This technical report documents VS2DT, a computer program that models how chemical solutes move through variably saturated porous soil and rock, accounting for processes such as advection, hydrodynamic dispersion, decay, adsorption, and ion exchange. The document includes the underlying mathematical theory, numerical methods, data input instructions, and verification problems comparing the program's results against known analytical solutions. While primarily a groundwater contaminant transport modeling tool, it has no direct connection to airport noise policy.

This document presents chemical composition data for various petroleum fuel types, including fresh gasoline, weathered gasoline, fresh diesel, weathered diesel, and heavy fuel oil. It breaks down the percentage and concentration (mg/kg) of aliphatic and aromatic hydrocarbon fractions across different carbon chain length ranges. The data appears to support environmental modeling and site assessment work, likely related to fuel spill or contamination analysis.
