The sewage treatment worksdataset includes norovirus levels,
ammonia concentrations and orthophosphate concentrations in wastewater from
3,232 samples and their associated metadata collected for the Environmental
Monitoring for Health Protection (EMHP) programme between May 2021 and March
2022 from the untreated influent of 152 sewage treatment works across England.
The samples are a subset of samples that were originally collected and
analysed for SARS-CoV-2.
The network dataset includes all of the norovirus levels, ammonia
concentrations and orthophosphate concentrations in wastewater from 220
samples and their associated metadata collected for the Environmental
Monitoring for Health Protection (EMHP) programme between May 2021 and March
2022 from 11 sewerage network sites across England. "NETWORK" sites were
located further upstream of the sewershed than the sewage treatment works
(STWs). Network sites were typically used during the COVID-19 pandemic to get
better spatially resolved data than was possible using sewage works alone.
