Full disclosure: I am on the management team of a water utility in NY - I’m info systems and security, but have been working at utilities since I started working nights during college in 1983 so I’m not a water safety expert but I’ve learned a few things through osmosis. (water utility joke alert)
It is up to states to be diligent about testing, so I’m sure (as that report suggests) there are places that have better control of potable water standards than others.
PFAS are the big gorilla right now from the media and public awareness perspective. Here in NY we’re actually spending a ton of time and money to install systems to mitigate them.
The state created a crazy rule where the limit allowed in water was going to require treatment systems that did not even exist in production yet and couldn’t be installed without major upgrades that would take many months and/or years, and would cost hundreds of millions of dollars across all providers - but was set to go into effect immediately. Luckily they suspended the requirement for a short time, so now everyone is in rush rush mode.
But, whenever the tap water / bottled water thing comes up, I have to point out that the rules and testing for bottled water are FAR below what we have to do as public water suppliers:
And… SURPRISE, many bottled water companies use public water system water and bottle that. (Coke’s Dasani water used to use the wells in Queens NY from the private company I worked for back in the 80s and 90s.)
