I’ve never thought too much about this, I guess I’m still waiting for my first geotechnical assignment in Hawaii! But if you bring soil samples into the continental USA, they must go through a heat treatment at their port of entry. In the latest GeoComp Corporation newsletter, Gary Torosian from GeoTesting Express, GeoComp’s lab testing arm, describes how their firm’s certification with the U.S. Department of Agriculture allows them to accept soil samples without the required heat treatment. They can receive, and test the samples and then upon completion of the testing, they heat treat the soil, sample containers and any effluent generated from the testing process to safely dispose of any potentially harmful organisms. Something to keep in mind for those cushy projects in Hawaii or the US Virgin Islands or something. (Photo by Eric K. Veland on Flickr)

In this contributed article by Lis Smith of DeWind, she describes a project to construct a soil/bentonite slurry wall around the perimeter of a site which was once a pre-World War II munitions factory. The groundwater contamination, difficult ground conditions and special project requirements were a perfect application of the DeWind One-Pass Trenching technology.

[Editor] The Delaware Department of Transportation (DelDOT) had a major problem on their hands after a bridge on I-495 was leaning…one side of the bridge was 18 inches higher than the other. The culprit? A pile of fill adjacent to the bridge was loading soft soils beneath. So what do you do about it? In this contributed article by Dennis M. O’Shea, bridge engineer in the FHWA Delaware Division Office, he describes the problems faced by DelDOT, the causes, and how they fixed it.
