Overview of Groundwater from Aquifer 374ELBK in Jefferson County
The groundwater supplying many residential wells in Jefferson County is drawn from aquifer 374ELBK. Well water from this aquifer typically comes from depths between 126 and 232 feet. Water travels through various geological layers before reaching household taps, carrying dissolved minerals and compounds characteristic of the local environment.
Additional Questions Commercial or Industrial Users Consider
While households generally focus on the immediate aesthetic and operational effects of their well water, commercial and industrial operators often require a broader range of data. They inquire about parameters such as total dissolved solids variability, treatment system capacity to handle fluctuating demand, and compliance with secondary standards affecting machinery and product quality. Households can benefit from understanding these concerns to better frame their own water management needs.
Seasonal and Multi-Year Variation in Jefferson County Water Quality
Analysis of samples taken between June 25, 2014, and October 21, 2024, reveals that total dissolved solids (TDS) levels in this aquifer fluctuate over time. Measured values ranged from as low as 0.42 mg/L to as high as 833.0 mg/L. This variation may reflect natural shifts in groundwater chemistry driven by seasonal recharge, weather patterns, and geological influences. Understanding these trends can help homeowners anticipate changes in water taste, staining potential, and overall quality.
Sample Size, Well Numbers, and Statistical Significance
The data set comprises 12 samples collected from 3 separate wells in the area. While these samples provide useful insight into water quality trends for aquifer 374ELBK, the limited number of wells and samples means results represent localized snapshots rather than exhaustive coverage. Households should consider testing their individual well water to determine specific conditions, as area-wide data cannot definitively characterize every private well.
Comparing Jefferson County Data with Neighboring Areas
When comparing Jefferson County's groundwater data to nearby counties, it is important to note differences in geology, land use, and water table depths. These factors influence total dissolved solids and other water characteristics. Area-specific data like that from aquifer 374ELBK should not be directly applied to neighboring regions without contextual understanding, as variations can be significant and may affect treatment needs.
Assessing Treatment System Capacity for Household Demand
Residential households must consider their daily water consumption when selecting water treatment solutions. The Autotrol Complete Well System offers a grain capacity of 32,000 grains, which addresses a broad range of contaminant loads typical in well water from Jefferson County. Evaluating household water use alongside this capacity helps ensure the system provides effective treatment and longevity before regeneration or maintenance is needed.
In summary, government-recorded water quality data for Jefferson County's aquifer 374ELBK reflects median total dissolved solids of 346.0 mg/L, with values spanning a wide range across sampled wells over a ten-year period. These figures describe the general conditions of groundwater in the area but do not specify individual well quality. The Autotrol Complete Well System ships ready to configure and is designed to manage the typical dissolved solids concentrations found here. For precise water characteristics, household well owners should conduct their own testing. More detailed information is available through the U.S. Geological Survey groundwater monitoring site for this location.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2024-10-21. 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 374ELBK aquifer (Jefferson County): 12 results from 3 wells, median 346.0 mg/L, range 0.42-833.0 mg/L; 4 above an AESTHETIC secondary standard only (secondary standard 500.0 mg/L (aesthetic)) - not a health finding
