remnants of a former weapons program, not in Iraq but at Fort Detrick in Frederick, M d . O n a r e m o t e p a r t of the installation, which once produced chemical and biological weapons, the Army has dug up 113 bacteria-containing vials but no chemical or biological warfare agents. Most ofthe vials contain live bacteria, including nonvirulent strains of anthrax. About 12 years ago, m o n i t o r i n g wells in remote Area B-ll of Fort Detrick detected high levels of trichloroethylene (TCE) and tetrachloroethylene (PCE) in groundwater. TCE, a cleaning solvent, and PCE, a degreasing agent, were detected at levels hundreds of times

above EPAs maximum contaminant level (MCL) of 5 ppb. W h e n the Army tested 33 nearby residential wells, it found seven with unacceptably high levels of these potential carcinogens. At the Army's expense, these seven homes were connected to other water supplies. The Army does not have an inventory of what was dumped in AreaB-11's four unlined pits. But the Army suspects that T C E and P C E leaked from corroded drums dumped into the pits and then leached into groundwater. Actual excavation of the 4 0 0 acre site to remove toxic chemicals and medical and lab waste buried from 1955 to 1970 began two years ago. "This is the only excavation of this magnitude at Fort Detrick," Army spokesman Chuck Dasey says. It is expected to cost more than $25 million.

Modernization Of EPA Data System Lags

T

he Environmental Protection Agency's effort to modernize its computer system for tracking companies' compliance with water pollution permits is falling behind while costs escalate, says the agency's inspector general. EPA and 18 states use the system to track water pollution permits and enforcement and inspection at some 64,000 facilities regulated under the Clean Water Act. The computer system, managed by EPA's Office of Enforcement & Compliance Assurance, is 21 years old and suffers data-quality problems. In addition, it does

field, workers in protective suits have removed 2,005 tons of hazardous waste and contaminated soil from Pit 1, the largest pit. In addition to vials of live Brucella melitensis, Klebsiella pneumoniae, and Bacillus anthracis, workers have also removed more than 40 drums, some containing herbicides, and 50 gas- and liquid-containing cylinders. Traces of dioxins found in agent orange, a defoliant used in the Vietnam War, have been detected in Pit 1, but no vials of viruses have been found, even though Fort Detrick actively made viral as well as bacterial biological weapons until 1969. Tainted soil and waste from Pit 1 has been processed and, if pathogen-free, sealed in containers and shipped to a hazardous waste disposal site in Texas. EPA Region I I I spokesman David Sternberg says, "Current monitoring indicates that no contamination above the MCL for TCE and PCE is reaching beyond the property line, but significant contamination remains inside the base at Area B." Cleanup of the other three much smaller pits began in early May. Once restored, by early next year, Area B-ll will be used for military training.— LOIS EMBER

now stands at Sept. 30, 2006. Estimates of the costs to complete the modernization "recently increased dramatically," the report says. It does not provide dollar amounts because the estimates are considered proprietary. The report recommends new cost estimates, quick completion of a project management plan, and the setting of "realistic" deadlines. To ensure that water pollution regulators get the data they need, the report warns against delaying \ completion or cutting back the scope of the project. — CHERYLHOGUE
