My test results finally came in:
I am starting to wonder if I should drain my EFM this summer and fill it with water from Lake Champlain!
How to get rid of hard water

Not horrible when laid side by side with my well water, but definitely in both the iron removal and softening requirement zone.
Lets see how my Ca and Mg predictor method works for it:
Total Hardness = 433 = ~2.5(Ca) + ~4.12(Mg)
70% of 433 = 303.1 = predicted hardness from Ca.
303.1/2.5 = 121.1 mg/L (ppm) of "predicted" calcium, vs 138 mg/L actual
30% of 433 = 129.9 = predicted hardness from Mg.
129.9/4.12 = 31.5 mg/L (ppm) of "predicted" magnesium, vs. 21 mg/L actual
Not bad for ballparking it from only the hardness reading. Got the calcium close, but the magnesium not so close.

As a check on Ward Labs:
Predicted Total Hardness = ~2.5(138.0) + ~4.12(21)
Predicted Total Hardness = 431.5 (vs 433 actual)
Predicted Total Hardness = ~2.5(138.0) + ~4.12(21)
Predicted Total Hardness = 431.5 (vs 433 actual)

Rob, did that Ward Labs tested sample come direct from the well, or from a tap pre but somewhat near the softener? The unusually high sodium and chloride ion counts suggest that there might have been a bit of back-flowing of water from the softener into the sample you sent off for testing. ???

I ran a hose from the pressure tank to the drain at full flow for 5 minutes, then collected the sample right from hose bib on the pressure tank. There is a check valve between my pressure tank and the treatment system, so I can't see how anything back flowed.lsayre wrote: ↑Tue.

I am wondering if it is due to road salt

It could be road salt, particularly if the well isn't real deep. Or it could just be inherent of the water table in your area. Generally people near salt water bodes have water that looks a lot like yours as to sodium and chloride.

Our well is about 250' deep. The levels of sodium and chloride seem to be "safe" based on what I found online (link below), but I am not sure how it compares to other wells in my area. I looked up the local municipal water report, but they don't have sodium and chloride listed.

At 250 ft. deep I'm back to speculating as to some degree of softener water contamination in the sample. Pull a well water sample from the nearest neighbor who has a hand pump on their (preferably similar depth) well and send it off to Ward Labs. Or pull the well cap off and send a weighted bottle down on a string.Rob R. wrote: ↑Tue. Feb. 16, 2021 12:00 pmOur well is about 250' deep.

Based upon some quick cation and anion balancing your 'straight' softened water will have a sodium level somewhere close to this:
Na = ~ 265 mg/L
The daily recommended sodium intake is on the order of 3,500 mg (albeit that most of us exceed this), or 2,500 mg if you are on a Dr. ordered sodium restricted diet. It is vitally needed by the body, so without consuming it daily at somewhere likely right near the restricted level no less than death assuredly follows. So at 265 mg/L you could hit the restricted intake level on tap water alone if you drink 2,500/265 = 9.4 Liters (10 quarts) of your well water daily (which sounds along the lines of something Tom Brady might do). If you haven't already, you might want to consider adding an RO (reversed osmosis) unit under your kitchen sink. And drink/cook only from the RO tap.
I once heard that heart attacks are more common among those so highly restricting their sodium intake as to not be getting anywhere close to 2,500 mg/day than they are among those routinely exceeding 3,500 mg/ day (which also potentially causes serious problems). But this might merely be hearsay, so.... (verify, verify, verify).

I am not hung up on the sodium results - for now I am more interested in making sure my softener is programmed correctly, and that my birm filter is appropriate for treating the iron and sulfur in my water.
Based on what I see in the results, my birm filter should be fine. I brought the control head to my local water guy to see what was wrong with it - and he said the piston and seals were scored due to sand. He recommended a 5 micron sediment filter prior to the birm filter to prevent reoccurrence.
