National Wastewater Surveillance System (NWSS)

Wastewater surveillance is an important public health tool to track the spread of diseases in communities. Wastewater surveillance data can help local public health agencies identify outbreak trends early, direct prevention efforts to where they are most needed, and provide additional insight into disease spread that complements other public health surveillance data. CDC developed the National Wastewater Surveillance System (NWSS) to coordinate and build the nation’s capacity to track the presence of germs in wastewater.
