In an effort to better understand the scope of potential and existing PFAS contamination around the state, the New Mexico Environment Department (NMED) has worked with state and federal partners to conduct sampling for PFAS in water around the state. Data from other sampling is also posted here.

Cannon Air Force Base (Curry County) and Holloman Air Force Base (Otero County)

These data represent results from testing done by NMED, Department of Health and the U.S. Air Force at and around Cannon Air Force Base and Holloman Air Force Base, unless otherwise noted, up to 2019.


PFAS Delineation Investigation

NMED began work on a PFAS delineation investigation in February 2021. This work is related to the previous use of per- and poly-fluorinated alkyl substances (PFAS) at Cannon Air Force Base (AFB), located near the city of Clovis in Curry County, and Holloman AFB, located near the city of Alamogordo in Otero County.

The size of the PFAS groundwater contamination plumes at Cannon AFB and Holloman AFB are unknown at this time. Given the potential magnitude of these groundwater plumes, NMED is undertaking an efficient and technically defensible data-driven investigation that will enhance our understanding of the size and movement of the existing PFAS plumes. The objectives of the investigation are to:

  • Provide better definition of existing groundwater plume geometry and predictions of future plume migration and surface water contamination and conveyance, including empirically derived rates of movements of contaminants;
  • Identify and sample all participating public and private water supply wells that have had PFAS detections or are at potential risk of current or future PFAS contamination;
  • Establish regular groundwater monitoring programs;
  • Investigate the extent to which resident and migratory waterfowl at the Lake Holloman Wetlands Complex are contaminated with, or otherwise adversely affected by, PFAS.

Well testing in Curry and Roosevelt Counties

In 2021, through an appropriation from the New Mexico Legislature, the NMED is studying potential PFAS contamination in Curry and Roosevelt Counties. NMED will collect water samples at wells in these two counties, in coordination with the well owners that volunteered to participate in the study. Samples collected from March to May 2021 will be analyzed for the presence and levels of up to 33 different PFAS compounds, including PFOA and PFOS – the two most widely known PFAS chemicals. NMED will post the data results to this webpage by Summer/Fall 2021.

Statewide PFAS Study

The NMED Drinking Water Bureau is partnering with the U.S. Geological Survey (USGS) to sample for 28 PFAS chemicals in groundwater and surface water around New Mexico, including multiple public drinking water systems. Results can be found at the USGS online database: but are also available in this easy-to-read spreadsheet.


PFAS Sampling at Los Alamos National Laboratory

The NMED Department of Energy-Oversight Bureau (DOE-OB) began sampling of PFAS in the fall of 2020 at Los Alamos National Laboratory. As part of its ongoing mission, the DOE-OB performs independent sampling and monitoring of Department of Energy (DOE) legacy operations. Los Alamos National Laboratory PFAS sampling data obtained by the DOE-OB is uploaded to the Intellus New Mexico environmental database located at

U.S. EPA Unregulated Contaminant Monitoring Rule

EPA uses the Unregulated Contaminant Monitoring Rule (UCMR) to collect data for contaminants that are suspected to be present in drinking water and do not have health-based standards set under the Safe Drinking Water Act (SDWA). The EPA included six PFAS chemicals in UCMR testing that occurred from 2013-2015.
