    dct:description """The **sewage treatment works****dataset** 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.""" ;
