Over the last several weeks we have seen flooding, first along the Mississippi, and now in North Dakota and reaches of the Missouri River watershed. Too much hydrology, as Gary Burchard (long-term Tucson Chapter member) says on our AHS LinkedIn page, as the river system reworks the floodplain. We are reminded of the fundamental power of surface water to alter the physical and certainly cultural environment within the reach of the stream. We have also seen the horrible devastation wrought by flame in the higher elevations of the semi-arid Southwest. Too little hydrology here; I heard an estimate of 1% relative humidity in the forest at the beginning of the huge Wallow fire. Denuded slopes now dominate over half a million acres from that one fire alone, and others yet burn. The monsoon season approaches, should the standard annual cycle hold. The hydrological consequences could be profound. Where have we seen this before? The field trips planned for this year’s Annual Symposium in Flagstaff, September 18-20, will provide a unique and incredibly timely educational opportunity to visit the locale of the last major fire in northern Arizona. The Schulz Pass Fire produced debris flows and flooding, reaching farther down the fan than anyone had expected. If you want to know the answers to what is going to happen hydrologically after the fires, this field trip is your chance to see it first-hand. Plus the Beaver Creek tour will educate you on research in the watersheds of the forest. These two field trips alone make attendance at the 2011 Annual Symposium in Flagstaff an absolute must for anyone interested in the timely topic of watersheds. Yet even more will be available in the excellent technical sessions now being planned—and it isn’t all surface water. A lot of topics are covered under the rubric of watersheds. The month of July is your last opportunity to sign up at the early registration rate. If you are a consultant, you need this knowledge this year. The new fiscal year has started for state and local governmental entities. Get your training requests in now to attend this important conference. Go to http://www.azhydrosoc.org/registration.html to register online (the most convenient way). Now is the time. Alan Dulaney, AHS Corporate Board President, 2011 Is a breath of fresh air moving through the empty cubicles at ADWR? Mike Lacey, a long-time AHS member and principal at Fluid Solutions, Inc., has been selected as the new ADWR Deputy Director. Mike brings a depth of hydrological and managerial expertise to the agency that should be much welcomed. As one of two Assistant Directors, Mike Johnson comes from the surface water side of the agency, and should bring a renewed focus on engineering to ADWR. Tom Buschatzke will start as the other Assistant Director on July 18, in charge of planning. Tom comes from the City of Phoenix where he was Senior Water Advisor, with a wealth of knowledge concerning the Colorado River and the Central Arizona Project. Tom has participated in almost every major water initiative over the last several years, and will bring an interesting new slant to several programs at the agency. A new supervisor for adjudications projects and a new ombudsman/legislative liaison have also been appointed. New brooms sweep clean. It could well be that many programs at ADWR will be revised and revamped to fit current exigencies. I would look for a re-organization at ADWR sometime over the next few months, and I think the staff will welcome it. I don’t think it will be business as usual—these new guys will not long tolerate stale thinking. And this is a good thing for the agency. Cruel cuts in the budget have brought ADWR to a turning point; things can never again be the same as they were in years past, and to remain vibrant, the agency must change and adapt. The new management team could just be the guys to bring that change off. I wish them much success. Alan Dulaney, AHS Corporate Board President, 2011

Exhibitors: Bill Johnson Equipment Co. Engineering and Environmental Consultants, Inc. (EEC) Conducted by Dennis Helsel, PhD 2011 Arizona Hydrological Society 24th Annual Symposium Workshop 1:30 pm to 5:00 pm MST, September 20, 2011 High Country Conference Center 201 West Butler Avenue Flagstaff, AZ 86001
Measurements of trace chemicals in environmental media (water, air, soils, biota) frequently result in values reported only as less than the laboratory reporting limit (“less-thans”, “nondetects”, and “qualified values”). The most commonly used method for incorporating nondetects is to substitute one-half the reporting limit and continue as usual. Unfortunately, this approach may obscure patterns and trends that are present or create patterns and trends that are not actually present in the original data. This approach is fraught with error. Two easily implemented methods that avoid the problems with substitution produce summary statistics (mean, median), perform hypothesis tests, and compute regression models for data with nondetects. These will be discussed in detail. More complex procedures from the field of survival analysis will also be introduced. These procedures explicitly handle data with multiple detection limits. This workshop is based on Dr. Helsel’s new textbook Statistics for Censored Environmental Data (first edition was titled Nondetects And Data Analysis), published by Wiley. A CD including a presentation file and other relevant materials will be provided at the workshop. Below is just one example of the problems inherent in substituting one-half or other fractions of the detection limit for nondetects. These fabricated values are “invasive data” unlike the original values. They can take over and obscure the signal present in the original observations. Substitution is not neutral.
Original data prior to censoring. True correlation equals 0.81. From Statistics for Censored Environmental Data (Helsel, 2012).
Data after censoring at detection limits of 1 and 3 ppb and substituting ½ DL (shown as open circles). These invasive data form flat lines at one-half the detection limits, lowering the correlation to 0.55. From Statistics for Censored Environmental Data (Helsel, 2012).
Workshop Cost: $50 PLEASE NOTE: You do not need to be registered for the AHS Symposium to attend this workshop!
An additional, in-depth 2-day Course will be offered by Dr. Helsel after the Symposium! Untangling Multivariate Relationships – register online! Turn confusion into recognizable patterns UMR covers the multivariate methods of primary interest to environmental science, focusing on what each method is designed to do, when to use them, and when not to. Methods include principal component analysis (PCA), multidimensional scaling, cluster analysis, correspondence analysis, and tests for group differences and trend analysis based on multiple variables. Included are procedures for incorporating nondetects without substitution. Example data sets are analyzed by each student in class. By the end, the choice of which method to use, and how to use it, simply makes sense. September 21-22, 2011 Flagstaff, Arizona A special discount is being offered to AHS Symposium registrants – Registration cost for the 2-day course is normally $795, but for AHS Symposium registrants it will be $650!

May 2011 Meeting Summary - Write up provided by Shane T. Clark. Shane has been an AHS member since 2009 and has been the Tucson Chapter Secretary (since January 2010). He is soon to graduate from the University of Arizona with a B.S. in Watershed Hydrology. "Beneficial Use of Storm Water" On Tuesday, May 10th, 2011, the Tucson Chapter hosted a special guest lecture by Evan Canfield who is the Chief Hydrologist for the Planning & Development Division of Pima County Regional Flood Control District (PCRFCD). This talk was held at the offices of Montgomery and Associates, 1550 East Prince Road, Tucson. Here is a brief summary of his lecture for those AHS members unable to attend: Evan Canfield gave a presentation on optimizing recharge efficiency. Evan spoke about the concerns of water scarcity, storm water quality, the urban heat island, groundwater recharge, and flood mitigation which have resulted in greater interest in beneficially using storm water. Evan provided an assessment of the beneficial use of storm water for the City/County study and found that lot and neighborhood scales provide the greatest opportunities for storm water harvesting. These opportunities provide primarily a source of water to grow drought-tolerant deep-rooted plants. The results of the study recommended a shift toward more decentralized storm water management practices, such as water harvesting in right-of-ways and greater use of passive water harvesting on individual lots. Along with other interested parties, the PCRFCD recently conducted a Low Impact Development (LID)/Green Infrastructure (GI) workshop to begin the process of integrating decentralized storm water management techniques into our environment. The workshop events agenda items were: 1.) Dialog, 2.) Current efforts, 3.) Discuss/brainstorm, 4.) Planning for future work. Evan jokingly summarizes these efforts by stating “Thou shall implement LID”. Additional suggestions were to implement AZPDES permits, more wide-spread use of the City of Tucson’s water harvesting ordinance, and active flood control management. Since the current methods were developed to address water quality concerns in more humid areas, such as the eastern United States, integrating them into an arid environment is a challenge. However, the District PCRFCD is planning to integrate these methods into an upcoming neighborhood-scale water harvesting manual and an update of the detention/retention manual. The AHS Tucson Chapter extends a very warm thanks to Evan Canfield for his informative presentation! Additionally, the Tucson Chapter would like to thank Montgomery and Associates for providing the space so that this monthly talk could be held!

Abstract The copper mining revival in Germany and Poland depends on the famous Kupferschiefer-type Cu-Ag deposits, which have been well known in Central Europe since before the Middle Ages when the local aristocracy made their riches from copper and silver mining of the outcropping Kupferschiefer. Today, the Polish Kupferschiefer-copper mining company KGHM is the fourth largest copper producer in the world. New discoveries in Germany may develop into the next large copper mining district. Kupferschiefer Cu-Ag-PGM deposits show specialized mineralogical aspects that have caused major scientific arguments. Today we know that the Kupferschiefer black shale is of upper Permian age. The development of the metallogenic concentrations lasted for at least another 25 million years. The source of the metals and their specific or rather unspecific, but predictable placement in monotonous, but diverse geological units have mystified many researchers, from the “syngenetic” to the “epigenetic” school of thought. The deposits are characterized by a geochemical signature of parallel metallic zones of varying composition. They are relatively thin in vertical dimension and vast in lateral extent. The Kupferschiefer strata are essential as a geological cap for rising and laterally migrating metal solutions. pH, Eh, rock permeability, geologic environment, geothermal fluids and time are the controls of ore deposition. The occurrence of the deposits is always defined by consecutive, sub-parallel lateral bands starting with the “Rote Fäule” hematitic iron which usually is present over a very large lateral area. The next metallogenic “band” is that of economically interesting copper-silver sulfides containing silver and gold and PGM inclusions - from chalcocite to bornite to chalcopyrite with an appreciable amount of organic carbon. This is followed by overlapping bands of lead sulfides, zinc sulfides, and pyrite which grade into the barren, black Kupferschiefer shale. The understanding of these geochemical and metallogenic markers can lead geologists to new discoveries of very large copper-silver deposits that will keep producing for decades to come.

WASHINGTON - The Obama administration said it intends to place a 20-year ban on new mining claims on 1 million acres bordering the Grand Canyon, moving to protect an area that is a critical water supply to the Southwest and where uranium-mining claims have jumped 2,000 percent over the past seven years. The ban would extend a two-year moratorium established in 2009 but set to expire July 20. Interior Secretary Ken Salazar said Monday that the Interior Department will extend it until December to allow time to complete the steps needed to enact the 20-year ban. Mines that are currently operating would be able to continue working. Salazar emphasized the need to protect the Colorado River watershed from possible uranium contamination. The river provides drinking water to several major Southwestern metropolitan areas, including 19 million people in Southern California. "What drives us first is protecting the arteries of lifeblood, of water" in the area, Salazar said. Environmentalists also said the decision would keep the Grand Canyon panorama from being gradually industrialized.
