Shallow land burial trenches are typically long, narrow, excavations with an engineered floor, an engineered drainage collection and monitoring system, and an engineered cover system.  1, fiche 1, Anglais, - shallow%20land%20burial%20trench

As used in this context, the word "engineered" refers to the fact that features and materials have been designed or selected to accomplish certain functions. In shallow land burial the materials are usually natural rather than man-made.  1, fiche 1, Anglais, - shallow%20land%20burial%20trench

Typically, each [shallow land burial] trench has a sloping floor cut into the natural soil and a French drain of gravel down one of the long sides. The trench bottom is covered with a foot or two of sand to allow water to flow freely into the French drain, especially when the trench is open during operations. Sampling pipes or tubes are placed against the trench wall, with their lower ends in the French drain, when the trench is dug. Monitoring of each disposal unit(engineered trench) is accomplished by sampling any water found in the French drain through these tubes and analyzing its contents. Sampling wells are placed around the perimeter of the facility, and elsewhere if desired, and air sampling is conducted at least until the end of the operations.  1, fiche 1, Anglais, - shallow%20land%20burial%20trench

The SPIR system can also be applied to long perimeter applications by chaining them together for continuous coverage. However, this is not cost effective except for short segments, and has a number of other disadvantages when compared with the long-time sensor.  1, fiche 5, Anglais, - long%2Dline%20sensor

The needs of long perimeter sites can be met by lining them together in a daisy-chain fashion. This is the traditional block sensor approach and, since the units are relatively low cost, would appear to be a viable solution.  1, fiche 6, Anglais, - block%20sensor
