Table 2.

Modelled scenarios of SARS-CoV-2 RNA loading in the Camel and Conwy estuaries during spring-summer 2020. Note: each scenario was run twice with different decay rates; T₉₀ = 24 h and T₉₀ =35 ​days (840 h).

Simulation		Infection timeseries $\mathit{I}(\mathit{t})$	RNA load of Infected person with positive faeces (copies/day)	2 Log10 Treatment	Number of effluent discharge locations (Camel, Conwy)	Catchment Population (Camel; Conwy)
1	Best Estimate Loading	ONS	$1.36\times {10}^6$	Yes	3,2	59,579; 11,506
2	IMHE infections	IMHE	$1.36\times {10}^6$	Yes	3,2	59,579; 11,506
3	Worse Case Loading	ONS	$6.80\times {10}^6$	Yes	3,2	59,579; 11,506.
4	Best Estimate Untreated	ONS	$1.36\times {10}^6$	No	3,2	59,579; 11,506
5	Worse Case Untreated	ONS	$6.80\times {10}^6$	No	3,2	59,579; 11,506
6	Equal loadings Treated	ONS	$1.36\times {10}^6$	Yes	1,1	59,579; 59,579
7	Equal loadings Untreated	ONS	$1.36\times {10}^6$	No	1,1	59,579; 59,579
