1993 Waters Symposium Proposals Proposals are solicited for the 1993 James L. Waters Annual Symposium, which will recognize the collabora­ tive work of groups involved in the invention, develop­ ment, and implementation of analytical instrumentation of established exceptional importance. Previous sympo­ sia have covered GC, atomic absorption spectrometry, and IR spectrometry. Proposals should include recom­ mendations for the analytical instrumentation to be rec­ ognized as well as names of inventors, entrepreneurs producing and marketing commercial instruments, and additional researchers at the forefront of the technology. Proposals should also recommend speakers who can au­ thoritatively address the invention, production, and use of the instrumentation. Proposals should be submitted by April 30 to Singh Manocha, PPG Industries, Glass R&D, P.O. Box 11472, Pittsburgh, PA 15238-0472.

Washing an Aquifer All manner of laundry detergents promise to get your clothes their whitest and brightest, but can a detergent actually save your drinking water supply? John Fountain, associate professor of geology at the State University of New York at Buffalo, has developed a process that uses surfactants, the active ingredient in laundry detergents, to literally wash toxic chemicals out of contaminated groundwater aquifers. The technique, called surfactant flooding, involves repeatedly pumping the contaminated water to the surface, adding the sur­ factants, and pumping the water back into the ground, allowing the treatment solution to pass through the con­ taminated area several times. In a recent field test near Ontario, Canada, the method was successfully used to eliminate the separate, insoluble phase of dense nonaqueous-phase liquids (DNAPLs) that form in aquifers where significant vol­ umes of organic liquids have been spilled. Fountain and

his colleagues walled off part of an aquifer that had al­ ready sustained chemical contamination. Injection and extraction wells were installed on opposite sides of the cell, and the aquifer was flooded with surfactants. After six months of treatment, the DNAPLs were removed. Fountain believes that the aquifer can now be treated with conventional procedures and restored to drinking water quality. An actual toxic waste site in Texas is undergoing sur­ factant flooding; results are expected this summer.

For Your Information Daniel W. Armstrong, Curators' Professor of Chemis­ try at the University of Missouri-Rolla, is the winner of the 1991 Isco Award in chemical separations. Armstrong is being honored for his research in developing chiral separation methods. A new brochure on quality is available from the Na­ tional Institute of Standards and Technology. Questions and Answers on Quality: The ISO 9000 Standard Series, Qual­ ity System Registration, and Related Issues (NISTIR 4721) provides answers to commonly asked questions about quality and quality systems. Included are brief descrip­ tions of the ISO 9000 standards and the conformity as­ sessment scheme of the European Community; a com­ parison of the ISO 9000 standards with the Malcolm Baldridge National Quality Award; contacts for industry assistance in getting information on current domestic and foreign standards, regulations, and certification ac­ tivities; and a list of standards-related and certification directories. To obtain a copy, send a self-addressed mailing label to Standard Code and Information Pro­ gram, A629 Administration Bldg., NIST, Gaithersburg, MD 20899 (301-975-4031). The American Institute of Chemical Engineers has just published the ninth edition of its Directory of Chemi­ cal Engineering Consultants. The volume lists con­ sultants alphabetically according to whether they are full time or part time consultants and what their spe­ cialties are. Cost is $15 for members and $25 for nonmembers. Contact the Publications Sales Dept., 345 E. 47th St., New York, NY 10017 (212-705-7657). The U.S. Environmental Protection Agency (EPA) has released Access EPA, a new 500-page directory that lists the agency's resources, services, and products. The directory's seven sections contain contacts and descrip­ tions of clearinghouses and hotlines, public information tools, rule-making procedures, databases, library ser­ vices, and records management programs. The directory is color-coded and has a comprehensive index. A form for comments is included for those who wish to make new entries or update information. To order the direc­ tory (stock no. 055-000-00378-5), send $18 to Mail Or­ der, Superintendent of Documents, P.O. Box 371954, Pittsburgh, PA 15250-7954. To order by phone, call 202-783-3238.
