if you care about your family and loved ones, find them alternatives.
the standards are a joke even when followed.
even the safety of showering with tap water is questionable.
if you care to research, of course... there,s always sticking your head in the sand.
Why is this?
> I have trouble taking any health advisory seriously
Please keep in mind you're not talking to the person that made a health advisory. You're talking to someone who is saying why it's possible for water to be unsafe to shower in.
In Seattle it's basically raw snowmelt with 0 metals (had mine tested for heavy metals, register 0). Lots of places in the US have perfect water even if you don't trust the EPA's warning thresholds.

But that does not happen unless the municipal water source changes day-to-day, or is catastrophically badly run in a really inconsistent manner... which is almost never the case in the US. Even in Flint, it's not like the water changed day-to-day; it just became consistently acidic, which pulled lead from pipes.
Aquifer-pumped water is consistent, reservoir-fed water is consistent, groundwater is consistent.
(also personally the contaminant I'm least fussed about)
Of course, this article is about water that is potentially hazardous which is a real problem.
