What does a nitrate test report show for water in El Paso County?

A laboratory report for nitrate in water lists the concentration in milligrams per liter (mg/L). For El Paso County aquifer 111ALFP, U.S. Geological Survey sampling from 10 wells between 2010 and 2024 shows nitrate detected in every sample, with a median of 7.56 mg/L and a range from 0.847 to 48.4 mg/L. These results come from wells that were 42 to 120 feet deep. These values reflect groundwater quality in the area, not a specific household's water.

Which household fixtures or processes are affected first by nitrate?

Nitrate itself typically does not cause immediate taste or staining issues in household water but is primarily a health concern when ingested, especially for infants and pregnant women. Appliances like reverse osmosis systems or water coolers that rely on water purity might show effects if nitrate is elevated, but the main concern is safe drinking water. Regular kitchen taps and water used for cooking are the primary points where nitrate levels matter most.

How can I compare El Paso County's nitrate data with nearby counties without misinterpreting it?

When comparing nitrate levels in El Paso County to neighboring areas, keep in mind that sample sizes, well depths, and local land use vary. El Paso County's data comes from 438 samples in regional wells, while adjacent counties might have different sampling scopes or timeframes. Differences in median and maximum concentrations do not directly translate to individual household water quality because each well can vary significantly. Use these comparisons only as a broad overview of regional groundwater trends instead of a direct measure of your water's condition.

How does a Pentair Nitrate & Nitrite (Well) Filter system address nitrate in water?

This treatment technology is designed specifically for reducing nitrate and nitrite from well water. It uses a filtration process engineered to remove these contaminants before water reaches household taps. Once configured, this system can help households manage nitrate levels effectively, enhancing water safety for consumption. It ships ready to configure, allowing users to set it up as part of their water treatment approach without the need for additional services.

What does the nitrate range measured in El Paso County tell us about federal standards and health concerns?

The federal Maximum Contaminant Level (MCL) for nitrate is 10 mg/L, a health-based threshold to protect sensitive populations. In El Paso County’s aquifer 111ALFP, 188 out of 438 samples exceeded this MCL, signaling that some wells have nitrate above recommended levels. However, this does not automatically mean all wells or household water supplies exceed the limit, nor does detection mean water is unsafe. Testing your own water is the only way to determine your specific nitrate concentration.

What household symptoms or issues might suggest nitrate presence in well water?

Nitrate itself does not cause taste, odor, or visible water discoloration. Health symptoms related to elevated nitrate are primarily from consumption—for example, methemoglobinemia (“blue baby syndrome”) in infants. Other household water uses such as cleaning or watering plants are less immediately affected. If you suspect nitrate issues, the only way to confirm is through a comprehensive water test.

How will treated water differ at your tap when using the Pentair system?

After water passes through the Pentair Nitrate & Nitrite (Well) Filter, nitrate concentrations can be substantially reduced, improving safety where nitrate was elevated. Water clarity, taste, and odor generally remain unchanged since nitrate does not contribute to aesthetic qualities. The main benefit is that water becomes safer for drinking and cooking for vulnerable household members.

What should you not conclude from El Paso County nitrate data about your own water?

Do not assume your well or tap water contains nitrate levels exactly like those in area studies. Regional data shows a range of nitrate levels across sampled wells, not the condition of an individual source. Also, detection does not mean your well water violates health standards or is unsafe. Only testing your own water can provide the information needed to decide if treatment is appropriate.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2024-08-22. 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 Nitrate in the 111ALFP aquifer (El Paso County): 438 results from 10 wells, median 7.56 mg/L, range 0.847-48.4 mg/L; 188 above a health-based federal MCL (federal MCL 10.0 mg/L)
