In response to a request from the Mayor of Springfield, Missouri, Dr. Barbara Mahler and Dr. Peter VanMetre of the United States Geological Survey attended a special session of the Council. While the video is lengthy (90 minutes plus), it is one of the most understandable presentations on the problem with coal tar pavement sealants to date.
Here are some of the highlights:
* What are PAH's. This really is a great explanation in simple terms.
* Technical rigor and independent research approach of the USGS
* Historical perspective on the longevity of pollutants after their use is reduced or eliminated
* Explanation of the 40 lakes study that found that a significant percentage of PAH pollution at locations around the country are caused by coal tar pavement sealants.

So, it has happened again. Another documented case of runoff pollution after a coal tar sealant application. This time it is in Andover, Massachussetts during the first week of October 2010. Many of these go unreported. Some industry applicators say this is just part of doing business! Perhaps the easiest way to prevent this is to not apply coal tar sealants at all.

Gulf Oil Spill Leaves Behind Cancer Causing Agents
Earlier this year our nation suffered the largest oil spill in our history. Every day we continued to hear the news that more oil was entering the
Gulf of Mexico. No doubt this has greatly effected the ecosystem and the local economy. Some scientists from the have completed a study that attempts to quantify the amount of oil that spilled and to further explain the chemical constituents in the oil. University of Oregon
Did you know that the quantity of "cancer causing" polycyclic aromatic hydrocarbons (PAHs) dumped in the Gulf from the oil spill only amount to half of what is sprayed throughout our country annually as coal tar sealants? That's right. Put another way is that we spread the equivalent quantity of PAHs of the Deep Water Horizon every six months of every year in around our homes, schools and businesses! Does that make sense?
