Giardia lamblia cysts/L none 0.007
Molybdenum ppb none < 0.5
pH (distribution system) s.u. none 7.4 - 9.1
pH (plant effluent) s.u. ≥7.4 7.2 - 8.5
Silica (dissolved SiO2) ppm none 4.1
Sodium ppm none 6.3
Temperature (varies seasonally) °C none 4.5 - 21.8

You are missing most of the info needed for brewing. Such as: Calcium, sulfate, chloride.
you do have the total hardness as CaCO3 and the sodium. If you want a complete picture of your water, you'll probably have to send off a sample to http://www.wardlab.com

These are some of the ones you need, you're still missing magnesium and calcium. The calcium is quite important. What are the 2 columns of numbers for? Is one an amount and the other a maximum or something like that?


Chloride ppm 250 2.4
Sulfate ppm 250 3.5
Total Hardness (as CaCO3) ppm none 11
Sodium ppm none 6.3

Does Ward provide a comprehensive list or do you have to specify the criteria you are looking for?

Others are right that you definitely want your Ca++ and Mg++ concentrations. But, judging by your low sulfate, low alkalinity, and low chloride levels, I'll bet Ca and Mg concentrations are fairly low as well. From what you have, I'm guessing it's very soft water and low alkalinity. Might be good pilsner water

To get my water report I just called the local water authority and told them specifically what I was looking for. They test each year for the EPA, so they should have the information and you should have access to it as a customer. And also find out if and how often they switch their water source. The alkalinity of my tap water here ranges between 100-220 ppm depending on where it's coming from. Makes things a little tricky.

Here's a list of the more important items you should pay attention to:

Calcium
Magnesium
Alkalinity
Sulfate
Sodium
Chloride
Chlorine
Chloramine

Great, thanks for the reply. I'll just give them a call and ask for specific information.

So, did you get the specific numbers? since we're in the same area, would you mind sharing your results?

thanks

Hey Kevy,

Since posting this, I've actually moved out to Monroe, so I'm in the process of getting the snohomish county report. I didn't call for the Kirkland report, sorry!
