M.R. and Barbara Hansen, Philip, discussed the possibility of Haakon County being the site for a deep borehole field test. The test would consist of boring an eight inch hole, down to a depth of three miles. Researchers would study the type of rock, chemistry of the water, at what depth do various types of rock appear, temperatures and other geologic data. It is possible a second drill with a 16 inch diameter hole could happen.
M. Hansen stated 10 acres would be needed for the test. A cement pad and a pit area would be constructed. When the test is finished the hole would be capped. The test is expected to last for five years.
M. Hansen said according to material he had obtained about the project, Haakon County businesses could see an estimated $1 million in revenue with the state seeing $10 million. The project would be overseen by the S.D. School of Mines and Technology, RESPEC, a consulting firm, and Battelle, a research firm.
Funny: I thought all that geothermal activity out Philip way would get in the way of conducting the Deep Borehole Field Test. But the Hansens apparently are hearing otherwise, and the Haakon County Commission, at least on first hearing, didn’t jump all over themselves to nuke the project based on any local fears that the project would bring nuclear waste to town.
The DBFT is intended to test the feasibility of digging holes more than three miles deep to dispose of nuclear waste. However, Battelle says no nuclear waste will come to Spink County, even if they do punch a big deep hole into our bedrock, since the Dakota Aquifer is too darn close for regulatory comfort.
Here’s Battelle’s press release in full:
Battelle, South Dakota School of Mines to Hold Open House Meetings in Tulare and Redfield
SPINK COUNTY, South Dakota – Battelle and a team that features the South Dakota School of Mines & Technology (SD Mines) and Rapid City-based RESPEC is considering sites in Spink County, South Dakota for scientific experiments in crystalline granite rock formations as deep as 3.2 miles below ground.
A final decision has yet to be made on whether the rock formations in this area are suitable for this Deep Borehole Field Test (DBFT), but Battelle and SD Mines will hold at least two open house meetings in Spink County to answer questions from the local community about this research.
The DBFT would continue the theme of South Dakota’s long history of pioneering underground research, such as the work being done at the Sanford Underground Research Facility (SURF), in Lead, SD, that explores dark matter and the early origins of the universe. The SD Mines also continues its work on the state-funded Shale Research Initiative. Similar to the work in Lead, the DBFT is funded by the United States Department of Energy (DOE).
The Field Test is intended to increase scientific understanding of the potential uses for crystalline rock formations. This includes the potential for disposal of certain types of radioactive waste, but also includes the potential for geothermal energy development. It is important to note that no radioactive waste will be used in this project.
The project also benefits South Dakota and Spink County, where it is projected to have a five- year, $1 million local economic impact and $10 million in the state.
While the rock (the Benson Block) seems to be ideal for scientific study, it will not be considered as a potential disposal site for radioactive waste. Due to the proximity of subsurface water (the Dakota aquifer) in the area, nothing beyond geological research can be done as part of this project. Regulatory standards for nuclear waste disposal are extremely demanding, and due to the close proximity of water to the granite, this site is not expected to meet those performance standards. The DOE has no plans to use the field test site for the disposal of radioactive waste. Additionally, it would be performed on private land where the owners do not wish to host a waste disposal site.
If scientists from SD Mines and Battelle determine that Spink County is suitable for geological study, the DBFT would investigate the type of rocks, the chemistry of the water, the depths of these rocks and water and the temperature deep underground. It will also provide a unique opportunity to gather other deep local geologic data and may have follow-on potential for geothermal research.
The project could last as long as five years, with drilling of the characterization hole taking six to eight months. After drilling, a series of tests will be done inside of the borehole that will last approximately another six months. After these tests are studied, a second deep borehole could be drilled to conduct further testing of the engineering and scientific characteristics of deep boreholes. Neither of these tests will involve radioactive material.
Spink County is one of several sites around the country that are currently under consideration for this research.
