He provides alternative dispute resolution (ADR) services for complex problems relating to pollution liability and damages allocation for environmental cleanup and restoration actions throughout the United States.

These assignments have involved PRP investigation, site history reconstruction, transactional database development, position paper and expert report evaluation, cause/effect analysis, environmental forensics, and damages and financial analysis. Several of his allocation assignments have been performed as a neutral party authorized and funded by the U.S. Environmental Protection Agency.  He also works as a court-appointed neutral for ADR procedures involving cost allocation problems.  Mr. Hengemihle has served as an expert witness in several Superfund contribution actions.
