1.The Water Resources Research Center (WRRC) is pleased to announce publication of the 2025 Arroyo. With the title, “Expanding and Diversifying Arizona’s Water Portfolio,” this year’s Arroyo describes the many ways Arizona is exploring to develop “new” water sources for a secure, sustainable supply. After outlining current water supply challenges, it focuses on four broad strategies: treating water, capturing water, transporting water, and exchanging water. Specific initiatives detailed include Advanced Water Purification, desalination, solar powered water filtration, modifications to dams and their operating rules, water harvesting, watershed management, groundwater recharge, pipeline projects, leasing water, and payments by some water users for others to use less water. Drawing from presentations given at the 2024 WRRC Annual Conference, “Implementing Water Solutions Through Partnerships,” this Arroyo offers a hopeful message based on evidence of progress made through the combined efforts of many.

2. Arizona Approves New Standards For Pollutants In Groundwater
KJZZ | By Bridget Dowd
The Governor’s Regulatory Review Council has approved new aquifer water quality standards.
The standards are Arizona’s legal safety limits for pollutants in groundwater. The changes include new or revised caps on seven contaminants like arsenic and uranium, which can harm human health at high concentrations.
If contamination exceeds those limits, the Arizona Department of Environmental Quality (ADEQ) can require corrective actions, like treatment, containment or cleanup.
According to ADEQ, more than 80% of Arizona residents rely on groundwater for drinking water, especially those in rural communities and private well households.
“This is a win for public health and Arizona communities that depend on groundwater for drinking water,” said Trevor Baggiore, ADEQ Water Quality Division director. “We are proud to deliver on our commitment to modernize these standards to reflect the latest science and federal regulations.”
They will take effect on Aug. 4.
3. How Will Arizona Deal With Colorado River Shortages? Cities Need A ‘Plan B,’ Expert Says. Kathryn Sorensen likes to compare the options for finding water rights in central Arizona with shopping for clothes. Some options, such as tearing out turf, are like thrifting: cheap but a little picked over. Others, like desalination, are like buying a tiny designer handbag, expensive and ultimately limited in its capacity. And then there are other options, which might involve buying or borrowing other people’s clothes, and those options involve politics.
Sorensen, director of research at Arizona State University’s Kyl Center for Water Policy, spoke June 5 to an audience of water managers, scientists and tribal leaders at the 45th annual Colorado Law Conference on Natural Resources in Boulder, Colorado. She laid out how cities and developers are struggling for more limited water resources in the area of the Colorado River Basin most vulnerable to water cuts: central Arizona.
“If cuts become deep enough, and there’s clearly a chance that will happen, I want to say in no uncertain terms, I am extraordinarily concerned that we will hit critical levels,” Sorensen said in an interview. “There are cities that rely on that (water) directly, and we need to make sure that those cities have a Plan B.”
The Colorado River, which provides 40% of water for Phoenix, along with most of Arizona’s largest cities, is experiencing low flows unprecedented in U.S. history. The federal government declared the first official shortage on the river in 2021. Maricopa, Pima and Pinal counties were the first to take serious cuts under an agreement struck decades ago to secure support for the Central Arizona Project Canal.
So far, those cuts have dried up farms in Pinal County, but most cities and tribes have stayed wet, in part because the Gila River Indian Community volunteered to conserve some of its water in Lake Mead.
That arrangement does not guarantee water after 2025, and the Colorado River Basin states are stalled in negotiations to define guidelines for how to manage shortage on a larger scale after 2026. slource;v Austin Corona, Arizona Republic.
4. If Trunp’s” Big Beautiful Bill” Passes Through Congress, it is projected to create a $2.4 trillion debt for the United States. Here is a graphical
representation that gives you some idea of how much money that might be. $2.4 trillion, represented by a stack of $100 bills, would be 1,514.4 miles high. As a reference, the distance from the Earth’s crust to the center of the Earth is 758 miles.
5. Health: New Tests Promise to Reveal the Secrets in Your Blood. A wave of diagnostic tests—some here, some coming—can identify cancer and Alzheimer’s at earlier stages and predict flare-ups of other conditions.
Blood tests have long been an important tool for giving doctors a picture of a patient’s health, from cholesterol levels to diabetes risk. Now new genetic science, Al analysis and other advances are providing even more sophisticated information from a simple vial of blood.
Testing for cancer
A wave of blood-based cancer tests are helping doctors to detect, manage and monitor various cancers in a less-invasive way. These new liquid biopsies, as they are known, use artificial-intelligence tools to recognize complex patterns and molecular signals—including tiny fragments of DNA shed by tumor cells and other cancer markers—that would be difficult or impossible to find using traditional methods. The information can help doctors monitor patients’ disease progression, detect recurrence and guide treatment decisions.
And with only about 60% of eligible adults now getting recommended colon cancer screenings, some doctors are excited about having a noninvasive screening option for patients who avoid colonoscopies or collecting their own stool sample.
Getting colon-cancer screening early is critical, but “you have to have a test that people actually take,” says Guardant’s chief medical officer, Dr. Craig Eagle.
Medicare began covering the Shield test for eligible beneficiaries last year, and the Department of Veterans Affairs began covering the test in March. Most private insurers haven’t yet included Shield in their policies, and Guardant says it is working on getting it included in clinical guidelines from groups like the American Cancer Society and the U.S. Preventive Services Task Force, which often guides coverage decisions.
Finding more than a single cancer
A number of companies are marketing or developing blood tests that can detect multiple types of cancer, pick up small traces of disease after treatment, check for recurrence and tailor treatments.
Grail’s Galleri test, intended for annual use, can detect signals for up to 50 types of cancer, including a majority that lack routine or recommended screening methods. Two large trials, one in the U.S. and one in the U.K., are investigating how well the test performs in detecting cancer when used alongside existing screening methods. And the Dana-Farber Cancer Center in Boston is studying use of the tests for individuals with elevated cancer risk due to inherited genes or familial history, and for military veterans.
Galleri has a 76.3% sensitivity for 12 of the deadliest cancers that comprise two-thirds of all cancer deaths and a false-positive rate of about 0.5%. So, of every 1,000 people who don’t have cancer, about five of them will have an incorrect positive result. Grail is pursuing FDA approval, which could broaden insurance coverage.
The lab-developed test has a list price of $949. Some employers cover Galleri, and the Tricare military health plan recently added it as a benefit. Medicare doesn’t yet cover the test, but will cover the costs for a study of 50,000 participants aged 50 and older. The goal: to assess outcomes such as the improvement in diagnosing advanced cancers.

7. June 11th Full Strawberry Moon. Seen on Wednesday, June 11th.
Strawberry Moon is one of the traditional names for the June Full Moon used by Native Americans — for them, June was the strawberry harvesting season. So the name is not based on the characteristics of the lunar appearance, but on the characteristics of the month. If you look at the names of other Full Moons, you’ll see that they’re also related to the natural characteristics of a particular month.
