This report just came in from LWS in the mail the other day. If you didn't get one or tossed it thinking it was junk mail, have another look. Here's some data for you water treaters:
Water Quality Parameters (12/10/2009)pH: 7.71
Total Alkalinity (CaCO3): 160 ppm
Total Hardness (CaCO3): 200 ppm
(12 grains per gallon)
Total Dissolved Solids: 336 ppm
Calcium: 54.4 ppm
Chloride: 20.5 ppm
Iron: < 0.05 ppm
Manganese: 1.04 ppb
Sodium: 30.6 ppm
Sulfate: 77 ppm
"Lincoln's water is moderately hard. Alkalinity, pH and hardness are important if considering a water softener."
