Organoclay® RCM in Railroad Remediation
A rail yard in Utah has been in operation since the first transcontinental railroad reached the area in 1869. Four major railroad companies have used the rail yard for switching, maintenance of locomotives, and transferring cargo. A DNAPL tar plume was discovered running from the northern end of the yard under an adjacent highway and into a neighboring pond. HDPE geomembrane and Organoclay Reactive Core Mat from CETCO were used to remediate the site.

Versatility in Fiberweb Geocells
TYPAR® Geocells from Fiberweb are a unique confinement system that utilizes heavy-duty, well-established TYPAR geotextile fabric. The three-dimensional, honeycomb construction can accomodate multiple fill types. Folded into an accordion shape for easy transportation and a small logistical footprint, a TYPAR® Geocell unit is expanded on site and filled with a ballast material such as sand, stone, all soil types, mulch or other material. If desired, it can offer an excellent environment for re-vegetation. The three-dimensional cellular design allows for custom sizes, configuration and adaptability to a variety of terrains. No special training is needed to use the system.

Study: Greater Coal Ash Pollution in Water
A new study argues that U.S. coal ash disposal facilities are contaminating water supplies, both drinking and surface water sources, at a rate beyond what extensive US Environmental Protection Agency testing has found. Arsenic and other heavy metals have been discovered. The study, "In Harm's Way," was conducted by the Sierra Club, Earthjustice and the Environmental Integrity Project. It reveals 39 more polluted sites across 21 states, bringing the total to 167 sites across 34 states. The 270-page study is available here (PDF).
NAUE Receives Honor from Emergency Training Center
The expansive Smokey Hill Air National Guard Range near Salina, Kansas provides 34,000 acres for realistic environment training for both active and reserve military organizations. This unique facility includes a 156-acre zone for crisis response training. For the construction of a collapsed structure simulation, site coordinators sought a subgrade reinforcement material that would not require the addition of a separate nonwoven weed barrier. The Kansas Department of Transportation suggested NAUE America's Combigrid® GRK 5 20\20, a material with which KDOT has previous experience.
