The Deming Municipal Water System in Luna County, New Mexico, uses groundwater to supply water to approximately 16,788 people across 6,127 connections. According to the EPA’s Unregulated Contaminant Monitoring Rule 5 (UCMR5) results collected between January 31, 2024, and March 18, 2026, no PFAS compounds have been detected above reporting levels in this public water system. This means no measurement of PFAS was recorded above the smallest concentration the laboratory could reliably quantify in these samples. It is important to understand what this monitoring data means for your household and what further steps you might consider.
If you wonder why PFOA and PFOS concentrations are expressed in nanograms per litre with four decimal places
PFAS, or per- and polyfluoroalkyl substances, are a group of fluorinated compounds often called "forever chemicals" because they break down very slowly in the environment. Measuring them at extremely low concentrations requires precise units. Nanograms per litre (ng/L), equivalent to parts per trillion (ppt), describe how many billionths of a gram are found in one liter of water. Reporting levels with four decimal places, such as 0.004 µg/L, define the lowest concentration the lab can confidently identify. When EPA reports no PFAS detected above this level, it means concentrations, if present, are below this trace threshold, not necessarily zero.
If you want to know why granular activated carbon and ion-exchange resins are treated differently for PFAS removal
Two common technologies are documented for treating PFAS in water supply: granular activated carbon (GAC) beds and ion-exchange resins. GAC adsorbs PFAS compounds onto its porous surface, effectively trapping them, while ion-exchange resins operate by swapping PFAS molecules with harmless ions in water through a chemical exchange. Each has distinct capacities and regeneration methods. Understanding these differences helps when choosing a solution tailored to your water system’s conditions and the types of PFAS present.
If you want to know how the documented treatment technology addresses PFAS in your water
The Pentair PFAS Forever Chemicals Filter combines the benefits of granular activated carbon and ion-exchange media to reduce PFAS concentrations effectively when water passes through its filtration system. This approach targets multiple PFAS types, including PFOA, PFOS, PFHxS, PFNA, and others listed in EPA monitoring, by adsorbing and exchanging these molecules to lower their presence in household water. It ships ready to configure for residential settings and is a documented method to manage PFAS in domestic water supplies.
If you want to understand how sample depth, well depth, or source type influence PFAS findings
PFAS concentrations can vary depending on how deep groundwater wells are and the characteristics of the source aquifer. Shallower wells or sources near surface contamination may show different PFAS profiles compared to deep wells. The Deming system draws from groundwater, but without individual well testing, the system-wide data reflects an overall status rather than a specific home’s water condition. Thus, your well or tap water could differ from municipal data, highlighting the need for individual testing to know your household’s exact PFAS levels.
If you want to know which household faucets, appliances, or processes are affected first by PFAS and why
Water treatment devices like the Pentair PFAS Forever Chemicals Filter connect typically at points of use where drinking and cooking water is drawn, such as kitchen faucets. These points are prioritized because PFAS, even at low levels, may be ingested most directly there. Appliances involved in food and beverage preparation can concentrate or interact with PFAS compounds, so filtering water at these outlets addresses the most immediate exposure routes within a home. Other uses like bathing or laundry generally have lower ingestion risk and are treated differently.
If you want to know how to prioritize testing and rule out issues with your water, from basic checks to laboratory analysis
Begin with simple observations like taste, odor, or visible changes in water quality, although PFAS are not detectable by sensory means. Next, consider verifying municipal water quality reports regularly; the Deming system reports no PFAS detected above reporting levels. To confirm your own water, arrange for a certified laboratory test focusing on PFAS compounds, specifying those measured by UCMR5 such as PFOA, PFOS, PFHxS, PFNA, and others. This lab analysis is the definitive step to know your home's PFAS status and decide on filtration options.
Conclusion: The single test you should order and how its results resolve your PFAS concerns
To answer if PFAS are a concern in your household water in Deming, the essential step is to commission a laboratory test for the group of per- and polyfluoroalkyl substances listed in the EPA's UCMR5 monitoring. This test measures PFAS concentrations in nanograms per litre, allowing you to compare results to federal MCLs effective in 2024. A result below these levels confirms your water aligns with current safety standards. Using the Pentair PFAS Forever Chemicals Filter offers a documented technology to reduce PFAS in your water if the test shows detectible concentrations, helping manage potential exposure to 'forever chemicals.'
