Serving Homes Across Greater St. Louis
Water quality varies by source and by county. Pick your area below to see what’s typical in your water — and what we usually recommend.
St. Louis City & County, MO
St. Louis, Clayton, Kirkwood, Webster Groves, Florissant, Chesterfield
The St. Louis core draws from the Missouri and Mississippi Rivers, treated by some of the largest municipal plants in the region — effective, but it still leaves noticeable hardness and a chlorine edge at the tap.
