A recent study found elevated levels of radiation at a former dump turned busy community space, but experts say the public has little to worry about. Similar to other public parks, the Albany Bulb was formed on top of what was previously a landfill created along the eastern edge of the San Francisco Bayfront, just north of Berkeley. The main portion of the park, about 40 acres, is owned by Albany while the East Bay Regional Parks District owns the northern stretch of land leading up to the bulb and the state owns the southern portion. … Albany was ordered to survey the Albany Bulb for radiation by the San Francisco Bay Regional Water Quality Control Board after staff found a letter dated March 28, 1980, from Stauffer Chemical Company to the Department of Health Services that indicated the company had been disposing of toxic waste in the old landfill between 1960 and 1971.
