The below Public Metric Data Dictionary (available for download as an Excel file or 3 CSV files) and the Public Concentration Data Dictionary (available for download as an Excel file or 2 CSV files) describe a subset of analyzed wastewater data available on CDC’s COVID Data Tracker.

State, tribal, local, or territorial (STLT) health departments submit data to the NWSS DCIPHER platform using a standard collection instrument and format specified in the NWSS Reporting Data Dictionary, available for download below as an Excel file or as 4 CSV files (files last modified on July 10, 2023).

Testing: Information about sample concentration, extraction, and quantification methods, as well as viral recovery efficiency and molecular inhibition measurements, are needed to compare wastewater collected from multiple locations and analyzed by different testing laboratories.

Sampling: The sample collection time, date, and location, as well as the sample type (grab or composite) and wastewater flow rate during sample collection, are needed to understand sample collection conditions.

Wastewater treatment plant: Information on the wastewater treatment plant service area, number of people served by the utility, and treatment processes is needed to understand the wastewater source.

These data are collected during multiple steps of the sample collection and testing processes. A minimum set of data is required to interpret SARS-CoV-2 wastewater measurements for use in the COVID-19 response.
