Notes:
Samples taken near bridges contain "Bridge" in the sampling site name and B at the end of the acronym. Conversely, samples lacking "Bridge" in the sampling site name are not taken near bridges.
For the ESBL and carbapenemaseproducing bacteria, we selectedonly a few sites due to lack of resources. These missing data are recorded as NA.
For water samples, values are per volume of water, but for sediment samples, values are per dry mass or per mass of Organic Matter (OM), measured as Volatile Solids (VS). For details, see the Units tab.
Samples which showed 0 colonies on undiluted duplicate plates, each with 0.1 mL plated volume, were below detection limit. Values have been imputed in the following way.
Two replicates of undiluted samples were plated (0.1 mL per plate), so the total volume plated was 0.2 mL
Counts of zero CFUs on both replicate plates have been replaced according to the calculations in the LoD file, in brief:	
Replace counts of 0 with ~0.6 CFU/mL-counted, in this case ~0.6 CFU/0.2 mL = ~3 CFU/mL
0.58	CFU/volume counted
2.91	Divide above figure by mL counted
0.46	Log10 of above figure
