Soil Gas Investigations at MGP (Manufactured Gas Plant) Sites: An Evaluation of Alternative Compounds. Topical Report January 1989-June 1989

摘要

Soil gas surveys are frequently used to detect hotspots of contamination during the initial phases of investigation at manufactured gas plant (MGP) sites. Most soil gas surveys at MGP sites have used benzene, toluene and xylene (BTX) as target analytes. The technique, however, has failed to detect coal tar contamination in some instances. Consequently, the objective of the research was to evaluate the use of alternative target analytes, including carbon disulfide, thiophene, pyridine, ethylbenzene, styrene and 1,2,4-trimethybenzene for the detection of tars at MGP sites. Of these only ethylbenzene and 1,2,4-trimethylbenzene were consistently detected in tars.
