Levels and treatment options for enteric and antibiotic resistant bacteria in sewage from Sisimiut, Greenland
Sewage treatment in Arctic towns is inadequate. Sewage contains pathogenic microorganisms, parasites, antibiotic resistant bacteria, and toxic compounds. Discharging of untreated sewage can thus have a negative effect on people’s health and the aquatic environment in the receiving water bodies. Conv...
