After residents in Gowanus voiced concerns over potential air contamination from construction at the Superfund Gowanus Canal site, the area EPA office helped show residents how a new mobile unit would be monitoring air quality until the end of March.

The EPA's new Trace Atmospheric Gas Analyzer, or TAGA bus, will be looking at the air quality in the area, tracking for the chemical naphthalene, known as a volatile organic compound and a by-product of the tainted coal that is being contained at the Superfund site.

On Monday, residents got to take a look inside and meet the team that will be tracking those measures and sharing the data with local officials and the Superfund project.

"The parameters are drawn so that actions are taken at levels far below any potential effects, so it that action level is reached, that means that folks at the site can take mitigating measures to prevent odor," said EPA community involvement coordinator Natalie Loney, who says that the storage tanks construction prompted their response.

Residents tell News 12 they were impressed with the transparency and technology, but remain split on if the monitoring will have an impact.

"Seeing it first hand, I'm glad there is real effort real energy being made to address this," said resident Gary Francis.

"I'm reassured. I'm glad they're monitoring but at the same time I don't think they will send an alert to me if it's too high- or tell me if it is getting in my home," said resident Lauren Dalban.

According to Loney, a separate indoor air quality assessment from the NYC DEP has also been commissioned for the area.

Others believe the testing, and contamination and clean up should have happened prior to the area's rapid development in recent years.

"We want as much clean up, not just containment as we can get, I'm very concerned that this monitoring is good but it is too little too late, because now we are measuring just how much chemicals people can take, while we are looking to build housing for thousands," said resident Glenn Kelly.
