Author’s correction to the original article — “The Universal Solvent” — as published in the Summer 2018 issue of Hand Papermaking:

You’re right about the situation in the USA being complicated. When I was with a UK water and environmental consultancy a couple of years ago, one of the projects I was working on involved contacting all 50 States to determine what their approach was to drinking water quality. Even now I don’t think I fully grasped the situation! Just for your interest (and maybe the information could be useful for your paper), the following quotes are taken from the US Environmental Protection Agency’s (EPA) website:
It’s interesting to note that “although state health agencies and public water systems often decide to monitor and treat their supplies for secondary contaminants, federal regulations do not require them to do this”, despite the fact that many of the parameters could have an adverse impact on papermaking.
This paper gives a good insight with some of the things that can readily go wrong with paper that may be attributable to metal contamination:
