I'm not where I can get to a computer, but as I recall you can do this with a line graph by opening the formatting option on the X axis and setting it to be a date.
Maybe it depends on where? I've lived here all my life and the water quality has always been excellent. But my understanding is that, because the county is so huge, different parts get their water from different sources. So maybe I'm just fortunate to live in an area that's good.
I knew a girl who was raised in a small town in the middle of nowhere, without TV or movies, but she read a lot. She had so many things like that. Yosemite rhymed with hose-mite.
They say it that way because in the US that's how it's pronounced. The argument that it's pronounced differently in other countries, so the US way is wrong, is stupid. Even within a language/country, there are regional dialects.
I grew up in the US, but my dad was from England. There were lots of times I said a word the way I had always heard my dad say it, only to have people correct my mispronunciation. The one that pops into my head was capillaries (the little blood vessels). My dad always said ca-PILL-ah-rees, not CA-puh-lar-rees. Neither is wrong, it's just pronounced differently here and there.
I would personally like to see more support from other countries, just like I hope I would stand up for my invaded neighbor in my hypothetical scenario. I would not reward Putin in any way or he'll just do it again with another country.
The salient part of my analogy is that his "investment" is in being completely in the wrong by every measure. No one should support him continuing on the path he's been on.
So was it a government (state or federal) water treatment plant? If so, I can tell you how it happened. The government contracting agencies have boilerplate text they're supposed to add to contracts to make sure salient requirements get flowed. They're supposed to delete or tailor anything that doesn't make sense, but the contracts people aren't usually very technical. We had requirements flowed to us about password management and account monitoring, but no one logs into a rocket engine or a torpedo. When we'd point it out, they'd say "oops, we should have deleted that."
Oh, I haven't noticed that.
