Vapor intrusion evaluation for redevelopment of former industrial facilities

Evaluation of Vapor Deposition Techniques for Membrane Pore Size Modification

The suitability of three vapor deposition techniques for pore size modification was evaluated using polycarbonate track etched membranes as model supports. A feature scale model was employed to predict the pore geometry after modification and the resulting pure water flux. Physical vapor deposition (PVD) and pulsed plasma-enhanced chemical vapor deposition (PECVD), naturally, form asymmetric na...

Grand Prairie Vapor Intrusion Investigation

Environmental liability and redevelopment of old industrial land.

Many communities are concerned about the reuse of potentially contaminated land (brownfields) and believe that environmental liability is a hindrance to redevelopment. However, with land price adjustments, liability might not impede the reuse of this land. This article studies state liability rules-specifically, strict liability and joint and several liability-that affect the level and distribu...

Fuzzy Real Options in Brownfield Redevelopment Evaluation

Real options modeling, which extends the ability of option pricing models to evaluate real assets, can be used to evaluate risky projects because of its capacity to handle uncertainties. This research utilizes possibility theory to represent private risks of a project, which are not reflected in the market and hence are not fully evaluated by standard option pricing models. Using a transformati...
