What Additional Questions Do Commercial or Industrial Operators Add That a Household Does Not
Commercial and industrial water users often need to understand water quality in terms of process impact, regulatory compliance, and throughput capacity. Unlike a household relying on water for drinking, cooking, and bathing, these operators ask about variations across multiple supply points, the consistency of constituent concentrations under different pumping regimes, and the influence of water chemistry on equipment longevity. For a household in Navajo County, these concerns are simplified but can still inform choices about treatment technology capacity and maintenance.
What 'Detected', 'Median' and 'Range' Mean in the Sampling Record on This Page
The U.S. Geological Survey collected 120 total dissolved solids (TDS) measurements from 14 wells within the Navajo County aquifer 220NAVJ over nearly a decade. Every single sample showed TDS detected — meaning measurable amounts were present. The median value, 143.5 mg/L, represents the middle point where half the samples fall below and half above. However, the range is broad, from 0.13 mg/L to 914.0 mg/L, indicating significant variation between wells and times. A detection does not imply any health concern but simply confirms TDS presence, which can affect taste or cause staining if high.
How Many Samples and Wells Stand Behind the Figures, and What a Small Sample Means
The 120 samples span 14 wells, with depths between 554 and 3737 feet. This is a robust data set for the Navajo County area, giving a reasonable overview of the aquifer 220NAVJ water quality. However, no single household well is guaranteed to reflect these exact values; local geological and hydrological factors can cause differences. Small sample sizes, if present, would reduce confidence in conclusions, but here the volume supports a representative understanding of regional TDS levels.
Maintenance Rhythm of the Documented Technology in Plain Terms
The Autotrol Complete Well System is designed to manage the kinds of dissolved solids observed in Navajo County. Typically, this system supports up to 32,000 grains of treatment capacity, enough for a mid-sized household's daily water needs. Maintenance involves routine checks of system operation, periodic media replacement when capacity nears exhaustion, and ensuring valves and controls remain responsive. The system ships ready to configure, allowing a homeowner familiar with water treatment setups to adapt it to their plumbing. Scheduled upkeep maintains performance and water quality over time.
What the Reader Should Write Down Before Asking Anyone for Treatment Advice
Before consulting a water treatment expert or supplier, the reader should compile these points:
- Results from an up-to-date laboratory test of their own well water, including total dissolved solids concentration
- Depth and type of their well to compare against regional sample ranges
- Daily household water usage volume to determine treatment system sizing
- Any noticeable water quality issues such as taste, staining, or scaling
- Past water treatment equipment details, if applicable, and any maintenance records
This information helps tailor advice specifically to the household’s circumstances rather than relying solely on regional data.
What the Reader Should NOT Conclude From Area Data
The regional sampling data from USGS provides a helpful background on typical total dissolved solids levels in Navajo County. However, it must not be taken as a definitive statement about any individual well's water quality. Detection of TDS is expected but not synonymous with a problem. The few samples exceeding the secondary standard of 500 mg/L concern taste and aesthetics and do not indicate an unsafe condition. Personal water testing remains essential to identify actual household water characteristics and needs. The Autotrol Complete Well System can then be matched appropriately to address those specific conditions.

On record: U.S. Geological Survey sampling of Total dissolved solids in the 220NAVJ aquifer (Navajo County): 120 results from 14 wells, median 143.5 mg/L, range 0.13-914.0 mg/L; 11 above an AESTHETIC secondary standard only (secondary standard 500.0 mg/L (aesthetic)) - not a health finding
