They convinced the school district to re-surface an athletic field with cork, instead of crumb rubber, which is made out of old tires.

On Friday KTVU learned the state has launched a new $3 million project to evaluate the safety of the material.

The study will analyze both new and existing crumb rubber fields, and will also take a look at the air quality above indoor, and outdoor synthetic turf fields and playground mats.
