Is my household at risk from heavy metals in El Paso County water? Government groundwater sampling shows selenium is commonly detected but below federal limits. Existing home equipment may not fully address spikes or gradual increases, so understanding test results and water conditions is crucial.
1. Reading a Certified Laboratory Test for Selenium in Household Water
The lab provides selenium concentration in micrograms per liter (ug/L)
This indicates the amount of selenium found but must be related carefully to actual safety standards. The laboratory report will also show detection limits and whether the measured levels are above or below them.
Concentrations reported are not violations but data points for decision-making
In El Paso County's aquifer 112HCBL, selenium was detected in 23 of 26 samples with values ranging from 0.05 to 11.7 ug/L. None exceeded federal thresholds, indicating no regulatory violation in these sampled wells. Your own well test is essential to confirm individual water conditions.
2. Steps to Rule Out Other Factors, from Cheapest to Laboratory Testing
Start with visual and taste indicators
Look for unusual changes in water color, taste, or staining that might hint at heavy metals presence, though these are not definitive.
Consider local plumbing and household equipment
Sometimes plumbing materials can affect water quality and mimic heavy metals issues, separate from the source water.
Then order a certified laboratory test specific to selenium and other heavy metals
This test confirms whether your water matches area levels or has differences needing specific attention.
3. The Role of Plumbing Material and Age, Separate from Source Water
Older or corroded plumbing can contribute contaminants
Heavy metals may leach from pipes or fixtures, especially if they contain certain alloys, unrelated to the aquifer’s natural selenium content.
Assess plumbing condition to distinguish source water issues from household system effects
Testing water both before and after household plumbing helps identify where metals arise.
4. Which Fixtures, Appliances, or Processes Are Affected First and Why
Appliances using hot water—like water heaters—can concentrate metals
Some metals become more soluble or mobilized at higher temperatures, impacting these points earlier.
Fixtures with aerators or filters may show early signs of buildup
Accumulation of metals might cause clogging or reduced flow first in these devices.
5. What the Measured Range Means Against the Federal Standard, and What It Does Not Mean
The federal standard for selenium is not exceeded in El Paso County sampling
Detected selenium in sampled wells ranges up to 11.7 ug/L, all below regulatory limits. This means no legal health-based violation was found in the area samples.
A detection is not a statement about individual safety
Your well or tap water requires specific testing to determine true concentration and any personal risk.
Given your current equipment cannot keep up with heavy metals concerns, consider the C-Series Heavy Metals Filter. This system ships ready to configure for effective selenium and other heavy metals treatment tailored to your household demand.
Next step: Order a certified laboratory test for selenium and other heavy metals on your household water. If results approach or exceed local aquifer levels—or your equipment struggles—upgrading to a targeted treatment like the C-Series is advisable.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2016-09-23. 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 Selenium in the 112HCBL aquifer (El Paso County): 26 results from 25 wells, median 2.6 ug/L, range 0.05-11.7 ug/L; none above any federal threshold
