This report presents a tool to assess, classify, predict, and quickly communicate fate and transport characteristics of chemical mixtures released into the soil and groundwater as a result of hazardous materials transportation incidents. The tool was developed with a wide range of users in mind. For technical users, the property output table generates the fate and transport properties of an input mixture. For emergency response teams, it provides a quick review of the emergency response requirements of a spill. For non-technical users, a color-coding function is included in the tool to compare the critical fate and transport properties to their pure chemical counterpart and highlight the key parameters affecting the mixture transport in the saturated and unsaturated zones. The tool can also be used to determine whether shipping certain chemicals separately or in mixtures will have significantly higher costs if an incident occurs and to estimate relative costs and timeframes of cleanup after an incident occurs. The chemical mixture tool, a user guide, and the contractor's final report for HMCRP Project 06 can be found on CRP-CD-90, which is attached to this publication. This publication contains a summary of the final report, the Contents of the final report, Appendix H - the research teams's Tool Design Process Example, and Appendix M - the User Operational Manua (Author/publisher) This report on available online at http://onlinepubs.trb.org/onlinepubs/hmcrp/hmcrp_rpt_002.pdf
