Environmental justice advo cates say ATSDR's findings sub stantiate their claims that disad vantaged communities, often located near sites, face dispropor tionate risks. Poor, minority com munities will welcome the find ings, said Rabbi Daniel Swartz, associate director of the National Religious Partnership for the En vironment, which works on envi ronmental justice issues. "It's good to have concrete evidence to back up people's anecdotal tales."
ATSDR's work will help state health officials answer the pub lic's concerns and determine if states need to take additional ac tions, said Alice Stark, who directs the New York State Department of Health's Bureau of Environmental and Occupational Epidemiology. The agency's findings, however,, do not permit a general state ment about the risks a Superfund site may pose. "It's not a question anyone can -say yes or no to," Stark said. "Each site is different."
ATSDR does not have enough information to prove Superfund sites caused the health effects researchers observed, stressed Lybarger. Nor can it tease out the chemicals that pose the greatest risk, because people sue normally exposed to mixtures. However, the study shows associations that merit future research.
The findings warrant attention, but the health community needs to know the basis of comparison for its risk evaluation, said Jerry Poje, director of international programs and public health at the National Institute of Environmen tal Health Sciences (N1EHS). Haz ardous waste sites may present a small-to-moderate risk to the vast majority of people, he said, but some vulnerable subpopulations may be particularly affected by these sites because they already face other health problems.

many of the chemicals and chem ical mixtures found at Superfund sites, he said. Suk called on Congress to increase health re search funding as it reauthorizes Superfund.
However, Nandan Kenkeremath, majority counsel for the House Commerce Committee, is skeptical about ATSDR's findings. "Our genera] view is that we are wasting money on excess hypo
thetical and imaginary risks," he said. Superfund sites often are in industrial or other areas where people are exposed to toxic agents from many sources or in poor communities where lack of ' medical care.could explain dis ease incidences, he added.
Nevertheless, the House's pro posed Superfund reauthorization bill (H.R. 2500) would give ATSDR more authority in some cleanup decisions, such as remedy selec tion. "Our bill takes a very strong stance on public health driving Superfund decisions," said Kenkeremath. The Republican-led House felt comfortable increasing ATSDR's authority because in sev eral cases the agency has gone to a Superfund site, tested children's blood-lead levels or other prob lems, and found a significantly lower health risk than EPA's risk assessments predicted.
ATSDR has a broad range of responsibilities that include eval uating the nature and extent of contamination at Superfund sites, evaluating the existence of expo sure pathways, determining the size and susceptibility of exposed populations, and conducting health studies that compare disease and mortality data with ex posures to site-related contami nants. --PATPHIBBS
