  • Incorporating site-specific analytical data and machine learning to predict environmental site conditions

    EnviMetric makes intelligent predictions about the extent of groundwater contamination even when there is no available analytical data regarding contaminant concentrations. Factors such as the site location, release type, property use, and geologic setting are very predictive of how large a groundwater plume will be. EnviMetric uses all this available information to make data-based predictions of ...

  • Bioremediation of Naphthalene and Methylnaphthalene Isomers

    Petrox bioremediation accelerates the removal of naphthalene and isomers of methylnaphthalene.  These petroleum compounds are often slow to remediate due to their low volatility and strong affinity for absorption onto soil particles.  The remediation rate of these compounds is slower than BTEX compounds.  They often also rebound as the absorbed phase solubilizes following removal ...

  • How to set up a groundwater monitoring test site

    When it comes to groundwater monitoring, testing the water often requires the creation of a borehole at the test site to reach the water below. The process of creating a safe and secure site for everyone involved can sometimes be a lengthy process. The size of the borehole, which drill to use and the response zone are just a few of the considerations that will need to be taken into account during ...

  • Health Hazards at Construction Sites

    When we think of construction sites, especially those involving infrastructures like bridges, tunnels, and highways, we usually picture heavy equipment like bulldozers, excavators, steamrollers and heavy-duty dump trucks. These visible signs of construction activity tend to make us think more about safety problems than of health hazards. But the reality is that there can be just as many, if not ...

  • How to Remediate under an Intersection with Horizontal Wells

    Roadway intersections within urban settings are arguably some of the most challenging areas for subsurface remediation. Many consultants tasked with remediation of challenging sites such as these become frustrated by the inability of a vertical remediation system to influence the area of concern and/or they are anxious that they will not efficiently bring their clients’ sites to ...

  • Train derailment prompts contaminated land investigation - Case study

    On March 30th 2015 a long freight train, transporting a variety of goods including lumber and chemicals, wound its way through the state of Mississippi. At around 5pm, part of the train failed to negotiate a curved portion of the track in a rural area near Minter City, resulting in the derailment of nine railcars, one of which leaked chemicals onto agricultural farmland and woodlands. Emergency ...

  • How Not to Lose Cadmium While Measuring?

    Today cadmium finds a better usage than a hundred years ago. For example, metal cadmium plating is used for anticorrosion coatings that are more stable than zinc, nickel and tin-plated. Cadmium plating of steel parts gives greater resistance to corrosion, especially in sea water. About 20% of cadmium goes to the manufacture of cadmium electrodes used in ...
