The research, published in ACS’ journal Environmental Science & Technology, says the number of people without access to is almost double the previous estimate.

Jamie Bartram and colleagues explain that the current definition of “improved sanitation” focuses on separating humans from human excrement, but does not include treating that sewage or other measures to prevent it from contaminating rivers, lakes and oceans.
