Water hardness in Wyoming, characterized by the amount of dissolved minerals such as calcium and magnesium, can significantly differ among various cities across the state due to its varied geological landscapes. Situated in the Western U.S., Wyoming’s water hardness levels reflect the geological diversity within the state.
Across Wyoming, water hardness can range from moderately soft to very hard, depending on the geological makeup of the area and the source of the water supply. For example, regions with limestone bedrock, such as the Bighorn Basin and parts of western Wyoming, often have harder water due to the high mineral content. In contrast, areas with more sandstone or shale bedrock, such as the Powder River Basin, Green River Basin, Wind River Basin, and Washakie Basin, may experience softer water.
The variation in water hardness throughout Wyoming influences not only the taste and aesthetics of the water but also the efficiency of soaps and detergents, plumbing maintenance, and the lifespan of appliances that utilize water. Given the state’s geological diversity, water hardness is not uniform, highlighting the need for localized water treatment solutions and ongoing monitoring of water quality.
In the provided data, the water hardness levels show substantial variations across different cities in Wyoming. Among the cities for which data is reported, the highest water hardness levels are recorded in Lovell and Byron, both with a hardness of 68.0 ppm, 4.0 gpg. Conversely, the city with the lowest recorded water hardness level is Gillette, reporting a hardness of 26.0 ppm, 1.5 gpg.

Hard water can cause issues such as mineral buildup in plumbing and appliances, reduce the efficacy of soaps and detergents, and affect the taste of the water. A tried and true solution is the use of a water softener. A water softener, like the ones from DROP, could be a worthwhile investment.
These devices work by replacing the calcium and magnesium ions that cause hardness with sodium ions, resulting in softer water. With innovative features, easy installation, and efficient operation, DROP smart water softeners provide a solution to hard water issues, extending the lifespan of appliances, improving water taste, enhancing soap effectiveness, reducing scale build-up, and increasing the overall water efficiency in your home.
