The Natural Attenuation training courses provide a framework for thinking about natural attenuation based on science, focusing on the basic information needed to determine and document the conditions necessary for natural processes to be an effective part of remediating contaminants in groundwater.
The Attenuation Processes for Metals and Radionuclides training course facilitates implementation of the new EPA guidance for monitored natural attenuation (MNA) of metals and radionuclides with a framework providing a consistent basis for states, stakeholders, federal agencies, and site owners to evaluate and implement attenuation-based remedies.
The Bioremediation of DNAPLs (BioDNAPLs) training course addresses the selection and design of in situ bioremediation (ISB) systems for chlorinated ethene DNAPL source zones, as well as technical and related regulatory considerations.
The Enhanced Attenuation: Chlorinated Organics (EA) training course provides direction to regulators and practitioners on integrating EA into remedial decision making for a smooth transition between aggressive remediation and monitored natural attenuation.
The In Situ Bioremediation (ISB) training courses address the systematic characterization, evaluation, and appropriate design and testing of ISB for biotreatable contaminants.
