"Experts on contaminated sites said that a Superfund listing typically stirs contradictory emotions. On one hand, some people who live nearby may feel demoralized and even frightened by the finding of serious contamination and worry about its impact on real estate values; on the other, some are often relieved to get a firm commitment to clean up the toxic substances in their midst.
