For weeks, San Francisco residents and officials have been slamming the Navy for waiting nearly a year to disclose that a radioactive<\/a> heavy metal was found on the former Hunters Point Naval Shipyard, a Superfund site the federal government has been cleaning up for decades.   

On Monday evening, Navy officials took a rare step during a community meeting full of angry residents<\/a>: They apologized.<\/p>\n\n\n\n

The Navy took 11 months to report the discovery of plutonium 239, used primarily in nuclear weapons and power plants, to its regulatory partners, which include the U.S. Environmental Protection Agency, the California Department of Toxic Substances Control, the Regional Water Quality Control Board and the California Department of Public Health. San Francisco health officials have told the Chronicle that they weren’t informed about the finding until last month. <\/p>\n\n\n\n

\u201cI have really thought about the situation that\u2019s occurred \u2026 on this issue, we did not do a good job,\u201d Michael Pound, the Navy\u2019s environmental coordinator who for the past two years has been overseeing the toxic cleanup at what is now a development called the San Francisco Shipyard, told a room full of residents who gathered at 451 Galvez St. for a briefing from the Navy on the incident.<\/p>\n\n\n\n

\u201cWe were too busy being engineers and scientists and trying to think through (the data) and did not put ourselves in the community\u2019s shoes,\u201d Pound said. \u201cI can\u2019t undo what\u2019s been done but \u2026 we need to do better.\u201d<\/p>\n\n\n\n

But for community members who for years have asked for transparency in a cleanup already marked by fraud<\/a> claims, the meaning of the discovery was clear: The Navy and its partners had failed them, once again.<\/p>\n\n\n\n

Hundreds of\u00a0homes have already been built<\/a>\u00a0at the Shipyard, and thousands more are planned for the site but can\u2019t get underway until the cleanup is complete.\u00a0<\/p>\n\n\n\n

Pound described the sample as an \u201coutlier\u201d and attempted to calm concerns: The airborne heavy metal sample measured as a dose of 0.04 millirem \u2014\u00a0 \u201cfar below\u201d levels that could pose a health risk to workers and the local community.<\/p>\n\n\n\n

And yet, that level was higher than the \u201caction level\u201d agreed upon by the Navy and its regulatory partners in the plan that governs the Superfund site\u2019s cleanup, and triggered a reevaluation of the air sample by a Navy contractor. <\/p>\n\n\n\n

\u201cWe then had a non-detect,\u201d said Pound, describing a situation in which Navy officials were perplexed by two different results for the same sample: one that showed elevated levels of plutonium 239, and one that did not. <\/p>\n\n\n\n

\u201cThis was concerning for us,\u201d admitted Pound, adding that the datasets were next sent to a third-party laboratory for analysis. That laboratory\u2019s procedures were subject to an audit, which concluded that \u201cthe plutonium results are valid\u201d and that the sample showing the exceedance was an outlier.<\/p>\n\n\n\n

Pound said it\u2019s still unclear why there was a higher level of plutonium 239 than expected. The contaminant was detected in an area of the Shipyard known as Parcel C, which sits below a hill where new homes were built a decade ago, and near a community of artists that occupy studio spaces in buildings at the Shipyard. It was discovered as the Navy\u2019s contractors were \u201cgrinding\u201d and \u201cmoving\u201d asphalt on Parcel C. But the asphalt, which Pound said was placed around 2015 \u2014 decades after irradiated ships that were brought to the shipyard after atomic bomb tests could have contaminated it \u2014 was an unlikely source.<\/p>\n\n\n\n

Pound said that the Navy received the \u201coutlier result\u201d in March and that the laboratory analysis was completed by April. Between May and September, the incident was further investigated \u2014 it took months before an audit of the laboratory\u2019s procedures was finalized, he said. <\/p>\n\n\n\n

Ahimsa Porter Sumchai, medical director of the Hunters Point Community Biomonitoring Program, which screens residents<\/a> and workers of the area for toxic metals and other hazardous chemicals, was angry about the situation. She pointed out that the Navy had a real-time dust monitor placed on Parcel C, meaning the Navy should have known about the contaminant sooner.<\/p>\n\n\n\n

Sumchai described the Navy\u2019s failure to disclose information about the plutonium 239 sample after it became aware of it, as \u201cproof of concealment and fraud.\u201d<\/p>\n\n\n\n

Steve Castleman, an attorney specializing in environmental law, pointed out that the Navy has assured the community in the past that parts of the Shipyard were cleaned to regulatory standards\u00a0\u2014 and yet,\u00a0radioactive objects<\/a>\u00a0have continued to turn up.\u00a0<\/p>\n\n\n\n

\u201cIn Parcel A, you found a (radioactive deck) marker you claimed could never be there,\u201d Castleman said. \u201cIn Parcels B and C, you found another deck marker and a glass shard that had high concentrations of radioactivity that you also said could never be there. In Parcel G you found 62 strontium 90 samples that exceeded the cleanup goal. \u2026 And you ask us to trust you?\u201d<\/p>\n\n\n\n

State and federal regulators tasked with overseeing the Navy\u2019s activities at the Shipyard said Monday that they were also kept in the dark. <\/p>\n\n\n\n

\u201cUnfortunately the EPA did not learn about this until Oct. 23. We were sent an email with the details. I have adequately expressed to Michael Pound how we feel about that. We were not happy about the late notification,\u201d said Michael Collins, a remedial project manager with the Environmental Protection Agency. <\/p>\n\n\n\n

But Collins said the EPA agrees with the Navy\u2019s assessment that the plutonium 239 sample did not pose a \u201chuman health risk\u201d even though the agency had yet to fully verify the Navy\u2019s data as of Monday, having only received it last week. <\/p>\n\n\n\n

\u201cThey haven\u2019t given us everything we asked for or require,\u201d he said, when pressed by community members about the timeline.<\/p>\n\n\n\n

Michael Howley of the California Department of Toxic Substances Control said the state agency \u201cdid not learn about this until about the same time as the public.\u201d<\/p>\n\n\n\n

\u201cOur agencies have not been able to participate in the Navy\u2019s review to date,\u201d Howley said. \u201cWe have prepared our own information request to make sure we can validate the Navy\u2019s analysis.\u201d <\/p>\n\n\n\n

Others, too, said they were still waiting for the Navy to share all of its data supporting how it arrived at the conclusion that residents are safe.<\/p>\n\n\n\n

Castleman, the attorney, confronted Navy officials: \u201cWhen are you going to provide the data to the public?\u201d <\/p>\n\n\n\n

Danielle Janda, the Navy\u2019s base closure manager for the Shipyard, said the Navy was still finalizing its report on the incident\u00a0\u2014 but promised it is working to \u201cget it up on our website shortly.\u201d<\/p>\n\n\n\n
