Tucson Water: Notification of pipeline construction

Tucson Water recently submitted this release to the public regarding a portion of the new recycled water pipeline is scheduled to be installed beginning early June along Macarthur Street and Michigan Street.

The route goes from the I-19 frontage road on the west to Lundy Avenue on the east. It will then run on Lundy Avenue to Pennsylvania Drive. Below is information on how the construction of the pipeline will affect
that neighborhood area:

  • The section of roadway where pipeline construction is taking place will be closed during work hours to through traffic and signed “Local Traffic Only”. Crews will cover the trenches with steel plates at the end of each workday so you will be able to drive over the trenches.
  • Employees from the construction contractor PCL, will notify residents 2-3 days in advance of the trenching in front of your home and will make every effort to allow access when necessary. It will take 2-3 days for the construction activity to progress beyond your residence.
  • During construction hours, there will be open trenches in front of your homes. During these times we recommend that you park in an alley or along a section of street away from construction activity until the steel plates are placed back over the trench.
  • Construction crews will work Monday through Saturday, 7:00 a.m. – 6:00 p.m.
    Recycled water a valuable water resource for our community and is used to irrigate many of our community parks and schools, and using it helps to conserve our drinking water. Tucson Water appreciates your patience as we expand the recycled water distribution system to better utilize this water resource in our community.
  • Please contact Fernando Molina, Tucson Water, if you have any questions regarding this work. Molina can be reached at (520) 349-0982.

The Hill: Toxic chemicals also dangerous to our food

In an important report last year, The Hill brought light to how PFAS (poly- and perfluoroalkyl substances) are harmful to what we drink and eat.

PFAs are a class of chemicals used to add stain and water resistance to consumer products and some food packaging. They have also been widely used in firefighting foams.

According to the article, exposure to several PFAS increases the risk of some cancers, may interfere with children’s learning and development and is associated with increased cholesterol levels. PFAS have a distinctive carbon-fluorine bond that prevents them from readily breaking down, making them extraordinarily persistent once released in the environment and earning them the moniker of “forever chemicals.”

The article also states: “With rising levels of cancer and neurodevelopmental problems nationwide, we must act to protect our food supply from this widespread chemical contamination. We should all be able to enjoy summer ice cream and more without fear of PFAS contamination.”

UCAB Meeting Oct. 21

The quarterly Unified Community Advisory Board (UCAB) meeting will be a virtual event for UCABmembers only to be held on October 21 at 5:45 pm. Tucson Water will provide its quarterly update.

We will seek information of this meeting for those who are not UCAB members.

The meetings are usually held at the El Pueblo Senior Center every quarter of the year. The next meeting should be held in January or February.

The discussion for this quarter’s meeting will be about the No. 10 Well and its progress. There will also be updates from Tucson Water, the Tucson International Airport, Arizona National Guard and Air Force Plant 44.

KVOA Report: More Water Contamination Found in Tucson

On Sept. 21, KVOA reported: The City of Tucson is suing a company it says is responsible for toxic chemicals found in local wells. Now officials say they’re finding more contaminants.

“In the last several weeks we have found significant contamination of PFCs’ out by the Air National Guard. The EPA standard…Is 70 parts per trillion,” Tucson City Councilman Steve Kozachik said. “The contamination levels that we’re finding out by the Air National Guard are over 11,000 parts per trillion.”

Kozachik said the location of the contamination is immediately upstream of the central well field in midtown.

Epidemiological Studies Made Easy: Systematic Reviews, Meta-Analysis of Diseases

This video gives a simple overview of the most common types of epidemiological studies, their advantages and disadvantages. These include ecological, case-series, case control, cohort and interventional studies. It also looks at systematic reviews and meta-analysis that could include data gathering on people affected by water contamination.

Public Comment: Air Force Plant 44 Regional Groundwater Plume South of Los Reales Road

Part of the clean up selection process under the Superfund program involves the Air Force Plant 44 Regional Groundwater Plume, south of Los Reales Road.

The Air Force is proposing to conduct more clean up of hot spot areas where TCE and 1,4-dioxane (1,4-DX) levels are the highest.

The public can make a written comment on this hot spot treatment by e-mailing Air Force civil engineer George Warner at George.Warner@us.af.mil. Comments must be made by Sept. 30.

UA College of Engineering: $1.2 Million Grant Issued to Make Drinking Water Safer

A report in March from the University of Arizona College of Engineering revealed that the U.S. Department of Defense is funding a project that will allow a team of researchers led by chemical and environmental engineering professor Reyes Sierra to advance groundwater purification methods.

The report states: For decades, manmade chemicals known as per- and polyfluoroalkyl substances, or PFAS, were used in everything from carpets to frying pans to firefighting chemicals for their ability to repel water and oil. That was before a wide array of negative health effects ranging from cancer and low birth weights to effects on the immune system were discovered in some kinds of PFAS.
