Choose wrong, and you risk: Drainage failures Soil contamination Slope instability Costly remediation Let’s decode the science – and why partnering with a specialist geotextile suppliers ...
The subject site is a former dry cleaning facility in Northern Europe, where a large tetrachloroethylene (PCE) plume was impacting groundwater on and off-site. In 2017, CAT 100 and BOS 100® were applied as part of a large-scale remediation program. Currently, a 95% average reduction in PCE plume concentrations has been observed in the monitoring wells located in the areas targeted by the ...
“Well-functioning soil will retain, provide and recycle nutrients and water, and will support a diverse array of biota in the soil-plant system,” explains Jeff Schoenau, professor of soil fertility at the University of Saskatchewan and the Saskatchewan Ministry of Agriculture chair in soil nutrient management. ...
Introduction While in certain parts of the world Standard Penetration Testing (SPT) is the most widely used geotechnical soil investigation method, it has drawbacks. Cone Penetration Testing (CPT) is also a well-proven soil investigation method and is in many instances a more appropriate method than ...
The Moab Uranium Mill Tailings Remedial Action (UMTRA) site is a former uranium ore-processing facility managed by the U.S. Department of Energy (DOE) in collaboration with Lawrence Berkeley National Lab (LBNL). The highest remediation priority for the site is hauling and disposal of mill tailings. Additional efforts of the site are focused on remediation of a uranium plume on the edge of ...
Without taking the time to perform a soil analysis, it’s nearly impossible to determine what your soil needs to help your crops thrive. ...

Vista Clara’s Helios Core and Soil Analyzer (formerly named Corona) brings an unprecedented level of accuracy, flexibility and portability for robust measurements of hydrologic properties across a wide range of core sizes and lithology. ...
Well-Balanced Content Organic fertilizers offer a well-balanced blend of nutrient sources that are essential for the important microorganisms and earthworms living in the soil. These subterranean organisms are one of the many reasons for a fruitful and healthy soil structure. ...
Enriched soil, professional care, sufficient water, enough sunlight, and good quality fertilizers are the key factors to the high-quality growth of plants. ...
Ongoing site contamination Groundwater and soil samples were collected and analyzed in 2015 and 2016, producing analytical data which confirmed that widespread soil and groundwater contamination still existed at the site. ...

That is compared to water flow of surface drainage (when there is no tiling system) that may only take a few days. Well-drained, tiled soils, holds more water and reduce peak water flows. Soil and phosphorous are generally only lost through surface water. ...
Soil surface photolysis can be a significant dissipation pathway for agrochemicals under field conditions, although it is assumed that such degradation ceases once the agrochemical is transported away from the surface following rainfall/irrigation and subsequent drainage of soil pore water. ...
Over thousands of years, the carbon-rich remains of this productive ecosystem were slowly compacted and frozen into the soil. The amount of carbon stored in Arctic permafrost soil is estimated to be 1,500 billion tons — more than double what is currently in our atmosphere or four times as much as all of the forests on Earth. However, as temperatures in ...

Agency for International Development (USAID) traveled extensively in rural India and often stopped his car in the countryside to take soil samples. But he complained to me that he could no longer get good core samples: the soil was so dry it crumbled and fell out of his auger as he withdrew it. ...
It studied several areas in Crete which included Omalos and Elafonisos, both which are within the boundaries of Natura 20003 sites. Soil cores were collected from a large pond in Omalos and four smaller ponds in Elafonisos at regular intervals. Soils were spread on seedling trays in a greenhouse and emerged seedlings were identified. ...
To assess the movement of contaminants in the soil mass surrounded by near/subsurface waste repository, researchers have developed several mathematical and numerical modelling techniques. However, most of these techniques consider remolded state of soil mass, which fail to reproduce exact in situ conditions and also have used inactive salts as model contaminants. ...
The robust characteristics of composite materials ensure a highly sustainable solution that operates extremely effectively during the design life of the structure Geocomposites used in subsurface drainage applications usually consist of a three-dimensional polymer core, which acts as the water channel, coupled with geotextile filters which allow water to pass into the ...

Rather, the program consisted of the drilling of soil borings using continuous core drilling and screening the core sample at the surface. Screening methods included visual inspection of the core, the application of hydrophobic dye-impregnated fabric to the core sample, the collection of soil gas ...
