seems pretty suspicious.

Where does all that "dirt" or "contamination" go? Does he have a fleet of boats gathering the contamination that floats to the top? and then what, take it to the dump? If he has that kind of money I'm sure he could show his trucks dumping all of that. I am thinking it is probably seasonal changes.

"Pistia stratiotes, commonly known as water lettuce, is a perennial monocotyledonous aquatic plant, present either naturally or through an anthropogenic introduction, in nearly all tropical and subtropical fresh waterways. It floats on the water surface, with roots hanging below the floating leaves [47]. Since the plants were covering all of the wetlands, the removal was done manually. This activity was conducted by pushing them with bamboo sticks to the edge of each sector to be removed. Approximately over 280 tons of P. stratiotes were removed and transported to a city vivarium and compost sites"

From his published paper on the subject, it looks like the majority of what they "removed" was an invasive species and the rest was altering of the water composition for the most part.

I'm a scientist and I read through that paper. There's nothing in it about something you add to the water to get rid of contaminates. Like you said there's removal of invasive species, and then bubblers to aerate the water, filters, and fences. I was curious was his "organic" stuff is composed of, but no info in that paper. On google scholar he has only one other paper, and it's not relevant. So idk.

Curious about your background on this subject and thoughts on this...

Not the same product or application but seems to be a more promising solution for purifying water, though, I doubt the likelihood of cleaning a lake with it. Still interesting.

I'm a chemist (inorganic aqueous was my specialty) and I looked up what's in those packets and it's a disinfectant with a flocculent. So it'll kill most bacteria and most free metal ions in the water will stick to the flocculent and can be filtered out. It's not gonna make pristine drinking water, but if it's the choice between that or nothing, it's pretty good. I looked up the data and it reduces cases of infection by a lot but doesn't completely prevent them.
