Iowa Flood Waters Contaminated

I am still waiting to hear back from a spokeswoman at the USDA to find out the answer to the question I posed last week: who is in charge of protecting us from crops affected by flood water? In the meantime, I got an alert from the Centers for Disease Control about contaminated water in Iowa.  I can tell you, dear reader, that while you may not want to eat food grown along flooded riverbeds, you most definitely do not want to walk in that water, particularly if you have open sores or cuts on your feet and legs.  Exposing a sore on your skin to contaminated water puts you at risk for a nasty infection.

Is The Colorado River Becoming Radioactive from Upstream Uranium Mines?

It All Depends On Who You Ask

Las Vegas Water Offical Warns Radioactive Levels Rising

Sunday’s news was a bit disconcerting, when I read a small story at Tri-State Online.  Pat Mulroy, head of the Southern Nevada Water Authority was quoted as saying measurable quantities of uranium are showing up in Colorado River water, something difficult and expensive to remove before passing it on to consumers in Las Vegas.

She blames upstream uranium mining, especially in the Moab, Utah area, so I decided to take a look and see what’s happening up there.

To the best of my knowledge, there are no operating uranium mines in or near Moab, UT, or anywhere in the state of Utah.  So, I felt Ms. Mulroy was referring to the uranium mill tailings just outside Moab, where they’ve been for decades after the failure of the Atlas Minerals Corporation mill.

Contaminants in Flood Waters Threaten Food Part I: Who is Watching?

Farming near a river bed is a great idea until it floods.  Soil near riverbeds tends to be more fertile, producing more abundant crops.  But when the river beds flood and drench contiguous farm land, the water can drag unwanted contaminants to the farmland, exposing health risks to anyone eating the crops from the flooded land.  What kinds of contaminants?  Anything in the flooded water: machine oil, sewage, garbage, medical waste, manure.

Warren Buffett Ignores Klamath Dam Protesters Again

Un-Dam the Klamath

The four dams on the Klamath River in far Northern California are under relicensing, something that only occurs every 50 years. The dams are owned by billionaire Warren Buffett, who purchased Pacificorp, one of the lowest-cost electricity producers in the United States, three years ago. Many Californians were hopeful this purchase would mean the end to the dams, but their concerns for the salmon fell on deaf ears. Once again, Warren Buffett rebuffed salmon advocates.

On Saturday, May 3, 2008, American Indian tribes and salmon fisherman failed to gain a private audience with Buffett and were ignored at the Berkshire Hathaway Inc. meeting in Omaha, Nebraska. Protesters shouted, “Un-dam the Klamath! Bring the salmon home!“, while shareholders enjoyed complimentary cocktails Friday night. For two years, an unprecedented alliance of tribes, businesses, conservation groups and commercial/recreational fishermen has tried to reach an agreement with Buffett for dam removal. Buffett said that his company would not decide the fate of the Klamath dams, but Berkshire will defer to regulators in California and Oregon. Ironically, dam removal is cheaper than building the fish ladders regulators are recommending. Read the rest of this entry »

Taking Water for Granted? Think Twice

Pouring drinking water into a glass. (Photo courtesy of Walter J. Pilsakvia Wikimedia Commons.)Water is essential for life, but humans are placing a growing burden on this natural resource … risking our own future well-being. More and more news comes out every day about the dangerous game we’re playing with our water supplies, and a growing number of people are warning water could become just as volatile an issue as oil in years to come.

Consider some of these water facts, and the implications they have for humanity:

Just this week, Sandia National Laboratories warned more than half the countries in the world could face “freshwater stress or shortages” by 2025. By 2050, that percentage could rise to 75 percent.

Drugs In My Bottled Water Too

faucet2.jpg

The recent revelation by The Associated Press that our tap water contains traces of pharmaceutical drugs, hormones and disinfectants elicited a bit of “I told you so!” from The Environmental Working Group when I spoke to them this morning.

Way back in 2005 they published a report, The National Assessment of Tap Water that found that:

Tap water in 42 states is contaminated with more than 140 unregulated chemicals that lack safety standards. In an analysis of more than 22 million tap water quality tests, EWG found that water suppliers across the U.S. detected 260 contaminants in water served to the public. One hundred forty-one (141) of these detected chemicals — more than half — are unregulated.

They posted an update on their report today with this comment from Jane Houlihan, EWG Vice President for Research

“Once again, the press is doing EPA‘s work when it comes to informing the public about contaminated tap water.“

Uh yay.

Tidal Energy: the Race is On

Nova Scotia

A tidal energy facility in Nova Scotia could help fuel development of this emerging renewable energy source.

The last few years have been a time of amazing growth in the renewable energy industry and the renewable energy potential of many regions is increasingly being utilized. Tidal energy is becoming a hot topic, with many companies and locales looking to harness this energy source. Currently, Nova Scotia is considering the construction of the first in-stream tidal demonstration facility in North America in the Bay of Fundy. With some of the best tidal energy resources in the continent and new technology advances for tidal turbines, there is a tremendous opportunity to utilize this renewable energy resource.

The Electrical Power Research Institute calculates that this in-stream tidal energy facility could generate 300 MW of electricity and has many social and environmental benefits. The facility is expected to produce energy that is stable in cost and is not susceptible to the increasing prices and shortages of fossil fuels, thus benefiting the local economy. Air quality will not be compromised, nor will greenhouse gases be generate.

Nova Scotia is in the process of selecting the technology to be utilized at the facility and has narrowed down the options to three candidates. The finalist are Clean Current of Vancouver, Openhydro of Ireland, and Minas Basin Pulp and Power of Nova Scotia partnered with UEK Hydrokinetic Turbine.

“We are grateful for the shared desire today to help create a brand new industry,” said Energy Minister Richard Hurlburt. “And we are pleased to welcome some of the world’s most promising technology to our province. If we combine that technology with Nova Scotia’s offshore expertise, research capacity and enormous tidal resource, this can become a truly outstanding center of excellence.”

In-stream tidal technology utilizes energy of rising and falling tides. The source of this energy is actually the moon, unlike any other form of energy. Moving water currents produce kinetic energy, which can then be converted to electricity with turbines. Ideal sites have a concentration of tidal energy, such as bays or are located between land masses, making it easier to harness energy.

Currently, there are no commercial tidal energy projects in operation globally, but the race is on to harness this source of energy. The next few years will be interesting ones for the advancement of renewable energy technologies globally, in the race for energy solutions.

Road Salt Causing Contamination

snow on roadWhat might start out as one lick here and another lick there can turn into a full fledged salt addiction for woodland animals. Dear, porcupines, hares, birds, and other animals may all indulge in this habit. There is no shortage of salt to feed this addiction, with13 million tons applied to winter roads each year in the US. Sadly, this addiction can prove to be a deadly attraction.

Animals can be struck by vehicles while indulging their salt fix. Like many drugs, it can slow the reaction time of birds, causing them to be less alert around approaching cars .

“Birds get apathetic, they can’t fly off and that’s when they get schmucked by an 18-wheeler. So, while they’re getting hit by the cars, we believe the root cause is road salt,” said scientist Pierre Mineau.

Aquatic life is also at risk when melting snow gathers salt, finding its way to lakes and streams. Chloride concentrations can reach more than 1,000 milligrams per liter (mg/l), preventing the distribution of oxygen and nutrients. Environment Canada estimates that 10% of aquatic species are harmed by prolonged exposure to concentrations greater than 220 mg/l.

Vegetation is also effected by road salt, causing it to turn brown with dehydration. Salt intolerant species, such as Maple trees are disappearing from roadways. Vegetation as far as 162 feet from roads can be damaged. Because of the intricacy of the web of life, harm to vegetation can have a residual effect on wildlife.

Salt can also have an effect on health in humans although there is little evidence of salt addiction. The U.S. E.P.A. stated, “Especially since the construction of the interstate highway system, water contamination due to wintertime road salting has become an increasing problem.” Salt not only increases chloride levels in water, but can also increase the corrosion of pipes. This releases lead and other metals into the drinking water.

Many times this winter, I have seen salt trucks covering the roads with salt. Although this certainly offers a numerous benefits to the public, it does come with a price. Many states have been using alternatives to salt with success.

85 Year Old “War” Over Colorado River Water Ends

hoover_dam_pictures_t2700.jpgIt’s been going on since 1922, seven western states staking their claims on Colorado River Water. For years, a sometimes divisive battle has raged as Colorado, Utah, California, Arizona, Wyoming, Nevada and New Mexico all said they weren’t getting their share of the precious liquid.

It came to an end in Las Vegas, when representatives of the seven states inked their signatures to a 20 year water-use agreement that now supersedes the 1922 pact.

The plan resolves several legal issues among water agencies and formalized rules fostering cooperation during drought conditions now ongoing in the region. The states are promising consultation and negotiation before litigation on Colorado River water issues. What a concept.

Three lower-basin states, Arizona, California and Nevada will use the Lake Mead reservoir behind Hoover Dam to store water they won’t use or need right now. Thirty million people depend on water in that region, especially in Southern California, where 26 cities and water districts serve about 18 million customers. Read the rest of this entry »

Bottled Water Not So Hot for Economy Either, Report Finds

Mount ShastaEnvironmentalists already have good reason to despise bottled-water companies, but local economic development folks might now have reason to question the industry too. That’s the message from opponents of a proposed Nestle water-bottling facility in McCloud, California, a small community with natural springs fed by the glaciers of Mount Shasta.

McCloud’s defenders today released an economic study that casts a skeptical light on Nestle’s predictions that the plant would bring more local jobs and an improved local economy. Most of the promised jobs would probably be filled by people from outside the area, while others would be entry-level, low-paying positions. Furthermore, the report added, building a large water-bottling plant in a place known for its natural beauty could drive away some residents and businesses over time.

“The proposed facility threatens to consume one of the area’s most valuable assets: its water,” said Kristin Lee, an economist with the consulting firm ECONorthwest and one of the authors of the report.

ECONorthwest prepared the study on behalf of the McCloud Watershed Council, a volunteer-based residents’ organization working to preserve the quality of the region’s watershed. The group is fighting Nestle’s plan to build a one-million-square foot water-bottling plant in the former logging community, which has a population of about 1,200. If constructed, the McCloud facility’s size would make it the largest water-bottling plant in the U.S.

“It would be the largest building in Northern California,” said Brian Stranko, CEO of California Trout, a group that works to protect and restore wild trout populations in California waters. “You could fit every building in McCloud into it.”

The area’s environmentalists and local residents oppose the plant on many levels. They object to the McCloud Community Services District’s agreement to sell local water to Nestle at “far below” market value. They warn that Nestle’s contract would give the company control of local water supplies for 50, possibly even 100 years. They fear the facility’s impact on the environment, on downstream users of local water, on the region’s attractiveness for tourism and outdoor recreation. And, now, armed with the ECONorthwest report, they worry the plant won’t be as good a deal for the local economy as Nestle says.

That’s now the message they’re hoping to deliver to the McCloud Community Services District, which inked the original deal with Nestle and — they say — still retains the power to renegotiate the terms of its contract with the company.

“It’s not too late for the (district) to reconsider this contract,” said Sid Johnson, a member of the McCloud Watershed Council. “We’re not sure they’re aware of that.”

Nestle Waters is the world’s top seller of bottled water. As of 2006, it sold 72 different brands of bottled water — including San Pelligrino, Perrier, Aquarel, Ozarka, Zephyrhills and Deer Park — around the globe.
