1. What to Record Before Seeking Treatment Guidance
This week, your key task is to gather detailed information about your well water conditions before deciding on treatment options. Write down the depth of your well, recent water clarity or taste changes, and any relevant household water issues like staining or scaling. Knowing if your well taps into the local aquifer 111ALVM will also help contextualize any lab results you might obtain later.
2. Influence of Sample and Well Depth on Water Quality Expectations
Government groundwater sampling in Linn County’s 111ALVM aquifer involved wells ranging from 18 to 74 feet deep. Since the water quality can vary significantly depending on well depth, your own well's depth may influence total dissolved solids (TDS) concentrations and other characteristics. Shallower wells might show greater TDS fluctuation, whereas deeper wells sometimes present more stable readings. However, these area-wide samples reflect regional trends and do not predict your specific well's conditions precisely.
3. Recognizing Household Symptoms Related to Total Dissolved Solids
TDS encompasses minerals, salts, and organic matter dissolved in water. Symptoms like unusual taste, mineral buildup on fixtures, or staining can be linked to elevated TDS levels. Yet, these signs are not definitive without testing. Not all water hardness, staining, or taste changes indicate TDS concerns. Other factors such as plumbing materials or well maintenance routines may cause similar household water issues.
4. Differentiating TDS Issues from Other Common Water Problems
It’s important to distinguish between TDS-related symptoms and problems from separate sources like iron or microbial contaminants. While iron imparts reddish staining and can alter taste, TDS primarily affects water’s general mineral balance and conductive properties. Misidentifying the cause can lead to ineffective treatment. Detailed testing clarifies these differences, preventing unnecessary or incorrect system purchases.
5. Example Interpretation of Linn County Aquifer TDS Data
The U.S. Geological Survey sampled 16 wells across Linn County’s aquifer 111ALVM, collecting 732 total dissolved solids results between March 2010 and June 2026. The median TDS concentration recorded was 298 mg/L, with most results detected but only 8 exceeding the Secondary Standard aesthetic threshold of 500 mg/L. This threshold relates solely to taste and staining potential, not health risk or regulatory violation. The wide range from 0.29 to 989 mg/L reveals variability but cannot be applied directly to your specific well without a test.
6. Understanding Certified Laboratory Reports for Total Dissolved Solids
A certified lab test for TDS will quantify the dissolved mineral content in your water sample, typically reported in milligrams per liter (mg/L). The report will confirm presence and concentration, enabling you to compare your water's TDS level with regional data and secondary aesthetic guidelines. It is critical to use a reputable lab to ensure accurate results that inform your treatment choices appropriately.
Closing Recommendation: To resolve uncertainty about your well's total dissolved solids, order a certified laboratory test specifically measuring TDS from a representative water sample of your household supply. A clear result will determine if the Autotrol Complete Well System with its 32,000-grain capacity aligns with your treatment needs for managing dissolved solids efficiently.

On record: U.S. Geological Survey sampling of Total dissolved solids in the 111ALVM aquifer (Linn County): 732 results from 16 wells, median 298.0 mg/L, range 0.29-989.0 mg/L; 8 above an AESTHETIC secondary standard only (secondary standard 500.0 mg/L (aesthetic)) - not a health finding
