Should wastewater workers take extra precautions to protect themselves from the virus that causes COVID-19?
section_content: Recently, the virus that causes COVID-19 has been found in untreated
wastewater. While data are limited, there is no information to date that
anyone has become sick with COVID-19 because of exposure to wastewater.
Standard practices associated with wastewater treatment plant operations
should be sufficient to protect wastewater workers from the virus that causes
COVID-19. These standard practices can include engineering and administrative
controls, hygiene precautions, specific safe work practices, and personal
protective equipment
(PPE)
normally required when handling untreated wastewater. No additional
COVID-19–specific protections are recommended for workers involved in
wastewater management, including those at wastewater treatment facilities.

Can the COVID-19 virus spread through sewerage systems?
section_content: The virus that causes COVID-19 has been found in untreated wastewater.
Researchers do not know whether this virus can cause disease if a person is
exposed to untreated wastewater or sewerage systems. There is no evidence to
date that this has occurred. At this time, the risk of transmission of the
virus that causes COVID-19 through properly designed and maintained sewerage
systems is thought to be low.

Reviewer feedback on this answer:
The answer gives as much data as possible.  It states that the virus has been found in wastewater.
This answers the question directly. This answer provides known information on Covid-19 found in untreated wastewater and the risk of transmission through the untreated wastewater or sewerage systems.

Can the virus that causes COVID-19 spread through drinking water?
section_content: The virus that causes COVID-19 has not been detected in drinking water.
Conventional water treatment methods that use filtration and disinfection,
such as those in most municipal drinking water systems, should remove or
inactivate the virus that causes COVID-19.

Reviewer feedback on this answer:
The answer directly states that the virus doesn't travel through water.
This information is irrelevant to the question. It explains about Covid-19 in drinking water and the question is asking about Covid-19 spread through untreated water.
