A failed EPA sanitary survey is one of the most consequential events a small water system can face. The findings trigger a formal enforcement timeline, show up permanently in your SDWIS record, and follow your system into every future regulatory interaction. Understanding exactly what happens — and what the timeline is — is the first step to getting through it without compounding the problem.

What "Failed" Means in a Sanitary Survey (40 CFR 142.16)

The EPA and state primacy agencies evaluate water systems across eight survey elements: source water, treatment, distribution system, finished water storage, pumps and controls, monitoring and reporting, system management, and operator compliance. Surveyors assign findings at three severity levels: recommendations (minor), deficiencies (require correction), and significant deficiencies (serious failures that directly affect public health protection). A "failed" survey in regulatory terms means your system received one or more significant deficiencies.

The Immediate Consequences (Days 1–30)

Public notification is required. Under 40 CFR 141 Subpart Q, uncorrected significant deficiencies can trigger public notification obligations — for groundwater systems, the Groundwater Rule special notice (Tier 3 timing: within 12 months, or via the next CCR for community systems). Your state's letter sets the exact obligations and the clock.

Your SDWIS record is updated. EPA's Safe Drinking Water Information System reflects deficiency findings. This is public data, visible to your state primacy agency, EPA region, neighboring systems, and any third party who looks — including a free lookup at orevant.com.

A corrective action deadline is set. State primacy agencies set mandatory timelines for correcting significant deficiencies — commonly 30, 60, or 90 days depending on severity.

What Happens If You Don't Fix It

  • Monitoring and reporting violations — if the deficiency stemmed from missed monitoring, those become separate enforcement actions that compound your record.
  • Formal administrative order — states can issue Administrative Compliance Orders (ACOs) requiring specific corrective actions; violating an ACO can trigger penalties.
  • Civil penalties — under SDWA section 1414, EPA and states can assess penalties starting at the statutory $25,000 per day per violation (inflation-adjusted maximums are now substantially higher) for systems that fail to comply.
  • Escalation at the next survey — an unresolved significant deficiency from one survey automatically escalates at the next, becoming a direct basis for stronger enforcement.

The Corrective Action Process

Step 1 — Read the report in full. Significant deficiencies, standard deficiencies, and recommendations each carry different timelines. Don't treat them the same.

Step 2 — Write a corrective action plan. Most states require a written plan addressing each significant deficiency within 45–60 days, including specific corrective steps, responsible personnel, and a completion timeline.

Step 3 — Contact your primacy agency immediately. Systems that reach out proactively with a plan before the state calls receive more flexible timelines and demonstrate good faith.

Step 4 — Document everything. Work orders, lab results, invoices, and operator logs are your evidence file if enforcement escalates. Keep records a minimum of five years.

Step 5 — Request technical assistance if needed. EPA's Technical Assistance Centers and state primacy agencies offer free or low-cost help to small systems — it doesn't waive enforcement, but it provides resources small systems often can't afford.

How Orevant Helps After a Failed Survey

The free compliance lookup at orevant.com shows exactly what your current SDWIS record reflects — open violations, monitoring gaps, and deficiency history. Before you respond to the state or write your corrective action plan, you need to know what your official record shows. Orevant goes further: it maps every open item against your state's corrective action requirements and federal timelines, so you know what to address first and what a compliant plan must include.

FAQ

How long does a significant deficiency stay on my record?

Deficiency findings persist in SDWIS until resolved and verified by your primacy agency — and unresolved items escalate at your next survey.

Is a sanitary survey the same in every state?

The eight elements are federal; state primacy agencies set specific schedules and corrective action timelines, which Orevant maps by state.
