If water at your home in San Juan County sometimes tastes or smells different or causes staining, you might suspect heavy metals are involved. While your current system works, it may not handle heavier metal loads during peak demand times. Here is a detailed checklist focused on public sampling data and household water quality management specifically for aquifer 110AVMB.
How Public-System Records Differ from Private-Well Testing
Public sampling measures broad area averages, not individual wells
The U.S. Geological Survey collected groundwater samples from eight wells in San Juan County’s aquifer 110AVMB between 2021 and 2025. None of the 104 results exceeded federal limits for barium—a common heavy metal. However, these data reflect median and range values across that region, not your household's specific well. Only a certified lab test on your own water can reveal its exact heavy metal levels.
Sampling depths provide context but not direct household data
The sampled wells were 35 to 68 feet deep, which may differ from your well’s depth and could affect the correlation between public figures and your specific water conditions.
How Treated Water Differs at the Tap After Heavy Metals Filtration
Reduction of barium and other heavy metals
Using the C-Series Heavy Metals Filter results in noticeably clearer water at your taps. This technology specifically targets dissolved metals like barium, reducing their concentration so they are less likely to cause taste, coloration, or buildup issues.
Consistent performance under varying demand
The system is designed to maintain heavy metals removal even when household water use increases, helping the water quality remain stable.
Maintenance Rhythm of the Documented Technology
Regular check and replacement schedule
The C-Series System ships ready to configure and requires periodic replacement of filter components according to usage and water quality, ensuring continual protection without unexpected degradation in performance.
Monitoring water quality trends
Observing any reappearing stains or changes in taste can indicate when maintenance or component renewal may be needed.
What a Certified Laboratory Test for This Constituent Reports and How to Read It
Barium concentration in micrograms per liter (ug/L)
Lab reports will show your household water’s barium level in ug/L, comparable to the U.S. Geological Survey’s area data ranging from 3.7 to 170 ug/L. These results are numerical measurements, not indications of safety or violation on their own.
Comparing test results to federal standards
Federal authorities set thresholds to ensure water safety; the regional data from San Juan County show none above these limits. Your test results can be interpreted similarly, with consultation if levels approach or exceed these numbers.
The Order in Which to Rule Things Out, from Cheapest Check to Laboratory Test
Visual and sensory inspection
Look for staining, discoloration, or unusual taste as initial clues.
Review existing water equipment status
Check if your current system is performing within recommended parameters or showing signs of strain.
Conduct a certified laboratory test
This is the definitive step to know your actual heavy metals concentration and to guide treatment decisions.
To resolve whether your household water requires enhanced treatment for heavy metals, order a certified laboratory analysis focusing on barium and other metals of concern. A result within federal limits similar to regional data may confirm current system adequacy; elevated levels would indicate the need for the C-Series Heavy Metals Filter.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2025-09-19. 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 Barium in the 110AVMB aquifer (San Juan County): 104 results from 8 wells, median 9.7 ug/L, range 3.7-170.0 ug/L; none above any federal threshold
