NEWARK, N.J. (AP) — The levels of harmful contaminants at Superstorm Sandy cleanup sites in New York and New Jersey have so far not exceeded federal workplace exposure limits, officials said Wednesday.

The Occupational Safety and Health Administration tested dozens of cleanup sites, measuring worker exposure to toxic substances. The agency fanned out to workplaces and debris sites ranging from beaches to landfills, testing for airborne contaminants and taking samples from debris and storm water.
