Viewpoint: COVID-19: What’s Next

Wednesday, July 15th, 2020

Kurt C. Peterson, Publisher

As the pandemic continues to confound scientists and health officials alike, we are left with a patchwork of state-by-state regulations and guidance. A one-size-fits-all approach will not work when there is such diversity of population. For larger metropolitan areas, the close proximity of living and working conditions highlight the risks. For those in rural areas, the risks might seem different but the outcome of infections are quite likely the same. Be it personal life or business, nobody can escape the reality this has brought to our doorstep.

NSF International, WQA, Underwriter Laboratories and others have put a lot of effort into drafting possible solutions to reopen businesses safely, outlining disinfection and personal protective equipment requirements, as well as reassuring both clients and employees that their safety is a top priority. There are so many considerations to be made, including how to deal with the possibility of lawsuits if someone contracts the disease in your area of operations. Reopening must be based on facts rather than fear, though there is little enough to guide one to the optimum result.

That COVID-19 will be with us for the foreseeable future is not in question. How to salvage business from the total disruption of society on a global basis is somewhat murky. The level and amount of preparation required to reopen the business world may well carry a bigger price tag than we can yet imagine. Please let us know how you are proceeding, what precautions you have in place and how your clients are responding to your efforts.

Reverse osmosis technology has been at the forefront producing safe, high-quality water for decades. Even though there is no indication that COVID-19 has been found in water supplies, RO’s ability to remove almost all contaminants could be a factor to drive more innovation and sales. We have two articles about RO this month. Canature Water Group’s Toby Hughes delves into the problem of reject water and waste, while WC&P Contributing Editor David Martin reminisces about RO pioneer, Donald Bray.

With attention focused on global water scarcity and the impact that will have on future water supplies, water reuse and recycling has been gaining in popularity over the past decade. As such, the NSF/ANSI 350 standard was created to help manufacturers take advantage of this water-saving technology. NSF’s Sharon Steiner provides insight on water scarcity and how the standard applies to current conditions.

Public Health Editor Kelly A. Reynolds, MSPH, PhD, takes a closer look at how to prevent the spread of COVID-19 in the workplace and at home. She focuses on best practices that can help to reduce exposure risks while dealers are interacting with the public and transitioning back to life/travel.

Each month, more events are cancelled, postponed or turned into virtual events. We are trying hard to keep up with the changes that occur on a daily basis. Please note those changes in the Upcoming Events section and if you know of an event status that has changed, please let us know. We strive to keep the most in-depth calendar available in print and online for our readers and we hope that before too long, we can remove the special identifiers we’ve added and can see you in person again. Until then, be safe, be sensible and good luck.

Remote-controlled track drill

Monday, June 15th, 2020

Lone Star Drills introduces an all-new tracked drill with an automatic SPT hammer for improved accuracy in geotechnical and soil sampling applications, based on the popular LST1G+HDA. Operators can position the drill in hard-to-reach areas and locations with delicate underfoot and maintain leveling control with hydraulics. The drill was designed to address the growing demand from customers wanting to access remote or environmentally sensitive areas. The tracks spread the drill’s weight and lower its ground pressure to 3.8 psi, minimizing the risk of damage to the underfoot. The tracks also minimize the risk of the drill getting stuck in soft ground conditions. The remote is battery-powered and includes a 50-foot (15.24-meter) tether cord in case of battery power loss.

Kearney new IWSH director
The International, Water, Sanitation and Hygiene Foundation (the charitable arm of IAPMO) has promoted Seán Kearney to the role of IWSH Managing Director. Since joining The IAPMO Group in 2015, Kearney has overseen development of the international Community Plumbing Challenge (CPC) program, which has grown into the flagship initiative of the IWSH Foundation today. Over the past five years, he has directed projects launched in India, South Africa, Indonesia and most recently the US. Following his education at the National College of Art & Design and Trinity College (both in Dublin, Ireland), Kearney represented the Emerald Isle as a competitor in Graphic Design Technology at the WorldSkills international competition in 2005. His participation led to work with WorldSkills, initially as a volunteer before employment as a workshop manager, secretariat and project developer, gaining project management experience in countries across Europe, Asia, Africa and South America.

He worked for the WorldSkills Foundation during its start-up period from 2013-15, during which time the Community Plumbing Challenge concept was established, alongside several other skills showcase projects and sustainability initiatives that Kearney has continued to develop under IAPMO’s WorldSkills Global Partnership to this day. Most notable of these was the recent Plumbing and Heating Champions initiative, presented in Kazan, Russia last year, which resulted in the international skills competition providing new toilet and washrooms to a local orphanage for special needs children.

In his new role, Kearney will provide additional strategic and organizational leadership across the IWSH team, as the foundation further grows its reputation and expands its impact in the international water, sanitation and hygiene sector. He continues to provide guidance to the design and delivery of other international programs and partnerships of The IAPMO Group.

Viewpoint: It’s not the end of the world

Monday, June 15th, 2020

Kurt C. Peterson, Publisher

In prepper communities and groups across the globe, there is an acronym that has gotten renewed attention as the COVID-19 pandemic continues to wreak havoc. TEOTWAWKI, the end of the world as we know it, is not all encompassing, however, no matter what some elements of society preach. In most places, the societal norms have been modified but not (for the most part) abandoned. Collapse of society is not eminent. But we do have to step back and look at how our consumerist society has been turned on its head. Listen to the news for more than a few days and we hear about how the inability to shop is having a major mental health impact and social distancing isn’t helping ease the feelings of isolation.

The world is not at its end, we won’t implode if we can’t go out for a night on the town and while many businesses may end their existence due to factors beyond their control, most will quietly rebuild their sales teams and product lines to factor in the influence of the pandemic. Whether it’s the hospitality industry that has been brutally crushed or the manufacturing companies who are thankful to have operations in the US rather than offshore, the resiliency of the American capitalist may be slightly muted at the moment but it has not been silenced. Technical Reviewer Peter S. Cartwright, PE, offers his perspective on what is happening in the COVID-19 world and our lives, based on his decades of water treatment expertise.

As an essential industry and a public health player, water treatment is still badly needed. Treatment options will continue to emerge in response to whatever happens next, as it always has. A basic component of water treatment that stretches back into the earliest societies, carbon is still at the forefront of a great many treatment systems. Gary Battenberg, of Dan Wood Co. treats us to a primer on the do’s and don’ts of using activated carbon.

There are many interlocking and overarching aspects of water treatment, including plumbing, though it can often be overlooked. While it is a critical element of commercial enterprises, plumbing and the associated regulations are not always at the forefront of a water specialist’s mindset…until he hits a permit brick wall in a state requiring a plumber be involved. Thomas Palkon of the IAPMO Group delves in to the ASSE 1087 standard to explain what is required in the crossover between water treatment and plumbing for commercial and food-service operations.

As states begin allowing more and more businesses to reopen, there is revelation about water safety (or lack thereof) in buildings that have sat idle for the past couple of months. You can’t just turn on the tap and expect water quality to be the same as it was before the tap was turned off. Public Health Editor Kelly A. Reynolds, MSPH, PhD, reviews the processes and procedures by which all building managers can ensure they do not make a bad situation worse. Building water supplies are at risk from stagnation and contamination, creating a public health hazard for businesses and inhabitants alike. It’s a good read with many salient points for those wishing to get back on track to reopen as soon as possible.

More events have been cancelled, postponed or are being held virtually. No, it’s not the same convention experience, but the focus on education remains the same. If you can take advantage of any educational seminar or training session, do it. You never know what you’ll learn next and how it will be of great benefit to your clients, down the road. Be the edge instead of trying to find a fancy slogan to give you an edge. Now more than ever, you are critical and essential to the well-being of our country and others that you serve. Be there for them, now and in the future.
