New York: Marc Johnson saw trouble in the water. Johnson, a virus expert at the University of Missouri, had spent much of 2020 studying sewage, collecting wastewater from all over the state and analysing it for fragments of the coronavirus. People with COVID-19 shed the virus in their stool, and as the coronavirus spread throughout Missouri, more and more of it began to appear in the state’s wastewater.
In January, Johnson spotted something new in his water samples: traces of B.1.1.7, a more contagious variant that was first detected in Britain. Officially, the state had no confirmed cases of B.1.1.7, but the wastewater suggested that the variant had arrived. By the end of the month, the B.1.1.7 levels in Johnson’s water samples had risen sharply, and in early February, the state finally found its first case. It has since found hundreds more.
From the Wastewater Drain, Solid Pandemic Data
The coronavirus could turn sewage surveillance into a mainstream public health practice.

Comments Off on Salt Pollution Threatens Human Water Security
BLACKSBURG, Virginia, April 22, 2021 (ENS) – “Inland freshwater salt pollution is rising nationwide and worldwide, and we investigated the potential conflict between managing freshwater salt pollution and the sustainable practice of increasing water supply through the addition of highly treated wastewater to surface waters and groundwaters,” said Stanley Grant, professor of civil and environmental engineering in the Virginia Tech College of Engineering.
“If we don’t figure out how to reverse this trend of salt pollution soon, it may become one of our nation’s top environmental challenges.” Grant and his collaborators have published their findings in the journal “Nature Sustainability.”
