Here is what the EPA's own data shows about tap water in Quitaque. According to EPA SDWIS data retrieved October 2026, Quitaque is served by 1 active community water system, together reported to serve about 342 people.
As of October 2026, EPA records show 53 violations across the community water system(s) serving Quitaque, going back to the earliest EPA record. 41 of these are classified by the EPA as health-based (a contaminant recorded above the limit the EPA tracks); the rest are monitoring or reporting violations. Each is listed by system below, with its status.
Health-based Nitrate: a health-based violation (a contaminant recorded above the limit the EPA tracks), recorded 41 times between January 2016 and January 2026. The EPA record lists a level of 14 MG/L; the limit (MCL) is 10 MG/L. EPA records do not show all of these as returned to compliance.
Monitoring Lead and Copper Rule: a monitoring or reporting violation (a required test or report was late or missed — not a measured exceedance), recorded 2 times between December 2014 and October 2023. All have since returned to compliance, per EPA records.
Monitoring Revised Total Coliform Rule: a monitoring or reporting violation (a required test or report was late or missed — not a measured exceedance), recorded 2 times between February 2021 and September 2021. All have since returned to compliance, per EPA records.
Monitoring Chlorine: a monitoring or reporting violation (a required test or report was late or missed — not a measured exceedance), recorded 3 times between April 2016 and April 2021. All have since returned to compliance, per EPA records.
Monitoring Public Notice: a monitoring or reporting violation (a required test or report was late or missed — not a measured exceedance), recorded 5 times between November 2012 and March 2020. All have since returned to compliance, per EPA records.
What this means
A health-based violation means a contaminant was recorded above the limit the EPA tracks for it. A monitoring or reporting violation means a required test or report was late or missed — not that a contaminant was measured above a limit. “Returned to compliance” means the EPA recorded the issue as resolved.
