Title: Recent water report for the Leixlip area
Post by: Dr Jacoby on March 11, 2016, 12:31:07 PM
Hi all, I'm putting together some info on water treatment and I was hoping to find a hard water profile to use as a sample case. Do any of you have a recent water profile for the Leixlip area (or surrounding regions) that you'd be willing to share? It doesn't matter if it's just a snapshot in time. I'd rather have an accurate snapshot than one that averages the readings out over time. Your help would be appreciated! Peter

Thanks Oblivious! That report won't work though. It gives ranges not specific readings  :-X
