At least 13 percent of the District's residents -- about 76,000 people -- have a drug problem, and city financing of programs to treat drug abusers has been "pitifully inadequate," according to a report released yesterday by researchers at the University of the District of Columbia.

D.C. government drug treatment programs have slots for 1,160 patients, far too few to serve the city's drug users, according to the report. There also are about 76,000 alcoholics in the city, but it is not known to what degree the two groups overlap, according to the researchers.

The report is the result of an 18-month evaluation of city-funded programs for drug treatment, education and referral. It said the programs have numerous problems, including laggard record-keeping, which prompted the authors to estimate some of the statistical findings in their report.

Emanuel "Dave" Chatman, chairman of the research group, which calls itself the Safe Streets Project, said its findings present "a sad, sad picture of the problem we're facing in the District . . . . We just have to spend more money {on treatment} to fight this."

At a news conference yesterday and in interviews, the researchers denounced Mayor Marion Barry, who they said had paid little attention to whether city-funded drug programs were working.

"What kind of war is fought when the general, the commander, does not know who his troops are, how much material they have, what actions they are taking, what success they have had or even where the troops are?" Chatman said at the news conference. The report does not criticize the mayor. It was released jointly by the Safe Streets Project and Barry's advisory committee on drug abuse.

Members of the Mayor's Advisory Committee on Drug Abuse had asked the Safe Streets Project to evaluate city-funded drug programs about two years ago, after learning that one program was receiving city funds but not providing services, said Annette Jones, chairwoman of the mayor's committee.

The team attempted to evaluate 37 drug treatment, education or referral programs that received funding from the District government last year. Four more were not included in the report because researchers were unable to visit them.

The report gave a majority of the programs high marks, and said District residents are getting "at least some services" for the $10 million the city spent on drug programs in 1989.

But the quality of those services varies widely, according to the report.

Among the problems cited by the authors was a failure by most treatment programs to determine what happens to clients after they have sought help.

In addition, one program that received more than $120,000 to operate a drug education project for school-age children was little more than a child-care center, the report said. And at another program in far Northeast Washington, an apparent drug dealer attempted to sell drugs to the team observers just outside the entrance to the building that houses the program.

The Safe Streets group frequently has criticized city response to the drug and homicide crisis. Chatman is a UDC accounting professor and president of its faculty senate.

It took UDC researchers six months to compile a list of city-funded programs that included the amount of money each received, locations of the programs and services provided, said Anne O. Hughes, another of the report's chief authors. "In some cases it was harder to locate the drug treatment program than it was to locate the nearest open-air drug market," Hughes said.

One of the programs that received the lowest ratings was a drug education and prevention program at Barry Farms Dwellings, in the 2600 block of Wade Road SE. Researchers found no one at the site on two vists. When they knocked on the door, "no one answered, and the glass in the door fell on us," according to the report. "Through the window, the place looked empty, abandoned and dilapidated."

"This program, while no doubt well-intentioned, doesn't treat drug abuse as such," the report said. "It seems to be a child-care facility or a community center."

Five drug treatment programs received the highest marks on the evaluation. They are:

ADERO House, a 25-bed treatment facility for teenagers on the grounds of St. Elizabeths Hospital.

Andromeda Transcultural Hispano Mental Health Center, a treatment and education center in the 1800 block of 18th Street NW.

Mary E. Herring Home, a men's treatment facility in the 700 block of Monroe Street NE.

Methadone Detoxification Center of Washington Hospital Center, a short-term drug and alcohol detoxification program at 100 Irving St. NW.

Rap Inc., a drug treatment program operated in the city's Forest Haven facility in Laurel.

The researchers said the estimate of 76,000 drug abusers in the city came from documents provided by the D.C. Council.
