We learned that our water authority (as many municipalities do) adds phosphate to our drinking water to (and this is the OFFICIAL term used in literature) “DE-GUNK” our old infrastructure. I cannot help but wonder if this routine procedure is ADDING to HABs like this.

I bet you are right. Years ago, I did some work on clarifiers. The curse to the sanitary departments was phosphates. That was the only thing in their process they could not remove and the big push was on to get it out of detergents. Those levels are insane. I think you are on to something more than the stock excuse of farmland runoff.

During college I also worked for a pool company in Pittsburgh. Did a lot of lab work. Testing was much more primitive and slower in those days. I can only imagine the equipment now.

Our computer testing (Pinpoint) is fairly sensitive. My employer has used several different phosphate testing methods (as again, we were/are getting INSANELY high phosphate readings. They ALL registered at the same levels). Worse concentrations, fresh fills. The multiple suppliers that we buy from have ALL had Phosphate Remover stock issues.

For places/areas/pool owners who don’t get water professionally tested, high phosphate levels (ie, no chemistry used to remove from suspension) it would be called “high chlorine demand.”
