fractured bedrock

Application of biobarriers for groundwater containment at fractured bedrock sites.

The structural geology of the area is relatively complex with highly to intensely fractured bedrock.

Contaminated fractured bedrock will need to be addressed.

An area can have layers of sandy soil, fractured bedrock, clay, or hardpan.

Characterization of trichloroethylene contamination in the fractured bedrock at the Smithville site.

• Queen's University: biological barriers in fractured bedrock.

Many plant species grow on sites perched on exposed fractured bedrock in dry shallow soils.

In permeable or porous materials, such as sands and well fractured bedrock, the water table forms a relatively horizontal plane.

Or it could have been directly channeled to the fractured bedrock and into the well through a direct breach in the soil above the bedrock.

Contaminated groundwater within the fractured bedrock beneath the site is difficult to extract using traditional vertical wells, particularly where existing buildings restrict access.

The use of point dilution techniques for determining groundwater velocity in fractured bedrock, Smithville, Ontario.

The term "mega-regolith" is often used to describe the heavily fractured bedrock directly beneath the near-surface regolith layer.

By analogy with the Moon, frequent impacts produced a zone of fractured bedrock and breccias in the upper crust called the megaregolith.

The fractured bedrock aquifer is covered by thin, often permeable overburden and is generally quite susceptible to contamination.

The area to be flooded and the area under the dam footprint are characterized by faults and "highly" fractured bedrock.

Do not use this type of manure storage over sand, gravel, or fractured bedrock since leakage could cause pollution of underground water supplies.

In 1982 diesel fuel migrated from a well lease site into underlying fractured bedrock contaminating the groundwater-bearing zone approximately 30 m below ground surface.

Removal of the tailrace rock plug will require instream blasting followed by excavation of the fractured bedrock material.

The earth itself was ruptured in places, with jagged scarps of fractured bedrock jutting from the ground beside open chasms and fissures.

Below this true regolith is a region of blocky and fractured bedrock created by larger impacts, which is often referred to as the "megaregolith".

The deep confined flow system includes flow within the glaciolacustrine sands and gravels, till and fractured bedrock.

The ice flow may have exploited highly fractured bedrock along the margin of the Willoughby pluton or joint surfaces within the pluton.

Beneath the finely comminuted regolith layer is the megaregolith, a layer of highly fractured bedrock many kilometres thick.

An aquifer is a natural underground layer of porous, water-bearing materials (sand, gravel, fractured bedrock), sometimes capable of providing a water source.

Coarse-grained sand, gravel, and fractured bedrock aquifers are particularly susceptible to widespread transport of viruses and other pathogenic organisms.
