Trickling filter. [It consists] of an artificial bed of coarse material, such as broken stone ... slate, slats, brush, or plastic materials, over which wastewater is distributed or applied in drops, films, or spray from troughs, drippers, moving distributors, or fixed nozzles, and through which it trickles to the underdrains, giving opportunity for the formation of zoogleal slimes which clarify and oxidize the wastewater.  6, fiche 1, Anglais, - trickling%20filter

Un lit bactérien est constitué par un empilage de 1 à 3 mètres de roches ou autres matériaux sur lesquels se fixe la masse mucilagineuse - ou zooglée - dans laquelle vivent les micro-organismes [...] Durant la traversée de ce lit, les matières polluantes sont retenues par les boues gélatineuses. Le drainage à la partie inférieure est prévu pour collecter l'eau tout en permettant une circulation naturelle d'air.  9, fiche 1, Français, - lit%20bact%C3%A9rien

Monitoring wells should effectively achieve one or more of the following objectives: Provide access to the groundwater system for collection of water samples ... Measure the hydraulic head at a specific location in the groundwater flow system ... Provide access for conducting tests or collecting information necessary to characterize the aquifer materials or their hydrologic properties.  3, fiche 2, Anglais, - monitoring%20well

Figure 6. 1 illustrates a typical open disposal trench at the Barnwell facility. The trench floor is sloped slightly and covered with a layer of sand to facilitate collection of percolating water in a French drain. A number of pipes allow any water that may collect in the French drain to be removed and analyzed. Presently waste, primarily in boxes, drums and cask liners, is stacked neatly in the trench... As the level of the waste reaches the design level, 2 m below grade, a layer of dry soil is added and allowed to filter down between the waste containers. When a trench is filled, it is covered with a cap of at least 0. 6 m of compacted native clay, followed by at least 0. 9 m of soil. The cap is graded to shed water and seeded with grass. The sump in each trench is monitored for at least 5 years and any subsidence in the cap is filled to maintain its water-shedding ability. Monitoring wells at the perimeter of the facility have not detected migration of nuclides after more than 15 years of operation.  4, fiche 2, Anglais, - monitoring%20well

Figure 6. 1 illustrates a typical open disposal trench at the Barnwell facility. The trench floor is sloped slightly and covered with a layer of sand to facilitate collection of percolating water in a french drain. A number of pipes allow any water that may collect in the french drain to be removed and analyzed. Presently waste, primarily in boxes, drums and cask liners, is stacked neatly in the trench, starting at the high end and progressing toward the low end. High specific activity waste is usually placed at the bottom of the trench. A separate narrower shielded trench is used at Barnwell for waste that has very high dose rates at the package surface. As the level of the waste reaches the design level, 2 m below grade, a layer of dry soil is added and allowed to filter down between the waste containers. When a trench is filled, it is covered with a cap of at least 0. 6 m of compacted native clay, followed by at least 0. 9 m of soil.  2, fiche 3, Anglais, - open%20storage%20trench
