Test site description

In addition to releases from the various components or activities that make up the production and distribution system for petroleum products (the oil system), many older waste sites show TPH-related site contamination. Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) site descriptions often mention petroleum, oil and grease, or petroleum, oil, and lubricants (POL) as present at a former waste disposal site. An example is given below for a waste oil recycling site, where TPH-type chemicals were obviously a common site contaminant. The CERCLA clean-up actions, however, focus on a range of specific hazardous or toxic chemicals. Some of the specific chemicals (e.g., toluene) would show up in a TPH test, but the chlorinated solvents and metals do not. Since a site cannot be prioritized for CERCLA attention if the only problem involves TPH site... 

As shown in Table 2, the properties of the Lamprophyre properties and the surrounding rock are the same except for permeability and thermal conductivity. The mechanical rock-mass properties are obtained from the geological description of the Grimsel Test Site (Kneussen et al., 1989). Significantly, the Young s modulus of the rock mass was reduced to 70% of its value for intact rock.

The approach to the Rock Mechanics Site Descriptive Model was tested by predicting the rock mechanics properties of a 600 m x 180 m x 120 m rock volume at the Aspb Hard Rock Laboratory (HRL) in Sweden using limited borehole data of the type typically obtained during a site investigation (Hudson, 2002). These predicted properties were then compared with best estimate properties obtained from a study of the test rock volume using additional tunnel and tunnel borehole data. This exercise was known as the Test Case, and directly indicates how some of the input required for modelling can be specified and tested. 

The Test Case exercise was invaluable in forcing the generic approach to the Rock Mechanics Site Descriptive Strategy to become a specific approach for the Aspd HRL rock volume being considered. The predictions of the rock mass modulus between fracture zones made by the empirical and theoretical teams were similar and close to the best estimate values. The predictions of the rock mass modulus in fracture zones were more varied, because few data were available and hence there was greater choice in the assumptions necessary to make the predictions. The empirical and theoretical teams predictions of the rock strength were also more varied, mainly because few data were available and different interpretations of rock mass strength were used.

Description of Experiments The Desert Tortoise Series of ammonia spill experiments was performed by LLNL at the Frenchman Flat area of the Nevada Test Site during the summer of 1983. There were four experiments for the study of the size, shape, and temperature of the ammonia clouds, as well as the extent of the hazardous concentrations downwind. In order to simulate simple cases, which later could be modeled, the tests were performed at constant pressure and on the dry lakebed, which provided a relatively flat and smooth surface.
