Drinking Water Shouldn’t Reek of Chlorine

  When appropriately applied, chlorine added to drinking water should not result in any type of odor reminiscent of a pool party. When chlorine can be smelled in water, there are exceedingly high levels of toxic chemical compounds reacting together. Typically, drinking water comes from natural sources such as lakes, rivers, and streams. It can also be recycled in water treatment plants throughout cities to remove leaves, dirt, fish, and other organic waste. One of the primary treatment methods used to remove the organic matter is chlorine, which is super-effective at killing harmful organisms (bacteria, parasites, viruses, etc.) Cholera, dysentery, and chronic diarrhea outbreaks were common before water chlorination treatment. Unfortunately, using chlorine to disinfect water isn’t foolproof. The amount of chlorine needed for water disinfection varies and teeters on a thin line between too much and not enough. If the water smells like chlorine, the water utility in charge of ...

Michigan Creates Drinking Water Panel

 The Michigan Department of Environment, Great Lakes, and Energy (EGLE) recently created a Corrosion Control Advisory Panel aimed at drinking water remediation. EGLE also implemented new standards earlier in the year, including the Lead and Copper Rule (LCR), which helps detect lead in drinking water. There are seven drinking water professionals on the Corrosion Control Advisory Panel: -           Elin Betanzo, PE, president and founder, Safe Water Engineering, LLC -           David Cornwell, CEO, Cornwell Engineering Group, Inc. -           Darren Lytle, environmental engineer, U.S. Environmental Protection Agency (EPA) Drinking Water Management Branch CESER Water Infrastructure Division -           Susan Masten, professor, Department of Civil and Environmental Engineering, Michigan State Un...

Ozone Proves to be Useful to Disinfect Water

  The standards of water disinfection are currently chlorine and ultraviolet light when pertaining to city water. A project called MIKROOZON backed by Schleswig-Holstein, CONDIAS, and the European Union aims to create a tiny ozone generator for people to use in water dispensers or appliances such as fridges or dishwashers. There are several advantages when it comes to ozone being used for water disinfection, including a positive environmental impact, a short retention time, and tasteless quality. Ozone is an excellent choice when it comes to combatting germs, thanks to its high oxidation potential. The cell membrane in common pathogens is easily broken down by ozone. Ozone water disinfection is the standard in Germany to clean swimming pools, drinking water, and wastewater. However, ozone is not typically implemented to purify water in small appliances such as ice machines, water dispensers, and showers. Norman Laske, a researcher at Fraunhofer ISIT, said, "The ozone gene...

Signs of Dehydration

  Water is an essential aspect of our lives; we drink, bathe, cleanse, and use water daily. The chemistry of life is based on water; over 60 percent of the human body is made up of water. In the human body, water is necessary for vital functions, including: -           Manufacturing hormones -           Creating saliva -           Keeping mucus membranes moist -           Allowing the body’s cells to grow and reproduce -           Regulating body temperature -           Acting as a shock absorber for the spinal cord and brain -           Flushing body waste -           Maintaining a sufficient electrolyte bala...

Distrust of Tap Water Results

  Throughout the United States, an increasing number of Americans show signs of distrust in tap water. About 60 million did not drink their tap water in 2018, according to a study published by Pennsylvania State University researchers. This marked a 40 percent increase when compared to 2014. The drinking water crisis that emerged in Flint prompted the rise in consumers questioning tap water purity. Despite assurances that the water was safe, scientists proved them wrong by conducting independent tests showing astonishingly high lead levels. Though the water crisis in Flint was broadly publicized, other cities have struggled with lead in their water systems as well. Washington, DC, Chicago, Newark, Toledo, Ohio, and Charleston, West Virginia, have all been publicly grappling with drinking water emergencies. Erik Olson, senior director of the National Resources Defense Council, said, “The fundamental problem with drinking water is that we continue to live off the investments o...

How Labs Are Working to Identify PFAS

  Per- and polyfluoroalkyl chemicals ( PFAS ) are prominent environmental toxins found in countless products ranging from non-stick cookware, waterproof materials, cleaning products, fabrics, packaging, furniture, firefighting foam, and more. Thanks to its prevalence in industrial manufacturing, PFAS has infiltrated the global food chain and water supply. Studies have shown that more than 99 percent of the American population holds PFAS in their bloodstream. PFAS is known to cause various health issues , including cancer, liver issues, heightened cholesterol, lower infant birth weight, kidney disease, and much more. While PFAS use is being diminished in commercial and manufacturing methods, these toxins are still widely used. Moreover, they do not break down through time, so those produced in the 20 th century can still be found in our environment. There are new types of PFAS popping up frequently as industry sectors develop various products. Soil and water supply are perfe...

EPA Grants 1.2M to U-M to Study Wastewater Viruses

  The United States Environmental Protection Agency (EPA) has granted the University of Michigan researchers $1.2 million. The purpose of the funds is to study the efficiency of current wastewater virus removal treatments. One of the overall goals is to increase the viability of using wastewater as drinking water. While existing technologies might be quite effective, they can be equally complex. By upgrading the water treatment facilities – particularly in drought-prone areas – reusing wastewater might be more realistic and practical. Krista Wigginton, associate professor of civil and environmental engineering, said, “In areas where water scarcity is becoming a growing concern, they may be forced to look at methods like desalination or potable reuse for their drinking water. If we make reuse rules too stringent, and we’re not giving treatment systems the proper credit for what they’re already removing from the water, we’re going to create a much more expensive project for comm...
