ABSTRACT:
According to the methods, a site is investigated for possible selective removal of sediment containing a contaminant. An adjusted contaminant concentration is calculated for sediment zones on the site. The site preferably contains a water course. A determination may be made as to whether the sediment zone needs remediation by comparing the adjusted contaminant concentration to a standard. The method may be at least partially implemented in a computer.
