In my water report, attached, there is a relatively wide range of values across samples. For example, in one sample hardness is 52 mg/L but in another it's 98. Other key minerals show similar variability (as expected this is correlated, i.e. if one mineral is present in higher concentrations, all of them are - though there is never any chloride or sulfate detected). These wells are all merged together into my water supply. What's the best way to handle this: should I average all the results, or take one or the other extreme? Any other comments on my water? I haven't done a full analysis yet, but am I correct in thinking that my water is ranges from moderately soft to neutral? I started analyzing it because I wasn't happy with the quality of bitterness I was getting and because I'm getting poor mash efficiency (though I suspect that's due to bad MLT design).
