I'm reviving this thread cause I'm also moving to Denver and am about to get brewing.
Has anyone else looked at the treated water profile report from the city? It's a great document.

Things I've learned so far:
1) The water comes from 3 different sources, The Foothills plant, the Moffat Plant, and the Martson plant. Here's a quote from the report:
Which Treatment Plant Serves
My Area?
Denver Water's distribution system is completely
integrated. This means that we can distribute water
from any of our three potable treatment plants to
anywhere in our system. Water is usually routed
based on demand. Foothills Treatment Plant is
our largest gravity fed potable water plant. It is
often in service and serves much of the system.
However, we can blend water from Foothills with
Moffat or Marston or blend the water from any two
potable treatment plants and send it anywhere in our
system. This complete redundancy is rather unique
compared to other distribution systems in the United
States. When wondering which treatment plant
serves you, it is best to assume that the water can
come from any of the three treatment plants to your
home or business at any given time.
That makes me consider using the Foothills specific numbers as a base approach, but is also a reminder that the water will never always be exactly the same.
2) The average pH for the Marston and Foothills plants is roughly just over 7.7, while the Moffat plant averages closer to 7.85
The tables with the specific numbers are a little annoying to import, but the PDF for 2013's report has a lot of information.
There are a number of disinfection byproducts in the water including
Bromochloroacetic acid Bromodichloromethane Chloroform
Cyanogen Chloride Dibromochloromethane
Dichloroacetic acid
Haloacetic Acids (5)
Total Trihalomethanes
Trichloroacetic acid
I am still learning a lot about water (and getting into the palmer book) but from what I've read an activated carbon filter should take care of most of these chemicals. I got a 5M carbon dupont filter setup that I'm going to semi-hard plumb into my system.
