The Sodis method is outright dangerous and I tell you why. All plastic bottles contain BPA and the ones that are BPA free have other equally noxious substances. Basically there is not "clean healthy plastic", even worse when you consider that BPA is released when the material is heated or freezed.

Name one person who has been seriously injured by BPA.
Personally, I got cut by a glass bottle and had to go to the emergency room. I'm not the only one to get injured by broken glass. Many have died.
While I'm not going to try this Sodis method, I'll take my chance with the plastic bottles.

Sodis with glass bottles:
"The results demonstrate that SODIS efficacy in glass under tropical field conditions is comparable to PET plastic. SODIS users in these regions can choose either of reactors depending on availability and preference of the user."

Kathy, some of the noted problems with Berkey is that they are riding on the coattails of British Bekefeld's well deserved reputation for quality products and have caused some confusion for consumers. Their black filters are shoddily glued on their plastic base and they may come apart, as well as leaks from the poorly fitted plugs.
Terracore I don't keep statistics on BPA deaths, sorry., But the health effects of BPA and even the new NON BPA substitutes in plastics, have been a well researched and documented issue that leaves little to argue about. It is said that we all have BPA in our bodies at this point. But it is the accumulation of BPA that represents a health concern. By all means stick to you bottles, you as well as I, are very capable to figure out what are the best choices for ourselves.

Sodis success using glass bottles citation.
Sodis style "solar disinfection" of water is well researched. And lots of articles on the internet about it.
Bpa isnt nearly as deadly as unsanitary water in the midst of a natural disaster.

It has been my understanding that glass does not work as well as plastic.

Thanks john,
well I relayed the info.
No problems so far in two years every day use, but we don't run gallons through per day. The filter is rated for something like 11,000 gallons at the rate we use it, which will be years.
Nothing has come unglued or leaked.
Ours is stainless steel of good quality, no rust spots, and the price was around $300.

Another Berkey supporter here. I've used one for a while to filter catchment for drinking with absolutely no problems, as have several other people I know. It's simple, it's affordable and it works. No one I've known who has actually used one for any length of time has had anything negative to say.
life is short. enjoy it

in a pinch, make a solar distiller. easy peasy...

Making a solar water distiller is easy if you have the food grade silicone to seal it with. And the glass for the top. And the food grade tubing to come off it. We have one from years ago and I am relining it for current use. On a sunny day it will put out three gallons or so.
Someone sure could start making these in Puna. No moving parts. As long as you keep it filled with water (catchment in our case) it will last many years.
Also as I mentioned on an older thread:
