Real EPA measurements of arsenic for New Mexico water systems — Six-Year Review compliance samples 2012–2019 (historical). Methodology
EPA does not publish per-city arsenic measurements for New Mexico in the datasets we use, so this section shows what regulators actually recorded: every Safe Drinking Water Act violation tied to arsenic at the 1 New Mexico public water systems we track, since 2016. Source: EPA SDWIS via ECHO (2026 Q2 extract).
No arsenic violations on record. None of the 1 tracked New Mexico systems has a SDWIS violation for arsenic since 2016. That means no monitoring, reporting or limit violation was logged — it is not a lab result for your tap. Check your utility's annual Consumer Confidence Report for measured levels.
Every New Mexico system with a arsenic result in EPA's data, sorted by level. Averages of 2012–2019 finished-water samples, non-detects counted as zero — historical, not today's tap.
No arsenic detections have been reported in New Mexico cities.
Arsenic is a known human carcinogen linked to cancers of the skin, bladder, lung, kidney, and liver. Long-term exposure can cause skin damage including color changes and lesions. Arsenic exposure is associated with cardiovascular disease, diabetes, and neurological effects. Studies have shown links between arsenic exposure and developmental effects in children, including reduced IQ and learning disabilities.

Based on our analysis of EPA Safe Drinking Water Information System (SDWIS) data and local water utility reports,arsenic has been detected in 0 New Mexico water systems.
The EPA set the arsenic MCL at 0.010 mg/L (10 ppb) in 2001. The EPA MCL for arsenic is 0.01 mg/L. This limit is set to protect public health based on available scientific evidence about the contaminant's health effects.
0 New Mexico cities have arsenic detected in their water supply. All tested cities are within EPA safety limits.
Increased cancer risk (skin, bladder, lung), skin damage, cardiovascular disease, diabetes. The most vulnerable groups include children and people with cardiovascular conditions.
The most effective methods for removing arsenic include Reverse Osmosis, Adsorption Media (Iron-Based), Distillation. Look for filters certified by NSF/ANSI for arsenic reduction.
The EPA Maximum Contaminant Level (MCL) for arsenic is 0.01 mg/L.The EPA set the arsenic MCL at 0.010 mg/L (10 ppb) in 2001.
This page shows what New Mexico utilities reported for arsenic. It cannot tell you what is coming out of your own tap: utility samples are taken across a whole system and averaged, levels vary by address and season, and anything picked up after the water leaves the main never appears in their report.
