Review public water systems serving PROVO, see where open violations appear in EPA SDWIS records, and use ZIP-based map overlays to approximate which utility may cover different parts of the city.
This city summary turns red when any mapped system has an open health-based violation, amber when only open non-health-based issues are listed, and green when no open violations are found.
Open issues and historical records are shown separately so users can clearly distinguish current compliance risk from past context.
EPA public water data does not include exact service polygons. This map approximates each system's footprint using the ZIP code attached to that system record and Census TIGER ZIP boundaries.
Cards are sorted by population served. Expand a system to review its violation history, open issues, and plain-English context.
SDWIS is the EPA's Safe Drinking Water Information System. It records public water systems, compliance activity, and violations under the Safe Drinking Water Act. It is useful for identifying patterns and open compliance issues, but it is not a real-time alert feed.
Health-based violations usually mean a contaminant limit, treatment requirement, or other protective standard was not met. Monitoring violations often mean required sampling, testing, reporting, or public notice steps were late or incomplete. Those amber issues matter because they reduce visibility into whether standards were checked properly, even when they do not automatically prove the water is unsafe.
Public notification tiers help explain urgency. Tier 1 is the most urgent, Tier 2 is still health-related but generally less immediate than Tier 1, and Tier 3 usually covers monitoring, reporting, or other less urgent notices.
SDWIS is the EPA Safe Drinking Water Information System. It tracks public water systems, their compliance records, and violations such as health-based exceedances, treatment technique issues, monitoring gaps, and public notice requirements.
Health-based violations generally mean a drinking water standard or required treatment rule was not met. Monitoring violations usually mean the system did not complete or report a required test on time. Monitoring issues do not automatically mean the water is unsafe, but they reduce visibility into compliance.
Tier 1 notices are the most urgent, Tier 2 notices cover other health-based issues that still require direct notice, and Tier 3 notices are usually used for monitoring, reporting, or less urgent compliance matters.
No. EPA SDWIS data is compliance-oriented and can lag behind local events. Always check your utility's website, city emergency alerts, or local health department for real-time boil water advisories and outage notices.
