About

The CDC National Wastewater Surveillance System (NWSS) tracks the presence and concentration of infectious disease pathogens in municipal wastewater systems across the United States. Established during the COVID-19 pandemic and expanded to influenza A, RSV, mpox, and avian influenza A (H5), NWSS provides early community-level warning of viral infection trends independent of clinical healthcare-seeking behavior or diagnostic testing access.

Through Fibric, an operator references municipal wastewater viral metrics and county-level percent changes to anticipate regional epidemic surges, proposing staffing contingency plans and facility protective measures before clinical hospitalization spikes occur.

This is a reference listing. It documents what Fibric would read from National Wastewater Surveillance System (NWSS) and what it could propose, based on the publisher's published interfaces. Fibric builds it under a managed deployment when you request it; selecting it here installs nothing.

Inputs

  • Wastewater viral concentration metrics normalized by wastewater flow rates or human fecal indicators
  • 15-day percentage changes in SARS-CoV-2 viral gene copy concentrations across sampling utility sewersheds
  • State and territory wastewater viral activity level classifications categorized from very low to very high
  • Multi-pathogen surveillance tables covering influenza A, RSV, mpox, and influenza A(H5)
  • Socrata Open Data API endpoints providing site-level and county-level time-series datasets on data.cdc.gov

Proposed actions

Read-only. This feed informs operators; it changes nothing.

Proposed actions are target capabilities. Every action runs propose-first and needs a validated deployment and the appropriate permissions.

What you can build

  • Detect community pathogen spikes prior to clinical absenteeism

    Monitor local sewershed viral concentration trajectories, proposing early workforce shift standby allocations before clinical case counts register in outpatient reports.

    With Shift Coverage, Open Shift Offer

  • Adjust HVAC ventilation based on wastewater viral activity

    Track state wastewater activity levels, proposing increased outdoor air ventilation rates and filter inspections for buildings located in high-activity counties.

    With CO2 Ventilation, Filter Change

Requirements

  • Integration with CDC SODA REST API or automated synchronization with daily tabular wastewater datasets
  • Mapping of utility sewershed coverage boundaries and treatment plant locations to corporate facility assets
  • Normalization logic to handle varying assay methodologies across state public health and commercial testing laboratories
Authentication
None. NWSS data hosted on data.cdc.gov is publicly queryable without authentication; an optional Socrata app token increases rate limits.

Limits

  • Wastewater surveillance covers populations served by municipal sewer systems, excluding areas relying on private septic tanks
  • Sampling frequencies vary between weekly and bi-weekly collections across participating treatment utility sites
  • Rainfall dilution and industrial effluent variations can temporarily affect raw concentration calculations

Access and pricing

Questions and answers

How does wastewater surveillance provide an early warning?
Infected individuals shed viral particles in wastewater days before symptoms appear or clinical tests are administered, providing early detection of community transmission surges.
What pathogens are monitored through the NWSS platform?
NWSS monitors SARS-CoV-2, influenza A, respiratory syncytial virus (RSV), mpox, and avian influenza A(H5) in participating wastewater treatment facilities.
How often is CDC wastewater data refreshed?
CDC updates wastewater surveillance datasets multiple times per week on data.cdc.gov as state laboratories and utilities submit testing results.
