As sea levels rise, septic waste may leak into coastal homes
Abstract
The global consequences of sea level rise - flooding, destruction of wetlands habitat, increased storm surges - are devastating. Millions of people in coastal communities could find raw sewage oozing into their homes. People living in coastal areas often have personal septic tanks designed to treat wastewater. If this is news to you, here's a little septic tank 101. "Not only will the septic tank stop working, but if groundwater levels rise to the surface, groundwater that has been in contact with septic tank sewage could end up in people's homes, backyards or on the street." Not only is this totally gross, but it can ruin the drinking water supply. Worst case, backed up septic systems might lead to cholera and dysentery, according to Bierkens. What can coastal communities do to stay safe? Invest in their sewage systems to make sure they don't leak.
