If you can detect any, it's too much:

On Tuesday, the Environmental Protection Agency announced that it had started the process that will see drinking water regulations place severe limits on the levels of several members of the PFAS (perfluoroalkyl and polyfluoroalkyl substances) chemical family. PFAS are widely used but have been associated with a wide range of health issues; their chemical stability has also earned them the term "forever chemicals." The agency is currently soliciting public feedback on rules that will mean that any detectable levels of two chemicals will be too much.

PFAS are a large group of chemicals that have uses in a wide range of products, including non-stick cooking pans, fire control foams, and waterproof clothing. They're primarily useful because of their water-repellant, hydrophobic nature. That nature also tends to keep them from taking part in chemical processes that might otherwise degrade them, so contamination problems tend to stick around long after any PFAS use. And that's bad, given that they seem to have a lot of negative effects on health—the EPA lists cancer risks, immune dysfunction, hormone signaling alterations, liver damage, and reproductive issues.

[...] The most striking thing about the proposal is that two of the chemicals, Perfluorooctanoic acid (PFOA) and Perfluorooctanesulfonic acid (PFOS) will be set at the limits of our current ability to detect them: four parts per trillion. In other words, if there's any sign of the chemicals present, it would be above the legal limit. (Both of these are acidic hydrocarbons where all of the hydrogen has been replaced by fluorine.)

A second set of related chemicals (PFNA, PFHXs, PFBS, and GenX Chemicals) will be regulated as a collective. Each will have limits set on the levels allowable. The levels of each will be calculated as a percentage of that limit, and the percentages totalled; if they exceed 100 percent, then the regulations will kick in.

As part of its earlier efforts, the EPA has already been providing grants to help water utilities set up to test for these chemicals. It also says that a variety of means of extracting these chemicals from water are now available.

    There are 2 problems with having producers pay for damage done in cases like this. One is that the damage can't really be proved for pollution levels slightly above the legally specified limit. The other is that juries are notoriously bad at judging actual damages, and tend to award payments several orders of magnitude too high.

    There bias evident in your post. "...the actual, real cost of producing what they produce. Maybe we should make that extremely expensive instead." Implied here is making penalties far in excess of damage, of making the cost much greater than the "real cost."

    W.r.t. the bias: the comment is aimed at the frequently held belief that if costs can be externalized, doing so is not immoral.
    Certain things just shouldn't be done, full stop. Society has no duty to give handouts to destructive entities.
    This is aimed against the strawman of "making us pay for X will put us out of business" to which I say: then maybe you shouldn't be in business.

      Regulation is itself an externality. When done well, it counters existing externalities to effectively eliminate them. When done poorly, we get stuff like this.

      Extremely costly regulation is such a thing. Society has no duty to give you a handout when you think something should be overregulated.

      the comment is aimed at the frequently held belief that if costs can be externalized, doing so is not immoral.

      So what? Laws aren't for the purpose of punishing beliefs you don't like. We can completely eliminate the moral dimension altogether by eliminating the externality. The approach of eliminating the opportunity to do wrong is straight-forward and far more powerful than merely punishing people.
