Another ‘Forever Chemical’ Called 1,4 Dioxane Found in Ann Arbor

 

Popular in the second half of the 20th century, 1,4-dioxane was used in pharmaceutical ingredients, filters, metal degreasers, and more. In toxicity studies, laboratory rodents given the chemical in their drinking water developed liver cancer. The United States National Toxicology Program classifies 1,4,-dioxane as a human carcinogen. The United States Environmental Protection Agency also deemed the synthetic chemical a likely carcinogen.

In the United States, production of 1,4-dioxane has diminished, though certain companies import it from Germany to supply customers. Even as the use of 1,4 dioxane declines, the chemical is not disappearing. Water monitoring data collected from 2010 to 2015 shows that more than seven million people in the United States in 27 different states had utility-supplied tap water with detectible levels of 1,4-dioxane according to the Environmental Working Group (EWG).

There is currently no federal limit on 1,4 dioxane in drinking water, and removing it is challenging. When released into the air, the chemical poses a cancer risk. However, it doesn’t float through the air often or evaporate easily. It dissolves completely in water, even at high concentrations, making it difficult to remove.

Traditional groundwater treatments filter water through granulated activated carbon to remove chlorine and other contaminants. This technology is not applicable to 1,4-dioxane. Many communities have water tainted with worrisome levels of 1,4-dioxane. After leaking out of landfills or as a result of unregulated industrial practices, 1,4-dioxane may infiltrate public aquifers.

In Ann Arbor, between 1966 and 1986, 1,4-dioxane was filtered into groundwater through lagoons that held wastewater from the manufacture of medical and industrial filtration equipment at Gelman Sciences, which has since closed. There is currently litigation regarding the underground plume of 1,4-dioxane headed for the Huron River, Ann Arbor’s main source of drinking water.

Cleaning products, laundry detergents, and shampoos still contain 1,4-dioxane as an unintentional impurity from surfactants, typically rinsed down the drain.

Michigan Announces $267 Million in Grants to Enhance Water Infrastructure

  Michigan's EGLE has announced a significant investment of $267 million through the MI Clean Water grants to revamp the state’s water infrastructure. This funding aims to bolster dozens of local governments and water systems, enhancing public health and environmental protection. Key projects include new storm sewers and green infrastructure in Oakland County, lead water service line replacements in Marquette, and water main upgrades in South Haven. Governor Gretchen Whitmer emphasized the commitment to ensuring every resident has access to clean, safe water and highlighted the extensive measures taken to replace lead pipes and enhance sewer systems to mitigate flooding. This latest grant initiative extends across Michigan, impacting communities from the rural Upper Peninsula to urban centers in the lower state. The MI Clean Water Plan is set to address both legacy and emerging water system challenges, such as aging infrastructure and contaminants like PFAS. Supported by fu...

Benefits of a Having a Water Softener System Installed in your Home

Water is said to be hard when the high quantity of minerals such as dissolved calcium and magnesium are present. Having a water softener system installed in your home can prove to be beneficial in more than one way. A water softener is especially useful in areas where all people have access to is hard water.  Before shedding light on the benefits of having a water softener system installed in your home, let’s first look at some of the negative consequences that come with having hard water.

Protect Yourself from PFAS ‘Forever Chemicals’

  Per- and polyfluoroalkyl fluorinated substances called PFAS are dubbed “Forever Chemicals” due to the chemical bonds that hold the compounds together (about 5,000 substances) which never break down in the environment. PFAS can be found everywhere; they are in hundreds of products such as food-delivery containers and papers, nonstick cookware, stain-resistant clothing, carpets, and furniture, fireproof items, clothes, cosmetics, personal care products, and so much more. Tiny doses of PFAS are linked to cancer, reproductive and immune system damage, weight gain, and a plethora of other diseases. It is estimated that PFAS are found in the blood of 99.9 percent of all human beings on Earth, including newborn babies. For many reasons (including factory and facility discharge), PFAS have been found in drinking water throughout the United States. Over 1,400 communities in 49 states have detected PFAS in their drinking water according to the Environmental Working Group (EWG). This eq...
