Let the Phytoremediation Begin!

Friday, May 2nd, 2008

The Environmental Compliance Division at the Coast Guard base where I work is tasked with cleaning up decades worth of environmental problem areas on base and instituting sustainable operating procedures in the way the Coast Guard serves America. According to ARSC’s newsletter, we “recycled (kept out of landfills) 1330 pounds of toner cartridges in 2007″ and kept 1005 pounds of alkaline batteries from landfills by recycling, five times the amount of batteries recycled in 20061.

To clean up past bad practices, the ECD has started planting trees in contaminated areas, which draw pollutants out of the ground and prevent them from contaminating the water table. The fans on short poles visible amid the trees in these photos are drawing petroleum hydrocarbons out of the soil and atomizing them into the air.

From the information sign in front of this field:

From 1941 until 1991, the surrounding area was used as a fuel farm for aircraft refueling. The fuel farm consisted of multiple underground and above-ground storage tanks which were decommissioned and removed from the site. Evidence of a release was observed during the tank removal activities, resulting in impacts on subsurface soils and groundwater by petroleum hydrocarbons.

Phytoremediation was the selected remedy to control and contain contaminated groundwater migration and to remediate impacted soil and groundwater. Phytoremediation is an innovative and cost-effective technology that refers to the use of plant-based systems to remove, degrade, or stabilize environmental contaminants present in soil and/or groundwater.

Both poplar and willow trees have been planted across the site to remediate subsurface soils and groundwater. The use of both poplar and willow trees within a phytoremediation plot can capitalize on the favorable phytoremediation potential specific to each species.

The phytoremediation project is being performed in a combined effort with the United States Coast Guard, ARCADIS, North Carolina Department of Environment and Natural Resources, United States Geological Survey, and North Carolina State University.

  • Happy Space Day!
  • OHHHHH!!! BURNNNNN!!! 45 of Senator Inhofe’s “500 Scientists who Don’t Believe in Global Warming” (many of whom are TV Weathermen, Economists, and biologists), are shocked to find their names on the list, and have asserted that they do not dispute the consensus on Global Warming!!! Whoop! Whoop! Dittoheads are tarded!!! Ha! Ha! Nyah! Nyah! (Gets up and moons all dittoheads from behind the blog)
  • Never willing to let a little thing like factual veracity get in their way, the dittoheads are pretending they finally have a peer-reviewed paper that refutes global warming, but that is total horse pattoties too.
  • 37 years after engineering student Leon Chua described it mathematically, researchers at HP labs have built an electronics “missing link,” the memristor, which could lead to instant on computers with RAM chips that don’t lose their power state when shut off.

  • Academic cross-pollination. An NSF grant is funding a two-year project to better understand how scientists from different fields collaborate.
  • Like human infants, baby birds babble before they learn to sing.

  • Highly unusual survival gear.
  • Male seahorses are such Mr. Moms that they even go as far as being the ones impregnated.
  • Chinese jumping spiders prefer males that reflect UVB light.
  • Last seen in 1985, a scientists has rediscovered a bizarre-looking parasitic plant.
  • Last seen in 1896, scientists have rediscovered the greater dwarf cloud rat.

  • Republicans are outraged over an amendment slipped into last year’s energy bill that requires their taxpayer-funded vehicles be hybrids.
  • The FDA believes a blood thinner contamination that caused 81 deaths was deliberate.
  • Swearing in your native tongue is more cathartic.
  • Robotic bypass surgery is less invasive and requires a shorter hospital stay than the traditional method of cracking a person’s chest open.
  • What does it mean for something to be “alive?” English-speaking children have a harder time identifying living things because of the way our language is constructed.
  • A plastic surgeon is arguing that the finger regrown with dust, wasn’t seriously damaged in the first place and would have regrown on its own.
  • The Water + Life Museums complex in Hermet, California has become the first museum to break the LEED platinum barrier.
