Marc Edwards (born 1964) is a civil engineering/environmental engineer and the Charles Edward Via Professor of Civil and Environmental Engineering at Virginia Tech. [1] An expert on water treatment and corrosion, Edwards's research on elevated lead levels in Washington, DC's municipal water supply gained national attention, changed the city's recommendations on water use in homes with lead service pipes, and caused the Centers for Disease Control and Prevention to admit to publishing a report so rife with errors that a congressional investigation called it "scientifically indefensible." He is considered one of the world's leading experts in water corrosion in home plumbing, [2] and a nationally recognized expert on copper corrosion. [3] He is also one of the whistleblowers in the Flint water crisis, along with Dr. Mona Hanna-Attisha.

Contents

Edwards was named a MacArthur Fellow in 2007. [4] The program cited him for "playing a vital role in ensuring the safety of drinking water and in exposing deteriorating water-delivery infrastructure in America’s largest cities." [4] In 2004, Time magazine featured him as one of the United States' most innovative scientists. [5]

Biography

Edwards, a native of the Buffalo, New York area, received a Bachelor of Science degree in biophysics from the State University of New York at Buffalo in 1986. [2] [4] He received his Master of Science in 1988 and his Ph.D. in engineering in 1991 from the University of Washington. [2] [4]

Edwards taught at the University of Colorado at Boulder. [4] In 1997, he joined the faculty of Virginia Tech's department of civil and environmental engineering. [2] From 2001 to 2005, he served as president of the board of directors for the Association of Environmental Engineering and Science Professors. [6] He delivered Virginia Tech's Graduate School Commencement address on December 19, 2008. [7]

He lives with his wife Jui-Ling and two children Ethan and Ailene in Blacksburg, Virginia. [2]

(2003 - 2010) Lead levels in Washington, DC water supply

Edwards's research in the mid-1990s focused on an increasing incidence of pinhole leaks in copper water pipes. Homeowners contacted him about the leaks, some of which were occurring 18 months after installation. [2] After a century of using copper for water pipes, the expectation is that they will last for 50 years in residential applications. [2] The District of Columbia Water and Sewer Authority (WASA) funded Edwards's research into the cause of the leaks. [8]

A group of Washington, DC homeowners asked Edwards to investigate their corroding copper pipes in March 2003. Suspecting the water, he tested for lead. The accepted limit for lead in drinking water is 15  parts per billion (ppb). Edwards's meter, which could read values up to 140 ppb, showed off-the-scale readings even after he had diluted the sample to ten percent of its original strength. [2] The water contained at least 1,250 ppb of lead. [5] "Some of it would literally have to be classified as a hazardous waste," he said. [2] At the time, WASA recommended that customers in areas served by lead pipes allow the water to run for 30 seconds to one minute as a precaution. [2] Edwards's tests showed that the highest lead levels occurred 30 seconds to a few minutes after the tap was opened. [2]

When Edwards brought his concerns to WASA, the agency threatened to withhold future monitoring data and research funding from him unless he stopped working with the homeowners. [2] The Environmental Protection Agency (EPA) discontinued its subcontract with him. [2] With his funding cut off, Edwards paid his engineering students out of his own pocket so that they could continue the research. [2]

After the Washington Post ran front-page stories in January 2004 about the problem, a Congressional hearing was held in March 2004 where Edwards testified. [2] [9] At the hearing, Edwards identified the cause of the readings as monochloramine, a disinfecting chemical that had replaced chlorine in the water supply in March 2000. [2] Chloramine-treated water, he said, picks up lead from pipes and solder and does not release it, resulting in elevated levels. [8] Chloramine also doesn't break down over time, as chlorine does, so there is always some in the water system. [10] Edwards also testified that WASA's attempts to replace lead pipes with copper pipes could exacerbate the problem, because the copper increases corrosion of the old lead. [9]

Following the discontinuation of chloramine treatment in 2004, Edwards and his colleagues continued to study the long-term effects of the elevated water lead levels; [11] their article "Elevated Blood Lead in Young Children Due to Lead-Contaminated Drinking Water," published in the journal Environmental Science and Technology, won that publication's Editor's Choice Award for the best science paper of 2009. [12]

Referring to a study by the Centers for Disease Control and Prevention (CDC) that essentially dismissed the idea of health risks from DC's lead-contaminated water, Edwards wrote to James Stephens, the CDC's associate director of science: "Why is it that every child I have personal knowledge of, who had a strong chance of having elevated blood lead from water, is either deleted or otherwise misrepresented in the data that CDC has and used for this publication?" [13] Edwards did not receive a response until March 2008, when Stephens wrote "We have examined CDC's role in the study and have found no evidence of misconduct." [13]

As a result of Edwards's research, the United States House of Representatives' science and technology subcommittee conducted a congressional investigation into the matter. They concluded that the CDC made "scientifically indefensible" claims that the lead levels in DC were not harmful, knowingly using flawed data. [14] In the wake of the investigation, Edwards called for the CDC paper's senior author to resign. [14] The day after the House report was released, the CDC released a public statement admitting to their errors. [15] James Elder, former national director of groundwater and drinking water for the EPA, said "Had Edwards not gotten involved, this would never have come out." [15]

In 2010, the CDC said that 15,000 homes in the DC area might still have water supplies with dangerous levels of lead. [16] Following Edwards's recommendation, the DC water authority now warns homeowners with lead water-supply lines to let the tap run for ten minutes before drinking or cooking. [5]

During his work on the Washington water quality, said Bill Knocke, head of Virginia Tech's civil and environmental engineering department, Edwards was so concerned about the public health impact that he was hospitalized due to the stress. [17]

(2004-2014) Notable Projects

In 2006, Edwards suggested that the EPA testing procedure for lead in tap water could miss elevated levels because it called for homeowners to remove the aerator from their faucet before drawing water for testing. The screen in the aerator, he said, could trap lead particles; if so, water drawn for testing would not reflect the full lead exposure experienced by people drinking from the faucet under normal use. [18]

In 2007, the University of North Carolina at Chapel Hill hired Edwards to investigate water-quality problems in three buildings. (When UNC asked its engineering faculty for guidance, their response was "We have two words for you—Marc Edwards.") [19] He found "low-grade and fixable" lead contamination, which he blamed on "lead-free" brass plumbing fixtures. [20] According to Edwards, Federal regulations permit up to 8 percent lead in "lead-free" brass fixtures, which can leach from the fixtures if the water is corrosive. [20] He says that the Federal standard uses a water formulation that is remarkably tame compared to actual water supplies, allowing such fixtures to pass lead-leaching tests. [19] Edwards provided a solution to UNC's problem: Accelerate the leaching of the lead by running each faucet at full flow for ten minutes, and then leaving it open at a trickle for three days, after which most of the lead had leached out. [19]

In a 2008 radio interview, Edwards noted that the United States has over five million lead water pipes, many of which are nearing the end of their useful life. [21] "In some cases, you can take a single glass of water," he said, "and if you're unlucky, and it has that piece of lead in it, you can get a very high dose of lead, similar to that which you could obtain by eating lead paint chips." [21]

During the Society of Environmental Journalists' 2008 annual meeting, the group was given a tour of Edwards's lab. He told them that the number one cause of waterborne disease outbreaks in the United States is pathogens growing in home water heaters. [22] Energy-conscious households may set their water heater's thermostat to 120 °F (49 °C), but that temperature encourages the growth of microbes such as mycobacteria. [22] A setting of 140 °F (60 °C) would kill such organisms. [22] Edwards says that infections from inhaling steam from contaminated water in the shower, or contact with contaminated water in a hot tub, kill an estimated 3,000 to 12,000 Americans each year. [22]

Responding to a 2009 Associated Press investigation of contaminants found in the drinking water of schools across the United States, Edwards was quoted as saying "If a landlord doesn't tell a tenant about lead paint in an apartment, he can go to jail. But we have no system to make people follow the rules to keep school children safe?" [23]

Edwards has also warned about the unintended effects of state-of-the-art water conservation techniques being used in new buildings. Systems such as rainwater capture and water recycling, he says, may reduce the flow of water from the city's system so much that the water remains in the plumbing for as much as three weeks before use. [24] This can cause the water to pick up lead and grow bacteria. [24] He has called for a more holistic approach to water quality monitoring. [24]

In 2011, the Robert Wood Johnson Foundation's Public Health Law Research Program funded a $450,000 study of the 1991 Lead and Copper Rule, an EPA regulation relating to drinking water. Edwards will spearhead the study. [25]

(2015 - present) Flint water crisis

In September, 2015, after receiving a call from Flint, Michigan citizen, LeeAnne Walters, Edwards formed a water study team and traveled to Flint, Michigan to perform a study that uncovered high levels of lead in potable water. The city's water source had been switched from the Detroit water system to the Flint River in 2014, exposing over 100,000 people to high lead levels and affecting up to 12,000 people with lead poisoning. [26] [27] [28]

Edwards' initiative inspired Mona Hanna-Attisha, a Flint public health advocate and pediatrician, to perform her own study on Flint’s children that found that the lead levels in their blood increased as a result of the water source switch. [29] Edwards and Hanna-Attisha's results caused the City of Flint, the State of Michigan and the United States to declare a state of emergency. [30]

In early 2016, Edwards testified twice before the United States House Committee on Oversight and Government Reform on the crisis, [31] [32] and was appointed to Michigan Governor Rick Snyder's Flint Water Interagency Coordinating Committee, to alleviate problems related to the water crisis. [33]

In 2016, Edwards gave an interview to The Chronicle of Higher Education arguing for scientists to work in the public interest. [34]

In July 2018, Edwards filed a $3 million defamation lawsuit against Flint mother Melissa Mays and two other activists Paul Schwartz and Yanna Lambrinidou. The lawsuit came in the wake of the Flintcomplaints.com letter, signed by over 60 Flint residents, expressing certain grievances with Edwards. On March 19, 2019, the case was dismissed by Judge Michael F. Urbanski, the Chief Judge for the Western District of Virginia, ruling that Edwards could not use litigation to silence criticism and advance scientific claims. The ruling noted, "the Flint water crisis is a paradigmatic example of a matter of public concern where the freedom to call for an ‘investigation’ into the activities of those in positions of significant persuasive power and influence is essential.” [35]

On November 7, 2019, Edwards was interviewed on Detroit's NPR station, WDET in Season 2 of the station's podcast series titled, "Created Equal," which focused on the people involved with the Flint Water Crisis. [36]

(2019 - present) Notable projects

In 2019, Edwards headed a Virginia Tech research team to investigate elevated salt levels in water wells on 100 farms in Fishers Landing, NY. [37]

A corrosion inhibitor or anti-corrosive is a chemical compound added to a liquid or gas to decrease the corrosion rate of a metal that comes into contact with the fluid. The effectiveness of a corrosion inhibitor depends on fluid composition and dynamics. Corrosion inhibitors are common in industry, and also found in over-the-counter products, typically in spray form in combination with a lubricant and sometimes a penetrating oil. They may be added to water to prevent leaching of lead or copper from pipes.

<span class="mw-page-title-main">Flint water crisis</span> Contamination by lead of water supply in Flint, Michigan

The Flint water crisis was a public health crisis that started in 2014 after the drinking water for the city of Flint, Michigan was contaminated with lead and possibly Legionella bacteria. In April 2014, during a financial crisis, state-appointed emergency manager Darnell Earley changed Flint's water source from the Detroit Water and Sewerage Department to the Flint River. Residents complained about the taste, smell, and appearance of the water. Officials failed to apply corrosion inhibitors to the water, which resulted in lead from aging pipes leaching into the water supply, exposing around 100,000 residents to elevated lead levels. A pair of scientific studies confirmed that lead contamination was present in the water supply. The city switched back to the Detroit water system on October 16, 2015. It later signed a 30-year contract with the new Great Lakes Water Authority (GLWA) on November 22, 2017.

The Pittsburgh water crisis arose from a substantial increase in the lead concentration of the city's water supply. Although catalyzed by the hiring of cost-cutting water consultancy Veolia in 2012, and an unauthorized change of anti-erosion chemicals in 2014, this spike in lead concentration has roots in decades of lead pipe erosion. Since the Pittsburgh Water and Sewer Authority (PWSA) first failed its water quality test in 2016, it has exceeded the federal lead threshold of 15 ppb by almost 1.5 times. This level of lead contamination poses serious health risks to residents, particularly children and pregnant women. In an attempt to remedy the situation, the PWSA has begun removing lead pipes from the city's water lines and has decided to introduce orthophosphate to the water supply.
