Article 1: Chlorinated hydrocarbons rank among the most persistent and difficult groundwater contaminants to clean up, but remediation of chlorinated solvent sites to residential standards doesn't have to be impractical. A case study shows how coupling multiple remediation technologies with other factors — including innovative reagent delivery methods, dedicated performance monitoring and active discussions with regulators — can lead to such site closure within a reasonable time frame.

Article 2: Hydraulic fracturing and horizontal drilling can rejuvenate domestic oil fields by tapping into additional sources of natural gas, areas where heavier hydrocarbons such as ethane, propane, butane and gasoline also are available. Such natural gas liquids (NGLs) have higher market value when separated from the natural gas stream, and a case study shows how modular construction can help accelerate the schedule for building an NGL fractionation plant.

Achieving Residential Closure at a Chlorinated Solvent Site

Chlorinated hydrocarbons rank among the most persistent and difficult groundwater contaminants to clean up, but remediation of chlorinated solvent sites to residential standards doesn't have to be impractical. A case study shows how coupling multiple remediation technologies with other factors — including innovative reagent delivery methods, dedicated performance monitoring and active discussions with regulators — can lead to such site closure within a reasonable time frame.

NGL Fractionation Plant on the Fast Track

Hydraulic fracturing and horizontal drilling can rejuvenate domestic oil fields by tapping into additional sources of natural gas, areas where heavier hydrocarbons such as ethane, propane, butane and gasoline also are available. Such natural gas liquids (NGLs) have higher market value when separated from the natural gas stream, and a case study shows how modular construction can help accelerate the schedule for building an NGL fractionation plant.
