People with experience working in and around municipal water infrastructure: Do you drink tap water? Are there times when you do not?
This question is obviously intended for those that live in places where tap water is "safe to drink."
I live in Southern California, where I'm at the end of a long chain of cities. Occasionally, the tap smells of sulfur, hardness changes, or it tastes... odd. I'm curious about the perspective of people that are directly involved and their reasoning.
I manage utility services - among other things - for a group of properties - and have had the mains water analysed for chemical and biological contamination at various times. The results have always been absolutely fine. Not just with EU limits, but far, far, far within them for almost everything and definitely well within them for all measures.
I've got no issues at all with drinking tap water in the UK, even given the state of the rivers etc.
We have used ALS Testing in the past. More recently Latis Scientific. Both have been good, we swapped just because of some internal admin thing at one point.
