| Institution: | Suzanne Lesage is currently senior ground water chemist with the National Water Research Institute of Environment Canada, located in Burlington, Ontario (Groundwater Contamination, Rivers Research Branch, National Water Research Institute, Environment Canada, Burlington, Ontario, Canada L7R 4A6). Since 1986, she has specialized in the analysis of organic contaminants in ground water and studies their interaction and fate in the environment. She received a B.Sc. in biochemistry from the University of Ottawa, Ottawa, Ontario, in 1973, and a Ph.D, in chemistry from McGill University in Montreal, Quebec, in 1977. Prior to this appointment, she was head of the Organic Chemistry Laboratory of the Wastewater Technology Centre of Environment Canada in Burlington.;Patricia A. Lapcevic is a hydrogeologist with the National Water Research Institute of Environment Canada, located in Burlington, Ontario (Groundwater Contamination, Rivers Research Branch, National Water Research Institute, Environment Canada, Burlington, Ontario, Canada L7R 4A6). She received her B.Sc. in earth sciences from the University of Waterloo in 1985. She is currently involved in field studies of ground water flow through fractured sedimentary rock. |

| Abstract: | Multivariate plots were utilized to create fingerprints of aromatic hydrocarbon residues in ground water. The technique allows hydrogeologists to distinguish between residues of benzene, toluene, ethyl benzene, and total xylenes originating from ground water contact with petroleum in natural deposits and refined petroleum waste products. Examples were taken from deep-well injection of refinery wastes, natural petroleum deposits, municipal and industrial landfill leachates, coal tar and creosote contaminated waters, and varnish industry contaminated ground water. The data were plotted from ASCII files generated through either Lotus 123? or a database (The Manager?) report program, using a simple Fortran interactive program with Plot88? subroutines. |
