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.

Taking Stock: How Arizona men’s tennis is looking under coach Clancy Shields


The offseason is here, with all of Arizona’s sports done for 2023-24 season and the 2024-25 campaigns still a little ways away.

Which makes this a great time to step back and see how all of the Wildcats’ programs are doing, especially with the impending move to the Big 12 Conference.

Over the next few weeks we’ll take a look at each of the UA’s men’s and women’s athletic programs to see what shape they’re in and what prospects they have for the near future. We’ll break down each team and evaluate how it is performing under its current coaching staff, looking at the state of the program before he/she arrived and comparing it to now while also looking at the upcoming debut in the Big 12 and beyond.

Next up: Clancy Shields’ men’s tennis team

How it looked before

For the longest time, men’s tennis had been one of those sports that Arizona participated in but never really competed in. From 2011-16 the Wildcats didn’t have a winning record, going winless in Pac-10/12 play all but once during that stretch.

But when it came time to make a coaching change, athletic director Greg Byrne made one of the most underrated hires of his tenure in Clancy Shields. A young, up-and-coming coach from Utah State who was Mountain West Coach of the Year in 2016, Shields came to Tucson with a vision to turn Arizona into one of the top programs in the country.

It took a few years, with the UA going winless in Pac-12 play his first two seasons, but in 2019 it broke through with an NCAA Tournament appearance and it’s been nothing but up since.

Where things stand now

Arizona has reached the Sweet 16 in three of the last four seasons, hosting the first weekend the last two years. The Wildcats lost 4-3 at Columbia in mid-May to close out a 29-4 campaign that included winning the final Pac-12 regular-season title and becoming the first non-California team to claim the conference tournament championship.

The UA also won a pair of matches at the ITA National Indoor Championship, knocking off a pair of ranked programs en route to having the highest ITA ranking (No. 5) in school history.

And on the individual front, junior Colton Smith reached the Division I semifinals, became the school’s first All-American since 2006 and qualified for the ATP Next Gen Accelerator program which will give him access to professional tournaments.

Smith is one of three returners from the singles rotation, along with Casper Christensen and Jay Friend. And the Wildcats are bringing in the No. 5 recruiting class in the country, per tennisrecruiting.net, highlighted by 5-star prospect Santiago Padilla Cote and Serbian Zoran Ludoski.

Clancy has had his contract extended multiple times, currently through 2028, but probably needs another raise to ensure he’s not poached.

What life in the Big 12 should look like

Fresh of conquering the Pac-12 in its final year of competition, Arizona now heads to a Big 12 Conference that features the reigning national champion. TCU beat soon-to-be-former Big 12 foe Texas in the NCAA Division I finals.

Baylor, Oklahoma State and UCF also made the NCAA Tournament this past season out of the Big 12, which will feature nine schools in 2025 with the addition of Arizona, ASU and Utah. BYU and Texas Tech are the other men’s tennis participants.

One big question

Is the Sweet 16 the ceiling? Arizona had never gotten out of the opening weekend of the NCAA tourney until 2021, but it’s now done that three times in four years. But each trip to the Sweet 16 has ended in defeat, and half of the 2024 team has graduated.

Getting to host the third round would be the next step in getting over that hump. All three of Arizona’s Sweet 16 appearances have been on the road, with this past season as the No. 9 seed.

Diamondbacks C Gabriel Moreno sprains thumb vs. Phillies


The Arizona Diamondbacks pulled starting catcher Gabriel Moreno in the bottom of the sixth inning of a 5-4 win at the Philadelphia Phillies on Friday due to a sprained left thumb.

The D-backs then removed left fielder Lourdes Gurriel Jr. in the eighth inning due to left elbow soreness, the team said.

Moreno was having a big day at the plate with a single and a two-run homer in three plate appearances. He blasted a Taijuan Walker sinker 433 feet in the third inning to take a 3-0 lead. The shot was the furthest homer of his big league career.

In the first inning, Moreno hit a liner to left field and tried to stretch it into a double, but he was thrown out at second. He attempted to dive around infielder Edmundo Sosa’s glove, which led to an awkward tag. It is unclear exactly when the injury occurred, but he grabbed at his thumb after getting tagged out.

Backup catcher Tucker Barnhart entered as a defensive replacement for Moreno to catch pitcher Jordan Montgomery.

Moreno and Barnhart are the only two catchers on the 26-man team, although the D-backs also have Jose Herrera on the 40-man roster. Hot-hitting prospect Adrian Del Castillo (1.014 OPS) is another option in Triple-A Reno.

Gurriel also homered off Walker on Friday and recorded a pair of hits. He struck out in the seventh inning and bent over after an off-balance swing. He remained in the game for an inning.

Randal Grichuk entered as his replacement.

D-backs broadcaster Jody Jackson reported postgame Moreno’s X-rays came back negative and Gurriel did not have X-rays taken.

Former Cardinals QB Gets Honest on Retirement Talk


ARIZONA — Former Arizona Cardinals quarterback Colt McCoy hasn’t taken an official snap since the 2022 season.

It might’ve been his last.

That’s not an easy truth to swallow for any football player, let alone a guy such as McCoy – who established himself as a Texas Longhorns legend before playing over ten years in the NFL.

McCoy suffered a neck injury and dealt with concussion symptoms towards the end of the 2022 season in Arizona. Leading into 2023’s training camp, he dealt with elbow issues that ultimately proved to be harsh enough for the Cardinals to cut him ahead of the regular season.

McCoy didn’t sign anywhere following his release from the desert and has been fairly hush on future plans – until recently.

Speaking with local reporters at his annual football camp in Austin, TX, McCoy got honest on his future with the sport.

“I haven’t really talked much about my situation – I never like to give excuses. I’ve been fortunate to play 14 years, I tore my elbow pretty bad and I’m not sure I’m gonna get over that, to be honest,” McCoy said.

“That’s a tough one. But at the same time, injuries are part of the game. I’ve certainly had my fair share and it’s almost kind of like a hard stop. So, we’ll see but [I] had many opportunities to jump back in last year week to week in a lot of places. I physically just wasn’t able to do it.”

McCoy has done a few guest appearances in the broadcast booth previously, and if he does indeed see the end of the tunnel of his playing career, McCoy says football will be in the mix regardless of what it is.

“I am a footballer for life and I want everybody to play football because I know what it’s done for me. So to have one chapter in and start another one, football will be a part of that somehow. Whether that’s coaching, whether that’s broadcasting, whether that’s talking football, whatever it is, it’s part of who I am,” McCoy said.

“I’m excited about more opportunities to come and what that is in life after this [who knows] but football is amazing.”
