In this week's water and wastewater news, residents in two Louisiana parishes are warned about a brain-eating amoeba in their water systems; and scientists predict tardigrades will be the last creatures on Earth.


Two of Louisiana’s water systems have tested positive for Naegleria fowleri, an amoeba known colloquially as the brain-eating amoeba, according to the state’s department of health.

Residents in Terrebonne Parish’s Schriever system and Ouachita Parish’s North Monroe system have been advised to take precautions to mitigate the risk of infection.

Both water systems were asked to convert to free chlorine disinfection for the next 60 days in order to kill the amoeba.

Researchers say the water bears will long outlive human being on our planet, and is the ultimate survivor as it can live for 30 years without food or water and withstands temperatures near absolute zero and up to 300 degrees Fahrenheit.

“A lot of previous work has focused on doomsday scenarios on Earth — astrophysical events like supernovae that could wipe out the human race,” said Dr. David Sloan of Oxford University. “Our study instead considered the hardiest species – the tardigrade.”
