I got this from the organization formerly known as Eastern Coal Regional Roundtable. The convention center in Cincinnati is called the "Duke Energy Convention Center"
National Monitoring Conference
The 9th National Monitoring Conference – Working Together for Clean
Water will be held the week of April 28 – May 2, 2014 in
Cincinnati, Ohio at the Duke Energy Convention
Center.
This biennial conference is the place to be to mingle with your
fellow water-quality monitoring professionals! The conference is a
showcase for new findings on the quality of the Nation's waters.
You'll also learn about the newest innovations and cutting-edge tools
in water-quality monitoring, assessment, and reporting; and have a
great time doing it.
The conference will host numerous influential speakers, hundreds of
presentations and exhibits, and dozens of workshops and field trips
to choose from. For more information, go to
