PFAS Contamination Snapshot
Santa Fe, NMPFAS & Water Quality Data
Santa Fe, NM| Contaminant | Detected Level | EPA Limit (MCL) | Status |
|---|---|---|---|
| PFAS (Total) | Not Detected | 4.0 ppt (PFOA/PFOS) | Not Detected |

EPA PFAS Standards
What they mean for Santa FeFinal PFAS Rule (Current)
In April 2024, the EPA finalized the first-ever legally enforceable Maximum Contaminant Levels for PFAS in drinking water:
Compliance Monitoring Begins
Santa Fe Water Division in Santa Fe will be required to test and report results.
Full Compliance Deadline
All public water systems must meet the MCLs or install treatment to reduce PFAS below legal limits.
EPA finalized enforceable PFAS limits in 2024: 4 ppt for PFOA, 4 ppt for PFOS individually.
Health Risks of PFAS Exposure
Santa Fe residents should be awarePFAS exposure is linked to: kidney and testicular cancer, thyroid disease, immune system suppression, reproductive issues, liver damage, and developmental effects in children.
Cancer Risk
PFOA is classified as a possible human carcinogen. Studies link PFAS exposure to kidney cancer, testicular cancer, and elevated risks of bladder and liver cancers.
Thyroid Disease
PFAS disrupt thyroid hormone regulation. Exposure is associated with hypothyroidism, thyroid cancer, and metabolic dysfunction — particularly dangerous during pregnancy.
Immune System
PFAS reduce vaccine antibody response and suppress immune function. Children with higher PFAS blood levels show weaker responses to routine vaccinations.
Reproductive & Developmental
Linked to decreased fertility, pregnancy-induced hypertension, preeclampsia, low birth weight, and developmental delays in children exposed in utero.
Liver & Kidney Damage
PFAS accumulate in the liver and kidneys. Chronic exposure is associated with elevated cholesterol, liver enzyme changes, and impaired kidney function.
Cardiovascular Effects
Strong evidence links PFAS to elevated total and LDL cholesterol levels, increasing risk of heart disease, atherosclerosis, and stroke over time.
What Are PFAS?
How they get into Santa Fe's waterPFAS (per- and polyfluoroalkyl substances) are a group of over 14,000 synthetic chemicals used since the 1940s. Their carbon-fluorine bond — one of the strongest in chemistry — makes them virtually indestructible in nature, earning the name "forever chemicals."
Industrial Discharge
Factories manufacturing or using PFAS release contaminated wastewater into rivers and groundwater. Santa Fe's rio grande and local reservoirs source may be affected.
Firefighting Foam (AFFF)
PFAS-containing aqueous film-forming foam used at military bases, airports, and fire training facilities seeps into soil and groundwater.
Landfill Leachate
Consumer products containing PFAS break down in landfills. PFAS-laden leachate can contaminate groundwater for decades.
Biosolids & Runoff
Wastewater biosolids applied to farmland as fertilizer carry PFAS into soil and eventually into watershed systems.
Removing PFAS from Santa Fe Water
Reverse Osmosis (RO)
Under-sink RO systems force water through a semi-permeable membrane, removing PFAS along with lead, arsenic, and other contaminants.
- Highest PFAS removal rate available
- NSF/ANSI 58 certified systems available
- Removes virtually all contaminants
- Point-of-use — treats drinking water directly
Activated Carbon (GAC)
Granular activated carbon and carbon block filters adsorb PFAS compounds. Better for long-chain PFAS (PFOA/PFOS) than short-chain variants.
- More affordable than RO
- NSF P473 certified options available
- Also removes chlorine, taste, and odor
- Pitcher, faucet, or under-sink formats
Ion Exchange Resin
Anion exchange resins specifically designed for PFAS removal. Effective for both long-chain and short-chain compounds.
- Effective on short-chain PFAS
- High flow rate capability
- Whole-house systems available
- Long media lifespan
No PFAS-specific filter is needed for Santa Fe. A standard carbon filter handles chlorine and improves taste.
