|
 | Abnormally high levels of methane gas in seafloor sediments could pose a major hazard to coastal populations within the next 100 years through their impact on climate change and sea level rise. Marine scientists have known for many years that biogenic methane (CH4) is generated in shallow seabed sediments on continental margins, especially in rapidly deposited muddy sediments with high organic matter content. Grassy sediments are found in river deltas, ... |

| Authors:
NAVAL FACILITIES ENGINEERING COMMAND WASHINGTON DC
|
| The goals of sediment remediation are to remove contaminated sediments from the environment, obstruct contaminant migration into the environment, and/or minimize exposure of ecological or human receptors to sediment contaminants. Contaminated sediments can be either left in place or removed, and often several cleanup techniques are used in combination or in sequence. In some situations, the best solution may be to allow natural burial and chemical weathering to permanently reduce ... |

| Addressing contaminated sediments at Naval facilities presents technical and managerial challenges. The state of the science is still evolving, as are the environmental regulations that apply to contaminated sediments. The Chief of Naval Operations (CNO) promulgated the "Policy on Sediment Site Investigation and Response Action" (CNO, 2002) to address ongoing sediment policy issues relative to the Navy's cleanup program. Likewise, Naval Facilities Engineering Command (NAVFAC) developed the "Implementation Guide for ... |

Michael G. Channell; Daniel E. Averett; ARMY ENGINEER WATERWAYS EXPERIMENT STATION VICKSBURG MS ENVIRONMENTAL LAB
|
| Sediments from the New York/New Jersey Harbor must be routinely dredged to maintain navigable water depths for shipping channels and berthing areas for commerce and safe navigation. Ocean disposal has historically been used as the primary alternative for disposal of dredged materials. However, the sediments that accumulate in the Harbor may contain contaminants at concentrations high enough to prohibit direct ocean disposal or beneficial use. This study evaluates solidification/stabilization (S/S) ... |

| Between 1959 and 1991, the Soviet Union engaged in an aggressive initiative to design, develop, and deploy nuclear weapons and nuclear power programs in support of national security objectives. The single-minded approach of the Soviet's nuclear effort, and the urgency of their developments rejected any considerations of cost: financial, human, or environmental. As a result, radioactive waste management received virtually no attention, and nuclear waste disposal was conducted in a ... |
