Evaluating the Progress of Natural Attenuation in Groundwater

Evaluating the Progress of Natural Attenuation in Groundwater

This course presents a simple, statistically based approach for evaluating the progress of natural attenuation from the data collected during site characterization and long term monitoring. The course also provides an approach to establish the time that should be required to attain the cleanup goals, and an approach to evaluate attenuation within a review cycle to determine whether attenuation within that period of time is adequate to allow the site to attain the ultimate cleanup goal. Monitored Natural Attenuation (MNA) is widely applied to groundwater contamination at hazardous waste sites. Under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), MNA is considered to be a remedy like any other remedy. When MNA has been selected as a remedy, concentrations of contaminants in the groundwater are expected to achieve a cleanup goal at the site within a reasonable time frame. At many CERCLA sites, the time by which the goals are to be obtained is specified in the Record of Decision (ROD).

Once you complete your course review, you need to take a multiple-choice quiz consisting of twenty (20) questions to earn 4 PDH credits.

Learning Objectives

This course is intended to provide you with the following specific knowledge and skills:

  • The processes responsible for natural attenuation with a focus on biological degradation
  • An understanding of Monitored Natural Attenuation as a remedial technology
  • Monitoring and sampling required to evaluate MNA
  • Methods to estimate the time required for MNA to achieve cleanup goals at a hazardous waste site
