> To put it another way, would you want this waste water diluted and dumped in a lake you swim in or a river you fish in without proper study and regulation?

Are you going to apply the same standard to every house with a swimming pool, every municipal storm drain that collects rain water having passed over the ground in nature where there are untold strains of bacteria and every other system handling thousands of gallons of unfiltered water?

Otherwise it's an isolated demand for rigor.

You can tell that something has an ulterior motive when the rule or its enforcement special cases the doing of a generic thing only when it's being done by the people being targeted.
