Alderman Wants Brockovich at Water Testing

Well, I'll be. Alderman Ed Burke has invited renowned environmental lawyer, Erin Brockovich, to the soon-to-be-held public hearings on the level of hexavalent chromium recently discovered in the city's water supply from Lake Michigan. This is the same pollutant found in the now groundbreaking case of the residents of Hinkley, California, vs. the Pacific Gas and Energy company, a case that Brockovich researched, launched, and championed all the way up to the highest courts, which ended in a $330 million victory for the plaintiffs and fame and good fortune for Brockovich. What's more, according to Burke, Brockovich's people say she is "available". So an environmental rock star may be coming to Chicago! I am beyond excited about this.

The level of chromium-6 found in Chicago's water supply last month was 0.18 parts per billion, which is now nine times higher than the acceptable 0.02 ppb adopted by California officials just this month. Although nothing has been said about limiting the amount of Cr-6 in our local water supply, officials vow to begin quarterly testing for the substance, and to report their findings online. The EPA has also agreed to review it's current chromium limits, and to consider separating the villified chromium-6 from its cousin chromium-3, which is an essential nutrient.

While chromium levels can knowingly be reduced through fancy water filtration systems, carbon filters (like the one in my fridge) have not yet been proven to separate this chemical out of the tap water (yikes!)

Revelations?

Is the sudden flurry of recent news reports on the "aflockalypse" keeping anyone else awake at night? My eco-insomnia started on New Year's Day with a chilling story of 5,000 blackbirds falling from the Arkansas sky, and it seems like every time I turn on my TV nowadays, there's another report of mysterious mass wildlife deaths. We're barely a week into this new year, and already we've got reports of species turning up dead in Kentucky and Arkansas and Sweden, in numbers of Biblical proportions. And it's not just birds; dead fish have washed up on the shores of the Chesapeake Bay, dead crabs were found littering a beach in Britain... what (or who!) is next?

So what's going on here? Is our civilization being punished once more with a series of plagues? Did the Mayans correctly predict the coming of the end of days? Or is there something to the many conspiracy theories floating around, warning of covert government operations and chemical/biological warfare testing and the like?

Even though I'm exhausted, my judgement isn't clouded enough to buy into any of these crazy conspiracy theories, and I suspect that the day after the Mayans say the Earth will end will be remarkably similar to January 1st, 2000 (judgement day for Y2K); surprisingly uneventful despite all the hype. Nor do I entirely believe the reports that are telling us not to worry because scientists have decided that the blackbirds in Arkansas were literally scared to death by New Year's Eve fireworks the night before. I am worried, and I don't think the real answer is as simple as the (sometimes conflicting) news reports would lead us to believe!

I resolved not to spend another sleepless night speculating about the disturbing events of recent days, but to instead try and find a more logical explanation. So I turned on the Internet, set my common sense filter to "high", and started searching reputable biological and environmental sites. And here is what I found: sudden mass wildlife deaths are nothing new, nor are they uncommon. The U.S. Geological survey actually keeps a running tally of all reported die-offs here. In fact, scientists believe the species-specific deaths are more common than even this chart shows (as they think most die-offs go unreported) and that the media coverage (not the deaths themselves) is the only thing that has changed in recent days.

In reading through this chart, I see that most of the species on this list are birds, but that the suspected causes of death vary. While trauma is listed quite frequently, so are a number of various diseases. And I know (even from my limited training in biology and ecology) that toxins/pollutants and loss of habitat are other contributing factors. That in itself should give us plenty to worry about; I read somewhere else that as many as one in six species of birds are in danger of becoming extinct!

What's more, animals often succumb to disease, pollution, and other environmental factors long before humans. Some scientists suspect that these dead animals are the "canaries" in our proverbial coal mine, and it's high time we stop and listen. Just as animals can predict and detect severe weather and instinctively know when to take cover, many human diseases start in wildlife populations (bird flu, swine flu... these aren't just cute names!). If we want to stop their problems from becoming our problems down the road, we need to work to protect the environment we all share; humans are not immune!

The beauty of biodiversity is that every creature plays a vital role. We may not know what purpose each species serves in relation to our own existence, but we don't want to find out after they're gone... Sweet dreams!

Hexavalent Chromium Found in Cities' Water Supply

Remember the based-on-real-life movie, "Erin Brockovich", starring Julia Roberts as a feisty, lingerie-flaunting, single mother? Yes? Well, you may also remember that Robert's unemployed character was so desperate for a job that she took an entry-level position at her lawyer's firm, which was seemingly offered to her out of pity. And I'm sure everyone remembers that Brockovich stumbled upon a covered-up accusation of water pollution by corporate behemoth Pacific Gas and Electric, and took it upon herself to conduct follow-up research and rally more than 600 residents of the town affected to become plaintiffs of what turned out to be a huge class-action lawsuit (which, by the way, they won) against PG & E. This true rags-to-riches story ends with Brockovich going to law school and becoming one of the nation's most prolific environmental lawyers.

What you may not remember, however, is the contaminate at the center of this legal battle. The alleged cancer-causing metal in question was hexavalent chromium, or chromium-6. The good news is that the NIH finally labeled chromium-6 as a "probable carcinogen" (it's believed to cause stomach cancer, among other ailments) back in 2008, and that the great state of California (which has led the way in setting environmental standards and regulations since the 1970s) proposed to set a MCL (a limit on the acceptable amount of contaminate present) in its drinking water to 0.06 parts per billion. The bad news is that the EPA has no limit on the allowable amount of Cr-6, nor does it regularly test the nation's water supply for the presence of such a chemical.

So why do I think this is a big deal? Well, an independent environmental organization, the Environmental Working Group, took it upon themselves to test the drinking water of 35 cities around the U.S.; chromium-6 was found in the water supply of 31 of those cities, and in 25 of those cities, the amount was well above California's proposed limit.

In Chicago, the tests revealed Cr-6 amounts of 0.18 parts per billion; three times what California suggests is safe. Uh oh. The water pollution in this city is suspected to have come in part from the south side steel mills and other riverside industries, as the substance was widely used until the mid 1990s. Although the EPA has agreed to review its stance on hexavalent chromium, utility companies and industrial polluters are already fighting back. If the EPA does in fact set limits on the allowable amount of chromium-6 to enter the water supply, it will be very difficult (not to mention expensive!) to clean up, and companies are reluctant to dip into their profit shares to remediate the problem in the interest of public health. We're all drinking the water, though, so if I knew there was a way to lower my family's risk of certain cancers, liver and kidney damage, and leukemia, I'd consider it a small price to pay.

Meigs Field Now Bird Sanctuary

Northerly Island is, by all accounts, an enviable piece of real estate. Located just southeast of the Museum Campus, the peninsula was once home to a little airport known as Meigs Field, which met its now-infamous end back in 2003, when Mayor Richard M. Daley covertly sent a fleet of bulldozers to tear up the runways in the middle of the night, without warning the public or getting approval from any of the city's usual legal channels. Unapologetic in his actions, Daley cited only a concern that having an airfield so close to downtown posed a "terrorist threat", in a very-belated response to the September 11th attacks.

Although pilots and other aviator enthusiasts still harbor a great deal of resentment toward the mayor and his seemingly rash decision, it sounds like Northerly Island will soon become a permanent hub for winged creatures of the feathered variety.

In the years since the runway debacle, the Park District has already made great strides in beautifying Northerly Island. They have done a good deal of prairie restoration on the southern half of the peninsula, and erected the Charter One Pavilion, a 7,500-seat (temporary) concert venue to the north. This article in yesterday's Tribune details how architects plan to unveil green designs for a permanent concert facility (revenue from these concerts will help fund this project) and to restructure the old terminal building, by removing the walls (which have claimed the lives of many a migrating bird) and turning it into an open-air pavilion.

A more concerted effort will be made to turn the island, which is on the direct flight path of many migrating birds, into a bird sanctuary and hospital, while underwater rock formations will harbor many more species of aquatic plants and animals. I walked the length of Northerly Island earlier this fall, and despite a group of tourists on Segways, I found it to be a surprisingly peaceful place. I think a nature sanctuary is a great idea, and the views can't be beat!

What's in YOUR Water?

Just as many people find it hard to remember life before cell phones, others can barely remember life before bottled water. Do you remember when bottled water was "invented"? I do. We must have all been so primitive and uncultured before then... to think that we all used to drink (*gasp!*) tap water... the horror!

Oh, wait. I still drink tap water, and I think all of you should, too. Now, I'm not normally one to blatantly impose my views on others; as long as your actions aren't affecting me and you're not hurting yourself or anyone else, I'm willing to put up with a myriad of different things. But in this case, I think the actions of bottled water drinkers are hurting themselves and others, and here's why.

We've all heard the alarming statistics of the number of plastic beverage containers that wind up in landfills: they make up 45%-60% of all litter in this country, and the number of bottles discarded last year alone, when stacked end to end, would be enough to reach to the moon and back six times, or something crazy like that. Discarded plastic bottles are also clogging up our oceans, comprising a hefty percentage of the giant patches of garbage floating in our polluted seas; the 21st century version of the plastic six-pack rings people got so fired up about back in the '80s.

I know what you're thinking: "Of course litter is bad. I recycle my plastic bottles. What else have you got?"

If pollution doesn't weigh as heavily on your eco-conscious as it does mine, then consider this. Our government, in its infinite wisdom, passed a great deal of environmental legislation back in the 1970s and 80s, and as a result of pieces of legislation such as the Clean Water Act and the Safe Drinking Water Act, all municipalities have to meet very specific criteria when it comes to the treatment of drinking water. This includes regular, daily testing of the water that comes out of our tap. And no, it's not 100% pure, but some minerals are good for us and we can rest assured that it has been tested for a myriad of toxins, and test results came in below the MCLs for each of those toxins. We can use additional in-home filtration systems as an extra safeguard or if we object to the taste, but know that in the 21st century, the water that comes out of the tap in this country has been thoroughly tested and is safe to drink.

Still not convinced? Then consider this: bottled water came onto the scene several years after the afore-mentioned bills were passed, so our government, in its infinite wisdom, delegated the regulation of bottled water to the FDA instead. The FDA is so huge that it can't really test every product under its jurisdiction to the extent that is sometimes needed, and often approves items (such as water) that are "generally recognized as safe" (GRAS) without closer inspection. The FDA does not investigate advertising claims of "mountain-pure spring water" and the like, and only gets around to testing bottled water every three to six months... if we're lucky.

Independent testing has since revealed that many of these claims are false, and that most bottled water is just packaged tap water. It's rarely cleaner than what comes out of our faucet, and in some cases the level of contamination is worse. If, for example, bottled water is contaminated during the packaging process, it could take months to detect the toxin, and by that time, thousands of people could have already consumed the tainted water. Tap water contamination is detected and remediated much more swiftly than that.

My final argument against bottled water is this: bottled water came about because giant corporations such as Nestle and Coca Cola and the like found a sneaky new way to increase their sales. They've profited so much from designing clever advertising campaigns and making unfounded health claims about the benefits of their bottled water product, they've monopolized and have all but depleted once-public water sources in areas (such as northern Michigan) just to make a buck. Bottled water is the first step in turning a natural resource into a commodity, and that's a slippery slope to venture down.

Water is vital to our very existence, and the thought of allowing large companies to seize our water supplies and claim ownership of this crucial element is terrifying, indeed. So the next time you reach for an Ice Mountain or a Dasani, I challenge you to stop and think about what you're actually drinking!

Climate Change Exhibit

I practically skipped down to the Museum Campus last week to take advantage of one of the Field Museum's free days, which means reduced-price admission to their normally pricey special exhibits! I've been meaning to go see the Climate Change exhibit (as well as the robotic dinosaurs, which were very cool) all summer, as I'd heard so many good things about it that I wanted to see it for myself.

In my excitement, I arrived at the museum shortly after it opened, and had the entire Climate Change exhibit practically to myself. So I took my time meandering through the aisles, crammed floor to ceiling with historic facts, photos, meteorological diagrams, and flow charts, reading both the interest-piquing tidbits and the heavier scientific evidence behind the findings presented.

Of all the information presented, my only beef with the presentation was with the giant stuffed polar bear picking its way over a mound of garbage. I found the display to be apocalyptic and over the top; the present facts are scary enough, there's no need to make wild predictions about the future.

Although the subject matter was still alarming, it was not alarmist by any means, and I was pleased as punch to see no partisan politics in play whatsoever (which, in my opinion, is exactly as it should be!). The exhibit did exactly what exhibits do best, and that is to present the facts in a clear and concise manner. It's funny, but without partisan rhetoric and cliche talking points, skeptics have a much harder time arguing with the facts!

And the fact is that our planet is getting warmer. The all-encompassing takeaway I left with is that, while the rising temps may be due in part to the natural cycle of the Earth (take heart, skeptics!), our habits and actions as a society certainly aren't helping matters and may in fact be making things worse (hug a tree, hippies!). The exhibit left visitors with a sense of hope, detailing how a few small actions by many could change the trajectory of our future, because the health of the environment and the health of all species (humans are not immune!) are inexorably linked.
