tap water in surrey Question ?

[Ryanerickson]

I am in surrey mine tap water is always between 10-12 ppm never seen higher then twelve 100 ppm even if there has been a storm seems high. I had readings like that when I moved into the house I am in it turned out the main water supply coming from road was corroded we had it replaced with a poly line from the road now I never get higher then 12.
