Many fresh water sources have been degraded to toxic levels by the inclusion of industrial, agricultural, and human waste products that have been discharged into the closest body of water, accidentally or deliberately for many years.
Fugitive emissions can be a health concern during removal and disposal of mercury-contaminated material at remediation sites. Thus, remediation projects either indoors or outdoors often require on-site, real-time mercury air monitoring with a Tekran 2537. This assures permitted levels are not exceeded during waste processing and human exposure levels are below government regulated toxicity thresholds. Often multiple sites must be monitored continuously. The Tekran 1115 Multi-Port Sampler is the ideal tool for...
Contaminated soil and building-rubble can be efficiently treated with VacuDry technology, including a diverse range of toxic and hazardous substances. VacuDry units also have low emissions and low power consumption, making on-site treatment with our mobile units both economically and environmentally sound.
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...
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.
The contamination of soils as a result of prior chemical production can often be unpredictable and diverse. The majority of such pollutants will require an ex-situ treatment method. Many of our VacuDry units can be used for direct-feeding contaminated soils. To reduce the input amount for thermal treatment, the VacuDry units can also be used in combination with soil-washing plants: In this case, customers only feed the high polluted fractions and screened fines (e.g. below 10 mm), as well as the filter-cake from...
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.
In-situ geochemical fixation using a chemical reductant such as Remotox (calcium polysulfide) converts the soluble toxic metals into insoluble non-toxic compounds. Remotox has proven to be effective under a wide range of conditions. It is considered more stable and persistent than other reductants in subsurface environments, and is relatively safe to handle in the field and easy to apply.
We can help you achieve site closure and enable the sale or redevelopment of your site in a predictable timeframe with highly reliable results. This is made possible by: Our broad array of thermal remediation technologies, each tailored to the site-specific conditions and contaminants; Tested and proven field operations, processes, and teams; Expertise in designing projects to ensure outcomes without the need for further remediation; and, Our ability to assure a shorter project cycle and verification that goals...
Historically, landfills have been the most common method of organized waste disposal and remain so in many places around the world. Landfills are essential applications to ensure long service life and prevent soil pollution. In industrial basins, TenCate protection geotextiles guarantee the protection of the geomembrane against all risks of mechanical damages. A cost effective and environmental friendly solution to sort, treat and recycle waste.
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.
based in San Clemente, CALIFORNIA (USA).
BioSolve Pinkwater is used at major remediation and construction work-sites where excavation of contaminated soils may release noxious organic odors or hazardous VOCs. The dilute solution is sprayed directly onto newly exposed soil surfaces or stockpiles of contaminated material where volatilization is taking place. Used as an alternative to foam, Pinkwater creates a barrier that keeps vapors in the soil, allowing work to continue safely without disruption to workers or neighbors.
All construction affects groundwater and a water management plan will be required.
From deforestation to urbanisation, from holes to heaps and dams to drains, they all have an affect on the groundwater.
Deforestation causes an increase in the rate of run off of rainwater resulting in lower percolation of precipitation into the soil and a consequent increase in soil erosion leading to slope instability, hence land and mud slides. The increased rate of run off can cause small streams and large rivers to rise and...
