I think it's great that EESO has come up with a way to deal with one aspect of water contamination. However, I'm not ready to accept enzymes as a panacea. It's one thing to reduce the level of cyanobacteria; it's another to get rid of heavy metals, Giardia/cholera/etc, and chemical pollutants.
I'm a long, and I believe in the success of EESO, but I'm also trying to be realistic.
