GVRD water quality

[Slyguy00]

So about a month ago, I tested my tap water and it was coming out of the tap at 220 ppm. After the RO it was reading at about 10. I thought that was pretty good. Until I tested today and the tap water is now reading 10, and after RO it is at 0. Im just curious to know if this has happened to anybody else locally? Good to know our drinking water fluctuates so much. I guess that would explain why my sediment filter went brown so quickly.
