Artificial Turf. Credit: Anthony V. ThompsonIt's easy to get scared. You look around the Oakland office of the Center for Environmental Health, and lead is everywhere. Piles of toys that are loaded with lead. Lunch boxes and kids' backpacks that have tested positive for high levels of lead. Samples of artificial turf.

And that's just the beginning. Lead has been found in venetian blinds, in pens, in the glaze of ceramic cups and bowls. It has been found in imported candies. And one Mexican folk remedy to cure stomachaches has landed a number of children in the hospital recently – a packet of powder that is almost entirely lead.

Since the effects of lead are cumulative, all those points of contamination add up.

Children's developing brains and central nervous systems are most susceptible to damage from ingesting lead. That's why a new federal standard for lead in children's products was recently put in place. And that's why the Center for Environmental Health, for one, focuses on products that come in contact with children on a daily basis.

The amount of lead in artificial turf, by itself, is unlikely to cause lead poisoning. And the same is true for the amount of lead found in lunch boxes, or in children's jewelry. But medical experts say that if kids play on artificial turf in the morning, distractedly put a charm bracelet in their mouths during class, and eat food from a lunch box with lead embedded in the vinyl – then those kids are at risk for lead impairment, such as a loss of IQ points, a sign of brain damage.

Areas where the oil spread after the spill. See this map and others.
November is the month when thousands of migratory birds on the Pacific Flyway make their stop in the San Francisco Bay Area. It's also the month when herring arrive in the Bay in gigantic schools – tons and tons of the tiny fish. It's the month when salmon make their way into the bay, on their way to spawn upriver.

And November's the month last year when the Cosco Busan crashed, leaking 53,000 gallons of black goo into San Francisco Bay.

So biologists will be particularly attentive this November, one year after the oil spill, to see if there's a noticeable dip in the numbers of herring in the Bay, or the number of migratory birds that alight here.

The number of birds harmed by the oil spill is not really known. More than 2,000 birds were killed – but those are simply the birds that were identified, not the total number. Since many dead birds in remote areas were never found, and since predators took away many of the hurt birds, the estimate for the total number of birds harmed by the spill is many times higher than that. So researchers are conducting experiments to determine a provable, scientific estimate of the number of birds killed or harmed by the oil spill.

According to California Fish and Game scientist Julie Yamomoto, it only takes a spot of oil the size of a nickel to harm a bird. It's not just uncomfortable, she says, it's actually lethal – because the oil is like a hole in a wetsuit, and birds that have been oiled become hypothermic. And they also lose buoyancy, so birds can actually sink and drown in the ocean.

All the experiments and data on habitats, fish, birds and other wildlife will be compiled into something called the Natural Resource Damage Assessment.

It's nicknamed NRDA (pronounced "nerd-a") and that's pretty apt. It's a little wonky, to say the least. The data is supposed to be completed by the end of next year, and then the NRDA report is expected to be compiled and submitted sometime in 2010.

UPDATE on 10/23/09: From the San Francisco Chronicle – "Two World War II cargo ships moored among Benicia's fabled "ghost fleet" since the late 1940s will be towed out of Suisun Bay next month, scrubbed clean in dry dock and ultimately sent to Texas to be broken up and sold for scrap".

Read more about the clean-up effort in the Chronicle here.

On the surface of the story, the Ghost Fleet of Suisun Bay (commonly called the "Mothball Fleet" but most accurately referred to as the Suisun Bay National Defense Reserve Fleet) is leaking toxic waste in the form of peeling ship paint containing nasty heavy metals into an already stressed bay ecosystem. Bad guys: Mothball Fleet. Good guys: Enviros who are suing. Simple, right?

But when we began digging into the story, we found the origins of the problem and current impasse to be a bit more convoluted. I'll attempt to quickly summarize: The fleet has been there since the 1940's. It wasn't until 2006 that it came to light that the exterior paint is peeling from the ships and falling into the bay. Many tons of toxic heavy metals have already fallen into Suisun Bay and there's a lot more to be had. Oddly enough, the story was initially triggered by a study that was commissioned by the federal body who oversees the fleet, the Department of Transportation's Maritime Administration, or MARAD for short. So the Contra Costa Times got a hold of a draft of that report and now, the ships are at the center of a different kind of battle long after they've been decommissioned.

Environmental groups (NRDC, Arc Ecology and San Francisco Bay Keeper), community leaders and water regulators justifiably want MARAD to either remove or better maintain the ships so that they are not polluting these waters that serve as both fishing and nursery grounds for several fragile or threatened species. That includes humans who are often out there catching fish for dinner. Historically, MARAD has been regularly removing and dismantling the ships but like most federal bodies whose charter was drafted during WWII, alacrity is not at the top of their mission statement.

The real issue now seems to be that MARAD has had to completely stop removing ships because they can't clean their hulls of potentially hazardous invasive biological species (to comply with the U.S. Coast Guard's National Aquatic Invasive Species Act of 2003) without scraping more paint into the bay. So, until someone develops a system to clean the hulls that doesn't scrape more paint into the water, the San Francisco Regional Water Quality Control Board says that MARAD can't remove the ships.

The one possible solution that everyone pretty much agrees upon is to dismantle the ships locally so that they don’t have to be cleaned of invasive species. There are currently no ship dismantlers operating on the West Coast but there's a company called Allied Defense Recycling located on Vallejo's Mare Island Naval Shipyard that's chomping at the bit to tear those ships apart. But they've also run into red tape. And while they await permits and approvals from multiple parties, the ships continue to rot and pollute.

It's always easier to write a story with clear heroes and villains. But to me, it does seem that MARAD, environmental groups and water regulators all agree that we have a problem that must be addressed. So, what now? I guess we wait. Perhaps this lawsuit will kick start some aspect of the clean-up process but in the meantime, frustration mounts for all parties involved and many pointing index fingers are suffering from overuse.
