The Narragansett Bay Commission has been approved for participation in the COVID-19 study conducted by the US Department of Health and Human Services (HHS) and the US Centers for Disease Control and Prevention (CDC).

The study quickly monitors 100 million people across the United States through wastewater monitoring to monitor COVID-19 epidemics and identifies best practices for national wastewater SARS-CoV-2 assessments and subsequent data analysis. The purpose is that.

Questions about coronavirus transmission through wastewater began in May 2020, when the World Health Organization began to raise questions.

In October, MIT reported that the university began piloting a wastewater test program this semester as a new tool to keep the campus community safe.

“In the fall semester project, wastewater from seven buildings on campus will be tested daily for SARS-CoV-2, the virus that causes COVID-19. This project is capable of wastewater testing. Designed to determine if it is an effective early warning system for the outbreak of COVID-19 on campus, in clinical trials, contact tracking, and other means, as well as in the laboratory’s response to pandemics. It is valued as a complementary tool, “MIT reported.

Amount of virus in water

NBC’s Bucklin Point wastewater treatment facility in East Providence is participating in Phase I of the study. In this phase, raw wastewater inflows are tested twice a week for 6 weeks. Phase I assesses 10% of the US population through wastewater monitoring. Monitoring began on December 27, 2020.

In the second phase, we will register additional processing plants to achieve our goal of monitoring 30% of the US population. All data is edited by HHS and relayed to the community. It aims to return data as soon as possible so that the local health department can make quick and practical decisions.

“Wastewater treatment has always been an integral part of public health, protecting citizens from diseases and epidemics such as dysentery and cholera,” said NBC Chairman Vincent Mesorella. “Re-contribution to the COVID battle is a natural advancement of our public health mission. We are very proud to be able to participate in this study, which will provide valuable data to our leaders during this difficult time. think.”

Papers published in Nature “The health risks of COVID-19 due to water-borne infections may be greater than initially expected, and wastewater needs to be further studied as a potential route for COVID-19 infection. SARS-CoV-2 RNA is in the wastewater system. Evidence Existence In current pandemics, along with the high infectivity of SARS-CoV-2, a large number of infected individuals may present new challenges in wastewater treatment, requiring a future assessment of the risk of infection from wastewater reuse. The risk may be expected to be highest in densely populated areas that are directly exposed to aerosolated wastewater and in areas that lack proper wastewater collection, treatment and disinfection. There is. “

“Extensive research on the frequency of detecting infectious SARS-CoV-2 in wastewater is urgently needed to obtain:

(1) Important information about raw wastewater, treated wastewater, and the abundance of viruses in the receiving environment. You can use it to generate a quantitative risk assessment.

(2) Information on removal efficiency by wastewater treatment trains.

(3) Disinfection requirements according to virus load and infection via WWTP to completely remove SARS-CoV-2 for wastewater reuse. (4) Epidemic Surveillance of Policymakers on the Outbreak, Scope, and Epidemic of the COVID-19 Pandemic Within the Community ”, a report released in August wrote.
