I love the tarp on the ground idea. It’s a refinement on the old solar still, which took a lot of sweat to create. Thanks.

Excellent. You have described beautifully situations I have seen. Now I better understand what was going on. Thank you.

Excellent presentation. One thing, however: The 0.1 Sawyer Squeeze filter does not filter out viruses, which are much smaller. The Sawyer Point Zero TWO Purifier (.02) will remove viruses to 99.9997%, a 5.5 log reduction.

I’m enjoying your course. Been interested in water disinfection largely due to my outdoor activities, and also from working in a clinic in Honduras, and teaching people to use the Sawyer filters. With regard to contaminants, it seems to me one that is puzzling is cyanobacteria, or blue-green algae as it’s also called. When this stuff infects the water, it can be deadly to animals (and people) who drink it. Since animals aren’t put off by the ick factor of drinking nasty-looking water, they’re affected more. Most people aren’t going be be gulping down water that looks like green paint. Usually blooms only happen in the heat of summer. What is your understanding of blue-green algae? And can the toxins be filtered out? Looking forward to the rest of the course. Cheers.
