This database was developed to support the Emerging Contaminants Program (ECP) in evaluating emerging contaminants, including Per and Polyfluoroalkyl Substances (PFAS). Publicly available data is provided through a secure portal for use by ECP, participating New Mexico public water systems, consultants, and stakeholders.

The platform provides public access to the data used in ECP’s initial monitoring effort and supports transparency by enabling users to easily view results across geography and analytes. The database integrates ECP sampling results with relevant spatial datasets from local, state, and federal sources.

This is an evolving resource that reflects current ECP testing results for select drinking water analytes. Content will be updated as additional validated data becomes available.

Data displayed here is provided in good faith and collected in alignment with the ECP Sampling Standard Operating Procedure. Results may be updated or revised as assessments continue, or new information is verified.

Each water system participating in ECP has been sampled two to four times, depending on what is required by the regulation, and Analytical Results are available and shown for each of those events under a tab with that name. A summary of results is available for each system under "Notes" in the General Information tab.

Known Limitations of the Data or Detection Thresholds

Several limitations apply to the available data within the Data Management System (DMS):

• Data Availability: For most systems without detections above regulatory thresholds, the Emerging Contaminants Program (ECP) data only includes results for entry points to the distribution system (EPTDS), and not for source water.
• Sampling Frequency and Coverage: At any given time, depending on the type of system, the DMS may only display sampling results from a single sampling event or location.
• Monitoring Scope: The current dataset represents results from the initial monitoring requirements. No additional data collection is anticipated unless the New Mexico Environment Department (NMED) obtains primacy or water systems voluntarily report data to NMED.
• Program Participation: Some systems do not qualify for the monitoring program, and others have chosen to opt out, resulting in incomplete statewide coverage.
• Metals Data: EPA Method 200.7 covers numerous trace metals and elements, but only lithium and manganese were selected for ECP analysis. Thus, these are the only Method 200.7 analytes reported in the DMS.

Regarding detection thresholds, these are not considered limitations, as the reporting limits (RLs) are substantially lower than the applicable maximum contaminant levels (MCLs), ensuring adequate sensitivity for detection.

On April 26, 2024 the U.S. Environmental Protection Agency (USEPA) published the final National Drinking Water Rule (NPDWR) for six Per- and polyfluoroalkyl substances. The standards are summarized in the following table.

^a The final rule published 4/26/24 did not include a Maximum Contaminant Level Goal, MCL, or Trigger Level for PFBS individually, but as a mixture.
