| Description |
Methods developed by the Toxics Program to assess the movement
of contaminants in bottom sediments into the water of San
Francisco Bay, California, have been applied at Lake Coeur d'Alene,
Idaho (Scientists call the movement of dissolved contaminants, which can be either into or out of bottom sediments the benthic flux). Remediation strategies for the Bunker Hill Superfund Site,
Idaho, currently focus on channel modifications along the Coeur
d'Alene River that flows into Lake Coeur d'Alene. Results of a USGS
study to assess contaminant sources in the lake indicated that for
virtually all contaminants of concern, the abundance of contaminants
that have accumulated ubiquitously in the lake-bottom sediment over
the past century would limit the effectiveness of the remediation.
A decrerase in the contaminant load from the Coeur d'Alene River could result in an increase in the amount of contaminants released by the lake's bottom sediments (an increase in the benthic flux of contaminants into the water column). Computer modeling results show that
a potential increase in contaminants released from the bottom sediments
would be caused by an increase in the concentration gradient across
the sediment water interface caused by the river cleanup. Resource
managers can use this methodology to assess the effectiveness of
remediation strategies for other contaminated water bodies.
