What Is This Fact Sheet About?
The U.S. Environmental Protection Agency (EPA) is working to clean up contamination at the Greenwood Chemical Superfund Site, located in Newtown, Albemarle County, Virginia. This fact sheet gives you information on the clean-ups for soil and ground water at the site. It also provides an update of recent site work, details what happens next, and tells you how to obtain further information on the site.
We are working with the Commonwealth of Virginia and the U.S. Army Corps of Engineers to remove contaminated soils. When the cleanup begins, approximately 11,000 cubic yards of soil will be removed and taken to another state for treatment and disposal.
The Army Corps of Engineers designed the plans for the cleanup and will supervise the actual work. The Corps will also advertise the job and solicit bids from qualified contractors to do the work. We delayed the work while trying to get the parties responsible for contamination to pay for the cleanup. However, we did not receive good faith offers from those parties. Therefore, we will use federal Superfund money to conduct the cleanup.
The Commonwealth of Virginia recently signed a Superfund State Contract. This contract specifies that the State will contribute 10% of the costs of the clean-up action. This contract has now been signed by both EPA and the State. Therefore, federal monies can be used and site work can begin.
We hired a firm that is currently designing the pump and treat system that will be used to clean up contaminated groundwater and pond water. This summer, residents can expect to see workers installing, sampling, and testing groundwater wells onsite. All of the groundwater used during pump testing will be discharged into the on-site ponds for eventual treatment. After completing the design study, the contractor will submit to EPA the final plans for the water treatment system (which will be located onsite).
What Is Happening With Deep Soils?
New Technology Tested
We are continuing to look into the deep soil contamination onsite. These soils are located far below the surface and are unable to be removed by digging them up. One new method we have tested on deep soils is bio-venting. This involves forcing air into the contaminated soils. The air helps microbes in the soil break down contaminants at a faster rate than would naturally occur. Early sampling results showed lower levels of contaminants in the soils. However, while the results are promising, it does not mean that bio-venting will be selected as the final clean-up option.
Focused Feasibility Study
In order to fully investigate clean-up options for deep soils, we will conduct a study to analyze other potential clean-up actions that can be used to treat the deep soils. Results of the bio-venting will also be included in the study.
Once the study is complete, we will issue a Proposed Plan. The plan will list all of the possible clean-up options we evaluated. It will also highlight our preferred method to treat deep soils. The community will have a chance to review and comment on the options during a public meeting and public comment period. All comments and questions on the Proposed Plan will be considered before we select a final clean-up method.
