5 Simple Ways to Protect Our Waters
AdobeStock_33243648.jpeg

Wherever you are in the world, people need water to survive. 70% of the world is covered by water but only 2.5% of it is fresh. Depending on the region, some people flush out freshwater, while others are in drought and living in pollution. There are roughly 1.8 billion people in the world who don’t have access to safe drinking water, causing nearly 3.4 million deaths each year. A few simple adjustments in your daily routine can help make a difference in the water crisis:

Take shorter showers
3 out of 4 Canadian adults take 5 minutes long showers, using roughly 2 billion litres of water a day. Something as simple as shortening your shower to 3 minutes, can easily save 800 million litres of water a day, which equals to about 24 billion litres a month!

Don’t leave the water running in the kitchen
When washing the dishes, fill up one side of the sink to scrub your dirty dishes, and then quickly rise out on the other side. When rinsing fruits and vegetables, do it in a big bowl or pan to avoid water waste.

Dispose chemicals properly
Try to prevent any chemicals from going down your drain or toilet – whether it’s cleaning up paint, car oil, or flushing down expired medication.

Pick up after your pets
Pet waste left on the ground can run down the sewage drains, spreading bacteria and contaminating our water.

Your RV Tank May Be a Breeding Ground for Legionella

A flourishing RV industry means that each year, a growing number of North Americans are hitting the road in their homes on wheels. The majority of these RV travellers venture out seasonally, taking advantage of the warm summer months to explore new destinations, sometimes for long stretches of time.

While on the road, most RVers rely on local tap water or other municipal sources for their water supply and storage; however, there is evidence to suggest this practice may be putting travellers at unnecessary risk. Ambient temperatures and prolonged exposure to direct sunlight can produce conditions inside water reservoirs that are prime breeding grounds for bacteria, viruses, and other potentially harmful contaminants. While proper and regular disinfection can buffer against contaminant-related illnesses, many RVers are wondering: is there a better way?

 

Legionella in RV Water Holding Tanks

In collaboration with the United States Department of Health and Human Services, researchers at Georgia Regents University commissioned a study of RV water reservoirs following a case of pneumonia where both the patient and the reservoir of the RV he was travelling in tested positive for Legionella pneumophila. Organisms belonging to the genus Legionella have been clearly and repeatedly linked to contaminated potable drinking water, and tend to surface in high numbers when water is heated, unused, or under-chlorinated.

Data from the Collaborative National Waterborne Disease and Outbreak Surveillance System is proof that legionellosis is a growing concern for public health professionals, despite being entirely preventable. Between 2001 and 2006, Legionella accounted for nearly 30% of drinking water outbreaks and 80% of water-related deaths.

A research team travelled to three separate campsites and found that a staggering 20% of on-site faucets and RV water tanks tested positive for different Legionella spp. Researchers also spoke directly with RV users to learn more about their RV maintenance practices; these conversations revealed that RVers seldom use chlorine to disinfect their water tanks. Only 50% had performed any general RV maintenance over the past year, with only 60% spending the time to clean out their RV water tanks.

UV-LED Water Purification

Installing a UV-LED water purification system is a proven, effective way to keep yourself and your guests from getting sick (whether from pneumonia or other common waterborne diseases). Because improperly sanitized RV water tanks and weather conditions impact the quality of your RV’s drinking water, making sure water is free from viruses and other pathogens at the point of use is critical.

UV-LED: Mercury-Free Water Disinfection
UV-LED vs UV Lamp.jpg

Mercury is a naturally occuring and highly toxic element; so toxic, in fact, the World Health Organization named it one of the top ten chemicals of major public health concern. Even limited exposure can threaten the nervous, digestive, and immune systems, impairing function and often causing irreversible damage. Mercury pollution has devastating effects on the environment as well and of the estimated 5,500 - 8,900 tons of mercury emitted into the atmosphere each year, only 10 per cent is traced back to natural sources.

To address this global issue, in 2013 the United Nations Environmental Programme (UNEP) introduced the Minamata Convention on Mercury. This international treaty is designed to control mercury emissions and protect human health and the environment; since its inception, nearly 130 countries have come together and begun making changes to phase out a number of mercury products by the year 2020.

Mercury may be present in a number of consumer products, from batteries and barometers to automotive parts and thermostats. Most relevant to the water purification industry, however, is its prevalence in ultraviolet (UV) lamps. UV light is a proven way to disinfect drinking water, and while increasing numbers of water treatment facilities are adopting this technology, many are unaware of the potential risks and performance limitations associated with relying on conventional UV lamps:

  • High maintenance and operational requirements put users at risk of mercury exposure in the event of a lamp breaking or other accident.

  • Because mercury lamps require a longer warm-up time to achieve stable, high-performance results, UV lamps run continuously—even when there is no water flow.

  • UV lamps have a short lifespan, and must be replaced regularly.


At Acuva, we are proud to be part of the mercury-free movement. Since LEDs don’t require mercury, all of our UV-LED water purification systems are fully compliant with the Minamata Convention, offering a practical, effective, and scalable alternative to UV disinfection without the use of hazardous UV lamps.

Is Your Tap Water Safe To Drink?
Blog 5 - Hero.jpg

In North America, there is often the belief that living where we live means the water we use at home (an average of 300 gallons each day) is both clean and safe. We entrust water quality to our municipalities and other governing bodies, assuming that access to advanced water filtration techniques guarantees our drinking water is free of contaminants.

While it is certainly the case that water in developed nations like the United States and Canada are at reduced risk of contamination than in other parts of the world, it is still possible your tap water contains bacteria and other potentially harmful microbes. Where you live, how your home is plumbed, and whether your water system is fed from a private well or a public source all factor into the equation.

If you’ve ever questioned the drinkability of the water in your home, keep reading—you’re not the only one.  

 

2017 Water Quality Association (WQA) survey results

Approximately once every two years, the Water Quality Association (WQA)—a not-for-profit organization that represents the residential, commercial, and industrial water treatment industries—performs a national public opinion survey.

Survey results from earlier this year revealed some interesting insights around public perception of water quality and legislation:

  • 52% of respondents felt that federal laws governing drinking water in the U.S. were “not strict enough.”

  • 40% of respondents stated their drinking water was “not as safe as it should be.”

  • 36% of respondents were concerned about tap water contaminants, and a further 29% had concerns about whether their tap water was safe to drink.

  • More than half of respondents identified they would be willing to pay for a water treatment system that would remove contaminants such as lead, arsenic, and pharmaceuticals, and 25% stated they had intentions of installing such a system in the near future.

  • 41% of respondents who invested in a water filtration system did so after their home region was hit with a boil water or “unsafe water for use” alert.

As public awareness about hazardous contaminants and associated health risks rises, so, too, does the desire to protect against these risks by investing in a home water purification system that promises pure, great-tasting drinking water. Point-of-use or point-of-entry water treatment systems exist for precisely this purpose.

 

UV-LED: A smart, simple solution

When it comes time to make an investment, survey respondents identified a number of key decision factors: these include things like brand reputation, quality of customer service, level of product knowledge, and ease of installation and maintenance. Ultimately, however, what mattered most was and is protection and peace of mind.

There are a number of options on the market for purifying drinking water, and of these UV-LED disinfection leads the pack. Building on the successes of UV water purification, UV-LED systems satisfy homeowners’ requirements by offering a longer lifespan, lower maintenance requirements and lower power requirements.

What’s the Best Way to Purify Drinking Water?  
Blog Hero - What’s the best way to purify drinking water?  .jpg

Right now we are in the midst of a clean water crisis. Although 70 per cent of the earth’s surface is water, only 2.5 per cent of that is freshwater. And with our global population expected to rise to a staggering 11 billion by 2100, it is essential we turn our attention to making sure the water we do have access to is safe to drink.

A July 2017 report from the World Health Organization and UNICEF revealed that more than 4.2 billion people currently don’t have access to safe water sanitation methods. That’s nearly 60 per cent of world’s population.

As North Americans, we are fortunate to have access to some of the cleanest, safest water on offer. However, even we cannot escape the risk of illness and disease from waterborne pathogens. It is easier than you might think for drinking water to become contaminated at the source, along the pipeline, or inside a “safe” container.

Ultimately, disinfection is key. As technology evolves, so too do the options at our disposal for improving access and availability to potable water.

Here’s a look at what is currently on the market for consumers:

 

Chemical disinfection

Chemical disinfection uses oxidants such as chlorine-based compounds to rapidly react and kill some (but not all) harmful micro-organisms. Adding chlorine has been used as a convenient water disinfection technique for swimming pools and other household applications. While fast and effective, there are significant health and safety concerns. For example, chlorine-based components are corrosive and must be handled with extreme caution and care.

 

Filtration

Filters trap particles in porous material structures, but still allow water to pass through. This technique is effective for removing things like sand and rust, but it cannot address materials that have dissolved into the water. Though relatively inexpensive, the pore size of most filters is too large to trap microorganisms, so they end up passing through into people’s drinking water. They also require regular replacement, making them a high maintenance approach with only moderate effectiveness.

 

Reverse osmosis (RO)

Membranes, such as those used in reverse osmosis (RO) systems, are also considered filters. RO systems are a more effective alternative for removing microorganisms, but tend to be difficult to install, consume a lot of energy,  and have been found to waste up to 70 per cent of water post-treatment. Unfortunately, RO systems also strip water of its healthy minerals, taking the good with the bad.

 

Ultraviolet (UV) disinfection

One of the world’s most effective water treatment technologies, UV disinfection uses short wavelength radiation to deactivate microorganisms by disrupting their DNA. However, this technology is not without its limitations. Typically, UV lamps require replacement annually, along with monthly cleaning and maintenance requirements. Further, because UV lamps contain mercury and cannot be turned on and off (causing them to consume energy even when there is no water flow), their environmental impact has been the subject of much controversy.

 

UV-LED disinfection

Following careful observation of these and other techniques, scientists introduced a revolutionary technology known as UV-LED. With a longer lifespan (10+ years on average), low power requirements, and low maintenance requirements, the characteristics of UV-LEDs produce an optimal disinfection efficiency and is fast becoming the go-to source for water purification.  

It’s no surprise we’re particularly endeared to this form of water purification. In fact, you’ll find it in all of our Acuva purification systems.

No matter whether you’re gearing up for a month-long adventure in your RV, heading out to the cabin for the long weekend, or cozying up at home, keeping yourself and your loved ones safe and healthy is always a priority. As a business based on transparency, we believe in providing honest, accurate information to help you make the best decision for you.
