Anne Arundel County fire and rescue crews are treating 35 people that were overcome by pool chemicals at YMCA Camp Letts near Edgewater.

Two remain at Johns Hopkins Children's Center in Baltimore in the pediatric intensive care unit where they were are being treated for burns to their respiratory tract.

Crews responded to the scene at 9:50 a.m. late Wednesday morning after getting a 911 call involving the YMCA Center.

Anne Arundel County Fire Department officials say four adults and 31 children were overcome by muriatic acid and sodium hypochlorite, causing symptoms of nausea and vomiting.

Four of the children were taken to Hopkins Children's Hospital in Baltimore. Others were taken to Anne Arundel Medical Center, Baltimore Washington Medical Center and Queen Anne's Medical Center.

An investigation is under way to identify the cause of the chemical leak, however a spokeswoman for the YMCA believed pump malfunctioned due to Tuesday's thunderstorms.
