Note: The values in blank “-” mean that within Ecuador the points studied do not have Wastewater Treatment Plant (WWTP), while the values with "NF" mean that the information were not found.
1
The values in USA come from McCormick et al. (2016).
2
The values in Germany come from Mani et al. (2015).
3
The values for habitants and drainage area in other river worldwide come from each wastewater system official site.
