Updated: 11/26/24
Where do we sample?
The map showcases where our sites are spread throughout the county. All sites are a representative sample of the communities on the waste system. We select varying areas across the county to help build an understanding of disease dynamics in Ottawa County in order to aid in public health efforts.

COVID-19
Throughout Ottawa County (O1 and A4), the wastewater viral activity level for COVID-19 is a minimal concern.
Minimal Concern
Minimal Concern
Potential Concern
Cause for Concern
The visualizations below display virus levels in wastewater over time, measured in gene copies/100mL of sample. A color-coded scale on the right indicates the risk level tied to the gene copies/100 mL for Ottawa County sites. The virus levels help us better understand the amount of COVID-19 disease in the community when used with other existing data like clinical positivity rates, hospital rates, and vaccination rates. To check the viral concentrations for a specific location, click the site ID name within the visual below.
Influenza
The visualizations below display virus levels for both influenza A and B in wastewater over time, measured in gene copies/100mL of sample. The virus levels help us understand the amount of influenza disease in the community when used with other existing data like clinical positivity rates and hospital rates. To check the viral concentrations for a specific location, click the site ID name within the visual below.
RSV
The visualization below displays virus levels in wastewater over time, measured in gene copies/100mL of sample. The virus levels help us understand the amount of RSV disease in the community when used with other existing data like clinical positivity rates, hospital rates, and vaccination rates. To check the viral concentrations for a specific location, click the site ID name within the visual below.
Norovirus
The visualizations below display virus levels for both dominant versions of norovirus in wastewater over time, measured in gene copies/100mL of sample. Norovirus levels are naturally much higher than respiratory viruses due to how noroviruses reproduce and spread. The virus levels help us understand the amount of norovirus disease in the community when used with other existing data like clinical positivity rates and hospital rates.
