3.5` LANPAC® proven superior for removing PCE from groundwater in packed tower air strippers

The problem Dry cleaning fluids have contaminated groundwater supplies in all areas of the United States. One of the most common contaminants is PCE (perchloroethylene or tetrachloroethylene, Cl2C=CCl2). As a suspected carcinogen, PCE must be removed from water to very low levels. The US EPA maximum contaminant level (MCL) for PCE in drinking water is 5 ppb (5 parts per billion, ...

Santa Cruz Meets THM/DBP Challenge with Unique Air Stripping Process - Case Study

Summary Santa Cruz has successfully demonstrated an innovative way for the City to meet its water quality goals while using process recycled water as part of its supply source. Using the recycled water had caused concern about reliably meeting the U.S. EPA THM/DBP potable water quality standards in its finished water. The City evaluated various aeration treatment processes and chose an E-Z ...

Common Treatment Technologies for Nonhalogenated VOCs in Ground Water, Surface Water and Leachate

It may be necessary to know other subsurface information to provide remediation of VOCs in the ground water. Treatability studies to characterize the biodegradability may be needed for any biodegradation technology. Treatability studies are usually necessary to ensure that the contaminated ground water can be treated effectively at the design flow. A subsurface geologic characterization would be ...

Common Treatment Technologies for Fuels in Ground Water, Surface Water, and Leachate

It may be necessary to know other subsurface information to remediate fuels in ground water. Treatability testing to characterize contaminant biodegradability and nutrient content may be needed for any biodegradation technology. A subsurface geologic characterization would be particularly important to characterize the migration of NAPLs. Recovery tests are usually necessary to design a ...

Common Treatment Technologies for Nonhalogenated VOCs

Soil vapor extraction (SVE), thermal desorption, and incineration are the presumptive remedies for Superfund sites with nonhalogenated VOC-contaminated soil. Because a presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site, the presumptive remedy approach will accelerate site-specific ...
