NGWA Webinar to Focus on Use of Nitrogen-15 and Carbon-13 Tracers
Webinar will be open to all levels of groundwater professionals
A webinar on the use of nitrogen-15 and carbon-13 to trace NO3- and NH4+ contamination and attenuation in groundwater will be hosted by the National Ground Water Assn. (NGWA) on Sept. 27 at 11 a.m.
It will address:
Recharge and pathways of groundwater and nutrients in agricultural watersheds;
Redox geochemistry and the nitrogen cycle;
Nitrogen-15 in NO3- and NH4+ from agricultural, domestic and industrial sources; and
Sampling and analysis of nitrogen species for isotope analysis.
The webinar will be presented at a level appropriate for all groundwater professionals, including environmental consultants, consulting engineers and geologists, and water supply engineers. University-level chemistry and/or geochemistry are desirable.
The presenter is Ian Clark, Ph.D., professor of isotope hydrology at the University of Ottawa, Canada.
