Several industries and industrial processes may contribute to soil and groundwater contamination. AdEdge Technologies has supplied filtration equipment for several remediation efforts to remove arsenic, lead, and other inorganic contaminants to meet state and federal mandates.
Sites with soil contamination often are also subject to contamination of the groundwater. Groundwater contamination can be very complex and a thorough understanding of the geology of the aquifer and contaminant sources is critical in planning remediation efforts. EnterVol offers C Tech’s proven technology within the ArcGIS environment.
Characterization of contaminated groundwater requires detailed monitoring to eliminate data gaps, improve predictive numerical models, and track remedial efforts. The Westbay System is a reliable, cost-effective technology for obtaining detailed information, enabling groundwater professionals to carry out comprehensive and defensible contaminant site investigations and long-term monitoring.
Regenesis Remediation Services (RRS) is a dedicated team of scientists and engineers whose primary function is to provide environmental engineering and consulting firms with specialized groundwater and soil remediation planning, design, verification and application services.

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...
Previous land uses or accidental spills can result in Volatile Organic Compound (VOC) contamination of soils. Volatile and semi-volatile compounds can then permeate through the soil and may persist for several years. This contamination can be traced and measured using our Soil Probes in conjunction with our VOC sorbent tubes. Soil probes are also useful in checking the effectiveness of remediation actions. This monitoring technique provides a cost-effective identification of hazardous gases.
The Sorbisense method allows for measuring the average concentration of substances in groundwater over a period of up to 1 month with only one sample.
The system provides methods for measurements in both unsaturated and saturated zone and provides access to dynamic boundaries of contaminants and more realistic risk assessments. For example, through direct measurements of seepage from contaminants and by continuous measurement of emissions from cropland.
Nanoremediation represents a modern method of treatment of environment polluted by chlorinated hydrocarbons, heavy metals, radionuclides and other contaminants. This technology started to be used tentatively in USA and it already takes place on various sites around the world at present.
Purolite is at the forefront in meeting the new challenges of purifying water for potable water use. We continue to develop specialized ion exchange resins and adsorbent solutions focused on reducing waste and operating costs. The wide variety of contaminants needing removal often requires a customized approach.
Chromium (Cr), Zinc (Zn), Copper (Cu), Lead (Pb), Cadmium (Cd), Mercury (Hg) and Arsenic (As) are among the most common metal contaminants found on remediation project sites. REMOTOX® (a Calcium Polysulfide Solution) precipitates these highly soluble metals as less soluble, less toxic metal sulfides. In the case of chromium, the metal precipitates as chromium hydroxide. See Elements and their Potential In-Situ Precipitates.
Effective against a wide range of heavy metals, radionuclides, chlorinated...
The use of H2O2 to chemically oxidize the contaminants into mineralized products (CO2 , salts, and readily biodegradable organic fragments) offers a number of advantages over these current treatment methods.
Benefits of Soil Decontamination by Chemical Oxidation:
The reagent used (H2O2) is inexpensive, readily available, and has as its reaction products water and oxygen;
The chemistry of the process (Fenton's Reagent) has been known for over 50 years and its applicability to a wide variety of contaminants is...
Today bioremediation is successfully used as soil– and groundwater remediation technology. Many bioremediation systems, both in-situ as ex-situ techniques, usually result in considerable cost savings. Since the beginning of the 1980’s both in-situ and ex-situ bioremediation projects have been successfully completed worldwide through the use of preselected and adapted bacteria. QM Environmental Services supplies a range of microbial, bioactivator and nutrient products and gas delivery systems for the use in both...
Enhanced anaerobic biodegradation is the practice of adding hydrogen (an electron donor) to groundwater and/or soil to increase the number and vitality of indigenous microorganisms performing anaerobic bioremediation (reductive dechlorination) on any anaerobically degradable compound or chlorinated contaminant. The most commonly targeted chlorinated groundwater contaminants are primarily used in industry as degreasing agents and include: Perchloroethylene (PCE), Trichloroethylene (TCE), Dichloroethylene (DCE),...

Helping others clean up the earth by clearing up brownfield remediation odors. Helping others clean up the earth by clearing up brownfield remediation odors. Brownfield remediation consists of removing large amounts of soil that have been saturated with tar, oil or other contaminating substances. Not only dangerous to handle, the disturbed soil is often infused with very unpleasant and in some cases potentially nauseous odors.
