Nitrate in Bernalillo County Groundwater: What Area Sampling Reveals for Residential Treatment Choices

What is the typical maintenance rhythm for nitrate treatment using the Fleck System?

The Fleck Nitrate & Nitrite (Well) Filter ships ready to configure for residential use and requires a maintenance schedule based on the system’s specific design and household water demand. Typical maintenance involves periodically checking filter performance and replacing media as specified by operational guidelines, which helps maintain effective reduction of nitrate and nitrite without frequent interruptions or complex upkeep.

How many samples and wells provide the data behind nitrate figures for Bernalillo County, and what does a small sample size imply?

The U.S. Geological Survey conducted groundwater sampling in Bernalillo County’s aquifer 112SNTFU, collecting 358 nitrate results from 16 separate wells between May 2013 and January 2020. These wells ranged from 100 to 1630 feet deep. While this is a substantial dataset for area-wide assessment, any single household’s water could vary due to the limited number of samples relative to the entire population of wells. A smaller or localized sample might not capture all variability, so individual well testing is essential to determine specific water quality.

Once nitrate treatment with the Fleck System is in place, how does the water quality at the tap change?

The Fleck Nitrate & Nitrite (Well) Filter reduces concentrations of nitrate and nitrite, which are compounds naturally entering groundwater through sources like fertilizers and septic systems. Treated water typically shows reduced nitrate levels, mitigating concerns associated with high nitrate such as taste or potential health considerations in sensitive groups. This treatment improves water quality by lowering nitrate from the levels detected in area sampling to lower ranges suitable for household use.

What information should a household record before seeking further water treatment advice?

To make the best treatment decisions, households should obtain a recent water quality test from their own well or tap, specifically measuring nitrate concentration. Note the test date, sampling depth, and if possible, other constituents that could affect treatment choices. Comparing these results to the area’s documented nitrate range—from 0.042 to 8.28 mg/L in Bernalillo County—helps contextualize the household’s water but cannot replace direct testing.

How does nitrate enter Bernalillo County’s groundwater or water distribution system?

Nitrate in Bernalillo County’s aquifer 112SNTFU commonly originates from natural soil processes and human activities such as agricultural fertilizer application and septic system effluent. These sources contribute nitrate that leaches into groundwater over time. The variation in measured nitrate—from below detection to 8.28 mg/L in sampled wells—reflects differences in local land use, soil characteristics, and hydrology within the aquifer’s reach.

What should a household not conclude from the nitrate data for Bernalillo County?

Even though all sampled results in this data set fall below federal nitrate thresholds for safety, this does not guarantee any individual household’s water meets these standards. Detection of nitrate in area wells is common but not a violation or health conclusion on its own. Only a recent test of the household’s actual water source can establish its nitrate concentration, and decisions about treatment should be based on those personal results rather than the wider area data alone.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2020-01-09. 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 112SNTFU aquifer (Bernalillo County): 358 results from 16 wells, median 0.7365 mg/L, range 0.042-8.28 mg/L; none above any federal threshold
