Glow-in-the-dark tampons could show us where sewage is
accidentally being leaked into rivers.
The novel technique is being proposed by a team from the
University of Sheffield’s Faculty of Engineering, which
has proven its theory by attaching tampons to 16 surface
water outlets that run into Sheffield’s rivers and
streams. When the tampons glowed under ultraviolet light, the team
knew waste water was present at the outlet.
