That being said... on the linked page it says:
> Outflow water has been sampled after every use of the system and consistently shows negligible traces of any contaminants, and specifically, that all levels have remained below standards for all state permits that would authorize discharge. TCEQ, the FAA, and the U.S. Fish and Wildlife Service evaluated the use of the system prior to its initial use, and during tests and launch, and determined it would not cause environmental harm.
Is this all lies?
