An Examination of the Denver Drug Court: The Impact of a Treatment‐Oriented Drug‐Offender System

This paper reports on a retrospective study of the Denver Drug Court that was conducted to assess the court's impact on court processing, treatment matching, and offender recidivism. A sample of 300 offenders from the Denver Drug Court and drug offenders from two previous years prior to the drug court was obtained. Quasi‐experimental procedures were used to examine differences in measured variables across each offender cohort. Data for this study were collected from court records as well as through on‐line arrest records. This paper begins with an exploration of the organizational framework of the Denver Drug Court and the court's related treatment options. It also examines the extant literature on the effectiveness of drug courts. Analysis of the data indicates that the Denver Drug Court has reduced case processing time and it has slightly reduced the amount of time offenders spend in presentence confinement. Unlike previous studies of drug courts, this study attempted to examine the court's ability to match offenders to treatment needs. Analysis of the available data, although limited, suggests that offenders are being matched to appropriate levels of treatment. Finally, data analysis indicates no significant differences in revocation or rearrest rates. This article concludes with a discussion of the controversial nature of drug courts. Directions for future research are offered.     

Vapor Intrusion into Large Commercial/Industrial Facilities

Inhalation exposure from vapor intrusion has become a priority over the past several years for federal, state, tribal, and local environmental agencies. This article discusses the identification of vapor intrusion conditions and mitigation approaches for large commercial and industrial facilities. Factors to be considered in the design and implementation of remedial measures to address source areas below a building include identification of source areas, access to the sources, feasibility of active remedial technologies to address the source area, and whether a remedial technology will be effective in reducing or eliminating the potential for vapor intrusion into the overlying building. In the event a mitigation system is deemed appropriate, the key factors to be considered in the design and construction of such systems include size and construction details for the building; uses and occupancy type; and type of heating, ventilation, and air conditioning (HVAC) systems in the building and associated air exchange rates and operation and maintenance considerations. This topic will remain a priority for regulatory agencies and a key concern of building owners.
