Introducing Quadrant Wastewater Surveillance

Wastewater surveillance acts as an early warning system for COVID-19 by detecting the presence of viral RNA shed into the sewer systems. Analysis of wastewater samples will provide local health officials and policymakers with early indications and information regarding the presence and preponderance of COVID-19 infections in these communities.

Why sample wastewater

Why sample wastewater

Allows for large regions to be tested for the presence of viral RNA

Identifies early trends of transmission in community 4-7 days before symptoms appear

Provides local health officials and policymakers with early indications and information on infection rates in their communities

Prompts early targeted interventions

How it works


Samples are collected from influent lines close to the source


Quantifies SARS-CoV-2 viral load in sample


Qualitatively identifies trends in SARS-CoV-2 infections


Standardizes samples using crAssphage, a common bacteriophage found in human stool


Identifies trends of increasing or decreasing transmission of SARS-CoV-2


How effective

Highly sensitive, can detect 1 infected person in a population of 10,000


Who benefits

Communities, residential buildings, institutions and manufacturing facilities can all benefit from wastewater testing

Sample and Transport Protocol

Collect samples from an influent water stream closest to the source


Samples should be collected using a composite water sampler


Place samples in a 250ml capped bottle


Samples should be received within 24 hours of collection


Once samples are received an analytical report will be emailed within 2 business days
