Regulatory basis

How Atrazine is regulated

What the enforceable limit actually obliges a utility to do, and how it differs from the health-based goal it is measured against.

For Atrazine the enforceable limit and the health goal are the same number, 3 µg/L. EPA set the Maximum Contaminant Level (MCL) at the health goal (MCLG), so there is no feasibility gap here: meeting the legal limit also means meeting the health-based goal. A value above 3 µg/L is both an exceedance of the goal and a violation of the enforceable standard.

Results are reported in µg/L. A laboratory result and the limits above are only comparable when both are expressed in that same unit — a value in a different unit will be off by orders of magnitude. WaterQualityLens groups Atrazine under Pesticide for navigation; the grouping is ours, the limits are the regulator’s.

Certification scope

Which certifications actually remove Atrazine

Only NSF/ANSI 53, 58 and 401 are health-contaminant standards. A product certified only to Standard 42 (aesthetics) or 372 (lead-free materials) has not been verified to reduce Atrazine, however the box is worded.

  • NSF/ANSI 53

    Counts — health standard

    Health effects: lead, VOCs, cysts, chromium, and (post-P473) PFAS reduction.

    No filter in our registry holds a verified NSF/ANSI 53 claim for Atrazine. That means we hold no certification record — not that the standard could never cover it.

  • NSF/ANSI 58

    Counts — health standard

    Reverse osmosis: dissolved inorganics, arsenic, hexavalent chromium, and total PFAS.

    No filter in our registry holds a verified NSF/ANSI 58 claim for Atrazine. That means we hold no certification record — not that the standard could never cover it.

  • NSF/ANSI 401

    Counts — health standard

    Emerging/incidental compounds: pharmaceuticals and select trace contaminants.

    2 filters in our registry hold an independently verified NSF/ANSI 401 claim for Atrazine, listed below.

  • NSF/ANSI 42

    Does not count — not a health standard

    Aesthetic effects: chlorine, taste, odor, particulates. No health-contaminant protection.

    No registry product lists Atrazine under NSF/ANSI 42. It would not count as verification of Atrazine reduction in any case.

  • NSF/ANSI 372

    Does not count — not a health standard

    Lead-free materials (manufacturing content only). Not a water-treatment claim.

    No registry product lists Atrazine under NSF/ANSI 372. It would not count as verification of Atrazine reduction in any case.

Counts are of active products in the WaterQualityLens filter registry holding a verified claim for contaminant code 2050 under that standard, as recorded by the certifying body (NSF, WQA, or IAPMO). Certification is granted per contaminant, not per product: a filter certified to Standard 53 for one contaminant is not thereby certified for Atrazine.

Certified reduction · commercial placements

Filters verified to reduce Atrazine

These filters hold an independent NSF/ANSI health certification (Standard 53, 58, or 401) specifically for Atrazine. Certification against a health standard means an accredited lab verified the filter reduces this contaminant — a materials-only claim such as NSF 42 or 372 does not.
