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.
You have three choices when it comes to water softener salt. There is rock salt, evaporated salt or solar salt. Rock salt is mined from salt deposits under the ground and is used in its raw form, which contains traces of other materials besides salt, some of which are not dissolved in water.
