Do you know if your water comes from the Potomac? I was told that my water here in Sterling did. When I talked with somebody from Loudoun Water, it was not clear if my area actually got water from Fairfax, or if the lady was saying that they both got water from the Potomac and treated it the same. In any case, water in this area is from surface water sources.

Below is my report from late Feb 2019. It is in the same ball park as yours. I suspect my Chloride (and Sodium?) level was elevated due to winter salt run off. Based off info from other reports, I tweaked some of the values that I use in BeerSmith for my water profile to values that I suspect are closer to the average values. Those are shown below in brackets.

Note that with a Ward Labs report, you have to multiply the Sulfate, S04-S value by 3 to get the Sulfate value (instead of the reported “as Sulfur”) value.
