For stations beyond 100 m, predictions of detrimental effects, based on the
comparisons to the criteria of Long et al. 1995, do not appear to be matched by the
benthic data. Published letters (Chapman 1995a,b) indicate that there is no reason to
expect such a relationship. Comparisons to standard criteria based upon biological
testing, and field observations each have their own role in the analysis of ecological risk:
"...numerical environmental quality criteria are useful generically for screening purposes,
but not for definitive assessments of, in particular, areas of the environment that fall
between 'very clean' and 'very polluted'."
This work was supported by the United States Department of Energy, Office of Fossil
Energy, through the Metaire Site Office, with guidance from Dr. Brent Smith as project
officer. The primary contractor for the field study described in the text was Continental
Shelf Associates, Inc., Jupiter, Florida. Steimle and Associates, Inc., Metaire, Louisiana
supplied the data used the analysis. Work performed under Contract No. DE-AC02-
76CH00016 with the U.S. Department of Energy (A.F. Meinhold, P.I.).
