Follow up testing of the Crookwell Sewage Treatment Plant has returned a negative result for COVID-19 fragments.
A previous test conducted by the Upper Lachlan Shire Council on behalf of NSW Health in late September detected COVID-19 fragments, but further testing has been unable to replicate the result.
Council director of environment and planning said the result was good news.
"These fragments don't just relate to residents but can come from visitors and people passing through the Shire," she said.
"A negative result indicates there are no indications of current COVID cases in Crookwell, but that's not a signal to stop taking precautions.
"Things can turn around very quickly and with COVID cases located adjacent to the shire, it remains important to follow appropriate health and safety guidelines and to get tested if you show any symptoms, or if you are returning from other areas.
The council will continue a weekly sampling regime in Crookwell until advised by the Sewage Surveillance Program to stop, or to test elsewhere in the shire.
Testing sewage can help track infections in the community and provide early warning of an increase in infections. These tests provide data to support NSW Health's response to COVID-19.
An infected person can shed virus in their faeces even if they do not have any symptoms, and shedding can continue for several weeks after they are no longer infectious.
