Who are you buying your water from? Do you test it before you brew?

 Dear Members,
 
 I have been a long-time inactive on this list because of a lack of time. 
However, I have been making EIS for many years.
 
 My problem is that the EIS  that I make now is brown.
 
 I used the Colloid Master AC with distilled water at 2 µS/cm. It was never 
even yellow until this year using all of the same water, apparatus and glass 
jar.
 
 It measures 23 µS/cm., so around 14.7 PPM.
 
 I use it in my Water Pic, but would like to try drinking and nebulizing it.
 
 Is there any solution?
