For your use, includes average tap water temps if you're chilling.
And this is what I got regarding what water is in my Manitou neighborhood:
The primary source for your area will be the Green river and the North Fork well field. During the winter there is a chance that you could possibly see some well water from our in town wells as we use well water to supplement green river water when the winter rains bring higher turbidity to our primary source.
Tacoma water uses chlorine to treat our water.
The well at 74th and Cedar is still available for non-fluoridated water, but is chlorinated as required by law.

Cheers, and happy brewing!
