Abstract:

The purpose of this document is to provide users with information on 1 fate, transport and transformation of perchlorate in different geochemical environments 2 emerging andor specialized technologies for evaluating perchlorate attenuation in groundwater and 3 a tiered approach for evaluating the MNA of perchlorate. This protocol does not provide a step-by-step guide to MNA of perchlorate. Instead, it presents several procedures to aid the user in determining if natural attenuation processes are sufficient to meet remedial objectives in a reasonable time frame while protecting human health and the environment. Before implementing a study to assess MNA of perchlorate, users should be generally familiar with previously developed protocols for assessing the MNA of petroleum hydrocarbons and chlorinated solvents. Depending on site-specific conditions and regulatory factors, the user can implement some or all of these procedures to develop a weight-of-evidence case for MNA as a viable remedial strategy for perchlorate-impacted groundwater.
