Hardness and More

Two thirds of the water on earth is groundwater. As it
travels through rock and soil it picks up particles of
calcium, magnesium, iron, lead, and other minerals. For
85% of the country, that translates into "hard water".
"Hardness" refers to the amount of calcium and
magnesium in the water and is measured in grains per
gallon (gpg). The following guide defines your water's
hardness based on two different measurements. Our test
determines the grains of hardness that can easily be
converted into the ppm.

Most of the problems associated with hard water are
economical in nature. Hardness causes unsightly soap
scum on fixtures, water spots on glasses and whitish scale
deposits in your tubs and showers. Hard water means you
use more soap and cleaning agents because they first
have to "clean" the water before they clean anything else.
