Understanding 'Detected,' 'Median,' and 'Range' in Regional Water Sampling
The U.S. Geological Survey collected 42 total dissolved solids (TDS) results from 11 wells in Maricopa County’s aquifer 112BSFL between 2010 and 2018. Each result measures a specific sample from a well, representing water quality at that time and place. The median value of 249.5 milligrams per liter (mg/L) indicates the midpoint concentration among the samples, not the concentration in any single well. The range extends from 0.31 to 1800 mg/L, showing the variability between sampled wells from 120 to 635 feet deep. These figures characterize the broader regional aquifer quality but do not specify any individual residential well’s composition.
Routine Maintenance Expectations for Residential Complete Well Systems
The Autotrol Complete Well System ships ready to configure and is designed for residential water demands. Maintenance mainly consists of periodic checks aligned with water usage and quality changes. This system requires replenishing with salt or regenerant material based on the 32,000 grain capacity, a measure of its softening or conditioning capability. Regular observation ensures it is operating within recommended parameters, providing consistent treatment without the need for frequent technical intervention.
Significance of Sample Count and Well Depth in Regional Water Data
The data includes 42 samples from 11 wells, providing a snapshot of TDS conditions across a depth range of 120 to 635 feet in this aquifer. While this sample size offers valuable regional insight, it is limited in scope and cannot capture the full variability of individual wells. Due to geological differences and well construction, water quality can vary greatly even within the same aquifer area, emphasizing the need to test your own water directly.
Gathering Essential Information Before Consulting on Treatment Choices
Before seeking specific treatment advice, note down details about your well and water usage, including:
- Well depth and construction details
- Recent water quality test results, especially total dissolved solids and other key parameters
- Water demand patterns typical for your household
- Any noticeable water characteristics like taste or staining
Having this information ready helps clarify your treatment needs and supports more tailored recommendations.
A Logical Sequence for Water Quality Investigation
Start with the simplest checks moving toward detailed analysis:
- Visual and taste inspection for obvious issues
- Testing for total dissolved solids and other common constituents through a certified laboratory
- Confirming the condition of household plumbing, as it can impact perceived water quality
- Considering the local aquifer data as background context but not sole evidence for decisions
Summary of Regional Data and Next Steps
The USGS data for Maricopa County’s aquifer 112BSFL covers multiple wells and samples revealing a median TDS level of 249.5 mg/L and variability up to 1800 mg/L, all within a range of expected regional variation. These findings address aesthetic water quality factors rather than safety concerns. Testing your own water is essential to match treatment solutions to your household’s specific conditions. The Autotrol Complete Well System offers a 32,000 grain capacity approach to meet typical residential needs in this area.

Where this information comes from
Source: USGS groundwater sampling. Sampled 2018-05-02. 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 112BSFL aquifer (Maricopa County): 42 results from 11 wells, median 249.5 mg/L, range 0.31-1800.0 mg/L; 15 above an AESTHETIC secondary standard only (secondary standard 500.0 mg/L (aesthetic)) - not a health finding
