  • The Importance of Quality NDT Equipment for Houston Companies

    Oil and gas infrastructure can suffer from high-temperature hydrogen attack (HTHA), where hydrogen dissociates and disbands within the steel under high temperatures, causing cracks and fissures. This is particularly concerning for refineries, and petrochemical plants in Houston, which is home to one-third of the nation’s energy jobs. Therefore, Houston-based producers need impeccable NDT ...

  • Battery Temperature Monitoring System

    Why is monitoring battery temperature important? Faults in a battery and it’s attached circuits can affect the temperature of the battery. Common faults that result in elevated battery temperature are ground faults, shorted cells, poor ventilation or inadequate cooling and lost regulation of charging. Battery temperature monitoring can identify these faults, and alert in ...

  • Explosive Growth in Alcohol-Based Hand Sanitizer Production

    Overview On January 31, 2020, the Secretary of Health and Human Services (“HHS”) declared a public health emergency related to the COVID-19 pandemic. Shortly thereafter, hand sanitizer began to disappear from U.S. retailers’ shelves, as anxious consumers (and, unfortunately, opportunistic hoarders and resellers as well) swept up all available stock. In the ensuing ...

  • Sub Slab Depressurization (SSDS) Installation- Case Study

    ERC was hired as the General Contractor to install a sub-slab depressurization system (SSDS) in a 533,000-square foot active facility.  The SSDS was designed by Hull & Associates to address the chemicals of concern (COCs) detected in the soil beneath the existing building slab.

  • Complex Health and Safety Plans (HASP)

    Health and Safety Plans (HASP) The most complex Health and Safety Plans (HASP) tend to be for hazardous waste projects or government contracts at high hazard locations. The U.S. Army Corps of Engineers (USACE) and the Department of Interior Bureau of Reclamation are good examples of government entities requiring very detailed HASPs. AtAtlantic Environmental, we have developed HASPs that ...

  • Toxicological Evaluation of the Chemical Oxidation Methods for Landfill Stabilization

    Abstract : As the stabilization criteria for landfill sites, only chemical criteria for the leachate discharges from the landfill sites have been used in Japan and many other countries. Recently, chemical oxidation has been developed as a method for the early-stabilization of landfills. However, by-products that are difficult to detect by chemical analysis can be produced by this method. ...

  • Toxicity Testing in Japan and the Use of Toxkit Microbiotests

    Abstract : Management of toxic chemicals in the aquatic environment is performed in Japan by setting environmental standards by law. Forty-nine chemicals are regulated and measured once a month at specific sites in rivers and lakes. Many of these chemicals are detected at various places in Japan, but in concentrations below the standard values. Dioxins, which are not regulated, have been detected ...

  • Automated Optimized TOC using PeCOD Technology

    Almost half of the population of Ontario relies on Lake Ontario for their drinking water. Source water from the great lake must be monitored and protected constantly to ensure chemical and biological agents remain below the accepted limits. Despite best efforts, it is possible that natural organic matter (NOM) can still exist in our drinking water. General methods of determining NOM are by ...
