One Air Quality Report on the Martin Tower demolition (70)

(70th in a series on Martin Tower)

Vertex Martin Tower results

Here linked are air quality test results from the developer’s testing agent.

Conclusion:
Air 5ampling results revealed no detectable concentration5 of asbestos or lead. However, two air samples for asbestos content could not be analyzed due to overloading of particulate. PM monitoring revealed no remarkable concentrations in three of the sampling locations. The PM monitoring station positioned northeast of the building within the fence line near the Eaton Ave/ Schoenersville Road egress was visibly coated with debris following the implosion. Data from this northeast sampling station indicates a significant spike of PM for less than a half hour after the implosion, subsequently, the PM concentrations generally went back to normal or slightly above normal readings.
If you should have any questions or require further information, please do not hesitate to contact me.
Sincerely,
The Vertex Companies, Inc.

Test results from the Pennsylvania Department of Environmental Protection will need to be obtained with a Right-to-Know request when they become available.

  1. The pollution didn’t vanish; I suspect the spike means it moved on to the nearby residential area

  2. It sure would be nice if a plain English explanation were given concerning the technical information.

  3. Oh Geez. They didn’t even test for respirable silica which is what caused thousands of horrible cancer deaths after the collapse of the WTC. As for the “However, two air samples for asbestos content could not be analyzed due to overloading of particulate. ” Overloading is why they didn’t have air monitoring reports for the “8,000” other projects they imploded. Why not just say what was in the dust not what wasn’t in the dust?

  4. Gadfly,

    This summary does not present the results in a very helpful way. It would be nice to know the range of concentrations by particle size per monitor. To say that during the implosion maximum concentrations ranged from 9.3 to 33,625 micrograms per cubic meter of air for particles with an average diameter of between .31 and .91 micrometers does not allow us to put the results in the context of any meaningful ambient air regulatory standards, which designate safe levels for particles that measure 2.5 (or 10) micrometers. Assuming the presented numbers were averaged across all four monitors in very different locations, we don’t know where the fallout was worst, and what amount of particulate might have fallen into the creek or an area where people live (vs. what looks like a parking lot on their map).

    The results suggest that one PM monitor was inundated with particulate so I guess we can assume that location was hit the worst, but what were the specific numbers associated with that location? Also, as Mr. Lopez notes, telling us what was not in the air is not the same thing as telling us what was in the air. I guess these data show that the demolition company was not lying when it said it had removed all the asbestos and lead paint, but we already had reason to believe that was true because the DEP went and checked their work.Did they even bother to do a chemical analysis to identify other toxins? I guess we’ll have to wait for the DEP to tell us what else might have been in the air, assuming their monitors were not inundated with so much dust as to also become “overloaded.”

    Can we please see the original data as gathered by each monitor? What is here simply conceals any meaningful variation in exposure by location to either homeowners or aquatic resources. If this is all we are going to get, it merely confirms that the developers of this site have no interest in being genuinely responsive to public concerns. Of course, if you don’t live in this community and got the mayor to work out a way for you to make a bundle selling the property, why would you care about the concerns of anyone in the neighborhood? This is disappointing but of course it is no surprise.

  5. The PM didn’t disappear after a half an hour; as Mr. Crownfield said, it blew away. But not just into not nearby neighborhoods. Into faraway ones, too! We could taste the dust on our lips in the south side well into the late afternoon hours (up until the rain started), even when we were not in the direction of the prevailing winds!

    When we drove by the site two days ago and it was slightly breezy, the same thing happened: you could taste the cement (or is it concrete?) dust on your lips! They are telling us that is normal? What does “normal” mean? What does “remarkable” mean? If you ask me, or the nearby neighbors, it has all been pretty remarkable.
