Water Hardness in Colorado

Water Hardness in Colorado
Posted on 02/11/2019

Hard water residue on dishes, shower heads, dishwashers, water bowls and other items may be more noticeable this time of year. This is a result of naturally occurring calcium in Colorado’s groundwater.

Colorado, like many other surrounding states, has a higher concentration of minerals in rock and soil. Known as the “universal solvent,” water dissolves these minerals as it moves through the ground during spring, summer and fall when water demand is higher and water is moving at a more rapid pace. During winter months, calcium may become more noticeable because water moves slower through the ground or sits in reservoirs longer, allowing it to absorb more minerals.

Though calcium can leave residue on dishes and appliances, it’s harmless. To ease the impacts this may have on your household, we recommend using a rinse aid in your dishwasher, or vinegar to de-scale the deposits in smaller appliances like coffee makers. Other options include a water filter pitcher or a home water filtration system; just remember, water filter systems must be serviced routinely to maintain their effectiveness.
