COVID-19 in Wastewater Surveillance

Over the past two years, researchers have turned to wastewater to find out more about the trajectory of the COVID-19 pandemic.

In September of 2020 the CDC developed the National Wastewater Surveillance System (NWSS) to help monitor and better understand the spread of COVID-19 throughout communities. The NWSS works directly with public health departments to track the presence of the SARS-CoV-2 virus in the wastewater of communities across the country. They are able to do this because humans infected with the SARS-CoV-2 virus shed the virus in their feces making it detectable within community wastewater systems. The CDC has been able to gather a large amount of data because 80 percent of households in the United States are served by municipal wastewater collection systems. Wastewater surveillance programs have been implemented across the country in places like Utah, Washington D.C., Massachusetts, Connecticut, and Illinois. Programs have also been implemented internationally. 

Wastewater surveillance technology has proven to be very beneficial to communities because it is able to detect the virus even before people start showing symptoms. This is helpful because once health departments are aware, communities can immediately take stricter precautions to prevent the spread of the virus. You can stay up to date on the presence of COVID-19 in your community by checking the COVID Data Tracker which provides regularly updated information on the presence of SARS-CoV-2 levels in wastewater at testing sites across the country. 

Outstanding Webinars: Plan, Promote, and Present

The pandemic changed the game for online learning, with webinars becoming a staple for many organizations.

The Benefits of Drones in the Water Industry

Unmanned aircraft systems (UAS), also known as drones, have slowly made their way into various parts of society, including the water sector. They offer a more accessible and affordable way for water utility managers to survey their systems. They also offer plant managers the ability to collect detailed information about the status of their utility through aerial photos and videos. 

The greatest benefits of drones are that they are highly efficient while still being relatively inexpensive. Drones can be used to collect data ranging from updating processes to designing additions, as well as building changes, maintenance, and demolition. 

Some water companies in France are even using drones to inspect sewer operations. They are also being used in New Zealand as part of a water quality monitoring project. Drones are being used in Ireland to survey problems before they arise and catch unlawful dumping that would eventually become issues for wastewater treatment workers to handle. Drones have proven to be especially helpful in the wastewater industry by increasing worker safety, reducing energy consumption, streamlining planning, improving insight and education, and efficiently collecting samples.
