First Contest Winner… Next Quiz Question!

We have a winner!  Sue Arnold of CMT Engineering Laboratories – a construction material testing and inspection laboratory – was selected at random from the seven correct responders to last week’s coal ash question.

But before we get to her correct response, here is the contest question for this week:

What historic site in North Dakota hosts the nation’s most comprehensive demonstration of the variety of ways coal ash can be recycled in building materials?

If you think you know the answer, e-mail it along with your name and contact information to info@recyclingfirst.org.

Last week’s question was: What landmark building in our nation’s capital was constructed using concrete containing coal ash and now houses offices of the people who will decide whether coal ash is hazardous?

The correct answer:  The Ariel Rios Federal Build­ing, headquarters for the U.S. Environmental Protection Agency, contains concrete made using coal fly ash! A photo of the building is below.

Congratulations, Sue!
