Researcher Mike Jansen explained the relationship of the underground TCE plume to the base, and the Irvine, California neighborhoods that now sit on top of it, using an official Navy publication that tells the story of the base and neighborhood contamination. "This is the area right here where the majority of the TCE was used, right in this area.Desorption is the most significant TCE input process evaluated. A mass-balance analysis shows that the removal of TCE from the plume by natural attenuation processes is of the same order of magnitude as the input of TCE to the plume. The natural-attenuation rate constant calculated from field TCE concentrations and time-of-travel data is in ...TCE is “known to be a human carcinogen,” according to the federal Department of Health and Human Services. The state has listed two dozen “contaminants of concern” for cleanup within the plume. Thirteen chemicals and metals are designated by federal agencies as carcinogens, likely carcinogens or suspected carcinogens. In addition, attaining higher resolution by increasing sample frequency increases costs substantially.
