A high school student from New York has developed an inexpensive solution to remove arsenic from drinking water, a problem that threatens over 200 million people worldwide. The modified teabag design has passed peer review and could provide safe drinking water for just 7 cents per liter.

Why it matters

Arsenic contamination in drinking water is a major global health crisis, causing disability and death for millions who lack access to expensive water treatment infrastructure. This student-developed solution offers a scalable, low-cost approach to make clean water more accessible.

The details

The student's design involves engineering simple, low-cost materials into a modified teabag that can effectively filter out arsenic from drinking water. Careful reuse of the teabag could further reduce the cost to just 7 cents per liter of treated water.

  • The student developed the solution while in high school.
  • The design has now passed peer review.
