If you rely on public water records instead of testing your private well, what can you really know?
Many homeowners interpret water quality issues by looking at regional or municipal water system data. However, these public system records reflect broad area conditions and cannot pinpoint your specific well's water quality. They show what has been sampled from multiple wells over time within Pottawatomie County’s aquifer 310WLNG but cannot replace a direct water test from your own well. A private well’s characteristics can vary due to depth, location, and local geological factors, so only a current test of your own water can establish your water’s exact total dissolved solids (TDS) level and related traits.
If you compare Pottawatomie County’s groundwater with that of neighboring counties, what should you consider?
Water quality data from nearby counties may have different ranges or medians for TDS, but these variations are influenced by geology and sampling breadth. Pottawatomie County’s aquifer data show a median TDS of 249 mg/L, a range from 0.11 to 903 mg/L, and a few results above the 500 mg/L secondary aesthetic threshold that can affect taste and staining. While this provides context, it does not mean your well water matches either county’s exact profile. Regional comparisons offer general insight but cannot determine individual well conditions.
What does the number and depth of sampled wells tell you about the reliability of this data?
The US Geological Survey sampled 59 results from 24 separate wells dug between 80 and 320 feet deep from 2011 to 2013. This sample size provides a reasonable overview of groundwater conditions in the aquifer but remains limited compared to the number of private wells in Pottawatomie County. A small sample size means variations are possible, and your well water could fall anywhere in the recorded range or outside it. This underlines why personal water testing is essential.
Which parts of your household are affected first by elevated total dissolved solids?
TDS mainly influences the taste, odor, and appearance of water rather than posing a direct health risk. Household fixtures such as faucets, showerheads, and appliances like dishwashers and washing machines may experience mineral buildup or staining when TDS exceeds aesthetic thresholds. Hot water heaters and plumbing can also accumulate scale over time, reducing efficiency. Knowing your well’s specific TDS level helps identify whether these issues could arise.
Why do aesthetic secondary standards for TDS differ from health-based limits?
Total dissolved solids have a secondary standard of 500 mg/L set for aesthetic considerations like taste and staining. This is not a health-based limit, does not signal a violation, and does not mean water is unsafe at or above this level. Instead, it helps guide homeowners on potential water quality effects requiring treatment for comfort and appliance longevity. Understanding this distinction prevents unnecessary worry about safety when only aesthetic impacts are present.
What household symptoms suggest the need for water treatment for TDS?
- Noticeable changes in water taste or smell
- Staining on sinks, toilets, or laundry
- Frequent scale buildup on plumbing fixtures
- Reduced appliance performance due to mineral deposits
Symptoms not directly related to TDS, such as cloudiness or discoloration caused by sediment or organic materials, require different investigation and treatment approaches.
In summary, government sampling in Pottawatomie County’s aquifer 310WLNG from multiple wells between 80 and 320 feet deep shows a median total dissolved solids concentration of 249 mg/L, with some results above the 500 mg/L aesthetic threshold but no safety violations. This data provides a regional profile but cannot substitute for testing your household well water to determine exact conditions. For addressing elevated dissolved solids in a complete well water system, the Autotrol Complete Well System ships ready to configure and offers a proven solution with a grain capacity of 32,000 to improve water quality for your home.

Where this information comes from
Source: USGS groundwater sampling. Sampled 2013-05-01. 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 Total dissolved solids in the 310WLNG aquifer (Pottawatomie County): 59 results from 24 wells, median 249.0 mg/L, range 0.11-903.0 mg/L; 6 above an AESTHETIC secondary standard only (secondary standard 500.0 mg/L (aesthetic)) - not a health finding
