New gel barrier technique may help prevent spread of underground hazardous waste

By Jeffery Kahn

A new gel-based technique that could seal hazardous waste and prevent the spread of chemicals has been field tested by Earth Sciences Division researchers.

Collaborating with the Bechtel Corp., LBL demonstrated the feasibility of the concept in January at a Los Banos, Calif., sand and gravel quarry--a site with complex subsurface conditions similar to those at Hanford, Wash. If the development effort continues to be successful, the technique could substantially reduce both the financial and environmental costs associated with the country's thousands of hazardous waste sites.

To immobilize waste, the LBL team drills a string of wells around and beneath the perimeter of the area that is to be contained. Then, they inject a fluid that is able to permeate the ground before gelling and forming an impermeable barrier that surrounds the contaminated site.

Earth scientists Karsten Pruess and George Moridis liken their technique to the creation of an underground isolation chamber. The researchers stress that each site is unique and cleanup strategies will vary. However, they believe their approach is a vital supplement to today's standard cleanup method.

"Up until now," said Moridis, "the country has been fighting a losing battle. Huge areas can be contaminated by just a few gallons of hazardous fluids, and once they get into the ground, contaminants are very difficult to strip from the soil. Unfortunately, the state of the art of cleaning up these sites is the same as it was 30 years ago--we dig the soil out and truck it to a hazardous waste site."

The costs and limitations of this approach have handicapped the nation's cleanup efforts. Thousands of contaminated sites have been identified but few have been cleaned up. Over time, groundwater can cause the contamination to spread. Meanwhile, nearby water supplies, rivers, residential areas, and human health can be jeopardized by these delays.

As the project has moved from the lab to the field, LBL project chemists John Apps and Peter Persoff have worked with chemical companies including Dow Corning, DuPont, and Philadelphia Quartz Corp. to refine the performance of the gel barrier fluids, all of which are environmentally benign.

Bechtel Corp. handled the operational aspects of the recent field test. Moridis and Pruess say they chose the quarry site because the underground there is such a jumble, and a severe test for any gel barrier fluid.

"The problem is heterogeneity," Pruess says. "Natural environments have an intrinsic variability that you cannot anticipate or control. Companies like Bechtel that inject grout into the ground--to strengthen dams and foundations, or keep water out of construction sites--run into this all the time. At one site, a grouting contractor injected over 1,000 sacks worth of cement slurry down a hole, and every bit of it completely disappeared. Twenty feet away, they were unable to inject more than a few dozen sacks."

For the recent field test, LBL injected two fluids, a colloidal silica and a polysiloxane fluid. Several days later researchers excavated the plumes, slicing the earth away to reveal how well they had managed to penetrate and saturate the uneven ground.

The colloidal silica performed satisfactorily but the polysiloxane exceeded expectations. Bechtel specialists who have been injecting materials into the ground for two decades say the material did something they had never seen before.

"Not only did we see a uniform, almost symmetrical plume," reports Moridis, "but everything was grouted uniformly, everything from very large pores to the small pores in clays. Nobody has seen a material that grouts clay before. As a matter of fact, it's supposed to be impossible."

When injected into the earth, polysiloxane has a viscosity similar to water. A catalyst causes it to turn into a strong, rubber-like gel and controls how quickly this occurs. Soil chemistry, which can cause a compound to gel prematurely, does not seem to affect polysiloxane. The product, a silicon-chain polymer, was developed by Dow Corning for LBL.

Precisely how long a gel containment would last in the earth--a relatively short time or a millennium--must still be determined, although the life expectancy of similar products is 30-50 years. During remediation, even a barrier with a lifetime of months can be useful, helping to contain or redirect groundwater flows.

Besides their use at hazardous waste sites, gel barriers have other potential applications. These include lining and capping landfills, stabilizing slide-prone slopes, and preventing soil liquefaction in earthquake-prone areas.

LBL researchers say the next step is a larger scale test to show the ability to contain the area around an underground storage tank. The ongoing effort is sponsored by the Department of Energy's Office of Technology development (headed by Clyde Frank) under the In Situ Remediation Integrated Program (led by Jef Walker and Mary Peterson).

White House Science Advisor John Gibbons flatly rejected the proposal for a Department of Science advanced by House Science Committee Chairman Robert Walker, R-Pa. (see Newswire, April 14). "Let me be clear about one thing--this administration unequivocally opposes the creation of a Department of Science," Gibbons told a colloquium sponsored by AAAS. "The genius of U.S. science policy to date has been its recognition that pluralism of support and diversity of performance allows the crucial freedom of inquiry that unleashes creative spirit of our world-class researchers and their students." He also ridiculed the Republican-controlled House for threatening to take a "meat axe" to federal R&D programs, including DOE's. He defended the Department's promoting of energy efficiency and its signing of CRADAs with private industry. "If industry does not invest (in a CRADA) there is no deal--industry is picking the winners and losers, not government," Gibbons said. "Economists, investors, technologists and industrialists understand and widely support this activity. In their rush to judgment, some members in the new Congress don't want to be confused with the facts."


Senate Majority Leader Robert Dole of Kansas has publicly called for the abolishment of DOE. The Energy Department, he argues, "would function better as an agency within the Department of Defense." To this end, he has formed the Senate Republican Task Force on Elimination of Government Agencies. In addition to DOE, Dole has also called for the elimination of the departments of Education, Housing and Urban Development, and Commerce: "The most ineffective, burdensome, and meddlesome departments in the federal government," he said in a speech last week in Kansas.


In answer to the apparent desire of a Republican Congress to deeply slash funding for applied R&D programs, DOE has released a report that claims American consumers have saved "billions of dollars" from energy efficiency technologies developed at the national laboratories. Entitled, "Success Stories: The Energy Mission in the Marketplace," the 22-page document lists such technological developments as the low-emissivity windows and high-energy electrolytes and batteries from LBL; high-compression refrigerators and freezers; catalytic exhaust converters for auto engines; light water reactors; atmospheric fluidized-bed coal combustors and low-polluting coal-fired boilers; mudpulse telemetry for the drilling industry; and photovoltaic electricity cost-reductions for solar cells. Said Energy Secretary Hazel O'Leary: "We support high-risk and technically challenging R&D projects. Not all of these ventures make it to the marketplace but when they do, they pay off big." Copies of the report can be obtained by calling (202) 586-3900.


Victor Perez-Mendez of the Physics Division was quoted in the April 17 edition of the New York Times in an article about computerized dental radiography. The topic was new systems for reducing the exposure of dental patients to x-rays. The article cited Perez-Mendez's development (through a CRADA with Air Techniques of New York) of electronic sensors to replace dental film (see Currents, January 20.).

Earthquake Preparedness: Getting ready for the Big One

Preparation has big payoff

By Don Bell, Emergency Preparedness Coordinator

It's April, and, in California tradition, time to "prepare" for the big one. In reality, most of us don't prepare, but merely think about it and procrastinate, or think that there's little we can do to protect ourselves and families.

But, there are things we can do to protect ourselves--simple things that don't take a lot of time, effort or money. Call it a big pay off for a little effort, a common theme in these times of doing more with less.

What do we mean by "big pay off"? A general rule of preparedness is that there is a pay back ratio of 100 to 1. For example, for every minute you spend stocking food and water in your emergency supplies kit, you'll avoid 100 minutes of effort trying to find potable water after the earthquake. A similar comparison can be made to dollars invested. Suppose you spend $10 and one hour bracing your china closet at home and it doesn't topple and break during the earthquake; you've saved the furniture and its contents. But supposed you didn't make that investment; it could cost you a thousand dollars or more to replace and repair it, and untold time lost.

So what are the high pay-off actions that you can take now? Following are some (but not an all) of the things you can do at home and at the Lab:


  1. Make sure your water heater is fastened down. This costs little and could prevent your house from burning down.

  2. Prepare a disaster supplies kit. See the checklist on page 3 or contact LBL's Emergency Services Office at X6554 or X6016. To stock the basics could take as little as an hour with little or no investment.

  3. Prepare an emergency plan for your family. Discuss with all family members the location of supplies, utility shutdown procedures, emergency phone numbers and who to call should the family be separated when disaster strikes. This costs only 30 minutes of your time.

  4. Safeguard or prepare copies of important papers such as insurance policies, titles and deeds and personal documents such as birth certificates and marriage licenses. Store copies in a safe location other than your home.


  1. Spend about 10 minutes reading your building's emergency plan. See your building manager. If you don't know who he or she is, call X6554 and ask. The plan includes instructions for credible emergencies at LBL.

  2. Spend about 5 minutes getting familiar with the emergency pages near the back of the LBL phone book. You'll find information about what to do during and after an earthquake. You'll also find information about the 22 emergency rescue boxes located throughout the Lab.

  3. Spend two minutes writing down the following number and putting it in your purse or wallet: 800-445-5830. This is the Lab's emergency status information announcement. If there is an emergency affecting the Lab, the recording will provide employees emergency information such as whether to report to work, road conditions or special instructions.

If you accomplish the above, you'll have a great start in preparing yourself and your family for the next earthquake. There's more you can do to ensure a greater degree of protection. Those seeking information should call the Laboratory Emergency Services Office for free brochures and training. Don't procrastinate; don't read this same article next year and say "I should get ready." Start today.

Earth Month

Out of the belfry, into the Lab and maybe our hearts

By Mike Wooldridge

Christine Scott never met a bat she didn't like. She came to LBL on April 12--with four furry flyers in tow--to tell why.

"A lot of people think that the only good bat is a dead bat," she said. "I don't think that's very fair."

Insectivorous bats provide eco-friendly pest control--some bats can eat more than 600 mosquitoes an hour. Fruit eaters are important pollinators and seed dispersers. (Like mangoes? Thank a bat.)

But because of cave-curious humans and pesticides, many bat species may be heading the way of the condor and the spotted owl. More than half of the 22 bat species in California are under consideration as threatened or endangered by the U.S. Department of the Interior.

Scott is director of animal care at the California Bat Conservation Fund in Marin County. The center nurses injured bats back to health and sends experts to schools to lecture on the benefits of bats. She spoke as a part of the Lab's Earth Month activities.

Scott's mission is to dispel the B-movie myths about bats that many people grow up with: That they are simply blind "rats with wings" out to suck our blood.

"Blind as a bat" is a myth, she said. Most bats have eyesight as good as or better than that of humans. Sonar complements their eyesight for quick maneuvering at night, and keener species can distinguish a single human hair in mid-flight.

On the evolutionary tree, she said, bats are closer to humans than to rodents. Bats, apes and humans are the only creatures with opposable thumbs. Bats are smart and have personalities, just like cuddlier higher mammals.

The danger of blood-sucking bats is practically nil north of the U.S.-Mexican border, she said. The three vampire species--out of a thousand species worldwide--live in Central and South America. Two prefer chickens; the third feasts on larger farm animals, but might attack a person if there isn't a sheep, goat or donkey around.

Wildlife experts traditionally haven't helped the animal's image. It used to be standard procedure to kill any bat brought in to a refuge, for fear that it might be rabid. But studies show that only one in a thousand bats carries rabies, Scott said--a frequency on par with other wildlife. (Those that do get the disease lose their ability to fly, which is why you should never touch a grounded bat.)

Through education, she says, people are learning. Farmers are finding out that fruit bats are their friends, not the crop-stealing nuisances they had thought. In addition to pollinating, most fruit-eating species eat over-ripe fruit, which it is no longer of use to farmers and can serve as a host to fruit flies.

Where is the best place to find bats in California? Go where the bugs are, Scott says. On summer nights, bats leave their caves, trees and barns to fly over lakes, ponds, and other standing water, where there is a healthy supply of mosquitoes and other insects. Bats hibernate in winter.

For anyone interested in attracting bats to their home, the Bat Conservation Fund offers blueprints for "bat houses," similar to the bird kind but with vertical slats inside for roosting.

The Bat Conservation Fund can be reached at (415) 456-6598. n

Serving the Nation

Visitors to the 22nd floor of Oakland's Kaiser Building, which houses the University of California's executive offices, are treated to a colorful overview of the three UC-managed labs (LBL, Livermore, and Los Alamos). The display, entitled "Serving the Nation Through World-Class Science and Technology," includes photos of each director, as well as scenery and program shots from each lab. The lobby area contains displays on each of the UC campuses. UC President Jack Peltason (above) said of the display: "This is an impressive showcase for the work the labs do and the value they represent. It's also symbolic of our new partnership with the labs and the Department of Energy for lab management, and our efforts to strengthen and increase interactions among the campuses and labs--all in the spirit of continued public service."
