Water Treatment 101: Bacteria

Feb 11, 2015

Bacteria are everywhere—on you, in you, in the soil, and yes, even in the wilderness’ cool, refreshing water sources. In fact harmless species of these single-cell organisms exist naturally in the backcountry’s rivers and pools. But humans and animals can carry harmful bacteria as well, and spread these pathogens to the water, making it risky if you happen to drink from the wrong place at the wrong time. Some of these bacteria are the same notorious headline grabbers associated with foodborne outbreaks or epidemics after natural disasters. We’ll discuss those and others, but first a few general facts.

Water Treatment 101: Cryptosporidium

Feb 10, 2015

Research backcountry water treatment and you’re sure to be warned about cryptosporidium or “crypto.” And for good reason. This microscopic protozoan parasite is one of the most common causes of waterborne disease in humans in the United States. Like the parasite giardia, crypto is found in water sources worldwide, and affects individuals differently. Fortunately, the disease it causes is rarely life-threatening in healthy adults. In fact, some 80% of the U.S. population has had cryptosporidiosis at some time, according to the FDA. Still, its symptoms are nasty enough that you’ll want to take strides to avoid it on your next backpacking trip.

The Gear Institute Tours MSR’s Water Research Lab

Nov 6, 2014

Earlier this year, we gave you a behind-the-scenes look into the world of MSR’s on-site water research lab in this article. The microbiology lab was established in 1997 and has been dedicated to quality control, as well as researching, developing and testing water treatment solutions for outdoor users, the U.S. military and citizens in developing nations ever since. Recently, The Gear Institute stopped by to take a tour of the facility and find out why we go through such thorough testing on our water treatment devices. You can read all that The Gear Institute learned here.

Backcountry Water 101: Danger Zones

Oct 16, 2014

After a long day trekking in the backcountry, that idyllic, trickling stream may look extremely tempting, but a cool sip isn’t worth the risk of ingesting waterborne contaminants. The best way to greatly minimize the risks of infection is by treating backcountry water with a filtration or purification system (more on that later), but you should also educate yourself about the wilderness water contaminants that pose immediate threats to your health, and the backcountry “zones” in which you are more likely to encounter them.

Water 101: Clean Water Solutions to Prepare for Any Emergency

Sep 15, 2014

Water is our most important resource, but you never know when a disaster could compromise your local water supply. Whether you live in the city or in a more remote area, having a way to get clean water is crucial to keeping you safe from additional harm. In honor of emergency preparedness month, we’ve put together the information you need to ensure you have access to water that’s safe to drink. Clean water threats When drinking water is contaminated in municipal or developed areas, the immediate threat to human health is the introduction of waterborne pathogens—microscopic disease-causing bugs. These include bacteria, protozoa and viruses, all of which are normally removed by the city treatment center long before water ever flows out of your tap. In a disaster situation, contamination of…

A Commitment to Safety: Inside MSR’s World-Class Water Research Lab

Aug 11, 2014

Behind every MSR water treatment and hydration product is a team of scientists dedicated to researching, developing and testing the latest in water treatment solutions. Established in 1997, our on-site microbiology lab is crucial to MSR’s water program and the safety and reliability of our products. Initially founded to ensure quality control, today the lab’s world-class efforts stretch into research of new technologies, testing and development for the U.S. military, and contracts with nonprofit organizations working in developing nations. The lab is located at our Seattle headquarters, in close proximity to our production lines, and is staffed by five scientists with advanced degrees in chemical engineering, biochemistry, microbiology, environmental science and cellular and molecular biology. The world inside this small space is fascinating, with an incredible amount of scientific knowledge….

School’s Out for Winter: SnowSchool’s Outdoor Science Classroom

Feb 7, 2014

This January, 70 elementary kids filed out of Boise’s Bogus Basin Nordic Center in groups led by SnowSchool volunteer guides. They were bound for the surrounding wilderness and the educational wonders it held. As they ventured through the forest on snowshoes, they caught glimpses of Treasure Valley and the Seven Devils Range in the distance. Along the way, they stopped to learn about the area’s plants and animals, discuss its ecosystem, and conduct a snow pit analysis. For many students, this was their first time snowshoeing—and their first visit to a national forest. For 10 years, the SnowSchool has aimed to introduce students, often those underserved, to winter’s landscape and ecology, and foster an appreciation for nature, as well as a healthy, active lifestyle through snowshoe recreation. Every year, the…
