Seems like little good idea if testing is dropping off.
ESR seems to have gone silent since May
ESR scientists are setting up a project to gain new insights in to Coronavirus by analysing wastewater samples.
"The aim of the project is to detect and quantify SARS-CoV-2 (the virus that causes COVID-19) in wastewater and to better understand the role environmental monitoring can have in monitoring COVID-19 over time.
Sewage samples from known COVID-19 cluster areas have been collected and frozen while testing methodologies and protocols are established
When ready to carry out the testing, scientists will extract RNA from concentrated sewage samples - using the PCR method to amplify the samples they’ll then look for genes associated with Coronavirus.
If detected, ESR Chief Scientist, Dr Brett Cowan says the value will be in monitoring the distribution and prevalence of COVID-19 in the weeks, months and years ahead.
'By detecting and monitoring Coronavirus in wastewater we could potentially see how effective eradication is, gauge changes in different regions as well as better understand the patterns of community transmission,' he says."
Here's their ESR Covid web page updates, which seems stale
