The U.S. Geological Survey's groundwater sampling in Doña Ana County, focusing on aquifer 112SNTF, shows a median pH of 7.9 standard units based on 133 results from 49 wells collected between 2010 and 2024. This data indicates pH values ranging from 6.8 to 9.1 standard units, all above the EPA secondary standard lower limit of 6.5 for aesthetic and corrosivity considerations.
1. Effects of Household Size and Property Usage on pH Management
In households with higher water demand, such as larger families or seasonal properties, managing water with pH near the lower end of the range (closer to 6.8) may require different approaches than smaller or year-round residences. Increased water volume can influence treatment system sizing and flow rates, affecting how well pH adjustments are maintained during periods of peak use. Seasonal homes might experience different water chemistry due to stagnation or regional usage patterns when unoccupied for extended durations.
2. Interpreting the Extent of Sampling and Its Statistical Meaning
The pH range reported is drawn from 133 samples from 49 wells that vary in depth from 110 to 1880 feet. While this dataset offers a solid overview of the aquifer's pH levels, it does not specify conditions in any individual well or household water source. A smaller sample may not capture full variability, meaning localized variations in water pH can occur beyond this range. For personal water decisions, direct testing of the household water supply is essential to confirm specific pH levels.
3. How the Fleck System Addresses Acidic Water
The Fleck Acidic / Low-pH Water Filter is designed to address low pH in residential water supplies. It works by neutralizing acidity through filtration media that raise pH to a more neutral range, improving water taste and reducing potential effects on plumbing materials. This technology ships ready to configure, allowing household water systems to treat pH concerns effectively once the demand parameters are assessed.
4. Differentiating Public System Records from Private Well Testing
Public water system records typically reflect average or expected water quality over a broad area and can miss localized shifts in pH that private wells might exhibit. While Doña Ana County’s aquifer data provide regional context, individual well water can differ due to geology, well depth, and usage. A private well user should conduct laboratory tests focusing on their water to know actual pH levels, especially if signs of acidic water appear.
5. Comparing Doña Ana County’s pH Data With Neighboring Areas
When looking at pH data from adjacent counties, variations often exist linked to different aquifer characteristics and sampling scopes. It’s important to avoid overinterpreting slight differences, as pH ranges can overlap regionally without indicating a change in water quality severity. The Doña Ana County median pH near 7.9 standard units fits within typical neutral to slightly alkaline groundwater, consistent with many southwestern U.S. aquifers.
For household water demand in Doña Ana County, understanding these data alongside personal water testing clarifies the need for pH treatment. The Fleck Acidic / Low-pH Water Filter offers a documented method to help balance water pH efficiently, aligned with measured household water usage and demand.

Source: USGS groundwater sampling. Sampled 2024-05-20. 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 pH in the 112SNTF aquifer (Doña Ana County): 133 results from 49 wells, median 7.9 standard units, range 6.8-9.1 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 0 of 133 sampled results fell below 6.5
