The softener may not be working right and adding sodium and chloride
to your water. Substitute potassium for sodium if you are using salt
substitute instead of softener salt (sodium chloride).
Yes road salting can cause high sodium, chlorides and TDS and all
three are corrosive to metals. So get tests for pH (yours is a bit
low), total hardness, TDS, chlorides, sodium, sulfates, iron, nitrate
and Coliform bacteria.
Your nitrate is somewhat high and that can be a health concern,
especially for a fetus and infants. Nitrate fluctuates seasonally with
precipitation levels and snow melt.
The Langelier Saturation Index (LSI) is not a good corrosivity test,
there are others that are much better but IMO none will benefit you
much in identifying what might be causing corrosion and we know that
high TDS, chloride and sodium will cause it.
