Soft water See also: Water softening. Soft water is surface water that contains low concentrations of ions and in particular is low in ions of calcium and magnesium. Soft water naturally occurs where rainfall and the drainage basin of rivers are formed of hard, impervious and calcium poor rocks.ecause soft water has few calcium ions, there is no inhibition of the action of soaps and no soap scum is formed in normal washing. Similarly, soft water produces no calcium deposits in water heating systems. Water that is not soft is referred to as hard water.

Is soft water safe to drink? it is unlikely that a physician would discourage anyone from drinking softened water. Because water softeners are designed to address the problem of hard water and do not remove other water contaminants such as organic matter, many of our water softener customers also use a drinking water system.

- Water Softening. Soft water and hard water are common terms used in households across Pennsylvania. If you asked someone what these terms meant, you would probably get a definition based on how well the water cleans when used with detergents or soaps or what is left behind in tea kettles.ard Water/Soft Water. Whether a water supply is labelled “soft” or “hard” is dependent on the presence of two highly soluble minerals, calcium and magnesium. From a health standpoint, these minerals have no adverse effects and are, in fact, essential daily nutrients.

Water softener terminology explained 1 Soft water is less than 1 gpg, whereas hard water is about 7 gpg or higher. You can check your water for free with a quick test.  Parts per million: While less likely, you may also find hardness measured in parts per million (ppm) when shopping for a softener. One gpg is equivalent to 17.1 ppm.

Is Hard Water Causing Your Rash? Hard water is tap water that’s high in minerals such as calcium and magnesium. Hard water isn’t harmful, except the minerals prevent your soap from sudsing. Some people think that hard water is more likely to cause a rash than soft water. Take a recent patient of mine: he moved his family to San Diego from the East Coast (good move this winter, no). After they moved here, they noticed their skin became dry and itchy.

- The hardness of water may be expressed quantitatively in terms of parts per million (ppm) for calcium, ppm of calcium carbonate, and grains calcium carbonate per gallon of water. Based on grains of carbonate per gallon, water is classified as follows: Soft: 1 to 4 grains per gallon. Medium: 5 to 10 grains per gallon.

Salt-Free Water Softeners: Do They Work? Since the very definition of water softening requires that hard water minerals be REMOVED, and the salt-free process only ALTERS the minerals, allowing them to remain in the water, salt-free water softeners are not actually softening water – rather, they are for “water conditioning”.

Water Hardness and Alkalinity Hardness is caused by compounds of calcium and magnesium, and by a variety of other metals. General guidelines for classification of waters are: 0 to 60 mg/L (milligrams per liter) as calcium carbonate is classified as soft; 61 to 120 mg/L as moderately hard; 121 to 180 mg/L as hard; and more than 180 mg/L as very hard.
