Biotic control of LNAPL longevity - laboratory and field- scale studies
MetadataShow full item record
Natural source zone depletion (NSZD) is an emerging strategy for managing light nonaqueous phase liquids (LNAPLs). Unfortunately, little is known about NSZD rates over extended periods of time, where heterogeneous redox conditions and changing LNAPL saturations may influence processes governing losses. Understanding long-term rates is central to anticipating LNAPL longevity under both natural and engineered conditions. Herein, laboratory and field-scale modeling studies were conducted to evaluate LNAPL longevity. Laboratory studies evaluated loss rates as a function of total contaminant concentration ...
