I don't have any of my reference books with me, but here are the numbers on our well water tests from Ward Labs:

Test 1 is water through our water softener
Test 2 is through a sediment and carbon filter, but no softener

T 1 ---- T 2 ---- (type)
5.9 ---- 6.1 ---- PH
113 ---- 112 ---- Total Dissolved Solids (TDS) Est
0.19 ---- 0.19 ---- Electrical Conductivity, mmho/cm
2.0/1.9 ---- 2.1/1.7 ---- Cations / Anions, me/L
(rest below is in ppm)
40 ---- 7 ---- Sodium, Na
<1 ---- 2 ---- Potassium, K
5 ---- 26 ---- Calcium, Ca
<1 ---- 5 ---- Magnesium, Mg
13 ---- 86 ---- Total Hardness, CaCO3
<.01 ---- <.01 ---- Nitrate, NO3-N
<1 ---- <1 ---- Sulfate, SO4-S
4 ---- 4 ---- Chloride, Cl
<1 ---- <1 ---- Carbonate, CO3
109 ---- 94 ---- Bicarbonate, HCO3
89 ---- 77 ---- Total Alkalinity, CaCO3

What do you think?

I had them both tested in case they would be useful for different profiles I was looking for, or as blends or something. Both are convenient for me to use. Both also taste great.

Should I plan on adding any distilled or RO for a bohemian pils?

I have a similar water profile as yours, except mine has a lower total alkalinity and hardness. mine has a extremly low calcium levels and was creating a muddy sweetness in my beers. People recommended Palmers How To Brew website and I highly recommend you read that and get his spreadsheet for water adjusting a brew based on SRM or target water. When I plugged both your water profiles in it spit out a SRM range for 10 -17 based on residual alkalinty. For a pils I think you want soft water and a low residual alkalinty so it may be better to just go buy some Deer Park or another soft water. Im still a baby learning this stuff so take my advice with a grain of salt.

I posted a spreadsheet that uses Palmer's formulas and does an optimization of additives to get your water to where you want it - works as long as you have the Solver add-in loaded in Excel. It also has a graphical depiction of his nomograph output for your water. It is in the software forum somewhere.

If your water stays at these figures then you are ok to treat your water and will get good results but my water changes because of several water sources contributing to the water supply for my area. I would have to test here all the time to know what I am working with. I guess I don't have much control over it and that is why I use 5.2 PH Stabilizer now by Five Star Chemicals.

I just realized BeerSmith has a water tool. Using it, if I cut with 3 parts distilled to 1 part water, I can get very very close to pilsen.

Now the trick will be researching a solar still that can be made from parts I have in the house.

This may be a dumb question but where can you take water samples to have them tested? Cost?

I got the W6 test and I think it was $16 a pop. I had my indoor water (softened) and my garage water which I rigged up the prefilter and carbon filter for.

The guys there were a little late with my test results and we called and found out that they had no power for 10 days after a tornado hit them. They might be a tad slow right now, but they give you basically exactly what you want to know.

Now... if you have city water, you can probably just get the info from your supplier.
