SUMMARY:W3 Seminar: Numerical estimation of nitrogen loading from septic sy
 stems to surface waterbodies
DESCRIPTION:Numerical estimation of nitrogen loading from septic systems to
  surface waterbodies\nMing Ye\, Professor\, Department of Earth\, Ocean an
 d Atmospheric Science\, Florida State University\nAbstract: Nitrogen pollu
 tion is one of the most prevalent and challenging environmental problems w
 orldwide. Treatment of domestic wastewater using onsite sewage treatment a
 nd disposal systems (a.k.a. septic systems) is considered as the second la
 rgest nitrogen source in Florida. For managing nitrogen pollution due to s
 eptic systems\, we developed software\, called ArcGIS-based Nitrogen Load 
 Estimation Toolkit (ArcNLET) for simulating nitrogen transport in soil and
  groundwater and for estimate nitrogen loading from septic systems to surf
 ace waterbodies. ArcNLET first simulates one-dimensional unsaturated flow 
 and reactive transport of ammonium and nitrate in soil between drainfields
  and water table\, and then simulates two-dimensional groundwater flow and
  reactive transport of ammonium and nitrate in groundwater. ArcNLET is an 
 easy-to-use computer tool\, and can be used to estimate long-term nitrogen
  loading from septic systems to surface water bodies to support management
  of nitrogen pollution. This seminar will first present the groundwater fl
 ow and solute transport models behind ArcNLET\, and then introduce several
  applications of ArcNLET at several study site across the state\, includin
 g a recent application for estimating the relations between nitrogen atten
 uation rates and distances from septic systems to water table and surface 
 waterbodies. We recently developed the Python version of ArcNLET for ArcGI
 S Pro\, and the source codes and user manual are available at GitHub (http
 s://github.com/ArcNLET-Py/ArcNLET-Py) for free download.
