NASA Ames workers worry over Superfund site's toxins

Amateur disease map points to rare cluster of ALS cases at NASA Ames

Following news that several employees had developed a rare neurological disease, the NASA Ames Research Center is facing a new wave of concern that hazardous substances linked to the nearby Superfund sites could be affecting its workers' health. The recent scare has prompted a new round of testing for toxic chemicals in old buildings at Ames, but health officials say harmful substances have stayed within safety limits.

NASA Ames is situated at Moffett Field on federal property with underground aquifers known to be contaminated with industrial solvents, including TCE, left by the area's former semiconductor factories. While hazardous to human health, the toxic groundwater plume has been viewed as a manageable problem under a regimen of regular testing and cleanup administered by the U.S. Environmental Protection Agency.

But fears persist among NASA employees that low amounts of hazardous chemicals that fall below federal safety thresholds could be behind suspicious diseases affecting co-workers. Federal Occupational Safety and Health Administration officials as well as Ames employees' union representatives are seeking an epidemiological study to determine whether the toxins bear any correlation with at least seven reported cases of ALS, also known as Lou Gehrig's disease.

The new concern over a possible link emerged last year when the federal OSHA officials received two complaints from an anonymous NASA employee alleging that workers housed in an aging building were experiencing sickness from a chemical smell. Following these complaints, a NASA engineer provided his own independent research showing a significant number of workers over the last 15 years had contracted ALS.

It remains a medical mystery as to what causes non-genetic ALS, which accounts for more than 90 percent of cases. The disease is almost always fatal and there's no known cure, but it is extremely rare -- only about two people out of 100,000 per year are affected by it.

The research, which was described to a Voice reporter, indicated that seven employees who worked out of a cluster of buildings on the north side of the Ames campus had contracted ALS since 2000. Six of those employees died from the disease. About 2,500 people work at the Ames campus, making it statistically significant that so many cases of ALS appeared in one group.

The independent research was spearheaded by NASA Space Flight project manager Stevan Spremo, who said he began looking last year for disease patterns after a co-worker in his 50s was diagnosed with ALS. It seemed eerie since it was hardly the first time an Ames colleague was stricken with the disease, he said.

"I noticed this pattern of people getting sick, and no one seemed to be writing down these things," Spremo said. "Is there a problem here? I still don't know if there is, but it didn't look right."

Despite no formal training in medical research, Spremo began working in his spare time to map out where employees who contracted various diseases had worked by using old phone books, newspaper obituaries and word-of-mouth among the workforce.

His survey tracked about 170 people who had contracted either cancer, lupus, Parkinson's disease, and ALS (amyotrophic lateral sclerosis). Most of those diseases were scattered across the campus, but the ALS cases were unique because they were conspicuously packed in a tight section of older buildings dating back to the 1940s.

Spremo shared his research with officials from the union, and the information was eventually disseminated among Ames administrators, health regulators and even the offices of U.S. reps Jackie Speier and Anna Eshoo. The disease map drove many employees to demand more information, said Tom Clausen, vice president of the Ames Federal Employees Union.

"Most people who see this map get concerned," Clausen said, "We have a lot of people who love working at NASA, who love making a significant contribution through the work we do, but they need to know they're working in a safe place."

Clausen declined to share the disease map with the Voice after discussing the request with other union officials.

NASA employees' fears over possible toxic hazards have been heightened over recent years. One flash point for those concerns came when a season of heavy rainfall caused flooding in the basement of the aging Building 241. The basement, formerly used as a print shop and mail room, was reportedly built on a flawed foundation designed with metal sections lodged in between concrete slabs. Decades of corrosion had caused the metal portions to wear away, leaving space for groundwater to begin leaking inside.

At the time, Building 241 was situated about 100 feet outside the boundary for where the toxic groundwater plume was located, meaning the EPA was not testing it for contaminants. NASA eventually closed off the basement of Building 241, yet employees working on the upper levels were concerned that TCE vapors could still be wafting up through the ventilation system, Clausen said. Trichloroethylene, more commonly known as TCE, is considered carcinogenic to humans by all routes of exposure, according to the EPA.

More recently, a 2013 U.S. Department of Defense report found toxic vapor levels exceeding EPA limits inside several occupied buildings at Moffett Federal Airfield, including the NASA Ames convention center and the flight systems research lab. Around the same time, parents who worked at Moffett Field voiced concerns that a children's day care center located off R.T. Jones Road could be exposed to soil contaminants from a nearby U.S. Army construction project that was digging up dirt along the contaminated Superfund plume.

Employees' concerns that harmful vapors could somehow be permeating into their workspaces are often tied to the age of the Ames facilities. The site reportedly has a $500 million backlog of deferred maintenance projects, much of it for old infrastructure that dates back to World War II.

Clausen explained that NASA employees paid close attention in 2013 as Google workers went public with complaints about similar toxic vapors discovered in a cluster of relatively new Whisman neighborhood offices. For many NASA workers fresh out of college, it was the first time they had learned about the Superfund pollution that stretched across the area, he said.

"When employees here at Ames heard about what's happening at Google a mile away, they're curious: 'Is the air in my workspace safe too?'" Clausen said. "It's one thing to go into a dangerous place for a few minutes; it's another to be working in a low concentration for years."

Some employees developed their own ways of coping with the potential hazards. One office worker mounted carbon filters everywhere in her office to leach any volatile chemicals out of the air. Bottled water is generally favored in lieu of tap water.

In an interview with the Voice, one longtime Ames researcher described how a first-floor lab in Building 240 where she routinely worked would immediately give her a sore throat and a sharp migraine. The feeling was like "night and day" when she entered the room, and other employees described similar symptoms, she said. The Voice agreed to withhold her name over concern for her job security.

As a scientist, she said she realizes the data doesn't support the toxic plume being the source, but it's something she finds hard to dismiss. She is content now that she works on the other side of the campus, but if she was relocated back to that building, she said she would probably quit.

"Something is wrong there," she said. "I don't know if the groundwater plume is it, but it fits the profile."

Based on the mounting concerns, NASA administrators on Oct. 19 held a first-ever town hall meeting to address issues surrounding the Superfund site. The room was packed with a standing-room only crowd of about 120 people. A panel of officials from NASA, EPA and OSHA gave assurances that employees' health and safety was a paramount priority.

OSHA Industrial Hygienist Amber Rose said her agency received an anonymous complaint in November 2015 alleging that workers in Building 241 were getting sick from groundwater vapors as well as mold and algae. Her agency partnered with EPA officials to install a series of air-sampling canisters around the building. While a few chemicals in the air were detected, they were well below hazard levels and were considered "insignificant," Rose said.

A few months later, a second complaint to OSHA was made, warning that employees in buildings 241 and 240 were suffering from chemical vapors, particularly in the early morning. Rose said she returned to the Ames campus in July to install a set of charcoal tubes designed to test for five different hazardous chemicals.

"All of my results came back with nothing detected," she told the audience. "At this time, we haven't uncovered any hazard to make us believe there's any issues related to the groundwater."

The OSHA inspection team did issue a hazard alert letter to NASA regarding black gunk that would sometimes fall from the air ducts in older buildings, according to employees. A mass-spectrometer analysis showed the substance was some kind of acetate, but Rose said it wasn't likely to be harmful unless employees were exposed to a large amounts.

Rose admitted the failure to detect any prominent chemicals probably did little to mollify any NASA employees fretting about subtle environmental hazards. In partnership with the Ames employees' union, she recently requested that a division of the U.S. Centers for Disease Control and Prevention conduct an epidemiological study that would look into the ALS patterns uncovered by Spremo. The CDC division ultimately declined the request.

In an email to the Voice, a CDC spokesman said that an epidemiological study would be difficult due to the challenges of verifying diagnoses, potential environmental factors and the background history of ALS cases. The CDC's ALS registry has only been active since 2010 and it has not conducted any previous studies on clustered ALS cases.

OSHA and union officials say they intend to continue seeking a medical professional or perhaps a graduate student to pursue a disease study at Ames.

NASA administrators at the meeting emphasized they were committed to safety and they urged employees to immediately bring any concerns to their attention.

"Ames clearly is committed to maintaining the health and well-being of its employees and partners," Ames director Eugene Tu said in a statement to the Voice. "NASA will continue to monitor conditions and will continue to conduct sampling and studies. Ames will share results with employees, the employee union, tenants and with the relevant agencies."

there was a cluster of ALS patients in the football 49er team in around 1980. My father died of ALS at this time also. There was a suspicion that the turf was fertilized with Milorganite a product from Milwaukee sewage. My Dad was using it on his lawn. No one ever really proved the relationship, but I think the product was pulled from use at the old Kezaar.Stadium,

I find this disturbing. Thank you for the article. I worked in these NASA buildings.
I'm torn between the fact that you pretty much can't swing a dead cat in California without hitting a Superfund site (so,mwhats the big deal?), and the reality that we all live here and cancer, autoimmune disease, chronic illness and allergies have skyrocketed in the last 30 years.

I see Google has come in to the EXACT location where those big corporations were busted in the 1980s for dumping toxic waste. It wasn't just this location, it was all over Santa Clara County. As a teen, I'd be at afterschool sports and it seemed like every day another coma you, where someone's father worked, was in the news and busted for chemical waste.

I've seen a few posts by people who appreciate Google's prescience, but they apparently don't remember what caused the depression here back then was all those companies when they abandoned their buildings, leaving them empty for a decade. They were empty until the real estate prices rise high enough that they outweighed the cleanup costs. The old GE and Fairchild sites were bulldozed in Dec, 1996, and into 1997. The dirt was hauled away and replaced from what I saw. Businesses and expensive homes were built where these old buildings had been.

I see the monster businesses coming in to Mountain View and people don't get it. These companies come in, trash the environment in the name of progress and then leave when they've made it so toxic that they're no longer allowed to occupy their own buildings. We, the residents of Mountain View, are left holding the bag, the economic downturn, the toxic waste, the lack of oxygen because open space and plants have been destroyed for more buildings in the name if housing or industry.

I don't blame NASA. I worked there and it was a wonderful experience. NASA is one of the few sources of real scientific research. I blame the greedy industries, obsessed with marketing campaigns and selling junk that no one needs, wants or can afford. We don't need them here.

The three companies responsible for the original Middlefield-Ellis-Whisman Superfund site remediation were Intel, Fairchild, and Raytheon.

The amount and distribution of TCE under Moffett is not at all entirely due to the plume from the M-E-W sources. The Navy used to wash airplanes with TCE, and the M-E-W plume has merged with the large Moffett plume.

My brother worked in the Fairchild " Rust Bucket " as it was called then. Even the " bunny suits " did not keep people safe during the fabrication of semiconductor wafers. We worked with " two step " gases. That meant you can take two steps before you died from exposure to them. Arsine, silane and several other very toxic gasses are used in semiconductor wafer fabrication. We even had full kits of SCUBA gear to drag the bodies of exposed people from the fab areas.
I am not surprised at the toxic water plume has reached so far, I'm just glad it does not threaten our house in Mountain View near the 85 and Moffett intersection.

My father owned the Chevron station at the corner of Whismon and Middlefield. Both he and my grandmother (who worked there daily to do the accounting) died of Parkinson's. My brother, sister, and I worked there for years, and are in fear that we too will get one of these neurological diseases. Is there a group we can join to track this? I've heard along Whisman, there has been a huge Parkinson's cluster. From what I was told by the City of Mt. View, there is no "link" to the ground contamination and these diseases! I say NO!!!! Someone needs to do something about this!!!! We need help and restitution for the lives lost, and the many families who have suffered helping and watching their loved ones die of these horrible diseases!!!

These chemicals are not only affecting the NASA workers. We lived on base in Westcoat Village for 5 1/2 years. I did not work at the time of our arrival, I was a full time college student taking mostly online classes and was home pretty much all of the time. I knew several women including myself that were having all kinds of health problems. I did not know anything about how toxic it was in Mountain View, and on base. And by the time I found out it was too late. My health has been adversely affected when I had a serious fall when I lived there, and am now disabled because of it. I had become a total klutz and kept injuring myself and couldn't figure out why. And as time went on I started having all kinds of health problems. We ended up moving from a 2-story home to a single level handicap accessible house, and by the time we left I was bedridden 24/7. That second home was definitely more toxic than the first. While there I was laying in bed watching the ceiling around the heater vents turning black, thinking this place is killing me and I'm going to die here. I could feel my body shutting down. But when you try to talk to people, like doctors, about it they look at you like you are nuts. It was crazy, and I know that place was killing me. I went from being a perfectly health middle aged woman with only some neck/back pain to being disabled and unable to work. The EPA had a meeting in housing where they stated the housing office didn't have to warn us about the environment around us because we were only renters. They tested my house and it tested high for vapors, but the EPA said they were another kind and not TCE. I think it's shameful that the government thinks it's okay to put our military and their families in such a place, and without warning them of the possible effects on their health due to it being on a superfund site. They ruined my life, and no one even cares.

Just an update:

I asked the Council about the indeterminate problem with TCE, and Lenny Siegel criticised my question by saying he had up to date ambient TCE data. Alana Lee stated that 1 PPM is considered unsafe. Conversion means 1000 micrograms per litre.

From what I can see, the latest Vapor data results I can find on the EPA website was 2014. This information seems extremely out of date. So far I have not received any updates. Lenny Sigal claims to have up to date data, I look forward to receiving it.

Lenny Siegel tonight during the City Council Meeting break claimed to me that the NBC Investigates report I have been using as a reference was presenting false information. I was completely surprised he would say that. So I asked why didn't he seek a retraction or correction in the story? He didn't seem to indicate he ever tried. This behavior activated my suspicious reptilian brain. My intent is to contact Steven Stock who broadcast the following report (Web Link)

I await an email by Lenny Siegel to explain how the report could be misleading.

My first reaction to this comment was that if such a misleading story existed, how could the NBC Investigates broadcast this news story? They surely would do all efforts to fact proof the story so that no one could disqualify its validity. From what I see, Steven Stock has no history of making false statements or even accidentally broadcasting misleading stories. I am concerned we are being given another "fake news" excuse.
