NJDEP Guidance
The NJDEP requires that a site-specific impact to ground water (IGW)
soil remediation standard be developed for contaminated soil. The guidance describes four methods that can be used.
- Soil-Water Partition Equation
- Synthetic Precipitation Leaching Procedure
- SESOIL Modeling
- SESOIL/AT123D Modeling
There is one caveat, that sufficient site-specific data has been obtained on which to base the standard.
But that can be the problem.
The cost of characterizing the site could outweigh the benefit of reduced remedial action based on the higher IGW standard.
Preliminary modeling can be used to determine if the investigation costs are warranted.
SESOIL and the Nile River
It might seem odd to find a reference to the Bahr el Ghazal swamp, a tributary to the Nile River, in the original SESOIL user’s guide, but there it is.
In 1980, Siu-On Chan and Peter Eagleson at the Massachusetts Institute of Technology were given the task of determining where the water entering the swamp went.
It had been assumed that most of the water evaporated, but no one was sure.
They were to asked to find out how much water could be recovered if a canal was constructed to bypass the swamp.
Reclaimed water would be sent downstream where it would be used by Sudan and Egypt for agricultural production.
SEVIEW Tranining December 6, 2017 at the Rutgers Continuing Studies Conference Center
EARLY BIRD SPECIAL - Save 50% on training
Pending approval for 4 CECs in New Jersey. Approved for 4 technical CECs in Massachusetts and Connecticut.
Training will cover the use of the SESOIL and AT123D models in the SEVIEW software. SEVIEW 7.1 is the only software that meets the specifications of the NJDEP guidance documents on:
- Using the SESOIL Transport Model to Assess the Impact to Ground Water Pathway
- Using the Combined SESOIL/AT123D Models to Develop Site-Specific Impact to Ground Water Soil Remediation Standards For Mobile Contaminants
Instructor:
Robert Schneiker, PG, MS, President, ESCI, LLC
With 25 years of modeling experience Mr. Schneiker is the sole designer and developer of the SEVIEW modeling software. He has conducted numerous SESOIL and AT123D training seminars and has presented papers on modeling in the United States, the European Union, and Canada.
