Lead, microplastics, forever chemicals, etc - seems like a lot of things to be worried about when it comes to water these days. What is your source of water, how do you get your drinking water? Tap, bottled, do you use some kind of filter? And what do you think is the best way to get water?
I have refillable jugs and go to a filter station thing. There's a few different ones, and they usually list when they were last serviced. Most are just RO filtering with maybe some extra steps too. It's a reason to go run some errands a couple times a week.
I've started taste testing during the refill of the first jug recently after getting some water that was very off tasting from a station. Some stations are better maintained than others.
I might consider looking into an under sink RO filter though since that would be more convenient.
