Treatment Technologies

Combined Remedies

Halogenated Alkanes

"Treatment train" approaches represent a practical means to address difficult remediation problems, such as pure or dissolved-phase DNAPL contamination in soil and groundwater. The optimal remedial action at a given site often requires the use of multiple technologies that can be used either sequentially or concurrently. A single remedial technology is rarely the most cost-effective approach throughout the life cycle of a cleanup project.

Please see the pages on individual technologies used to treat halogenated alkanes for descriptions of these technologies.
