Portland district can reopen artificial-turf field

The artificial turf field at Rieke Elementary School in Portland, Ore., has been reopened to kids of all ages. Since September, when school district tests found traces of lead, the field had been off limits to users younger than 11. The lead levels were within safety ranges set by the U.S. Consumer Product Safety Commission for turf fields, but exceeded more general recommendations for lead in soil set by the federal Centers for Disease Control and Prevention. The district and the Bureau of Parks and Recreation opted to limit access to the field until additional tests were completed.
