OHA releases COVID-19 Wastewater monitoring data

October 27, 2020

Today, OHA is beginning to display data related to its statewide COVID-19 wastewater monitoring project. The data shows where the virus is detected in small- to medium-sized communities around the state.

Currently there are 29 communities participating on the project. A map shows if COVID-19 is “detected” or “not detected” in a community. It is important to note that if the virus was “not detected”, it does not mean that the community is free of COVID-19. Instead, it means that the virus may still be present in the area but below detection levels.

The monitoring serves as an “early warning” system to tell us if COVID-19 is spreading silently in communities. It is meant to help public officials try to prevent potential outbreaks or, if necessary, move resources to a community. OHA launched the project in the early fall with funding from the CDC.
