UA Pharmacists working on mine tailings


The UA College of Pharmacy hosted an international conference this past week in Tucson looking at low-cost ways to stabilize mine tailings in arid environments. [right: Saginaw Hill mine tailings, near Tucson. Credit: Janick F. Artiola]

It was organized by the UA Superfund Basic Research Program, which is funded by the National Institute for Environmental Health Science. Results of the conference were not released immediately; they will be published as a collaborative 'white paper' journal article.

Among the projects at the SBRP is one to "develop a feasible revegetation strategy for the phytostabilization of metal contaminants in mine tailing piles in arid and semi-arid ecosystems."

Phoenix Mars Landers blogs

The University of Arizona' s Phoenix Mars Lander project has 9 blogs from researchers and students. The project has done an amazing job of keeping the public and other researchers engaged and informed on the project. My hat's off to the group.

Powering Arizona


The headline story in today's Phoenix-based Arizona Republic offers a preview of a report due to be released this week at a community forum on the state's options for electric power.

The report, "Powering Arizona: Choices and Trade-Offs for Electricity Policy," was funded by The Thomas R. Brown Foundation in Tucson.

I particularly like the paper's sidebar summarizing the pluses and minuses on each of the fuel types to provide electricity. [above: APS Cholla coal-fired power plant, Joesph City AZ; credit - scenicplaces.com]

It's also interesting to note other stories in the paper on energy. The U.S. and other oil consuming countries want the oil producers to increase production. We also call on rapidly growing third world countries to reduce subsidies for oil products because that increases demand and competition, pushing up prices for U.S. consumers. However, I didn't see a comparable demand being made of the U.S. to cut our use of 25% of the world's oil all by ourselves. Europe and others charge high fuel taxes to fund mass transit, reduce demand for oil, and make alternative fuels competitive. Should they blame the U.S. for keeping gasoline prices historically low, thus pushing up demand and causing the worldwide supply crunch and skyrocketing prices?

There are no easy answers to energy problems. Based on what I read this morning, the Powering Arizona report should be mandatory for everyone.

Geology jobs among winners in the economy


Jobs in mining and energy are among the "winners" in terms of growth, according to statistics based on a Labor Dept. report released Friday:

"Mining and oil and gas extraction:
Knowledge of minerals, geography and fuel extraction has been helpful in 2008. Mining support jobs have grown 3.6% so far, while the overall mining industry has expanded 2.3%. Jobs related to oil and gas extraction grew 2.1%. Key skills for such jobs include taking geological samples, exploring prospective sites, excavating pits, digging for minerals and tasks related to oil and gas extraction."

Thanks to geology.com for spotting this. [above: credit, Asarco]

AEG Arizona Chapter has a new geoblog


The Arizona Chapter of AEG (Association of Environmental and Engineering Geologists) started a blog this week at http://aegarizona.blogspot.com/.

The Chapter is only a few years old, starting out as part of the Las Vegas Chapter, but grew quickly and earlier this year became an independent chapter.

Water use for electricity exports

About one-third of the water used in Arizona to generate electricity is used for electricity sent out of state.

A study by Mike Pasqualetti, a professor of Geography at ASU, reported by the Arizona Water Institute newsletter, has found that 150,350 acre-feet (AF) was used in 2007 to generate electricity in , while only 98,732 AF were consumed to generate energy used in Arizona.

The amount of water embedded in our electricity exports can be seen in the diagram above.


Dr. Pasqualetti also found that about 22,000 acre-feet of water are also embedded in electricity that Arizona imports from Colorado and New Mexico.

Some reading this are going to immediately think that we should stop producing electricity that is sent out of state because it uses water. But we can look at energy production like any other item produced and exported. Most of what we produce here requires water in one or another. Three of the five "C"s in Arizona, Cotton, Citrus, and Copper, all are big water users and and also big exports. Even something that doesn't necessarily take a lot of water directly, like Raytheon's aerospace manufacturing, requires a huge workforce who boost the population and need water for their daily living.

There are huge challenges in trying to create a sustainable water economy in Arizona, but we have to be cognizant of how we use water everywhere. If we are opposed to using Arizona water being used to generate electricity that goes to California, are we equally opposed to watering citrus and pecan groves that feed those same people?

We have some serious conversations about water ahead of us in this state and elsewhere.

APS seeks alternative energy, including geothermal



Late yesterday, Arizona Public Service (APS) announced they are seeking proposals for renewable energy resources to meet a portion of its overall resource needs. The eligible technologies for this Renewable RFP include biomass/biogas, landfill gas, geothermal, solar, wind, hybrid wind and solar, renewable natural gas and hydropower technology.

Minimum Annual Energy per project (MWh) = 35,000

Targeted Annual Energy (MWh) = 250,000 - 1,000,000

Geology is focus of Arizona state quarter


Not to belabor this, but Arizona's premier geologic feature, the Grand Canyon, is the theme of the new state quarter just released. Of course, there is that pesky saguaro cactus, blocking the view of the rocks, but what can you do?

Will choice of President affect Resolution Copper mine?


Mining columnist Jack Caldwell [right], posted a piece today saying that the Resolution Copper mine will have a better chance of being developed if John McCain becomes president. This is apparently extrapolated from the fact that Sen. McCain and fellow senator John Kyl of Arizona, last year introduced legislation in Congress for the land exchange that Resolution needs to go forward.

The land exchange is supported by Gov. Napolitano and a variety of local, environmental, and recreational groups. It is opposed by the San Carlos Apache Tribe.

Martian dust and sand under the microscope

NSF does the Diet Coke and Mentos experiment


You've no doubt seen the immensely popular YouTube video of choreographed 2-liter Diet Coke bottles erupting when Mentos are dropped in. It reminds all of us of our first baking soda volcano science project, only on steroids.

Well, now the National Science Foundation has its own video that explains why it works and what happens if you use different flavors of Mentos.

Hint, Mentos porosity is a key factor. And don't you love the helmet?

BHP: no need to sell assets in Rio Tinto merger


The CEO of BHP Billiton, Marius Kloppers, told the Melbourne Mining Club today the company sees no need to sell assets to win regulatory approval for its takeover of Rio Tinto.

For the past few weeks I've been speculating that the combined company might have to sell the Resolution Copper project near Superior if the merger went through, based on comments that BHP leaders were making.

However, Kloppers did not rule out the possibility that asset sales may still happen. Some of the biggest concerns are from the Chinese who worry over the combined company's concentration and pricing power of iron resources, a commodity of great importance to the booming Chinese industrial economy.

Google Maps "Core Viewer" beta test


The EarthScope project is beta-testing Google Maps new Core Viewer software which is described by Discovery News.

They have core from the San Andreas fault drill hole (SAFOD) posted online.

I'm eager to try out the features and capabilities for the Core Viewer application.

Environmental groups oppose sale of Asarco assets



A group of U.S. environmental groups is asking the Department of Justice to prevent the sale of Asarco's assets to a subsidiary of Vedanta Resources, because they claim that company and its affiliates have a worse environmental record than Asarco.

USGS: educate but not advocate


USGS Director Mark Myers told an Arizona Geological Society meeting in Tucson last night that credible scientific baseline studies are essential to making rational decisions about our environment, lands, and resources. He noted there are strongly competing interests for multiple uses of lands, including energy, minerals, agriculture, water, recreation, preservation, and natural habitat.

He told the crowd of about 50 that humans already modify 40-50% of the ice-free land and use 54% of the available fresh water of the globe.

The U.S. has never done an integrated census of our surface and ground waters, and it's been 30 years since any water census was done.

In 2003, the last year we have data for, the U.S. produced 3,000 million tons of minerals, mostly aggregates and building materials. In China, the government doubled the size of the geological survey to deal with the increasing demands for resources and the environmental issues. In the U.S., we are reducing the size of the USGS minerals program.

Mark sees a change in philosophy starting to emerge in Washington; that political leaders are seeing environmental security (in the broad sense) strategically important. However, that has not translated into funding for agencies like USGS.

Tim Marsh, with Bell Resources, challenged Mark during the Q&A session, over the USGS' role as taking a broad-based view of the environment. He questioned why USGS is not serving as an advocate for mineral development.

Mark argued back that land management agencies need reliable baseline ecosystem data to allow mining to go forward, and USGS can provide that if they are not viewed as biased. Land managers need integrated scientific information to decide among competing interests.

The USGS role is to educate, but not advocate positions to decision makers. Well-intentioned, but poorly informed lawmakers are at risk of making bad decisions unless they have peer-reviewed, credible baseline scientific results to work from.

ADMMR's mining scam library applauded




A story on mining scams by well-known mining reporter and blogger Jack Caldwell declares:

"The Arizona Department of Mines and Mineral Resources at www.admmr.state.az.us/Info/scams.html has the best collection of documents detailing the many mining scam schemes that abound and telling you how to avoid being caught. If you have any doubts about the veracity of the offer, look at these documents, and better still consult a trusted investment lawyer, investment consultant, or mining consultant."

Cenral Arizona Geology Club


The recently formed Prescott Geology Club has become the Central Arizona Geology Club with a website/blog at http://centralarizonageologyclub.blogspot.com/

They are organizing a gold panning field trip this Saturday [right: Lynx Creek withdrawal area, credit US Forest Service]. Trip leader Roy Row describes,

"Water level in Lynx is dropping fast, however, I believe we will have sufficient water for Saturday.

I want to pan in Lynx Creek @ Stoneridge Dr.

We will meet @ Hwy 69 & and Stoneridge. Make the turn, S, onto Stoneridge and proceed about 200 yds to a street that turns, R , into the new Crossroads. I will be waiting there in my 1993 Green Toyota Land Cruiser ( which is well AZ pin stripped). Once all have assembled we will make the short drive to the parking area. There will be a short hike down to the creek, maybe 5-600 yds from where we park. All should be able to negotiate.

I suggest wearing rubber boots or "crik shoes", bring along a pill vial or similar small container to capture your Gold. For those who wish to "dig", bring a shovel.

I anticipate this outing to be no more than 2 hours. Due to the warmer weather, we will meet @ 8:00 am."

USGS director bemoans loss of knowledge infrastructure


USGS Director Mark Myers is worried that the loss of the nation's knowledge infrastructure over the last 40 years has damaged our ability to make good public policy based on sound science. He made this and other wide-ranging comments at an informal breakfast meeting this morning at the USGS offices on the UA campus in Tucson.

He also expressed frustration with the lack of incentives and the uncertainty facing students who might consider science careers. Business and banking are attracting the nations 'best and brightest.'

A third note is the transfer of responsibility for many of the nation's domestic issues from traditional government agencies to the Dept. of Homeland Security, driven by budget constraints in agencies like the USGS, while large new resources go to DHS and related programs.

UA President Robert Shelton and a small number of UA deans, department heads, and leading researchers were also in attendance. Mark is in town to tour the USGS operations and meet with staff, then will speak at the Arizona Geological Society dinner meeting tonight (I'll blog about that talk tomorrow).
