Abstract
Methods and systems for evaluating a distribution and recoverability of a light non-aqueous phase liquid (LNAPL) or a dense non-aqueous phase liquid (DNAPL) in fractured substrate are provided. Also provided are methods and systems for evaluating a distribution and recoverability of a light non-aqueous phase liquid (LNAPL) or a dense non-aqueous phase liquid (DNAPL) in other substrates, including a layered porous media substrate. Also provided are methods and systems for calibrations related to DNAPL transmissivity.

A method of evaluating a distribution and recovery of a non-aqueous phase liquid (NAPL) in a subsurface comprising:
- identifying a plurality of mobile non-aqueous phase liquid intervals (MNI) in the subsurface;
- and
- determining a transmissivity of a non-aqueous phase liquid (NAPL) in the subsurface.
A system for evaluating a distribution and recovery of a non-aqueous phase liquid (NAPL) in a subsurface comprising:
- a first component for determining a transmissivity of a non-aqueous phase liquid (NAPL) in the subsurface;
- and
- a second component for identifying a plurality of mobile non-aqueous phase liquid (NAPL) intervals (MNI) in the subsurface.
A method of evaluating a distribution and a recoverability of a dense non-aqueous phase liquid (DNAPL) comprising:
- testing a transmissivity of the dense non-aqueous phase liquid (DNAPL), wherein the testing the transmissivity of the dense non-aqueous phase liquid (DNAPL) comprises:
- placing a first transducer in the dense non-aqueous phase liquid (DNAPL);
- recording a first pressure measurement from the first transducer;
- calculating an elevation of the dense non-aqueous phase liquid;
- placing a second transducer in a water column near the dense non-aqueous phase liquid (DNAPL);
- recording a second pressure measurement from the second transducer;
- calculating an elevation of the water column;
- and
- comparing the elevation of the dense non-aqueous phase liquid (DNAPL) to the elevation of the water column to determine a thickness of dense non-aqueous phase liquid (DNAPL);
- determining a high resolution mobile interval definition of the dense non-aqueous phase liquid (DNAPL);
- and
- integrating the definition into a conceptual site model.
