Emerging Core Concepts for Assessment and Enhancement of Abiotic Natural Attenuation of Groundwater Contaminants

Abstract

It is now widely recognized that abiotic processes play an important role in the natural attenuation (NA) of groundwater contaminants, and this development has created demand for new and improved methods of measurement and/or enhancement of abiotic NA processes. The overall aim of this project was to develop several of these methods into core concepts that will help to form a foundation for field applications of abiotic NA, and related varieties of in situ chemical reduction (ISCR). The three methods developed under ER-2620 include (i) standardized and validated performance metrics, (ii) enhancement of performance by mediation or activation, and (iii) rigorous yet practical quantification of reductant demand. Each of these objectives was pursued through a combination conceptual model development, data mining, laboratory experiments, and modeling.
