Sample Size and Aquifer Data Reliability
The groundwater quality data for aquifer 310COCN in Coconino County is based on 28 total dissolved solids (TDS) measurements taken from two separate wells. These wells range in depth from 600 to 1150 feet and were sampled between July 2017 and May 2025. While this sample provides a useful overview of regional conditions, the limited number of wells and samples means this data represents general trends rather than precise conditions of any one residential well. Individual wells can vary significantly due to localized geology and other factors, so direct testing of your own water is needed for accurate assessment.
How the Autotrol Complete Well System Addresses Dissolved Solids
The principal challenge with elevated TDS is its impact on taste, staining, and water's corrosivity rather than a safety concern. The Autotrol Complete Well System uses advanced media technology capable of treating up to 32,000 grains, designed to reduce dissolved solids to improve water aesthetics and protect plumbing fixtures. By cycling through programmed regeneration, it controls the buildup of salts and minerals, helping maintain water quality consistent with household needs.
Influence of Sample and Well Depth on Expected Water Quality
The depth of tested wells in this aquifer contributes to the range of TDS detected. Deeper wells often encounter water with varying mineral content due to strata differences. Samples spanning depths from 600 to 1150 feet highlight this variability, which explains why TDS figures ranged from 0.37 to 839.0 tons per acre-foot in the USGS data. Shallow or deep wells in your area may experience different water quality profiles, emphasizing the importance of site-specific water analysis before choosing treatment equipment.
Recognizing Symptoms of Dissolved Solids Issues
Households experiencing elevated TDS might notice subtle effects such as unusual taste, slight staining on fixtures, or altered water texture. However, many symptoms commonly attributed to water quality issues arise from other causes unrelated to dissolved solids. For instance, cloudiness, odors, or visible colors usually indicate the presence of other constituents or microbial activity rather than TDS levels. Confirming the presence and impact of dissolved solids requires proper testing to avoid unnecessary treatment.
Distinguishing Public System Records from Private Well Testing
Government records for aquifer 310COCN provide data for regional water quality trends affecting public and private wells alike. However, public water system reports often have continuous monitoring and broader sampling, while private well testing is a one-time or periodic snapshot focused on a specific location. The data from USGS wells inform what might be expected in local groundwater but do not replace or substitute any well owner’s own water tests. Understanding both helps decide the extent and type of treatment necessary for your household.
Summary of Regional Water Data and Further Information
The USGS groundwater sampling from two wells and 28 tests within Coconino County’s aquifer 310COCN offers insight into the range of total dissolved solids residents may encounter. While a few results exceeded the secondary aesthetic standard of 500 mg/L, this is a guideline for taste and staining, not a health limit or violation. For any residential water, testing from your own source is essential to determine actual treatment needs. For households seeking reliable treatment capable of addressing dissolved solids, the Autotrol Complete Well System ships ready to configure and handles up to 32,000 grains, providing a robust solution aligned with these conditions.

Where this information comes from
Source: USGS groundwater sampling. Sampled 2025-05-16. 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 310COCN aquifer (Coconino County): 28 results from 2 wells, median 137.07 tons/ac ft, range 0.37-839.0 tons/ac ft; 5 above an AESTHETIC secondary standard only (secondary standard 500.0 mg/L (aesthetic)) - not a health finding
