Local Aquifer Characteristics and Water Delivery to Homes
Randolph County in Arkansas draws well water primarily from aquifer 110ALVM. Water here is accessed through wells drilled between 63 and 128 feet deep, tapping into groundwater that supplies many households. This aquifer’s water quality influences both the taste and interaction of water with household plumbing and appliances.
Seasonal and Multi-Year Variation in Acidity and Hardness
The U.S. Geological Survey sampled groundwater from 9 wells in Randolph County’s 110ALVM aquifer over an eight-year period from June 2010 through October 2018. Across 15 measurements, the pH ranged from 6.7 to 8.4 standard units, with a median of 7.2. This range demonstrates natural variation over time, influenced by factors such as rainfall patterns, geological shifts, and aquifer recharge status. Notably, none of the samples fell below the EPA secondary standard minimum pH of 6.5, indicating the water typically remains within an acceptable aesthetic and plumbing corrosion range.
Additional Questions Commercial Operators Consider Beyond Household Concerns
While households focus on domestic-level effects of acid and hardness, commercial users often consider additional factors such as scale accumulation rates in equipment, water volume demands, and impacts on industrial processes. For residential users, questions tend to center on faucet staining, soap efficiency, and appliance longevity rather than broader operational impacts. Understanding these distinct priorities helps clarify the best treatment approach.
Interpreting 'Detected,' 'Median,' and 'Range' in Water Sampling Data
The terms detected, median, and range represent specific data points in groundwater quality records. 'Detected' means a constituent was measured at or above the limit of instrument sensitivity. 'Median' is the middle value of all samples, providing an indicator of typical conditions. 'Range' shows the variability between the lowest and highest results recorded. None of these terms imply a violation of water quality standards, only measured values within the sampled area. Household testing is necessary to establish individual well water characteristics.
Distinctions Between Acid and Hardness and Other Water Quality Issues
Acid in water refers to lower pH levels that can increase metal dissolution and plumbing stress, whereas hardness relates to dissolved minerals like calcium and magnesium that cause scale build-up. These are separate concerns from contaminants such as iron or sediment, which produce visible staining or cloudiness. Effective treatment plans address the specific chemistry of acid and hardness without conflating other water factors.
Maintenance Schedule for the Fleck Acidic Water + Hard Water (Well) System
The Fleck System designed for acidic and hard water operates with a grain capacity of 32,000, tailored to typical household usage. Maintenance involves periodic regeneration cycles to restore media effectiveness and occasional media replacement depending on water usage and hardness levels. This system ships ready to configure to fit standard household plumbing setups, allowing users to manage water quality consistently over time.
Consequences of Leaving Acid and Hardness Untreated Long-Term
Without treatment, acidic water can gradually affect plumbing materials, potentially leading to increased wear or leaks over many years. Hardness can cause scale deposits inside pipes and on fixtures, reducing water flow and appliance efficiency. While these effects develop slowly, addressing acid and hardness promptly helps preserve plumbing integrity and appliance lifespan.
What Not to Conclude From the Randolph County Aquifer Data
The groundwater sampling data from aquifer 110ALVM offers a regional perspective and does not predict the exact quality of water from any individual well. The fact that all tested samples remained above a pH of 6.5 means the water generally meets EPA recommendations concerning pH aesthetics and corrosion. However, this does not guarantee that every household well water matches these parameters; personal water testing is required for confirmation.

On record: U.S. Geological Survey sampling of pH in the 110ALVM aquifer (Randolph County): 15 results from 9 wells, median 7.2 standard units, range 6.7-8.4 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 0 of 15 sampled results fell below 6.5
