Great writeup, but I did have a little chuckle reading "it was taken about near here", followed by coordinates precise enough to identify a single atom. https://xkcd.com/2170/

I'm not sure it's quite enough. By my calculation a change of one in the last digit corresponds to a move of about 1 nm. A water molecule is about 0.27nm across. I think you'd need at least one more digit.
