Alachlor (Lasso) violations in North Carolina

11 active public water systems in North Carolina had a Alachlor (Lasso) violation in the past three years, 1 of them in the latest quarter of EPA's data. What Alachlor (Lasso) is and why it matters.

Health effects: Chronic exposure to alachlor is associated with eye, liver, kidney, and spleen damage. EPA classifies it as a probable human carcinogen (Group B2) based on animal studies showing nasal tumors. Long-term exposure above the MCL is the primary concern; children may be more susceptible to carcinogenic effects.

About this data

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

Source: the U.S. EPA's Enforcement and Compliance History Online system (ECHO), which publishes the federal Safe Drinking Water Information System. EPA's terms and values are shown as published. The North Carolina 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.
