Reflections: On Wicked Water Problems 
Although my spring-summer sabbatical lecture tour did not take place as planned due to COVID-19, I did deliver more than a dozen lectures and participated in several programs and interviews. My topic of wicked water problems was the most requested and one on which I will continue to focus. Not only does this topic afford me an opportunity to explore significant water challenges at varying geographic and geopolitical scales, it enables me to focus on the process for forging pathways to addressing them.

After a wildfire, monsoon rains bring threats as well as blessings. While supplying much needed moisture, downpours can launch damaging debris flows from fire-scarred slopes. In a July 13, 2020 post to the Arizona Geology e-magazine, researchers discuss an ongoing project to answer a very timely question: "After a wildfire, how intense does rainfall need to be to cause a debris flow?" Researchers Ann Youberg (AZGS), Luke McGuire (UArizona Department of Geosciences), and Francis Rengers (USGS) are installing instruments in wildfire burn scars to monitor rainfall and record the timing and velocity of flood and debris flows. The data will help elucidate how landscapes scarred by wildfires, such as the recent Big Horn Fire in the Santa Catalina Mountains, respond to monsoon storms. According to the blog post, the results of this research will provide valuable information for the National Weather Service and state and local warning systems.

ag-econCALS Posts Agricultural Economy Profiles

A collection of new fact sheets containing synthesized county-level data from the 2017 Census of Agriculture is available online from UArizona College of Agriculture and Life Sciences. These profiles of all 15 Arizona counties offer the most recently released data on agricultural production, water use, and regional economic context in a standard, accessible format. As the data show, agriculture plays a pivotal role in county economies and the management of land and natural resources. The authors, Dari Duval, Ashley K. Bickel, and George Frisvold, created these county profiles as part of the MAP (Making Action Possible) Dashboard, an initiative of the Eller College's Economic and Business Research Center focusing on the economy of Southern Arizona.

Twenty-five 4th-12th grade teachers are echoing the headline's sentiment after participating in APW's online AquaSTEM Rainwater Harvesting System Design Academy. This 6-week professional development workshop started with teachers exploring extreme heat in our community, which led them to design a rainwater harvesting system to grow shade with available rainfall. Each week the teachers participated in a one-hour zoom lecture that introduced them to weekly topics and assignments. Just as their students will do, teachers completed work that included inspecting their site, analyzing soil, quantifying the amount of harvested rain, selecting plants, calculating watering requirements, performing a water budget, sizing a basin, and sketching their design. As teachers moved through the iterative engineering design process, they made mistakes and re-designed. One teacher commented, "This process is eye-opening and the tools are excellent. I look forward to completing the course and making more errors! I am learning for sure and can see how to impart some knowledge to students as well." At the culmination of the class, the teachers presented their final designs for peer review. They all agreed that the class was "challenging" and "fun" as highlighted in the word cloud. A few other teachers, highlighted on APW's Facebook page, are taking the opportunity to install their designs at their own homes

MonsoonMonsoons Bring Harvesting Opportunities
The monsoons are here! As clouds dance across the state, Arizonans look skyward: anticipating, predicting, and tracking. There is a lot of rainfall variability, so sometimes we find ourselves green with envy as another neighborhood gets the rain, but at other times we are happily rewarded with a downpour. One of the great delights for water aficionados is watching our rainwater harvesting in action. Whether observing cisterns fill or basins pour into one another, watching water flow and nourish our landscape is one of the great joys of summer. There are many resources on the internet for designing and installing rainwater harvesting systems. You can find resources for evaluating your harvesting potential by using the WRRC Water Harvesting Assessment Toolbox or you can take a Zoom water harvesting class through the Pima County Cooperative Extension Smartscape program. If you have been thinking about creating or improving your rainwater harvesting system, now is the time to go for it. During monsoons you can construct your system, try it out, and then adjust for the next deluge.

AWRAAWRA Publishes Open-access IMPACT on Water and COVID-19
IMPACT, a journal of the American Water Resources Association (AWRA), spotlights water and COVID-19 in a new special issue. As editor of this special issue, Lisa Beutler, Stantec Consulting Service Inc., has collected a wide range of articles on water topics related to the COVID-19 pandemic. Because of the water sector's unique role in the fight against this novel coronavirus, the special issue features the experiences of water professionals who are working toward water security, water supply safety, wastewater surveillance, and supply and sanitation justice. Beutler, the past president of AWRA, is known to
Weekly Wave readers for her WRRC annual conference presentation and her WRRC newsletter article on wicked water problems. In this issue of IMPACT, she takes up the concerns of water and wastewater treatment practitioners, including coronaviruses in sewage and wastewater treatment plants; coronavirus removal and inactivation by water treatment; and progress in using wastewater for COVID-19 surveillance. In addition, an article focuses on lessons from Flint, MI, about the intersection of racial and social inequality with pandemic risks and impacts. Another friend of the WRRC, William M. Alley, along with co-author Charles A. Job, use an assessment of COVID-19 risks to drinking water from private wells-risks that are low--as a reminder of the importance of proper care and maintenance of wells and septic systems in protecting against all types of pathogens. Also in this special issue, Beutler interviews Alley and his wife and co-author Rosemarie Alley about their new book, The War on the EPA: America's Endangered Environmental Protections.
