My friends keep begging me to go swimming at this location. I’ve been told by locals that it’s not a wise decision. I was wondering how I can tell? I don’t think it’s about bacteria, but more there are a ton of boats, planes and former industrial waste in the area. Can I tell from these tests?

It is Lake Union A522 if it doesn’t link properly. Also, click all of the boxes to see the data and put in May through now to check the test.

FYI, I’ve seen people swimming there, they seem like tourists though.
