Abstract:

Tar byproducts from former manufactured gas plants (MGPs), coking plants, and refineries share many chemical features.  However, the subtle differences between tars generated from coal and petroleum are often significant when the origin or date of release is a concern.  Often more important is the ability to differentiate low level MGP waste from urban background in sediments.  The origin of BTEX in groundwater, soil gas, and indoor air pose complications from partitioning and environmental weathering.    Environmental forensic techniques are constantly improving to address the evolving needs of MGP site investigations.  This presentation will focus chemical signatures produced by various tar generating and handling facilities for the purpose of estimating the tar origin and period of release.  Examples of different tar types and environmental testing methods will be discussed.
