EPA orders the Air Force, Arizona National Guard to clean up groundwater contamination

PHOENIX — The U.S. Environmental Protection Agency is demanding the U.S. Air Force and Arizona National Guard take action as concentrations of toxic “forever chemicals” are increasing in the groundwater in a historically contaminated area in the south side of Tuscon, Arizona.

The EPA found the pollution came from the nearby military properties and ordered them to clean up the contamination. High concentrations of PFAS, or per- and polyfluoroalkyl substances, were detected in Tucson’s groundwater near the Tucson International Airport at the National Guard base and at a property owned by the U.S. Air Force.

The contaminants threaten the groundwater extracted at a water treatment run by Tucson Water in the Tucson Airport Remediation Project area, known as TARP. That water was intended for drinking, the EPA said in its May 29 order.

Samples taken at the treatment plant showed concentrations of PFAS as high as 53,000 parts per trillion, which is 5,300 times the allowable amount. The limit allowed in drinking water ranges from 4 parts per trillion to 10 parts per trillion, depending on the type of PFAS.

To prevent the contaminations’ further migration towards city wells, the agency gave the Air Force and the Air National Guard 60 days to develop a remediation plan. The Morris Air National Guard Base leading the remediation project did not respond to the Arizona Republic, part of the USA TODAY Network, and its requests for comment.

Tucson Water, the city’s water utility, said the wells impacted by the contamination are not in service and customers are not being served contaminated water. But with concentrations of PFAS continuing to increase, the issue remains a concern for the city.

“When we have an area where the water quality is impacted and we’re not able to serve that to customers, that is an added cost. It really diminishes the resource that we have available,” Natalie DeRoock, a Tucson Water spokesperson said. She noted that other than the Colorado River water the city pumps in, Tucson depends on groundwater, a finite resource.

The water utility stopped serving water treated at TARP to residents in 2021, when increased PFAS levels caused the plant to temporarily shut down as the filter system sequestering the contaminants could not handle the increase.

What are PFAS? ‘Forever chemicals’ are common and dangerous.

What will remediation look like?

DeRoock said the water treated at the TARP facility exceeds state and county standards for clean water, so the city decided to divert the water to the Santa Cruz River rather than use it as drinking water. She said the city wanted people to feel confident about their drinking water, and instead decided to use that water to maintain the water levels in the Santa Cruz River and to help with the riparian habitat restoration.

As part of the EPA’s order, the remediation plan submitted by Air Force and National Guard must ensure the water is clean enough to be used as drinking water.

“With appropriate response, Tucson Water would be able to resume delivering water from the TARP facility to the drinking water system, as it was originally designed to do,” said Joshua Alexander, a spokesperson for the EPA.  

Alexander said remediation is a complicated process that could take years. It could require the creation of new water treatment facilities or the modification of current existing facilities to treat an increased volume of water.

He noted several technologies that successfully remove PFAS from water, including granular activated carbon, a filtration system that uses carbon to remove contaminants from drinking water. He pointed out that new technologies are also being developed worldwide to remove PFAS from drinking water.

PFAS is a danger to public health

PFAS are long-lasting chemicals that have been used since the 1940s in a wide range of industries and products — from fire retardants and popcorn bags to personal care items and clothing — that can now be found globally in water. PFAS are considered hazardous substances that can cause severe health issues with long-term exposure, even in low traces.

Studies show PFAS exposure can negatively impact the body’s immune and cardiovascular systems, as well as vaccine response. Studies have also linked oral exposure to PFAS to adverse health effects on the liver, the kidneys, and the immune system, and cancer, according to the EPA.

Though residents in Tucson’s south side don’t receive water from TARP’s contaminated wells, past exposures and their effects worry residents. Many contend broader health screenings and compensation are still due.

Site has long history of contamination

The area has a history of contamination from decades of defense and industrial activities. The Tucson Airport Remediation Project area is a superfund site contaminated with several pollutants.

One of the primary contaminants is trichloroethylene, or TCE, formerly used as a general-purpose solvent and degreaser. Another contaminant found at the site is 1,4-dioxane, which was used as a stabilizer to enhance the life of the solvent bath for degreasing manufactured parts.

These and other hazardous materials were disposed of at the airport and eventually began seeping into the groundwater, contaminating the regional aquifer. The area was declared a superfund site in 1983 and listed as a national priority area for long-term cleanup.

Other contaminants at the site include dichloroethene, chloroform, and chromium. A carcinogenic compound, polychlorinated biphenyls, and metals contamination were also found in some soils on the site. According to the Arizona Department of Environmental Quality, the “contaminants of concern” may change as new data becomes available.

Arizona prisons director defends practice of lowering inmate custody level

Arizona prisons director defends practice of lowering inmate custody level


PHOENIX (AZFamily) — Ricky Wassenaar was already serving 16 life sentences for his role in an escape attempt and hostage standoff at the Lewis Complex prison in Buckeye in 2004. For the past 20 years, he remained mostly out of the limelight, serving his time.

But in April of this year, Wassenaar attacked three inmates in the Cimarron Unit of the state prison in Tucson, killing them, and sparking a controversy over how he was able to carry out the murders and how he had access to other inmates in the first place.

“I would have killed at least seven. My goal was at least seven,” Wassenaar told True Crime Arizona’s Briana Whitney, in a phone interview. She said he seemed excited to talk about it, bragging that he had provided a service, because the inmates he killed were sex offenders.

According to Wassenaar’s inmate profile, at the end of 2024, he was moved out of maximum security, where he had been for decades, and into close custody, which is a slightly lower level of security.

“He was max custody and then he was put out in close custody, which means he gets to walk among them (other inmates),” said Rodney Carr, who is a former warden in the Arizona prison system.

He left the Arizona Department of Corrections, Rehabilitation and Reentry after Gov. Katie Hobbs hired Ryan Thornell as the new director. Thornell came to Arizona from Maine, where he was deputy commissioner of a prison system a fraction the size of Arizona’s.

“I worked for a lot of directors and not always that I agreed with. But that’s my job. Well, with him it got to the point where I couldn’t,” said Carr.

Carr and another former warden, as well as several correctional officers, reached out to Arizona’s Family Investigates with similar complaints: that the department under Thornell’s leadership was moving maximum security inmates into close custody, where it costs less and requires fewer correctional officers to oversee the inmates.

“Under the way they’re managing maximum security inmates in a closed custody environment, staff are going to get hurt,” said Carr.

In an interview with Arizona’s Family Investigates, Thornell said he is moving inmates out of maximum security. “That is absolutely something we are doing. Just like every other department of corrections across the country must do. It’s a practice and we are doing that here,” said Thornell.

He said 90 to 95% of inmates who are in custody will eventually be released into the community, including those in maximum security. And Thornell said keeping them in maximum security the entire time they are in prison is not good for the community once they are released. He said the effect the isolation of maximum custody has on inmates is real and often negative.

“How can I say that somebody in max custody is OK to release into local Arizona, but they’re not OK to release into a close custody yard that still has fences or razor wire?” he said.

When asked if it was a mistake to take Wassenaar out of maximum custody, Thornell said no, but he couched his answer.

“Hindsight is always 20/20, right? So, knowing what I know today, should we have moved him out of max custody? Yes, we should have. Would I do it knowing the facts that I have at my disposal today? Knowing what he did then? No, I wouldn’t. But the practice was sound. It’s still a sound practice,” he said.

Thornell acknowledged that the number of violent incidents in close custody has increased, but he denied that it was the result of max-custody inmates creating more problems.

“It’s easy for a warden, a former warden, to come forward and say, ‘20 years ago, that’s not how we did it.’ Well, 20 years ago, nobody cared who we were releasing back into the community,” said Thornell.

Arizona lawmakers demand answers over Phoenix immigration court arrests

Arizona lawmakers demand answers over Phoenix immigration court arrests


PHOENIX (AZFamily) — Some Arizona lawmakers are demanding answers on what has been happening outside a Phoenix immigration court recently.

On Wednesday, four Arizona Democrats sent a letter to the Department of Homeland Security Secretary Kristi Noem and ICE Acting Director Todd Lyons. It came from Sens. Mark Kelly and Ruben Gallego, as well as Reps. Yassamin Ansari and Greg Stanton.

The letter comes after tense protests last week. For two days straight, ICE agents were at Phoenix immigration court, arresting people there for routine hearings and putting them into vans. That second day turned chaotic with protestors and officers getting physical.

“That pattern of dismissal and detainment kind of slowed down towards the end of the week, but unfortunately, today we did see more people detained at the immigration court,” said state Sen. Analise Ortiz, a Democrat from the West Valley.

She has been showing up to immigration court to support migrants at their hearings, and says ICE was there again on Wednesday, but it was different this time. “People were actually being told they could leave the courthouse, so they were driving off of the property and then being stopped and detained down the street. Someone relayed to me that a toddler was detained. This is just horrible, and this is inhumane,” said Ortiz.

The letter poses three main questions, with the first being how many people has ICE arrested and detained at an immigration court during the week of May 19 and how many have been placed in expedited removal?

The second asks for copies of all guidance and written directives associated with this recent ICE action, and the third asks how ICE is complying with requirements for screening individuals for fear of persecution.

The letter also says the Democratic lawmakers believe tactics like this make the immigration process less fair and efficient and undermine the Trump administration’s goal of targeting criminals who are public safety threats.

“A lot of these individuals who are in deportation proceedings (or) immigration proceedings, they don’t have a criminal history,” said immigration attorney Sheree Wright with IBF Law Group.

She has been volunteering to advise migrants at their hearings. “When it comes to safety, these are not criminals,” said Wright.

Arizona’s Family also spoke to a former Phoenix-based ICE agent who was in the field for 22 years. He wanted to remain anonymous.

The former agent said arrests like the ones at the immigration court are not new. He also said they are safer for the public, the officers, and the detainees because there is a screening process at places like court buildings. According to the former officer, when they detain someone, they often go through what is called “custody redetermination” to see if the migrant should continue with their immigration proceedings or be placed in expedited removal.

Takeaways From Arizona State Baseball Tournament Draw

Takeaways From Arizona State Baseball Tournament Draw


The Arizona State baseball program is officially tournament bound.

The Sun Devils – coached by fourth-year head coach and program alum Willie Bloomquist – were officially selected to be the three seed in the Los Angeles regional on Monday morning.

With that, the selection ended several days of nervous waiting after the program sputtered to end the season.

Ultimately, the rough finish is in the rearview mirror now and the Sun Devils are looking to make the most of this chance – here are three takeaways for the weekend ahead:

Advertisement

This one is obvious – the Sun Devils are in a region with the host in 15th seeded UCLA, the second region seed in UC Irvine, and Mountain West champs Fresno State.

UCLA and UC Irvine are battle-tested over the entirety of the season, while Fresno State has picked up play as of late despite only putting together a 31-29 campaign to this point.

The region will be a challenge for the Sun Devils, but it isn’t insurmountable…

The Sun Devils have the talent to win the region – and UC Irvine’s recent run of opponents leaves reason to be concerned that the Anteaters aren’t currently conditioned to compete with power four competition despite having proven they can defeat high level programs this season.

UCLA also is one of the lower national seeds that received the opportunity to host a regional – it doesn’t seem insurmountable for the Sun Devils – who boasted the best offense across the entire Big 12 – to capture some magic once again and make a serious run.

It feels as if a win in the opening matchup with UC Irvine is a must however, which brings the last takeaway into the fray.

This Arizona State baseball team truly has the ceiling of a College World Series squad – but also the floor of a squad that goes winless in the tournament.

While it would be unlikely for the Sun Devils to drop an elimination game to (presumably) Fresno State, a fifth loss in as many games could potentially prove to be too much for a team that entered the season with so much promise.

The opening game of the Sun Devils’ tournament experience is set for Friday night at 6 P.M. Arizona time – the game is set to be broadcast on ESPNU.
