  • Fighting soil contamination with XRF

    Soil contamination Complying with new environmental regulations is a fast growing concern for companies and local officials tasked with ensuring that industries reduce pollution and clean up after themselves. It’s a particularly challenging issue when it comes to soil contamination It’s not always easy to detect as it silently contaminates crops and the ground water supply. XRF ...

  • Mobilization assessment and possibility of increased availability of PAHs in contaminated soil using column tests

    Surfactants are well known to increase solubility/mobility of hydrocarbons and can be used to remediate contaminated water and soil. We wanted to explore if Ivey sol R   106 used at less than the critical micelle concentration (CMC) could effectively mobilize PAH (polycyclic aromatic hydrocarbons) from contaminated soil. The first step was to establish a measurement technique. Hence, a ...

  • Solution blooming for fracking spills?

    Blooming salts may clean up after brine spills North Dakota's oil boom can have a salty side-effect. Wastewater from oil drilling and hydraulic fracturing – or fracking – is often laden with salts and can spill, contaminating soils. In 2014, for example, 42 such brine spills per week, on average, were recorded in North Dakota. Brine spills introduce so ...

  • Lucas County Port Authority Case Study

    Jeep Parkway – Toledo, Ohio Treated the soil in situ down to 20 feet. Removal of several unknown concrete structures, removal and disposal of more than 4,000 tons of PAH and heavy metal contaminated soil, collected over 200 soil samples and water samples, and moved 7,000 cubic yards of onsite borrow to fill and cap the ...

  • Case study - EPH in soil with diesel and home heating oils

    Sitelab’s UVF-3100 analyzer is a popular tool when excavating soils contaminated by fuel oils from underground storage tanks (USTs). These studies show the accuracy testing samples for Extractable Petroleum Hydrocarbons, EPH C11- C22 aromatic hydrocarbons. Samples are extracted in solvent using test kits and measured on the UVF analyzer’s EPH optics, calibrated to Sitelab’s PAH ...

  • Gulo Env reports site closure at Site remediated by Delta's BioLogix

    Delta had been contracted during the 2014 remediation at the well site to apply their bioremediation process to excavated and stockpiled soil contaminated with Fraction 2 petroleum hydrocarbons (F2 PHC). Soil sample results from a 2014 Phase II ESA showed F2 PHC concentrations ranging from 170 mg/kg to 1210 mg/kg, with an average of 586 mg/kg in the four samples from the disposal area. Delta was ...

  • Can I extend the range of the TPH in Soil kit by dilution?

    The pocket colorimeter kit by Hach offers an immunoassay method to measure TPH (Total Petroleum Hydrocarbons) in soil samples – a useful indicator of petrol pollution or contamination in soil. For areas of heavy contamination the range of the test can be extended by dilution during the soil extraction step. ...

  • The potentiation of zinc toxicity by soil moisture in a boreal forest ecosystem

    Northern boreal forests often experience forest dieback as a result of metal ore mining and smelting. The common solution is to lime the soil which increases pH, reducing metal toxicity and encouraging recovery. However, in certain situations, such as Flin Flon, Manitoba, Canada, liming has only yielded moderate benefits with some locations responding well to liming and other locations, not at ...

  • Progress Soil Sampling Results Collected from Phase 1 at SRSNE Superfund Site in Southington, Connecticut

    TerraTherm has recently completed its final progress soil sampling effort of Phase 1 at the Solvents Recovery Service of New England, Inc. (SRSNE) Superfund site in Southington, Connecticut. The site's total target treatment zone covers an area of approximately 74,195 square feet and an approximate volume of 47,298 cubic yards; with Phase 1 and Phase 2 each comprising approximately half the ...

  • Deadly Hexavalent Chromium in Soil

    Merging technologies will change over Hexavalent Chromium in soil to Trivalent Chromium, effectively stopping Hexavalent Chromium from becoming dangerously airborne or becoming even more deadly by migrating into the water table. There are three valences of Chromium: 1) Chromium—safe to humans, 2) Trivalent Chromium—safe and an essential element in humans and 3) Hexavalent ...

  • Phytotoxicity of trace metals in spiked and field‐contaminated soils: Linking soil extractable metals with toxicity

    Soil tests have been widely developed to predict trace metal uptake by plants. The prediction of metal toxicity however has rarely been tested. The study was set up to compare eight established soil tests for diagnosing phytotoxicity in contaminated soils. Nine soils contaminated with Zn or Cu by metal mining, smelting or processing were collected. Uncontaminated reference soils with similar ...

  • The investigation of arsenic and heavy metal concentrations in soil, water and crops around abandoned metal mines

    Soils, water and crops around abandoned metal mines can be contaminated by heavy metals from adjacent tailings and waste rocks accumulated during mining operations. The results indicate that the As, Zn, Cd, and Cr concentrations exceed the soil contamination standard in many soil samples of the nearby farmlands as well as the tailings sites. In the case of water quality, the As concentrations in ...

  • Microbial community structure and functioning along metal pollution gradients

    Toxic effects of heavy metals on soil microorganisms have been confirmed in a number of laboratory studies. However, most real‐field studies do not allow for strong general conclusions due to a range of problems, such as pseudoreplication and confounding factors, which are almost impossible to control for with the most commonly used polluted‐vs.‐unpolluted or random sampling designs. Effects ...
