The MAX Orange Line will open on schedule on Saturday, Sept. 12, 2015, and while construction is 95 percent complete, the federal funding process continues through 2019.

The most common household form of water softeners are ion-exchanging resin devices. There are three main types of water softeners, categorized based on what salt they use: sodium, potassium, or hydrogen. These water softeners have a bed of resin that water is passed through. The resin is negatively-charged, and so binds to the positively charged metal ions in the hard water.
Introduction to Hard Water and Water Softeners. A water softener removes the calcium and magnesium ions that make water hard by replacing them with salt / sodium via ion exchange. Look for an NSF-certified water softener with a system monitor to indicate when salt is low to make sure you maintain optimum levels for soft water.
