Water hardness in Arkansas, 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 Southern U.S., Arkansas’s water hardness levels reflect the geological diversity within the state.
Across Arkansas, water hardness can range from moderately soft to very hard. For example, regions with limestone bedrock, such as parts of the Ozark Mountains in the northern part of the state, often have harder water due to the high mineral content. In contrast, areas with more sandstone or shale bedrock, such as the Mississippi Alluvial Plain in eastern Arkansas, may experience softer water.
The variation in water hardness throughout Arkansas 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 Arkansas. Among the cities for which data is reported, the highest water hardness levels are recorded in Lowell and Fort Smith, with hardness levels of 73 ppm (4.3 gpg) and 26.5 ppm (1.5 gpg), respectively.

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.
