How to test a well in Idaho.

What this means at home

Drink it as-is?
Test first. This is not a test of your well. Nearby samples say what to look for.
Filter drinking water only?
After you have a lab result. Buy a point-of-use filter certified for what your test flags, not for this estimate.
Soften the whole house?
Not needed. 4.5 grains per gallon is moderately hard. A softener is optional below 7 gpg. Hardness is not a health issue.
Test first?
Yes. A mail-in lab test is the only way to know what is in this well. Start with the kit above.

Hardness

Nearby samples run about 4.5 grains per gallon (gpg) (moderately hard), confidence grade B. That is an estimate, not a result from your well. Hardness is not a federal health violation.
