Chlorinated solvents have properties that make them useful in applications of degreasing fats, oils, waxes, and resins. They have also been demonstrated to be harmful to human and ecological health. Spills and leaks of chlorinated solvents often result in the form of non-aqueous phase liquids (NAPL) in the subsurface, as dissolved contaminants in groundwater, as aquifer sediments, and as vapors in unsaturated zones.
Vadose Remediation offers remediation solutions for chlorinated solvents in the form of thermal remediation and zero valent iron injection solutions. More information on each of these solutions can be found below. Contact Vadose Remediation for more information on chlorinated solvents remediation options or to schedule a customized presentation for your team.
Thermal remediation can remove chlorinated solvents such as TCE and PCE at relatively low temperatures using either electrical resistance heating (ERH), thermal conduction heating (TCH), or steam enhanced extraction (SEE). In-situ thermal treatment increases the mobility of chlorinated solvents with increased temperature, allowing for the removal or destruction of these contaminants.
SourceKill is an emulsified zero valent iron which is injected into the DNAPL-contaminated zones. The DNAPL is then sequestered into the emulsion for reaction with ZVI. Through a process known as chemical reduction, the DNAPL and its daughter products are degraded into ethene, ethane and other hydrocarbons. The by-products are finally broken down through biological activities in the subsurface.
CleanER iZVI is a precisely blended liquid-suspension concentrate that is injected, via DPT or injection wells, to address chlorinated volatile organic compounds (CVOCs). The unique formulation promotes broad dispersion in the subsurface at low injection pressures, which optimizes distribution and contact. Through reductive dechlorination contaminants are broken down into ethene.
