This page provides a description and a link to a "Mass Distribution in Multiphase Systems" modeling tool that can be used for modeling exposure levels or information needed in exposure assessment.

Short description

The distribution of mass in a multiphase system depends on partitioning between the phases. The partition coefficients depend on properties of the chemical and the amounts of water, NAPL, air and organic carbon in the pore space. This EPA's on-line calculatior calculates the partitioning between between water, air, fuel and solids in the subsurface.
