Long-chain perfluorinated chemicals contaminate millions of Americans’ drinking water. These compounds are a legacy of industrial pollution and the use of firefighting foam at military bases and airports; they persist in the environment because of their strong carbon-fluorine bonds. Now scientists have designed a cross-linked polymer that might more effectively remove one of the more prevalent and harmful of these compounds, . . .
