Scientists put the chill in drill to clean up waste

By Mike Wooldridge, MAWooldridge@lbl.gov

Researchers in the Earth Sciences Division have put a cool twist on the underground drilling used to clean up toxic waste sites. They have invented a drill that blasts super-cold nitrogen gas as it bores, creating frozen holes that won't collapse even in the sandiest of soils.

Nitrogen is injected down the drill's center pipe and exits through nozzles near the spinning drill bit. At -196 deg.C, the gas freezes difficult soils rich in sand, gravel or ash long enough for workers to insert stabilizing metal casings into the holes before the ground thaws.

George Cooper in Earth Sciences developed the technology with Rafael Simon, a UC Berkeley graduate student.

The cryogenic method should be valuable to researchers trying to clean up contaminated grounds at many industrial facilities, closing military bases, and Department of Energy weapons laboratories, where loose dirt has often made it difficult to drill holes that do not cave in.

Boring holes in the earth is usually the first step in assessing contaminated areas. Soil samples taken from the holes tell scientists the types of pollutants that are present as well as their distribution. Drilling is also critical for removing contaminants from the ground, which can involve pumping pollutants out with groundwater or boiling them out with injected steam.

Unfortunately, cleanup experts at many facilities often find themselves faced with crumbling soils that will not hold their holes. "It's also no coincidence that you find difficult soils at weapons labs--they were built on land of little commercial value," Cooper says. "In the west this means sandy deserts. In the east this means agriculturally poor land, which often has sandy soil."

Drillers at contaminated sites are at a particular disadvantage since they can't use substances such as "drilling muds," the clay-based goo that is used to help stabilize bore holes. Drilling muds can complicate the cleanup effort by changing the permeability of the soil or spreading the contaminants further.

One location where soil collapse has been an issue is the nuclear cleanup site in Hanford, Washington, which sits on layers of loose gravel and sand. Cave-ins have hampered attempts to analyze the soil beneath storage tanks that were used to store radioactive waste.

"People have had difficulty drilling vertical holes at Hanford, and those are the easy ones," Cooper says. "To get to the soil beneath the tanks, you need to drill holes at an angle. These are even less stable."

The cryogenic drilling should allow scientists to drill the difficult holes at Hanford and other problem sites such as the Savannah River site in South Carolina, Idaho National Engineering Laboratory, and the Oak Ridge Reservation in Tennessee.

The method performs well in other problem soils as well, such as clay-rich soils that clog drill bits. Clay soil is frozen hard by the nitrogen gas and is crushed by the drill bit into rock-hard chips, which are blown out of the hole by the gas pressure.

"The nitrogen gas also has an advantage when it comes to sampling soil for monitoring since the freezing locks the pollutants in," Cooper says. "Methods that use water may wash some of the pollutants completely away. You may seriously underestimate the level of pollution."

Engineers have occasionally used cryogenic techniques in the past when working with loose soil. Construction crews may pipe in liquid nitrogen to freeze and stabilize the surrounding ground when working underground near buildings. This is the first time such a super-cold idea has been put into practice with drilling.

T E I D: Department provides integrated information delivery

By Diane LaMacchia

A new department has been created within the Information and Computing Sciences Division.

Called the Technical and Electronic Information Department (TEID, pronounced "tide"), it combines the staff from the former Technical Information Department with reference librarians and computer experts to create an integrated information delivery system.

"Whether you're creating it, trying to find it, or you need it delivered," TEID will make it happen, says acting department head Sandy Merola, who is also deputy director of ICSD.

In building the new department, Merola says, "we have tried not to give up anything that already existed, and we have also tried to add things."

For example, TEID is putting its computer expertise together with the creative abilities of graphic artists and photographers to create multimedia documents. As journals become accessible on-line, TEID will be able to deliver the necessary elements, such as video, hypertext, and sound.

This effort includes technical support to enable employees to use the computer software Mosaic and the World Wide Web to publish information on the Internet. To do this TEID is collaborating with scientists and support staff in other divisions and with the Public Information Department, which is responsible for the content of LBL's "home page," the vehicle for sharing information about LBL with users of the World Wide Web.

Merola says TEID is also working on an integrated conference support service. This will combine the preparation of presentation materials and the coordination of logistics and comfort for conference participants with the ability to download satellite links, run video conferencing, and provide on-line projection.

The conference service will involve the efforts of two other ICSD departments: Communications and Networking Resources for video conferencing with other laboratories, and Computing Services, which will provide workstation support for presentations.

LBL lecture series: Science and Technology in a Competitive World

Fumio Kodama, professor of Science, Technology and Industry at the Research Center for Advanced Science, University of Tokyo, will be the next speaker in the LBL lecture series Science and Technology in a Competitive World. Kodama will speak on "Emerging Patterns of Innovation: Sources of Japan's Technological Edge" at noon on Monday, May 23, in the Bldg. 50 auditorium. All employees are invited to attend.

Smooth sailing


PHOTO CAPTION -- It was smooth sailing at the Advanced Light Source as the third undulator was installed in its new berth, sector 9 of the ALS storage ring, on Friday, May 6. The 25-ton structure had to be moved from the assembly area on the experimental floor to above the storage ring, then lowered into place through the top of the shielding. In the last stage the clearance between the undulator and the surrounding equipment was less than 7 mm. The 8-cm-period undulator will generate light for Beamline 9.0, scheduled to begin operation in August. A large group of people contributed to the successful design and construction of the device, including the ALS insertion device and experimental systems groups, and a host of mechanical and electrical engineers and technicians.

Skin cancer screening

Appointments are being taken at Health Services (X6266) for the Skin Cancer Screening Clinic, to be held from 8 a.m. to noon on Friday, June 3, at Bldg. 26. Patients will be seen by a physician, and all questionable findings will be examined by Dr. Edward Ringrose and Dr. Elizabeth Ringrose, both Berkeley dermatologists. Please plan to take the LBL shuttle to your appointment as parking is very limited.

LBL faculty to retire under VERIP-III

The following LBL employees have elected to retire effective July 1, 1994. These staff members also hold UC faculty positions, and completed the academic year before taking advantage of the University Voluntary Early Retirement Incentive Program, VERIP-III. We wish them our best.

New job hazards questionnaire

Have you ever wondered which environment, health and safety training you're required to take? Or which courses apply to your work?

The EH&S Division has just developed the Job Hazards Questionnaire to enable each employee to identify required or recommended EH&S training courses. The questionnaire is part of the Lab-wide training database system, now called STAR (System for Training Assessment and Records).

All personnel, including managers, staff, students and participating visitors, working at LBL for more than three months, are required to complete the Job Hazards Questionnaire. All new personnel must complete it within the first month of employment or assignment.

The questionnaire asks employees and guests about the materials they use, equipment they operate, hazards in the vicinity of their operations, and special assignments they may have with ES&H implications. "Yes" answers lead to required and recommended training courses.

When answers are entered in the STAR database, a list of required and recommended training courses, called a Training Profile, is generated. If a course has already been taken, the Profile shows when it was completed and when any retraining is necessary. The Training Profile also lists any other courses the employee or guest has taken.

The questionnaire can be answered on paper copy or on-line (on the VAX) in Focus using the Toolkit (you must have a CSA account).

In the near future, each division will distribute copies of the questionnaire with instructions to employees and participating guests. This will coincide with the annual Performance Progress Review process.

All current employees must complete the questionnaire during the initial implementation phase. Answers must be entered into the database by Sept. 30. Each division will be responsible for data entry for its employees and guests.

The questionnaire requires employees, supervisors, and matrix supervisors, if applicable, to review, sign and date the form. The completed questionnaire will be filed in the employee's personnel file. Thereafter, the questionnaire must be reviewed, updated as needed, and signed annually.

If you have any questions about the Job Hazards Questionnaire or the training database system, STAR, contact Mona Bernstein at X5258 or Nancy Humphrey at X6611.

CHELYABINSK WORKSHOP:

The Lab's Russian-American Center for Contaminant Transport Studies, headed by the Earth Sciences Division's Chin-Fu Tsang, hosted the second ever Chelyabinsk Workshop this week. Russian and American scientists discussed issues related to waste problems at the nuclear facility of Chelyabinsk in the South Ural region of Russia. Chelyabinsk is the most polluted of Russia's radioactively contaminated sites. The workshop provided a foundation for a planned field test program at the site scheduled for July.

LBL PEOPLE:

Occupational health nurse Judy Kody of the Health Services Department has been inducted into the East Bay Chapter of Sigma Theta Tau International Honor Society of Nursing in recognition of her leadership and marked achievements in the field of nursing.

Corporate Challenge

Employees with fleet feet take note: the San Francisco Corporate Challenge is coming, and you still have three months to get in shape.

David Jump of the Energy and Environment Division ran the 5K foot race last summer and is looking for others to join him this year on Thursday, August 11. He hopes to represent LBL in proud fashion, perhaps wearing specially-designed T-shirts.

Held in cities throughout the United States, the Corporate Challenge is the largest participatory athletic event in the country, according to its sponsor, Chemical Bank. The San Francisco race snakes through the city's downtown Embarcadero area.

Call Jump for more information at X4679.

Reception to honor awardees

LBL will hold a reception at 11 a.m. on Monday, June 6, outside the Advanced Light Source to honor, for their recent awards, LBL Associate Lab Director Glenn Seaborg, Art Rosenfeld of the Energy and Environment Division, Heinz Heinemann of the Materials Sciences Division, and Robert Bergman of the Chemical Sciences Division. All employees are invited to attend. Refreshments will be served.

In March, Seaborg became the first living person to have an element named in his honor. Element 106, first created at LBL in 1974, was officially named "seaborgium." Seaborg also received the George C. Pimentel Award in Chemical Education for his "outstanding contributions to the education of the world's citizens."

Rosenfeld was honored in January with the Sadi Carnot Award, one of three Energy and Science Technology Awards given by DOE. Rosenfeld was recognized for his many accomplishments in the fields of particle physics and energy efficiency. In April, Rosenfeld was named senior advisor to DOE's Assistant Secretary for Energy Efficiency and Renewable Energy.

Heinemann won the Homer H. Lowry Award in Fossil Energy, another of the DOE Energy and Science Technology Awards. His many contributions to the field of fossil energy research include the identifcation recently of a catalyst that converts methane into hydrocarbons without producing carbon dioxide.

Bergman won a 1993 E. O. Lawrence Award in December for his important contributions to organometallic chemistry, most notably for the discovery of a class of metal complexes with important commercial applications for the oil and coal industries. n

LBL hosts Project Interface Science Fair

LBL hosted a science fair on April 30 for Project Interface, an after-school Mathematics and Science Enrichment Program serving Oakland high school students.

Approximately 30 high school students from King Estates, Havenscourt, Oakland High, Fremont, Westlake, St. Elizabeth, and Castlemont schools participated in the event, the first science fair sponsored by Project Interface.

Marva Wilkins, outreach coordinator in the Center for Science and Engineering Education, coordinated the event with Project Interface Director Nimat Shaheed. Wilkins welcomed the students to the Lab and introduced them to LBL research. Presentations were made by Jimmie Johnson of Engineering, who lectured on levitation, and Rollie Otto, Head of CSEE, who discussed the building of new elements.

The students presented their projects to judges, family, and friends in the cafeteria during the afternoon. An awards ceremony followed.

Other LBL staff contributing to the event's success were Mollie Field of Conference Coordination, and Carl Cooper and Jim Rusting of Bus Services. Dan Kurn of Energy and Environment served as a judge.

Cafeteria closure

The LBL cafeteria will be closed for remodeling from Friday, June 3, through Friday, June 10 (note the change in dates from an earlier announcement). There will be a catering truck in the cafeteria parking lot to handle breakfast and lunch during this period. The cafeteria will be open for business again on Monday, June 13. Canteen Corporation apologizes for any inconvenience.
