Abstract: A system, method and apparatus for monitoring the subsurface at facilities for the presence of volatile organic compounds (VOCs). A surface penetration is made in a facility surface providing access to the subsurface soil beneath the facility. A soil probe is placed in communication with the soil beneath the facility surface and used to withdraw samples of soil gas from the pore space within the soil. The soil probe includes a monitoring port configured to seal the surface penetration and minimize the movement of undesirable materials between the facility and the subsurface via the monitoring port. The soil probe has an end filter in communication with the subsurface under the facility. The monitoring port is coupled to a sampling pump used to withdraw the soil gas sample. Soil gas samples are periodically obtained and analyzed for the presence of VOCs.

Abstract: The present invention provides a system by which customized quality computer-based training (“CBT”) can be presented over a global network such as the Internet with low development costs, low hosting costs, inexpensive class production, and high-quality audio-visual content. A student, having an active connection to the server from a remote client, enters the CBT website and registers as a new student by providing necessary pertinent information to the server host. Upon completion of the registration process, the student begins his or her interaction with the online computer-based training plan. The online plan includes digital images and digital audio that is compressed and transmitted from a host server to the student's computer via the Internet. Better compression provides for a more fluid viewing of the plan without sacrificing image or audio quality.

Abstract: An improved process for neutralization of acid tars employs a bulk neutralizing agent having a specific gravity greater than that of the acid tar to be neutralized. The bulk neutralizing agent, generally in excess of an amount sufficient to accomplish neutralizing, is spread on top of the acid tar. The neutralizing agent will then begin to sink into the tar. The sinking occurs at a slow rate which is a function of tar viscosity, tar specific gravity, neutralizing agent specific gravity, and temperature. As the neutralizing material sinks into the acidic tar it reacts with the acid neutralizing the tar in situ and depleting the neutralizing agent. Not only does the reaction increase the pH of the tar, it also produces a reaction product with improved physical properties which promotes ease in handling.

Abstract: The present invention relates generally to a method and device to treat and remediate contaminated soils and sludges and, in particular, relates to a treatment unit which is transportable, quickly mobilized, and capable of remediating large quantities of waste by exothermic stabilization processes such as the calcium oxide based DCR process.
