District’s environmental consultants took 26 samples earlier this week; results to be reviewed by New York State Department of Health
Northport-East Northport school officials and parents are awaiting the results of the latest
Middle School K-wing air quality samples prior to the school’s reopening next week.
The district’s environmental consultant firm J.C. Broderick & Associates Inc. took 26 air samples throughout the K-Wing of Northport Middle School earlier this week to see if issues with gasoline fumes have been fully resolved after extensive summer renovations.
“The question I have been asked is are we going to test before we reopen the K-Wing,” Superintendent Robert Banzer said. “The answer is yes.”

Edward McGuire, of J.C. Broderick & Associates, said the testing consisted of placing two air sampling cannisters in every single classroom and office space, two in the hallway, and two in the warehouse space beneath the wing, which was the previous site of chemical storage, to see what level of volatile organic compounds, known as VOCs or fumes, are present. In addition, two cannisters were placed outside the building to represent the ambient air that is brought into the school building via the ventilation systems.
“It is the créme de la créme of VOC sampling,” the consultants said. “There is no better methodology.”
The cannisters were placed at varying heights 3 to 5 feet off the ground in each location, according to McGuire, meant to replicate the typical breathing zone of a seated or standing person within the space. Each room was independently sealed off before air samples were collected for a continuous eight-hour period while the newly installed rooftop ventilation systems ran, McGuire said, meant to replicate “typical occupancy conditions.”
Brandon Weisberg, project superintendent for district contractors Park East Construction, said the K-Wing classrooms were ripped down to the studs this summer. New plumbing was installed, fire stoppers sealed, and a special heavy-duty vapor barrier applied on the concrete subsurface between the underground warehouse storage and K-Wing to prevent any fumes from penetrating into the air, according to Weisberg. The district also had new rooftop heating, air conditioning and ventilation units installed while also sealing the older ground-level passages with concrete.
The environmental consultants said their staff has worked with the district’s contractors to obtain safety data sheets for each material used in renovating the K-Wing this summer, providing a list of any potentially hazardous chemicals contained in each product. McGuire said this data will be used to help analyze the air samples and potentially used to identify the source of any abnormally high fumes or airborne chemicals found during the sampling.
“The sensitivity of the analysis will always find VOCs in the air,” McGuire said. “Our expectations are also a little higher because we know everything is brand new.”

The consultants were asked to explain during a presentation at an Aug. 23 board of education meeting that any smell in the K-Wing could be similar to the odors detected by new car owners when they sit inside the vehicle.
J.C. Broderick said they will be doing a two-part comparison of the air samples taken. The first part will be a report on the ambient levels of each VOC detected, while the second phase will examine the levels found against healthy safety guidelines established by New York State Department of Health. McGuire said the standards being used will be compared against the U.S. Environmental Protection Agency’s dose concentration guidelines, which consider different levels for sensitive populations, such as young children.
The results of the air quality testing were expected to be received within approximately 72 hours of the end of sample collection, or 48 hours after the cannisters were delivered to the laboratory. The final report will be sent to New York State Department of Health for its review prior to the classrooms being reopened to student and staff use.
The results were not yet available as of noon Aug. 29, according to the superintendent.
Banzer assured residents the district has repurposed the old warehouse space as a dry storage for “paper goods” and other such things.
“There are no chemicals stored down there, all that was eliminated last year,” he said.
