The Hopkins Robotics Cup, hosted by the Center for Educational Outreach at Johns Hopkins University’s Whiting School of Engineering, has been rescheduled from January 30 on the JHU Homewood campus to Saturday, Feb. 6 at Highlandtown Elementary/Middle School, due to the recent winter weather.

The event is a competition open to all Baltimore City Public Schools with VEX Robotics teams. The game for 2016, Nothing But Net, challenges teams to build robots designed to score points by launching balls into nets with various target zones.

Marc Edwards, the Charles P. Lunsford Professor in the Department of Civil & Environmental Engineering at Virginia Tech, will deliver the Charles and Mary O’Melia Lecture in Environmental Science at 3 p.m. on Tuesday, Sept. 20 in 110 Hodson Hall.

The title of Edwards’ lecture will be “The Washington D.C. Lead Crisis (2001-2004): Prelude to Flint 2015.”


The 2001-2004 Washington D.C. lead in drinking water crisis (and its aftermath to the present day) is a unique case study in the history of engineering and scientific misconduct. The multi-year exposure of an unsuspecting population to very high levels of the best-known neurotoxin, was perpetrated by multiple government agencies whose mission was to protect the public health. These same agencies later published falsified research reports, covering up evidence of harm and justifying ill-conceived interventions wasting hundreds of millions of dollars and which created even more harm. Aspiring to uphold the duty of scientists and engineers to hold paramount the public good and welfare, Marc Edwards worked alongside collaborators in the public, press and in Congress for over a decade. Their efforts exposed some of the wrong-doing by the agencies and their “hired gun” consultants, who brazenly twisted science to obfuscate the truth of what occurred. These experiences raise concerns about the veracity of “research” conducted and funded by government agencies, especially in crisis situations when public harm has occurred, as well as the need for checks and balances on agency power. Due to our inability to learn from and admit our mistakes, a similar crisis such as that which occurred in Flint, MI, 2014-present, was inevitable.

This event will be live streamed on the Johns Hopkins University Facebook page.

  • Marc Edwards is the Charles Lunsford Professor of civil engineering at Virginia Tech, where he teaches courses in environmental engineering, applied aquatic chemistry and engineering ethics. His research group aspires to pursue science as a public good, through laboratory work on practically important but underfunded topics such as corrosion in buildings and opportunistic premise-plumbing pathogens—that work laid the groundwork for investigative science uncovering the 2001-2004 D.C. Lead Crisis and the 2014-2016 Flint Water Disaster.

    Time Magazine dubbed Edwards “The Plumbing Professor” in 2004, and listed him amongst the 4 most important “Innovators” in water from around the world. The White House awarded him a Presidential Faculty Fellowship in 1996. In 1994, 1995, 2005, 2011 and 2016 Edwards received Outstanding Paper Awards in the Journal of American Waterworks Association and he received the H.P. Eddy Medal in 1990. His M.S. Thesis and PhD Dissertation won national awards from the American Water Works Association (AWWA), the Association of Environmental Engineering and Science Professors (AEESP) and the Water Environment Federation. He was later awarded the Walter Huber Research Prize from the American Society of Civil Engineers (2003), State of Virginia Outstanding Faculty Award (2006), a MacArthur Fellowship (2008-2012), and the Praxis Award in Professional Ethics from Villanova University (2010). His paper on lead poisoning of children in Washington D.C., due to elevated lead in drinking water, was judged the outstanding science paper in Environmental Science and Technology in 2010. In 2013 Edwards’ was the 9th recipient (in a quarter century) of the IEEE Barus Award for “courageously defending the public interest at great personal risk,” and in 2016 he was named amongst the most influential people in the world by Fortune and Time magazine.


May 3 @ 5:30 pm – 7:30 pm

Come see students present their hands-on STEM projects, explore STEM through interactive demonstrations, and learn more about STEM in the community at the 2017 SABES STEM Showcase.

The goal of STEM Showcases is to bring the community together around STEM by providing accessible opportunities for hands-on STEM engagement. STEM Showcases offer a forum for students to share their STEM projects with each other, their families and their community. During STEM Showcases, students showcase the projects that they have been working on during the school day or afterschool program. Interactive demonstrations are also offered by community partners, such as the Maryland Science Center, National Aquarium, Maryland Zoo, and the Baltimore Museum of Industry, to provide families and community members an opportunity to explore and learn together.

RSVP is required to attend. Click here to RSVP.

How to Survive when Resources are Scarce: Colorful Bacterial Strategies

While much is known about the adolescent phase of bacterial growth, very little is understood about what sustains bacteria once they reach middle/old age. Interestingly, it is at this later stage that many bacteria begin to produce colorful, redox-active pigments—compounds that hitherto have been classified as “secondary” metabolites, or “antibiotics.” A sizable fraction of bacteria in the environment are metabolically quiescent—viable, but not actively growing. This is true whether they are attached to electrodes in marine sediments, plant roots, or surfaces in the human body. Newman will discuss how her research suggests that the production of pigmented antibiotics may actually be essential for sustaining life at this late phase of microbial development—a discovery with potentially wide-ranging applications, from providing new strategies to boost the efficiency of microbial fuel cells to identifying new therapeutic targets in the context of infection.

Re-Envisioning Wastewater Treatment for the 21st Century

Abstract: The philosophy of municipal wastewater treatment has changed only slowly in the past 100 years. From approximately 1920 to 1970, a wastewater discharge was considered acceptable if the dissolved oxygen level in the receiving stream did not dip below 5 mg/L downstream of the discharge. Protecting aquatic life, particularly fish, from immediate death due to low oxygen levels was the primary motivation and the goal. The passage of the Clean Water Act in 1970 reflected a broader view to include concerns about eutrophication by nutrients and ecological and human health concerns with the naming of “priority pollutants.” Nevertheless, the central concept was that discharge concentrations would be acceptable if they took advantage of the assimilative capacity of receiving waters; that is, if they limited the harm to acceptable values. Now we are embarking on a new philosophy, captured by the phrase “One Water” by the Water Environment Federation, in which we think of wastewater not as a problem for disposal but as a resource.

Why is this shift in philosophy happening? At least two major changes have occurred since the old philosophies were developed. First, a dramatically increased population has led to a substantial increase in “indirect potable reuse” of wastewater, whereby the effluent discharge from one city is a part of the drinking water source for a downstream city. In many areas of the arid Southwest, that “part” can often be nearly 100%. An extension of this trend, due to water shortages, is the drive toward direct potable reuse of wastewater. Second, not only do the chemical and pharmaceutical industries now produce tens of thousands of synthetic chemicals that were not dreamed of when the “priority pollutant” list associated with the Clean Water Act was developed, we now understand that some of these products are endocrine disruptors and others lead to microbial antibiotic resistance.

In this talk, I will try to make the case that wastewater treatment needs to be changed, perhaps radically, to reflect the new philosophy and to meet the needs of the 21st century. The thrust of the presentation will be to explore some possibilities for these radical changes and try to back them up with preliminary engineering calculations.
