Frederick Miller Spring in Eden Prairie
The Frederick Miller Spring has been a popular drinking water choice for those who want an alternative to drinking municipal “city” tap water.

One advantage to drinking tap water is that cities are legally required to provide ongoing water testing and drinking water quality reports. You may not like the results of the tests, but the information is there.

With spring water, you never really know what you’ll get – unless you have the water tested! For that reason, we collected several water samples and had them tested by two independent laboratories.

Here’s what we found:

Frederick Miller Spring Water Quality Test Results

Spring water is sometimes described as natural, or “living water”.

The term “living” implies that there are “things” growing and thriving in the water source (Plant life? Microbes? The Loch Ness Monster?). Microorganism testing is organism-specific, and conducted ala carte which can become very expensive.

Our testing was done pro bono.

While we did check for Arsenic (which can be a health risk), the water testing mainly focused on aesthetic issues. Here what the labs found from the samples we collected on 11/1/2011:

Alkalinity: 240ppm
Test results are similar to most of the well water that serves the municipalities and private residences in the west metro area.

Arsenic: 1ppb
The EPA health limit for this naturally occurring carcinogen is 0ppb, but you probably won’t find that in this part of town. 1ppb is not bad, and is actually lower than many of the western Minneapolis suburbs.

Hardness: 20gpg
Lots of dissolved rock here (Hard water comes from Calcite, Gypsum, and Dolomite). Very similar to Minnetonka and Chanhassen city water.

Iron: 0.01ppm
Rust stains begin at 0.3ppm, so we’re good to go here.

Manganese: 0.003ppm
Black stains become noticeable at 0.05ppm, and higher levels of Manganese have been shown to lower the IQ in children. This passes the test!

Nitrates: 2.0ppm
Legal limit is 10ppm, so this test passes. Nitrate contamination, which is believed to have come from a nearby landfill, has caused levels to exceed legal limits in the past.

pH: 7.51
No acidic issues here. High pH would be problematic if there was more iron in the water.

Phosphates: 0.08ppm
Nothing exciting here.

Saturation Index: +0.38
This is a corrosion indicator. A positive number indicates this would “leave deposits” as opposed to more aggressive water that would “dissolve” plumbing in an attempt to reach equilibrium (0.00).

Silica: 26.2ppm
Nothing exciting here either (wouldn’t be great for a boiler or cooling tower though).

TDS: 468ppm
Water started at as a rain drop made of Hydrogen and Oxygen (0ppm TDS). This is a measure of everything that dissolved into that drop of pure water. To get an accurate Total Dissolved Solids measurement, you really need an accurate TDS meter that compensates for temperature. The cheap handheld meters can be off by +/-25%. We like the meters from the Myron L company.


Frederick Miller Spring Warning Sign
You now have a little more information about this water source to determine whether or not you’re comfortable drinking from it (or if it’s worth the gas money to go bottle up some water).

Would we drink it? Maybe if we were camping. In our homes? Probably not. Call us paranoid, but we get email updates about water contamination EVERY DAY! Today there are just too many toxic plumes for us to “consistently” trust an uncontrolled water source.

We’re also heavily biased as one of our primary services involves water purification for the medical and restaurant industries, in addition to homeowners.
