On December 14 & 15, 2011, Region 9 teamed up with ORD to present two
days of training on Phytotechnologies and Water Balance Covers, with each
taking a day. This two-day workshop, offered at the Region 9 offices in San
Francisco, was intended to teach regulators, owners and operators,
consultants, and engineers the basic principles for growing plant systems
for environmental remediation, enhancement, and waste containment. Topics
covered included alternative cover design, soil selection, construction, and
monitoring, along with discussions of regulatory issues. Regional case
studies were emphasized. The days' offerings were mutually exclusive, so the
attendees were not the same each day, as their interests and needs varied.
On day 1, a number of speakers provided background and practical
engineering application information on phytotechnologies, including an
overview, use for site remediation and wastewater management, current
research and a global perspective on the topic. We heard from ORD's Steve
Rock to kick things off. Then Amanda Ludlow, Wai Kwan, Scott Knoepke and
Walt Eifert, all from Roux Associates, along with Norman Terry from
University of California at Berkeley, provided presentations covering the
topics mentioned above.
Day 2 was dedicated to discussions on water balance covers or what are
sometimes called evapotranspiration caps. They can be considered a specific
application of phytotechnologies. Among the speakers for day 2 were Drs.
Craig Benson and Bill Albright. Dr. Benson is the Chair of Civil and
Environmental Engineering and Geological Engineering at the University of
Wisconsin-Madison. Dr. Albright is Research Hydrogeologist at the Desert
Research Institute of the Nevada System of Higher Education. ORD's Steve
Rock and Jim Kelsey from Daniel B. Stephens and Associates rounded out the
speakers for day 2.
Below are the agenda from the two days and the associated presentation
materials. Also posted is some modeling information from day 2. The
presentation files are named according to the speaker and can be matched to
the posted agenda for the two days. A list of attendees is here as well.
