Barry Thompson of the Metropolis Resort and Al Neumann of AJ Contract Services in Wausau for their avant-garde approach to water quality and facility management!

Oh No, Crypto!

2009-03-17T08:38:00.047-04:00

"With a Purposeful Grimace and a Terrible Sound
He Pulls the Spitting High Tension Wires Down

Helpless People On a Subway Train
Scream Bug-eyed As He Looks in On Them

He Picks Up a House and He Throws It Back Down
As He Wades Through the Buildings Toward the Center of Town

Oh No, They Say He's Got to Go, Go Go Godzilla
Oh No, There Goes Tokyo, Go Go Go Crypto"

The whimsical lyrics to Blue Oyster Cult's "Godzilla" spring immediately to mind as I read on and on about the dreaded Cryptosporidium! These lyrics take on a somewhat profound yet intentionally humorous meaning as the words "Go Crypto" are substituted for "Godzilla".

Regrettably, crypto is no laughing matter. In fact, it is a very real and menacing "intruder" when it finds it's way into our drinking or recreational waters. It wreaks havoc on an unsuspecting intestinal system in much the same way Godzilla did (on film) in the streets of Tokyo. And like Godzilla, crypto is tough to kill. As a result, practitioners within our industry have found themselves in a precarious situation, grasping for an effective weapon to eliminate this foe. The notorious "creature" is loose in the "streets" of our swimming pools and as the minister of defense we've got to decide if, and/or when to call out the heavy artillery.

Just when it seemed that Godzilla would bring utter and complete devastation, the inhabitants of Tokyo would turn up the defensive heat, driving him back into the sea from which he came. We can, and must do the same thing with Crypto. That is, turn up the "heat"! In our case, the "heat" is ORP. Yes, Oxidation Reduction Potential, or qualitative kill power. True heavy artillery in the on-going pathogen battle!

Crypto is a formidable opponent, but it is not the nearly indestructible "monster" it is portrayed as by some. There is well documented scholarly research giving evidence to the fact that it is readily and fully deactivated in as little as 30 to 120 minutes when exposed to a sustained ORP level of 800 to 865 mV. Kent Williams, Executive Director of the PPOA has long been hailing us with this fact from his "soap box", the Pumproom Press (please see PrP Issue 4, Fecal Water Balance: It Happens Every Day; PrP Extra Summer 1998, The Dreaded E. Coli bacterium; PrP Issue 6, Tech Talk: Crypto Update; PrP, Crypto Makes the News Again!).

When you're making a choice from the available water treatment arsenal, which would you rather; a weapon of mass destruction with a timely result, or a "fixed" weapon which kills only passers-by one at the time? I'm talkin' 30 minutes to 2 hours Contact Time (CT) with a system that is capable of delivering continuous ORP elevation (i.e. high capacity venturi feed) as opposed to 6 to 24 hours with "outboard" treatment systems (i.e. Ozone, UV). It's all good, but those of you with "The Solution" know what I mean!

"Godzilla's" lyrics repetitively finish...

"History Shows Again and Again
How Nature Points Out the Folly of Men"

Folly can be defined as a costly and foolish undertaking; an unwise investment or expenditure. Let's not let history prove nature right with this sobering indictment! We're not looking down the barrel at Godzilla here, right?!

"An Ounce of Prevention..."

2009-02-26T15:30:00.009-05:00

Benjamin Franklin is one of the most quotable people ever to color the pages of our American history. A few of his most memorable quotes include, "A penny saved is a penny earned", "Early to bed and early to rise, makes a man healthy, wealthy, and wise", and "God helps them that help themselves". Haven't you recently heard one of these in conversation yourself? He was a practical man; knowledgeable and useful in many disciplines. Although not a "pool guy", as far as we know, I believe he would be a profound advocate of preventative maintenance in the pump room today. His quote,

"An ounce of prevention is worth a pound of cure"

should be posted on the wall in the work space of every pool operator. Expending "an ounce of prevention" is essential to realizing that "pound of cure" for operators with "The Solution" on their wall.

The hard part is in remembering to routinely perform a preventative task when the demand hardly seems regular. I'm referring to that "once every so often" acid washing of the venturi. A great way to remind ourselves of regular tasks is to schedule them, right? Knowing when a task was last performed also adds to the level of awareness and further assures timely performance in the future. This is especially helpful when there are multiple parties responsible for completing the same task. Our friends at The City of Henderson (NV) have taken this concept one more step in placing a "last cleaned" notification directly on the face of their feeders. Very practical! The best thing about it is that this method removes the guessing and helps eliminate the eventual foreseeable venturi clogs. How's that for "an ounce of prevention"?

We like this idea so much that we're considering incorporating it as standard issue. Let us know what you think of this helpful hint with your comments!

Model Aquatic Health Code

2009-02-04T19:09:00.004-05:00

You are probably aware of the movement toward the development of a national model aquatic health code (MAHC) for recreational water venues, but did you know that you can participate in the process as well? The Centers for Disease Control and Prevention is currently taking applications for individuals who are interested in serving on technical committees to address future modules of this code. Go to http://www.cdc.gov/healthyswimming/MAHC/model_code.htm to download the application packet and review background information, vision and objective statements, as well as a diagram of the sequence of events being undertaken as part of the MAHC development process.

In October, the CDC released the MAHC “Strawman”, an overall outline of the envisioned MAHC. In addition, modules covering the first three chapters of the MAHC including the Preface, User Guide, and Definitions were included. A fourth module, providing guidance for responding to Fecal/Vomit/Blood contamination incidents is also available at the same link, www.cdc.gov/healthyswimming/MAHC/pdf/announcements/20081010_MAHC_news.pdf.

Encouraging Texas Public Pool Council members to get involved, Tom Vyles of the Plano (TX) Health Department said,

"before you think you are not qualified, take a look at the whole thing (MAHC Structure and Content). You may have some skills or expertise they need."

True too that we don't often have the opportunity to play a part in national policy making. Here's an opportunity to contribute to the model code your state's DOH may very well consider adopting in the future. A worth while consideration for sure!

"The Solution" is in AI's Top 20 Waterparks

2008-09-23T15:46:00.012-04:00

SureWater feeders are the feed system of choice for the top three, and four out of the top six waterparks in Aquatics International's 2008 Top 20 Waterparks list published in the September issue.

Number 6, Raging Waters in San Dimas, California installed their first Solution in January of 2003, then added a second system to their park in August of 2005. Number 3, Wet 'N Wild Orlando was the first waterpark in Florida to go with SureWater, installing their first of four feeders in June of 2003. Number 1, Disney's Typhoon Lagoon followed suit with the January 2004 installation of two Solutions, one each on their wave and river pools. Disney subsequently added three more Solutions at Typhoon Lagoon in 2005, and this year has placed Number 2, Blizzard Beach on SureWater feed systems with the installation of two Solutions. Isn't it great to know that as an owner/operator of "The Solution" Feed System, you are among some of the top operations in the country! Congratulations!

2006-04-20T11:20:00.000-04:00

How many times have you been working through a particular set of circumstances and thought, "I can't be the only poor sap who's ever had to deal with this situation"? Generally, when that thought has come to my mind, I wasn't looking much past my own "back yard" for an answer. Usually my short range pursuit would come back with a solution that would do the trick, and that was good enough. What might I find if I could expand my network beyond my regional interest group?

Over the past couple of years I've had the privledge of talking with some folks around the globe about their operations from top to bottom. The thing that keeps coming back to me is that no matter where we live on this planet geographically, or how diverse our cultures have developed, within the world of Aquatics we are one in the same. Whether its lifeguard shortages, water quality concerns, liability issues, or business finances, we are all looking at a very similar set of circumstances as we put on our work hats in the morning. It is comforting, in a sick kind of way, to know that there are multitudes of people in my industry that are dealing with the same challenges as me. Blogging can be an efficient way of hooking up with likeminded individuals all over the world. My (anonymous if I want it to be) concern, when aired in this blog, becomes a "jumping off" point for discussion that not only helps me with my concern, but anyone else in the world who happens to log on and read the dialog offered as well. So, with that having been said, Bon Voyage bloggers!

This is a great way for chlorine heads to get some "fresh air"- looking forward to posts. We went with Surewater 3 years ago and love it. Ending that bucket brigade was one of the best things about Surewater. We loved it so much that it is now on 6 of our pools. No fuss, no muss and balanced water....LIFE IS GOOD!

Chlorine and acid pumps

2006-04-18T13:58:00.000-04:00

Well I guess I am first to respond. I think this is a great idea. I want to talk about chlorine pumps. I have found a new type of venturi pump system manufactured by Surewater technologies. They are the designers for the "The Solution" it is a vacuum Induction pump used to pump your chlorine and acid. www.sureh2o.com check them out. I have a 3 million gallon flat water pool and I chlorinate and pump acid with them. They are hassel free and never loose prime. If you look at it you will love it.Tell them Mike Howard from Coney told you about it. I can't say enough about the product. Any questions or comments give me a call at work 513-624-1441.

End the "Bucket Brigade"!

And away we go! This endeavor is likely to be an interesting adventure into the minds of Pool Operators. It should prove to be a valuable resource to those who participate in contributing to its content. I don't believe there is any better way to learn than to hear it from the direct source, the proverbial "horses mouth". Wouldn't you rather talk to someone who's been there and done that. In my experience, that is where the true wisdom lies.

So, you've heard that it requires special procedures, and/or remedial products to keep combined chlorine in check in in-door swimming pools. All I know is that "I'm superchlorinating every two weeks and that don't cut it!" Somebody out there is having some success and not breaking their back (and budget) to get the job done.

Wouldn't you like to hear from an unbiased source when you have a similar question. You and your peers have nothing to gain from participating in this blog, except a chance to help out a comrade and maybe pick up a pearl or two you can apply yourself. Well, you get the idea. Bookmark this address , give it a look see from time to time and please comment. What you know could make the difference for someone else.
