What is hard water


Water is just hydrogen and oxygen molecules when it drops from clouds onto our heads, streams, lakes, rivers, oceans or simply onto the ground. Once water hits the ground it begins to pick up parts of minerals and the more minerals it contains the ‘harder’ it becomes.

Hard water is a very common problem, affecting water in more than 85% of the country. It is a result of the dissolved minerals calcium, magnesium and manganese. With an increase in these minerals many problems occur such as, soap scum in sinks and bathtubs, bathtub rings, spots on dishes or shower doors, reduced foaming and cleaning abilities of soaps and detergents, dingy and yellowed clothes with soapy residues that require extra rinsing to remove, clogged pipes from buildup of minerals, increased water heating costs from buildup of minerals, reducing efficiency of water heaters and possible skin infections from bacteria trapped in pores underneath soap scum. While these are all unpleasant effects hard water is not a hazard to human health and can be treated.

If you suspect that you have hard water it can be tested. When results are returned to you and your water is found to be hard there are a few options available to you. The most common way to soften water is through an ion exchange water softener. This system works by exchanging positively charged hardness minerals with positively charged softness minerals on a resin surface that is regenerated. This exchange of minerals softens the water and can extend the life of plumbing systems since there is reduced clogging in the pipes.

Many of us enjoy hard water particularly for drinking because it tends to taste better. Yet hard water for washing can leave mineral deposits on dishes, clothing and hair. You may not feel as clean when you shower in it and over time your clothing can become dingy along with your hair lackluster and dull if it’s repeatedly washed in hard water.
