Effluent wastewater samples were collected from a hospital within the catchment area of Bath. Samples were collected over five consecutive days (5 th -9 th August 2019) from a hospital outlet that accounts for approximately 60% of the total wastewater originating from this hospital. This is a medium-sized hospital (>700 beds and a catchment of 500,000 people). Between the hospital and the WWTP serving Bath is 10 km of sewer pipeline. Hospital effluent samples were collected by 24 h composite samplers set to time-proportional, with 50 mL collected every 15 minutes. Collected samples were transported on ice to the laboratory to be processed (< 1 h).
