very hard; 20+ on the hardness scale (no pun intended). I thought that my dishwasher wasn't working because of the white stuff all over my dishes. I had someone look at it and it's working fine... it's the hard water. Duh! No wonder my 1 1/2 year old water heater has already had a problem.
I used that mail in testing thingy that Sears offers (already knowing that I MUST have very hard water). It came back with iron, etc. normal, but the calcium, etc. (hardness) off the scale.
Now... if I could just feel comfortable about paying 2500.00 for a water softener when I see them in Home Depot for 499.00.
