Otis Air National Guard Base - Environmental Issues

Environmental Issues

Military operations in the early years at Otis AFB included the use of petroleum products and other hazardous materials such as fuels, motor oils, and cleaning solvents and the generation of associated wastes. Consistent with practices of other industries at the time, it was common practice for many years to dispose of such wastes in landfills, dry wells, sumps, and the sewage treatment plant. Spills and leaks also occurred. These activities have resulted in serious impacts to the Upper Cape’s groundwater resources. As a direct result of the threats from waste plumes in the groundwater, much of the water supply in the surrounding area was converted from wells to municipal water sources.

In towns near the Air Force's PAVE PAWS radar at Otis Air National Guard Base, there was significant concern about possible adverse effects on health of humans resulting from PAVE PAWS radiation. In 1978, the EPA and the US Air Force School of Medicine decided that no such threat to human health was plausible. At the request of local residents, in 1979, two panels formed by the National Research Council reviewed existing data on the radar and on comparable systems: an engineering panel and a biomedical panel. Neither panel found any cause for concern, but the panels did recommend additional studies. The local communities' concerns peaked again in the late 1990s, and another National Research Council panel studied not only previously available data, but also engineering measurements newly gathered by the Air Force, epidemiological data gathered by local public health authorities, and the results of studies on various other systems. The report of this latest NRC panel, issued in 2005, available from the National Academies Press both online and in hard copy, finds no evidence for adverse health effects from PAVE PAWS. There are nearby clusters of certain types of cancer, but as is often true in cluster studies, there are so many confounding effects that any possible effect due to PAVE PAWS is indiscernible. Further, no plausible causal link to PAVE PAWS on health of nearby residents has been discovered. Of scientific interest is the possibility that growth rates of vegetation close to the radar and exposed to the direct radar beam may possibly be retarded, but no plausible connection of that possibility to effects on human health is known.
