Challenges in Classifying Remediation Waste - 4/27/2007 |
 "Challenges in Classifying Remediation Waste" appeared in the April 2007 edition of Commerce Magazine. The article, authored by Craig Gorczyca, Director of Operations and Waste Management Services for EWMA. There are many challenges today concerning the cleanup of contaminated sites. Some of the more obvious ones include time constraints, staying within established budgets and communicating with regulatory agencies to complete the cleanup. One of the not so obvious challenges concerning cleanups relates to waste classification – the characterization of wastes generated during remedial action for purposes of determining the proper manner and cost of disposal. |

New Uniform Hazardous Waste Manifest Required By USEPA - 9/6/2006 |
 Beginning September 5, 2006, generators of hazardous waste will be required by the United States Environmental Protection Agency (USEPA) and state environmental regulators to use a new uniform hazardous waste manifest. The uniform hazardous waste manifest was developed by USEPA to simplify and standardize hazardous waste manifesting throughout the United States. All previous hazardous waste manifest versions are obsolete after the implementation date, and will not be accepted by USEPA licensed disposal facilities or federal and state hazardous waste regulators.
The uniform hazardous waste manifest streamlines and standardizes the waste manifesting process via a number of important improvements, including:

DNAPL Chemical Oxidation Alternative Environmental Remediation Methods - 10/4/2006 |
 Traditional environmental remediation methods of cleaning up soil and ground water contaminated with chlorinated solvents, such as soil excavation and disposal or ground water pumping and treatment, are often prohibitively expensive or impractical due to site conditions. An alternative environmental remediation method used to cleanup chlorinated solvents, known as in-situ chemical oxidation, is growing in popularity and gaining industry and regulatory acceptance as it is proven to be a cost-effective, time-efficient and less intrusive alternative remedial method to achieve compliance with environmental cleanup standards.
In general, chlorinated solvent contaminants exist in the subsurface in multiple phases; vapor, dissolved, adsorbed and liquid, which is known as DNAPL. When the original chlorinated solvent liquid is lost into the subsurface, portions of it may volatilize and become a component of the air in the vadose zone (dry soil), dissolve into and become a component of the ground water, become adsorbed (molecularly bound or “stuck”) to individual soil particles, or remain as a liquid. |
