There are two main types of gravity sewers, sanitary and combined. Sanitary sewers only treat the ...
The global 'resistome' based on sewage-based monitoring [47] Gene-sharing network between bacterial genera [47] In 2022, genomic epidemiologists reported results from a global survey of antimicrobial resistance (AMR) via genomic wastewater-based epidemiology, finding large regional variations, providing maps, and suggesting resistance genes are ...
Newsy learned New York State, for example, suspended its sewage surveillance pilot after a month in part because of an equipment shortage. As a result, testing stopped in four places including ...

The main parameters in sewage that are measured to assess the sewage strength or quality as well as treatment options include: solids, indicators of organic matter, nitrogen, phosphorus, indicators of fecal contamination. [1]: 33 Tests selected vary with the intended use or discharge location. Tests can measure physical, chemical, and ...
