As far as the camera crew goes, they do state, publicly, that the camera crew goes with him the first day when they drop him off, they take some shots, then leave him.
I wouldn't doubt that afterwards, if they see the need to inject something that is missing, maybe he took a bad shot where he is out of frame, perhaps they go back? I don't know? i don't look at it as them being deceitful, or lying to the audience.
I for one, first time I stumble on the show, and he mentioned that he does the filming, thought to myself, dang, get a non-interfering crew! That way you can concentrate on the matters at hand. But, obviously, that is not their intention. Then it would be just another "Here is how you do it" show.
Using sand as a filter is good if you can build a reliable device, and they suggest 2 to 3 feet worth of sand and/or you have confirmed that your water is tainted, such as in African villages where you can bank a 50% chance on cholera alone....ewwwww.
We are talking filtration of micro-organisms here. Not muck and brine.
Strouyd drank from a pristine stream, which flowed from uninhabited areas.
If the water were murky, sure thing, use your shirt, socks, whatever.
A thick Sock filter does better than a thin shirt anyway.
I would submit, in that remote location, if you filtered the clear stream water through a sand/shirt filter you would probably add more contaminants than you removed. A sand and dirt filter will NOT filter down below 10 microns, and that is on a good day, using plastic buckets and being able to screen and separate filter media into different layers separated by membranous material.
i don't think a sand/shirt filter would do squat for a clear water supply except add more chance for contamination.
I am going to post a an article about wilderness drinking water in a new thread. It should make for a good discussion.
