DRACUT — Amid growing concerns about the effect that toxic vapors from the Navy Yard Mills complex in Dracut may have had on the health of hundreds of children who honed their baseball skills at the Future Stars Sports Training Center, the Environmental Protection Agency is giving parents an opportunity to question environmental officials and pediatricians from Boston Children’s Hospital.

The EPA Sunday is holding two informational sessions — at 10:30 a.m. and 1:30 p.m. — at the Central Fire Station in Dracut to discuss the site, which was found earlier this year to have unacceptably high levels of trichloroethylene and tetrachloroethylene, which are nonflammable, colorless chemical solvents commonly used to degrease metal parts.
