This says there may be healthier versions

either way you'd be ignorant to ignore multiple third party studies
recorded
in the scientific community proving safe in some cases (de chlorinated tap
water) and not others (regular tap water) or just not passing state safety
standards because federal ones dont exist yet

That is correct. Federal standards are for food contact. There are
other organizations like the Consumer Products Testing Labs and NSF for
drinking water contact:

Most local agencies find this acceptable for their local use.

As for any material there are acceptable levels of contaminates. Now
that we can measure down in parts per trillion that does not mean that
only one ppt of practically everything can cause cancer.
