Antibiotic Resistant Bacteria and Genes in Wastewater and Drinking Water

We’ve written about antibiotic (antimicrobial) resistance and “superbugs” several times in recent years, and based on what we continue to learn, there is likely more to come. Antibiotics are used widely in animal agriculture and aquaculture and are also found in wastewater. These pharmaceuticals are excreted by animals and people who are taking antibiotics and when unused pills and liquids are flushed down the toilet or poured into the drain. All of these actions result in antibiotics entering the water environment and our wastewater systems, and have contributed to antibiotic resistant bacteria known as ARB. I wrote in 2015 that “Responsible use and disposal of antibiotics will go a long
way toward reducing the unintended consequences of their entering the waste stream.”


Chlorinated Tap Water: Benefits and Risks

It’s hard to believe that an article I wrote almost a decade ago, Chlorine in Tap Water Is Safe to Drink, remains the most popular of our now over 350 perspectives by the Water Quality & Health Council (WQ&HC). An update seemed in order, but based on its long-established (over 110 years) efficacy and safety: chlorinated tap water is still safe to drink.


Highlighting Drinking Water Week 2019

Next week, May 5–11, is the American Water Works Association’s (AWWA) Drinking Water Week—a time when water professionals and the communities they serve join together to recognize the essential public health role of safe drinking water. With just the turn of a tap, most Americans have unlimited access to safe, high quality, and inexpensive (pennies


Hot Tap Water Quality: Q&A with Emily Fritz of Louisville Water Company

Every day, Americans consume more than one billion glasses of tap water, the majority of which is provided by over 50,000 community water systems. Conventional water treatment transforms raw water into safe (finished) drinking water for pennies per gallon, thanks to widespread treatment, disinfection, and protection of water as it travels to your home. The


Celebrating World Water Day 2019: Water for All

As we have done for the past several years, the WQ&HC highlights the United Nations’ (UN) World Water Day, which is held annually on March 22nd and affirms the importance of safe water in our lives. This year’s theme, “Water for All: Leaving No One Behind” is fundamentally tied to the UN Sustainable Development Goal 6 (SDG 6), “Ensure availability and sustainable management of water and sanitation for all” by 2030.


Drinking Water Challenges in a Winter Wonderland

As much of America endures a particularly cold winter—especially for those of us in the polar vortex-targeted tundra of northern Minnesota—our aging drinking water infrastructure is under tremendous pressure. Cold temperatures, snow, and ice can challenge large metropolitan water treatment facilities and privately-owned household wells alike. Fortunately, there are many proactive steps that experienced public water system operators, as well as savvy homeowners, can take each year before temperatures fall to help ensure that safe drinking water is available during even the coldest winter. That way, everyone can focus more on enjoying the wintry weather (and ice fishing) and less on responding to water-related crises.


Are Drinking Water and Ice on U.S. Airlines Safe?

Flying while thirsty? Every year, millions of Americans travel on thousands of commercial airplanes visiting friends and family, taking well-deserved vacations, or conducting business. While many travelers are concerned about their checked baggage arriving, chances are few think about the quality and safety of the drinking water or ice on their flight. But according to


Drinking Water Quality Challenges in Canada’s First Nations

Almost 1.7 million people, or 4.9% of the Canadian population, identify themselves as a member of one of Canada’s three distinct groups of Indigenous peoples and cultures—Inuit, First Nations, and Métis. Of these, the over 630 First Nation communities are the largest and comprise more than 50 distinct nations and languages. Management of drinking water quality for the First Nations is typically shared between individual communities and the Government of Canada. On reserves, Chiefs and Councils manage the day-to-day operations, including testing drinking water and issuing drinking water advisories. Indigenous Services Canada (ISC) provides funding for First Nation water facility design and construction, operations and maintenance, and training and certifying operators. ISC also advises and supports drinking water quality monitoring programs.


The State of Lead Testing in School Drinking Water

Although lead has been banned in U.S. drinking water infrastructure since 1986, it is still present in older lead-soldered copper and cast iron lines serving schools and other buildings. Lead can also be present in some indoor plumbing, solder, and fixtures at older schools, including high-lead brass faucets and in some drinking water fountains. Since


Cyber Security 101 for Drinking Water

As we move closer to another new decade in the not-so-new millennium, it seems a safe bet that virtually everyone reading this article is familiar with cyber security. By now, many readers have been personally affected by a breach in cyber security. Despite being celebrated as a U.S. public health triumph, drinking water utilities are
