Welcome to the HowToMNA website

This site provides a series of four Modules containing presentations linked to a more detailed background document along with self-test questions and answers. The overall aims of the course are:

provide an introduction and background to monitored natural attenuation (Module One)
provide timely and accurate information about the technical aspects of monitored natural attenuation in groundwater (Module Two)
provide timely and accurate information about the technical aspects of monitored natural attenuation of hydrocarbons in groundwater (Module Three)
provide timely and accurate information about the technical aspects of monitored natural attenuation of chlorinated solvents in groundwater (Module Four)
teach the use of screening tools for the evaluation of natural attenuation of potential sites
