TL;DR: Sewer asset management gained momentum and importance in recent years due to economic considerations, since infrastructure maintenance and rehabilitation directly represent major investments as discussed by the authors. But it is still a relatively new area.

TL;DR: New/improved software tools coupled with the current high computational capacity have enabled the application of integrated modelling to several practical cases and advancements in monitoring water quantity and quality have been substantial and now allow the collecting of data in sufficient quality and quantity to permit using integrated models for real-time applications too.

TL;DR: Despite large reductions in nitrogen and phosphorus discharge to freshwater systems, bluegreen algae blooms occur more frequently, which is the result of the accepted notion among policy makers that eutrophication can be reduced or limited by nitrogen or phosphorus limitation.

TL;DR: This discussion attempts to address the question as to whether there is an increase in uncertainty by linking these models or if a compensation effect could take place and that overall uncertainty in key water quality parameters actually decreases.

TL;DR: In this paper, the authors provide the first evidence that passive samplers can be used to detect SARS-CoV-2 in wastewater from populations with low prevalence of active COVID-19 infections (0.034 to 0.34 per 10,000), demonstrating their ability for early detection of infections at three different scales (lot, suburb, and city).
