A New York State Department of Health study, completed in May 2007, indicated that no vapor was coming from the spill into homes. The Environmental Protection Agency's (EPA) "Newtown Creek/Greenpoint Oil Spill Study Brooklyn, New York" states that vapor concentrations in "some commercial establishments" were found "above the Upper Explosive Limit". The study also said, "A review of the data collected by the NYSDEC shows that, in general, chemicals were detected at all locations in each home, but not in a pattern that would typically represent a vapor intrusion phenomenon."
