Government sampling of groundwater from aquifer 112PLSC in Randolph County, IN, shows a pH range between 7.0 and 7.9 standard units with a median of 7.25, based on 14 samples from three wells collected between 2014 and 2025. This range is within the EPA secondary standard for pH (6.5–8.5), a guideline aimed at controlling water's taste, staining, and corrosivity rather than health effects.
If acid and hardness in water remain untreated for years
When water containing acid and hardness is not treated over a long period, household systems may experience gradual damage. Acidic water can slowly wear away plumbing materials and fixtures, while hardness minerals like calcium and magnesium can build up inside pipes and appliances, reducing their efficiency and lifespan. The combination may lead to mineral deposits, scaling, and possible discoloration or spotting on dishware and fixtures.
If you consider the median and range in Randolph County’s water data
The median pH of 7.25 in the sampled wells suggests that water in this area is neither strongly acidic nor alkaline but generally neutral to mildly alkaline. The range from 7.0 to 7.9 means individual water samples show moderate variation within the typical pH limits for aesthetic quality. This helps set expectations that while water acidity problems are uncommon here per the data, hardness remains a relevant issue to address.
If your well depth or water source differs from the sampled wells
The sampled wells ranged from 18 to 95 feet deep, which can affect the water chemistry encountered. Deeper wells may access groundwater with different mineral profiles and pH characteristics. Because your own well could tap a different depth or local condition than the sampled wells, the area data serves as an informative guide rather than a substitute for specific testing of your water.
If certain fixtures or appliances show early signs of acid and hardness effects
- Water-using appliances such as water heaters and dishwashers may accumulate scale buildup faster or experience diminished heating efficiency.
- Faucets, showerheads, and sinks may develop spotting or mineral deposits that reduce performance or appearance.
- Water pipes, particularly if made of metals sensitive to acid, might show signs of wear over time.
Identifying these early signs can guide the timing of treatment measures.
If you consider ongoing maintenance for a Fleck Acidic Water + Hard Water (Well) System
This system is designed to handle acid and hardness problems by conditioning your water with a grain capacity of 32,000, which supports sustained performance over extended usage. Regular maintenance involves replenishing the system’s media or salt supply and monitoring water quality to keep treatment effective. Because the system ships ready to configure, users can manage its operation and upkeep without reliance on external services.
To confirm whether your home water needs this type of treatment, the single test to order is a comprehensive water analysis that includes pH along with hardness minerals. A report showing pH near the local median and measurable hardness supports the usefulness of a Fleck Acidic Water + Hard Water (Well) System as an effective solution to restore water quality after equipment failure.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2025-09-04. These figures describe groundwater sampled in this area. They are not a test of any individual private well - only a test of that well can establish its own water.
On record: U.S. Geological Survey sampling of pH in the 112PLSC aquifer (Randolph County): 14 results from 3 wells, median 7.25 standard units, range 7.0-7.9 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 0 of 14 sampled results fell below 6.5
