After the Storm: Co-Produced by the U.S. EPA and The Weather Channel
|
The show highlights three case studies—Santa Monica Bay, the Mississippi River Basin/Gulf of Mexico, and New York City—where polluted runoff threatens watersheds highly valued for recreation, commercial fisheries and navigation, and drinking water. Key scientists and water quality experts, and citizens involved in local and national watershed protection efforts provide insight into the problems as well as solutions to today's water quality challenges.
After the Storm also explains simple things people can do to protect their local watershed-such as picking up after one's dog, recycling household hazardous wastes, and conserving water.
The program is intended for educational and communication purposes in classrooms, conferences, etc.

Green Remediation: Best Management Practices for Excavation and Surface Restoration
|
This fact sheet is one of a series describing best management practices (BMPs) for green remediation, which holistically addresses a cleanup project's (1) energy requirements, (2) air emissions, (3) impacts on water, (4) impacts on land and ecosystems, (5) material consumption and waste generation, and (6) long-term stewardship actions. BMPs can be used for sustainable removal or cleanup activities at contaminated sites under Superfund, corrective action, underground storage tank, and brownfield cleanup programs. Many opportunities exist to reduce the negative impacts of excavation, which commonly include soil erosion, high rates of fuel consumption, transport of air-borne contaminants, uncontrolled stormwater runoff, offsite disposal of excavated material, and ecosystem disturbance. Decisions regarding excavation processes and targets affect follow-up land and surface water restoration strategies as well as ultimate land use.

Crozet Phytoremediation
|
This video highlights EPA's Green Remediation initiative, which considers the environmental effects of the remedial strategy early in the process, and incorporates options to maximize the net environmental benefit of the cleanup. From the selection and design of the remediation technology, to the management of on site activities, to the use of energy conservation and alternative sources of clean energy, Green Remediation helps save natural resources and taxpayers money. In this presentation, a former orchard in Crozet, VA is cleaned using Phytoremediation and incorporates many of the Green Remediation goals.

Biosolids Recycling: Restore, Reclaim, Remediate
|
Sewage treatment results in wastewater being recycled to the environment, but the solids removed from wastewater can also be processed and turned into a nutrient rich fertilizer. Today's primary use of this fertilizer is to restore overworked agricultural soils, but research by the USDA and the USEPA/ERT has now opened the way for use of biosolids to reclaim lands destroyed by mining.

FootPrint
|
Posted: January 2, 2009
|
FootPrint is a simple and user-friendly screening model used to estimate the length and surface area of benzene, toluene, ethylbenzene, and xylene (BTEX) plumes in ground water, produced from a spill of gasoline that contains ethanol. Ethanol has a potential negative impact on the natural biodegradation of BTEX compounds in ground water. The primary objective of the software is to predict the increase in surface area of the plume of BTEX compounds or any other chemical of concern (COC) due to the presence of ethanol in ground water. FootPrint estimates the area of a plume of particular BTEX compounds that are contained within two biodegradation zones: 1) a zone that is immediately adjacent to the source, where ethanol is present in high concentration and no biodegradation of the BTEX compounds (or other COC) is allowed, and 2) a second zone, where the ethanol concentration is negligible due to the natural biodegradation of ethanol in the first zone and biodegradation of the BTEX compound (or other COC) contributes to attenuation in concentration of the BTEX compounds. FootPrint is based on the modified version of the Domenico model (1987) published by Martin-Hayden and Robbins (1997). This model is an approximate analytical solution of the advective-dispersive solute transport equation with first-order decay. The model of Martin-Hayden and Robbins (1997) was further modified in FootPrint to allow zero-order decay as well (see Appendix B of the user's manual for details). As a result, FootPrint can independently describe the natural biodegradation of ethanol and/or the BTEX compound with either a zero-order rate constant or a first-order constant. FootPrint can also be used to estimate the surface area of the plume and the concentration at any given point within the plume when the COC is decaying at a constant rate (first- or zero-order) in the absence of ethanol.

Environmental Technology Verification (ETV) Program Materials Management and Remediation Center
|
Posted: December 19, 2008
|
The ETV Program is pleased to announce the addition of the new Materials Management and Remediation (MMR) Center. Battelle Memorial Institute has been awarded the cooperative agreement to operate the new MMR Center. This center will verify materials management technologies, including for recycling, beneficial use of waste materials, recovery of useful components of waste, and treatment to minimize disposal requirements (e.g., containment, volume, cost). The MMR Center will also verify technologies to remediate contaminated land and ground water, such as is found at Superfund sites and other properties where industrial or commercial activities have resulted in a legacy of hazardous constituents that limit future use of the property.

Comparison of Pumped and Diffusion Sampling Methods to Monitor Concentrations of Perchlorate and Explosive Compounds in Ground Water, Camp Edwards, Cape Cod, Massachusetts, 2004-05
|
Posted: December 19, 2008
|
Laboratory and field tests were conducted at Camp Edwards on the Massachusetts Military Reservation on Cape Cod to examine the utility of passive diffusion sampling for long-term monitoring of concentrations of perchlorate and explosive compounds in ground water. The results of laboratory tests in which diffusion samplers were submerged in containers filled with ground water containing perchlorate, RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine), and HMX (octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine) indicate that concentrations inside the diffusion samplers equilibrated with concentrations in the containers within the 19-day-long test period. The results of the field tests indicate generally good agreement between the pumped and diffusion samples for concentrations of perchlorate, RDX, and HMX. The concentration differences indicate no systematic bias related to contaminant type or concentration levels.
