A Greener Indiana

Everybody can do something to make a greener Indiana


Wayne ASS-phalting back again early morn. can't they get it done the first
time, nasty, nasty petro, tar stink in road next to my veggie, herb patch.....

Did you know asphalt is one of the most commonly 'spilled' petroleum products in the US??

Asphalt used on roads and in water pipes is supposedly used in a manner which binds most of the harmful
compounds together as part of a tough, cement-like solid. In layman's terms, the good news is that the many harmful compounds typically found in asphalt are presumably bound in place fairly tightly in many roadway and other controlled uses. The bad news is that some of these harmful compounds may not always be as firmly and as universally "locked in place" as some have assumed

Hazards include inhalation of compounds in heated or fresh asphalt as well as ingestion of PAHs entering the food chain as the result of breakdown of asphalt. Finished waters from various treatment sites are transported to consumers through a variety of pipelines.

Parking lots and other paved areas are sealed to protect them from the
elements. Two main sealants are used in the US: asphalt (crude oil
base) and coal-tar base.

Coal-tar is formed when coal is coked, a process to prepare coal for use as a fuel. Coal-tar base sealants contain high levels of a class of chemicals known as polycyclic aromatic ... See More hydrocarbons (PAHs). A mix of different types of PAHs are found in the sealant.

The long-lived PAHs widely pollute the environment, wildlife and people.
These highly dangerous chemicals are expected to cause cancer in people.

Thanks Ellen for yet another AWESOME post! I learned far more than I ever wanted to know about ass-phault while working with the solid waste director @ HEC in early 1990's. My 'education' of it continued over the years....many peeps also don't know that coal/energy companies think it's a real nifty & cheap way to use(dispose) of dirty,toxic coal ash..
ewwww..it is truly stinky, toxic stuff!!!! and it's EVERYWHERE,argh!!!

I had never really thought about asphault? One more thing that ends up all over the place.
