The water in St. Charles

Here's what's really in your St. Charles water

Before you spend a dime, it helps to know what you're actually dealing with.

Your testFree, in-home

St. Charles city water comes off the Missouri River and runs some of the hardest water in the region - typically 18-22 grains per gallon, plus the chlorine used to disinfect it. Whole-home carbon filtration takes out the chlorine and taste; a reverse-osmosis system under the sink gives you bottled-quality drinking water on tap.
