Contaminated Groundwater Applications

The advantages of paste thickeners in tailings circuits have been well-established for most minerals. The type of paste thickener underflow generally used for surface stacking of tailings is called “thickened tailings.” Thickened tailings are a suspension of solids which are relatively non-settling and non-segregating and which have a higher concentration and viscosity than that of conventional tailings. Common applications include a thickener with underflow pumps that are typically centrifugal and...

C Tech is known worldwide for our innovative approaches to Soil contamination modeling. Soil contaminant data can often span 6 orders of magnitude or more. Extremely high gradients coupled with limited budgets make it very challenging to develop reasonable models of contaminant distributions. EnterVol incorporates C Tech’s proven expert systems to conquer the challenging process of developing reasonable volumetric plume models. EnterVol provides the ability to present reams of complex geologic and environment...

Stabilization and Containment of Airport Fluids. Airports take careful measures to capture, contain, and treat deicing fluid and fuel runoff. In capturing the deicing fluid, the GEOWEB system stabilizes the pavement aggregate base layer and stores the deicing fluid in the contained aggregate voids. Stormwater containment basins built with impervious liners prevent infiltration of jet fuel and other contaminants into the groundwater. The GEOWEB system covers and protects geomembranes from puncture and solar...

Contaminated groundwater sites worldwide are engaged in regular sampling of monitoring wells at a typical cost of $1,500 per well-sampling event. On most sites, many wells are redundant or geostatistically insignificant and can be decommissioned.EVS-PRO and MVS`s Well Decommission module analyses all available data and quantifies the impact on site assessment quality associated with removing each well. The impact of removing a well is quantified in terms of its impact on the geostatistical plume extent.During...

Temperature is an important factor in streams ecosystems. Heat tracers have been used to characterize contaminant transport, infiltration rates and energy exchange with groundwater, the atmosphere and radiation. The dynamics of these complicated water bodies is also affected by seasonal and diurnal patterns making characterization particularly challenging. Utilizing temperature measurements that capture spatial and temporal variations at stream ecosystem interfaces provides a mechanism for detailed characterization...

Single wall underground steel oil storage tank is easy to be corroded by micro-organisms, and the degree will be more and more serious if the tank storages liquid fuel in decades. Moreover expenses to control leakage pollution are quite expensive. How to find out and deal with issues in time has raised the public`s attention. While Double Wall Fiberglass Tank can be widely used in the oil storage and transportation field because of its advantages of high structural strength, double protection of environmental and...

The Algal Turf Scrubber technology offers an exciting new opportunity for advanced levels of treatment for domestic wastewaters. With the high cost of nonpoint source nutrient control, hydromentia-point-sourcesecondary or AWT treated wastewater can be polished with an Algal Turf Scrubber unit, providing cost-effective nutrient load reduction. For sprayfield and rapid infiltration basins where nutrients often contaminate groundwater and result in impairments to adjoining surface waters, pre-treatment with an Algal...

Challenges in landfill operations: Many organic compounds contained in landfill leachate are hardly degradable and the nitrogen content in leachate is high compared to the carbon content. This makes leachate from landfills and rubbish dumps difficult to treat adequately at municipal wastewater treatment plants. Municipal treatment plants also cannot adequately remove the heavy metals contained in the leachate. As a consequence, wastewater treatment plants enforce strict regulations on leachate heavy metal content.
