Government groundwater sampling in Massac County’s aquifer 330MSSP found total dissolved solids (TDS) levels ranging from 0.39 to 301.0 mg/L with a median of 285.0 mg/L based on three samples from a well about 240 feet deep taken on August 5, 2019. None of these results exceed federal thresholds.
Myth: High TDS Means Your Well Is the Same as the Sampled Wells
The Massac County data represent measurements from selected wells in the aquifer, not your individual well. These figures help characterize regional water quality but do not determine your specific well’s water chemistry. To know your water’s TDS, a direct test of your well is necessary.
Myth: Exceeding a Range Value or Secondary Standard Means a Health Risk
The federal standards for TDS are largely aesthetic and relate to taste, staining, and corrosivity; they are not health-based limits. The sampled range in Massac County stays below all federal thresholds, indicating no health-based violation. A higher TDS reading does not automatically indicate unsafe water.
Myth: Water Quality Is Constant Throughout the Year
The TDS samples are from a single date, meaning seasonal or multi-year variations are not represented here. Such variations can occur due to factors like rainfall, aquifer recharge, or water use patterns. Understanding your well’s water quality over time requires periodic testing.
Myth: A Complete Well System Requires Frequent or Complex Upkeep
The documented Autotrol Complete Well System ships ready to configure for home use and offers a grain capacity of 32,000. This capacity helps address the TDS range found in Massac County. The system’s maintenance rhythm is straightforward, designed to match household demands without frequent intervention.
Myth: All Household Fixtures and Appliances Are Equally Affected by Water Quality
Water with elevated TDS or related constituents typically shows effects first in appliances and fixtures that use water intensively, such as water heaters, dishwashers, and faucets. These are more sensitive to staining or buildup, making them key indicators for treatment efficacy.
Myth: Water Quality at One Depth or Source Applies to All Wells
The Massac County samples came from wells around 240 feet deep. Wells that are shallower or tap different parts of the aquifer may exhibit different water characteristics. The source type and depth influence water quality expectations and treatment needs.
In summary, the regional data for Massac County’s aquifer 330MSSP provide useful context but should not be used to conclude specific conditions at your residence. Testing your own well water is essential before deciding on the treatment capacity needed. The Autotrol Complete Well System offers a documented solution with a substantial grain capacity to manage typical TDS levels in this region, making it a reliable choice for sizing a complete well water treatment setup.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2019-08-05. 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.
