Unfortunately, each group has had to come to grips with, and often fight, agency plans to implement natural attenuation. If it includes significant amounts of dispersion and dilution, it is a do-nothing approach to cleanup. On the other hand, there are plumes that undergo significant chemical and biological destruction. It seems to me that it is important for all stakeholders to understand the policy and technical implications of natural attenuation. This does not mean that one is selling it - rather trying to understand the circumstances when one should strongly oppose it and others where it may be acceptable with safeguards built into the remedy (e.g., strongly worded contingency plans, monitoring etc.).
