Chromium 6 in U.S. Tap Water

Chromium 6

In their recently published study on hexavalent chromium (chromium 6), the Environmental Working Group (EWG) found that 31 of the 35 U.S. cities that they tested have “measurable levels of hexavalent chromium,” which indicates that “American tap water may be widely contaminated with this potent toxic substance.” Four of the 35 cities that tested positive for hexavalent chromium are located in California, including “Riverside (1.69 ppb), San Jose (1.34 ppb), Los Angeles (0.20 ppb) and Sacramento (0.16 ppb).”

Hexavalent chromium is a known carcinogenic chemical. It was made famous in the movie Erin Brockovich, starring Julia Roberts, that tells the true story of the cancer-stricken community in Hinkley, California that won a settlement from Pacific Gas and Electric Co. for contaminating their local tap water supply with hexavalent chromium.

Facts from the study:

  • At least 74 million Americans in 42 states drink chromium-polluted tap water, much of it likely in the cancer-causing hexavalent form.
  • The highest levels were in Norman, Okla.; Honolulu, Hawaii; and Riverside, Calif. In all, water samples from 25 cities contained the toxic metal at concentrations above the safe maximum recently proposed by California regulators.
  • The National Toxicology Program has found that hexavalent chromium in drinking water shows clear evidence of carcinogenic activity in laboratory animals, increasing the risk of otherwise rare gastrointestinal tumors (NTP 2007, 2008).
  • Levels of the carcinogen in 25 cities tested by EWG were higher than California’s proposed public health goal.
  • Studies in both animals and people show that exposure to hexavalent chromium via drinking water leads to elevated chromium levels in tissues, particularly the gastrointestinal tract, blood, liver, kidneys and spleen, and in increased toxicity (Kerger 1996; Finley 1997; Anderson 2002; NTP 2008; EPA 2010a).
  • Chronic exposure to hexavalent chromium in tap water is likely to raise everyone’s risk of cancer, but the young and the medically impaired may be especially vulnerable.
  • Hexavalent chromium (or chromium-6) gets into water supplies after being discharged from steel and pulp mills as well as metal-plating and leather-tanning facilities. It can also pollute water through erosion of soil and rock.

Let’s Do The Math

By replacing over 800 plastic water bottles, each Revolve Tap Water Filter protects your wallet, your health, and the environment.

Let’s do some math to prove it.

For those of you who are not mathematically inclined, do not worry we have done all the calculations for you. And for those crazy people who do like math, feel free to check the answers.

Savings to your Wallet
• 1 Revolve Tap Water Filter replaces (over) 800 single use plastic water bottles.
• Average cost of 1 16oz bottled water = $1.50
• 800 X  $1.50  =  $1,200 saved

And that’s just for one person!

Savings to the Environment
1 Revolve Tap Water Filter saves 25 gallons of oil, 200 pounds of CO2, and 300 gallons of water. Plus 800 plastic bottles from landfills.

Here’s how:
• Avg. amount of oil involved in production of 1 gallon of bottled water = 0.25 gallons
• Avg. amount of C02 involved in production of 1 gallon of bottled water = 2 pounds
• Avg. amount of waste water involved in production of 1 gallon of bottled water = 3 gallons

Since the Revolve Tap Water Filter replaces over 100 gallons of bottled water, multiply all these numbers by 100, and look at how much waste you’ve saved. And that’s just by using one Revolve Tap Water Filter!

Savings to your Health
Scientists have found that plastic bottled water has more bacteria than tap water. In fact, 70% of the most popular bottled brands have bacteria, with some reaching levels 100X above those of the permitted level. More information on these findings is provided by the Telegraph:

http://www.telegraph.co.uk/health/healthnews/7763038/Bottled-water-contains-more-bacteria-than-tap-water.html

And what about the bottled water that is simply tap water repackaged? The out-of-date regulations on tap water pose some serious health risks. Only 91 contaminants are regulated yet over 60,000 are present within the US. More information on these findings provided by the New York Times:

http://www.nytimes.com/2009/12/17/us/17water.html

Bacteria + all sorts of unregulated chemicals = serious health issues. Revolve Water filtration = one serious solution!

And that’s one healthier life.

Q&A with Jenny Kalmbach and Morgan Hoesterey fron Destination 3°

Jenny Kalmbach & Morgan Hoesterey

Destination 3° is a unique film about two of the world’s elite female standup paddleboarders, Jenny Kalmbach and Morgan Hoesterey, who recently traversed the three degrees of latitude that separate the Hawaiian Island chain. Inspired by the opportunity of adventure they engaged both mental and physical adversity, and also discovered the devastating effects of pollution along these legendary waterways.

We’ve had the chance to catch up with Jenny and Morgan to ask them a few questions.

What was it like crossing these channels with so much open-ocean in front of you?
It was definitely a bit daunting at the start. We knew how much work had gone into making the adventure happen and were concerned about not being able to complete our goals. That first channel, from Big Island to Maui, is one of the most dangerous in the world and we had been delayed due to extremely bad weather. Our fear was that we wouldn’t make it across the first channel and our journey would start off wrong. Fortunately, that never happened and we made it successfully across that and each channel until we reached Niihau. There are times in each channel when you find yourself in the midway point and look back and realize that you’re just as far away from that island as you are to getting closer to the next island. It suddenly makes you feel so small but at the same time, it can be exhilarating. The most interesting moment was setting out from Oahu to Kauai. Kauai is 82 nautical miles from Oahu and when we started out we couldn’t see the island at all. Looking out over the horizon and seeing nothing but water was a surreal feeling. I remember thinking to myself how strange it was to not be able to see our final destination. We had to trust that the GPS on our boats were leading us in the right direction…and luckily, they were.

Where was it that you first encountered the effects of pollution on your journey?
We saw signs of the plastic contamination throughout our journey but it was on the island of Lanai that it became obvious how big of an issue it is. We were visiting Shipwreck beach on the North side of the island and the entire beach was covered in bits and pieces of plastic… plastic bottles, caps, remnants of balloons, glue sticks, fishing line… it was really sad to see.

We understand that you are raising funds for the Algalita Marine Research Foundation. Who are they & what do they do?
Algalita Marine Research Foundation is non-profit organization whose sole mission is to protect the marine environment. It is the leading research organization studying the prevalence and quantification of plastic debris in the North Pacific Sub-tropical Gyre, and the biological impact of plastics on marine life and the human food chain. The global plastics issue starts on land. Approximately 80% of all debris that winds up in our oceans comes from land-based origins, with only about 20% attributed to sea-related activities. The properties of plastic do not allow for absolute bio-degradation within a human lifetime or even several generations of human life, nor can it dissolve into organic matter that can re-enter the life cycle.

To find out how you can help reduce your own “plastic footprint,” go to www.algalita.org.

What would you most like people to take-away with them after seeing your film?
The most important thing is to first realize that plastic contamination in our oceans is a major problem and it’s not going to simply disappear. We need to all work together to come up with a solution but in the mean time there are things that we can do to lessen the impact. Reducing or stopping the use of plastics bags and plastic bottles is a great start. When you’re heading out of the house, take your reusable bags and make sure to have a reusable water bottle, like the Revolve Tap Water Filtration Bottle!

How can people get the opportunity to see your film?
We are currently showing our film at various film festivals around the US. We have an upcoming screening at the Santa Barbara International Film Festival. Our film will also be available for purchase in March 2011. For more information check out our Destination 3 Degree facebook page.

Colleges Ban Bottled Water

Many colleges and universities have joined the green movement. New offices of sustainability, new majors and minors in renewable energy, sustainability studies, and environmental studies, and new clubs focused on green initiatives have sprung up across campuses nationwide. In fact, some students may be looking at specific places of study because of their very commitment to going green.
One group of colleges and universities stands apart in their commitment: those that have decided to ban plastic water bottles. New York Times describes the addition of Seattle University and the University of Wisconsin, Stevens Point to the list of campuses that have banned plastic bottled water.

With Washington University in St. Louis leading the movement in 2009, the following colleges and universities in the US and Canada have now banned the sale of bottled water, according to the Association for the Advancement of Sustainability in Higher Education:

  • Belmont University
  • Oberlin College
  • Seattle University
  • University Ottawa
  • University Portland
  • University of Wisconsin, Stevens Point
  • Upstate Medical University
  • Washington University in St. Louis

Other universities have banned plastic bottled water from their dining halls, including Gonzaga University, New York University, Stanford University, Stony Brook University, and University of Maryland (Association for the Advancement of Sustainability in Higher Education). While bans may not yet be officiated at other institutions, there are student campaigns to ban bottled water at universities and colleges like Brown University, Cornell University, Evergreen State College, Pennsylvania State University, and Vancouver Island University.

These students, colleges, and universities have taken a great leap forward in bringing back the tap. Highlighting stats like 86% of plastic water bottles end up in landfills and demonstrating that bottled water bans can be effective, these institutions call us to act in our own communities. Let’s stop wasting plastic, money, and resources, and start following their lead.
