section_headers: COVID-19 and Water
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:
Answers question specifically as to the fact that COVID-19 has been found in untreated wastewater and specifies that it is not known if a person can get sick from being exposed to it.
The first sentence of the response answers the question being asked directly. It does a good job offering some additional supporting details. Solid answer

section_headers: Waste Management
What do waste management companies need to know about wastewater and sewage coming from a healthcare facility or community setting with either a known COVID-19 patient or person under investigation (PUI)?
section_content: Waste generated in the care of PUIs or patients with confirmed COVID-19 does
not present additional considerations for wastewater disinfection in the
United States. Coronaviruses are susceptible to the same disinfection
conditions in community and healthcare settings as other viruses, so current
disinfection conditions in wastewater treatment facilities are expected to be
sufficient. This includes conditions for practices such as oxidation with
hypochlorite (i.e., chlorine bleach) and peracetic acid, as well as
inactivation using UV irradiation.

Reviewer feedback on this answer:
Answer does not specify if COVID-19 is found in waste or wastewater but does mention that disinfection in current wastewater facilities should be good enough to eliminate the virus if it is present.
This is a pretty good answer that touches on how waste water doesn't present more danger to anyone as normal treatment is expected to be sufficient against COVID

page_title: Clinical Questions about COVID-19: Questions and Answers
section_headers: Waste Management
Do wastewater and sewage workers need any additional protection when handling untreated waste from healthcare or community setting with either a known COVID-19 patient or PUI?
section_content: Wastewater workers should use standard practices including basic hygiene
precautions and
wear the recommended
PPE as
prescribed for their current work tasks when handling untreated waste. There
is no evidence to suggest that employees of wastewater plants need any
additional protections in relation to COVID-19.

Reviewer feedback on this answer:
Answer mentions standard hygiene and PPE but does not mention whether COVID-19 is found in wastewater or not.
This doesn't really answer the question, but maybe in a roundabout way by suggesting wastewater workers don't need additional protections. Should be more clear in its response.
