Glyphosate violations in Colorado

2 active public water systems in Colorado had a Glyphosate violation in the past three years, 1 of them in the latest quarter of EPA's data. What Glyphosate is and why it matters.

Health effects: Long-term exposure above the MCL is associated with kidney and reproductive damage in animal studies. EPA's current classification does not designate glyphosate as a human carcinogen, though IARC classifies it as probably carcinogenic (Group 2A). This classification remains a subject of active scientific and regulatory debate.

About this data

A system is counted once if any of its violations in the past three years involved Glyphosate, including monitoring and reporting lapses. Rules violated and status in the table are for the whole system, not Glyphosate alone.

The Colorado records are from EPA's data refresh of Oct 7, 2026; EPA refreshes this data quarterly, and states report to EPA with a lag of three to six months, so the newest violations may not appear yet.
