Description:
This paper focuses on managing costs (risk) related to sampling soil to characterize contamination and select a remedial alternative. To effectively manage cost, you need to determine the amount of data and quality of data necessary to make identified decisions. Because of the concern of making an incorrect decision (e.g., wondering what your supervisor would think if you made an error), you may tend to collect more data than necessary to make confident decisions. Collecting data with the goal of removing all uncertainty in the decision making process is not resources-effective, and probably cannot be achieved in reality. When decisions and decision criteria are clearly defined, it becomes apparent that additional data will not decrease uncertainty involved in making the decision. Unfortunately, many agency and industry project managers do not understand that uncertainty cannot be eliminated and that confident decisions can be made using data with identified levels of uncertainty. Many investigations are not focused on the ultimate objective, which under CERCLA, RCRA, and state regulations is to select a remedial alternative. The risk management decisions required under these regulations depend on collecting data or other information.
