Public Activities

Expert has been a consultant with a Civic League and a Civic Alliance in Delaware regarding the residential development of a badly contaminated golf course.  He has provided interpretive information regarding feasibility assessments for development plans and has helped the communities make more informed decisions in how their concerns should be directed.

Expert does assess modes of exposure from a toxicological point of view.  He also has done some public speaking on the subject in formats such as direct lectures as well as panel discussions.  He has consulted closely with state senators regarding the public health hazards of golf courses and has helped initiate major reactions to deficiencies in remediation plans by making public statements.
