  • Sample Collection and Transportation

    Information about the two most commonly used methods to collect wastewater samples- composite sampling and grab sampling. 


    Composite Sample Collection/Storage/Transport

    A composite sample is collected from an autosampler that collects numerous small samples taken over regular intervals over a period of time, usually 24 hours.

    Document: Example Standard Operating Procedure for  Sample Collection/Storage/Transportation to Lab (Composite Samples)-This document describes procedures for safe transfer of wastewater samples from wastewater treatment plants to your state health department's laboratory for RNA extraction and analysis. 


    Grab Sample Collection/Storage/Transport

    A grab sample is collected by lowering a specimen container into the sewer. 

    Video: Grab Sample Overview- This video provides an overview of the process of collecting grab samples for wastewater surveillance.

     

     

     

     

     

     

    Document: Sample Standard Operating Procedure for Sample Collection/Storage/Transportation to Lab (Grab Samples)-This document outlines procedures for safe transfer of wastewater samples from wastewater treatment plants to your state health department's laboratory for RNA extraction and analysis.

  • Partnerships with Wastewater Utilities and Public Health Agencies

    Forming strong partnerships between wastewater utilities departments and public health agencies is one of the keys to wastewater surveillance program success. Resources in this section are designed to help you build and maintain these partnerships.

    Document: Sample Memorandum of Understanding for Health Agencies and Wastewater Treatment Plants (PDF)- This document is an example of a Memorandum of Understanding between a state health department and a wastewater treatment plant. This document does not constitute legal advice. If you wish to implement an agreement regarding wastewater monitoring, you should consult with an attorney and obtain legal advice specific to your needs.

    The purpose of this Memorandum of Understanding is to set forth the terms and conditions, scope of work, and responsibilities of the parties associated with their collaboration on wastewater surveillance.  Download Word document

NWSS Communities of Practice

Communities of practice (CoP) are groups of professionals in various wastewater surveillance fields that generally meet on a monthly basis.

Centers for Disease Control and Prevention (CDC) Logo

Health Department Community of Practice

Hosted by The Centers for Disease Control and Prevention (CDC) NWSS team

This CoP is a forum to allow state wastewater surveillance programs to receive updates from the CDC NWSS team, share ongoing work related to wastewater surveillance, and have direct access to leaders and peers in the field of wastewater surveillance. The NWSS health department CoP call is held on the fourth Thursday of each month from 1:00 - 2:00 pm ET. If you are interested in joining the NWSS CoP call, please email NWSS@cdc.gov.

 Water Environment Federation Logo

Utility Community of Practice

Hosted by the Water Environment Federation

The NWSS Utility CoP is a collaborative for promoting review, synthesis, and sharing of lessons learned among wastewater utilities to accelerate implementation of wastewater surveillance and participation in the NWSS to support public health decision making. The Utility CoP is held on the third Thursday of each month from 3:00 - 4:00 pm ET. If you are interested in joining the Utility CoP call, please email nwbe@wef.org, or visit their website to learn more and fill out the request form.
