Agent Orange, exposed: How U.S. chemical warfare in Vietnam unleashed a slow-moving disaster.
Some 45 million liters of the poisoned spray was Agent Orange, which contains the toxic compound dioxin. It has unleashed in Vietnam a slow-onset disaster whose devastating economic, health and ecological impacts that are still being felt today.
In the end, the military campaign was called Operation Ranch Hand, but it originally went by a more appropriately hellish appellation: Operation Hades. As part of this Vietnam War effort, from 1961 to 1971, the United States sprayed over 73 million liters of chemical agents on the country to strip away the vegetation that provided cover for Vietcong troops in “enemy territory.”
Using a variety of defoliants, the U.S. military also intentionally targeted cultivated land, destroying crops and disrupting rice production and distribution by the largely communist National Liberation Front, a party devoted to reunification of North and South Vietnam.
Some 45 million liters of the poisoned spray was Agent Orange, which contains the toxic compound dioxin. It has unleashed in Vietnam a slow-onset disaster whose devastating economic, health and ecological impacts that are still being felt today.
This is one of the greatest legacies of the country’s 20-year war, but is yet to be honestly confronted. Even Ken Burns and Lynn Novick seem to gloss over this contentious issue, both in their supposedly exhaustive “Vietnam War” documentary series and in subsequent interviews about the horrors of Vietnam.
Vietnam’s half-century of disaster
More than 10 years of U.S. chemical warfare in Vietnam exposed an estimated 2.1 to 4.8 million Vietnamese people to Agent Orange. More than 40 years on, the impact on their health has been staggering.
This dispersion of Agent Orange over a vast area of central and south Vietnam poisoned the soil, river systems, lakes and rice paddies of Vietnam, enabling toxic chemicals to enter the food chain.

Vietnamese people weren’t the only ones poisoned by Agent Orange. U.S. soldiers, unaware of the dangers, sometimes showered in the empty 55-gallon drums, used them to store food and repurposed them as barbecue pits.
Unlike the effects of another chemical weapon used in Vietnam – namely napalm, which caused painful death by burns or asphyxiation – Agent Orange exposure did not affect its victims immediately.
In the first generation, the impacts were mostly visible in high rates of various forms of cancer among both U.S. soldiers and Vietnam residents.
But then the children were born. It is estimated that, in total, tens of thousands of people have suffered serious birth defects – spina bifida, cerebral palsy, physical and intellectual disabilities and missing or deformed limbs. Because the effects of the chemical are passed from one generation to the next, Agent Orange is now debilitating its third and fourth generation.

A legacy of environmental devastation
During the 10-year campaign, U.S. aircraft targeted 4.5 million acres across 30 different provinces in the area below the 17th parallel and in the Mekong Delta, destroying inland hardwood forests and coastal mangrove swamps as they sprayed.
The most heavily exposed locations – among them Dong Nai, Binh Phuoc, Thua Thien Hue and Kontum – were sprayed multiple times. Toxic hotspots also remain at several former U.S. air force bases.
And while research in those areas is limited – an extensive 2003 study was canceled in 2005 due to a reported “lack of mutual understanding” between the U.S. and the Vietnamese governments – evidence suggests that the heavily polluted soil and water in these locations have yet to recover.
The dangerous quantity of residual dioxin in the earth thwarts the normal growth of crops and trees, while continuing to poison the food chain.
Vietnam’s natural defenses were also debilitated. Nearly 50 percent of the country’s mangroves, which protect shorelines from typhoons and tsunamis, were destroyed.
On a positive note, the Vietnamese government and both local and international organizations are making strides toward restoring this critical landscape. The U.S. and Vietnam are also undertaking a joint remediation program to deal with dioxin-contaminated soil and water.

The destruction of Vietnamese forests, however, has proven irreversible. The natural habitat of such rare species as tigers, elephants, bears and leopards were distorted, in many cases beyond repair.
In parts of central and southern Vietnam that were already exposed to environmental hazards such as frequent typhoons and flooding in low-lying areas and droughts and water scarcity in the highlands and Mekong Delta, herbicide spraying led to nutrient loss in the soil.
This, in turn, has caused erosion, compromising forests in 28 river basins. As a result, flooding has gotten worse in numerous watershed areas.
Some of these vulnerable areas also happen to be very poor and, these days, home to a large number of Agent Orange victims.
War propaganda and delayed justice
During Operation Ranch Hand, the U.S. and South Vietnamese governments spent considerable time and effort making the claim that tactical herbicides were safe for humans and the environment.
U.S. propaganda about Agent Orange was so effective, it fooled American troops into thinking it was safe, too.
It launched a public relations campaign included educational programs showing civilians happily applying herbicides to their skin and passing through defoliated areas without concern.
One prominent comic strip featured a character named Brother Nam who explained that “The only effect of defoliant is to kill trees and force leaves to whither, and normally does not cause harm to people, livestock, land, or the drinking water of our compatriots.”
Brother Nam assured readers that herbicides were safe. Wikimedia
It’s abundantly clear now that this is false. Allegedly, chemical manufacturers had informed the U.S. military that Agent Orange was toxic, but spraying went forward anyway.
Today, Agent Orange has become a contentious legal and political issue, both within Vietnam and internationally. From 2005 to 2015, more than 200,000 Vietnamese victims suffering from 17 diseases linked to cancers, diabetes and birth defects were eligible for limited compensation, via a government program.
U.S. companies, including Monsanto and Dow Chemical, have taken the position that the governments involved in the war are solely responsible for paying out damages to Agent Orange victims. In 2004, a Vietnamese group unsuccessfully attempted to sue some 30 companies, alleging that the use of chemical weapons constituted a war crime. The class action case was dismissed in 2005 by a district court in Brooklyn, New York.
Many American victims have had better luck, though, seeing successful multi-million-dollar class action settlements with manufacturers of the chemical, including Dow, in 1984 and 2012.
Meanwhile, the U.S. government recently allocated more than US$13 billion to fund expanded Agent Orange-related health services in America. No such plan is in store in Vietnam.
It is unlikely that the U.S. will admit liability for the horrors Agent Orange unleashed in Vietnam. To do so would set an unwelcome precedent: Despite official denials, the U.S. and its allies, including Israel, have been accused of using chemical weapons in conflicts in Gaza, Iraq and Syria.
As a result, nobody is officially accountable for the suffering of Vietnamese victims of Agent Orange. The Burns and Novick documentary could have finally raised this uncomfortable truth, but, alas, the directors missed their chance.

EPA removes waste at Texas toxic sites, won’t say from where.
The Environmental Protection Agency says it has recovered 517 containers of “unidentified, potentially hazardous material” from highly contaminated toxic waste sites in Texas that flooded last month during Hurricane Harvey.
By Michael Biesecker | AP September 23 at 10:44 PM
WASHINGTON — The Environmental Protection Agency says it has recovered 517 containers of “unidentified, potentially hazardous material” from highly contaminated toxic waste sites in Texas that flooded last month during Hurricane Harvey.
The agency has not provided details about which Superfund sites the material came from, why the contaminants at issue have not been identified and whether there’s a threat to human health.
The one-sentence disclosure about the 517 containers was made Friday night deep within a media release from the Federal Emergency Management Agency summarizing the government’s response to the devastating storm.
At least a dozen Superfund sites in and around Houston were flooded in the days after Harvey’s record-shattering rains stopped. Associated Press journalists surveyed seven of the flooded sites by boat, vehicle and on foot. The EPA said at the time that its personnel had been unable to reach the sites, though they surveyed the locations using aerial photos.
The Associated Press reported Monday that a government hotline also received calls about three spills at the U.S. Oil Recovery Superfund site, a former petroleum waste processing plant outside Houston contaminated with a dangerous brew of cancer-causing chemicals. Records obtained by the AP showed workers at the site reported spills of unknown materials in unknown amounts.
Local pollution control officials photographed three large tanks used to store potentially hazardous waste completely underwater on Aug. 29. The EPA later said there was no evidence that nearby Vince Bayou had been impacted.
PRP Group, the company formed to clean up the U.S. Oil Recovery site, said it does not know how much material leaked from the tanks, soaking into the soil or flowing into the bayou. As part of the post-storm cleanup, workers have vacuumed up 63 truckloads of potentially contaminated storm water, totaling about 315,000 gallons.
It was not immediately clear whether those truckloads accounted for any of the 517 containers cited in the FEMA media release on Friday. The EPA has not responded to questions from AP about activities at U.S. Oil Recovery for more than a week.
About a dozen miles east, the San Jacinto River Waste Pits Superfund site is on and around a low-lying island that was the site of a paper mill in the 1960s, leaving behind dangerous levels of dioxins and other long-lasting toxins linked to birth defects and cancer. The site was completely covered with floodwaters when the AP surveyed it on Sept. 1.
To prevent contaminated soil and sediments from being washed down river, about 16 acres of the site was covered in 2011 with an “armored cap” of fabric and rock. The cap was reportedly designed to last for up to 100 years, but it has required extensive repairs on at least six occasions in recent years, with large sections becoming displaced or having been washed away.
The EPA has not responded to repeated inquiries over the past two weeks about whether its assessment has determined whether the cap was similarly damaged during Harvey.
The companies responsible for cleaning up the site, Waste Management Inc. and International Paper, have said there were “a small number of areas where the current layer of armored cap is thinner than required.”
“There was no evidence of a release from any of these areas,” the companies said, adding that sediments there were sampled last week.
The EPA has not yet released those test results to the public.

Move over malaria: Mosquitoes carrying Zika, dengue may thrive in warmer Africa.
Hotter weather and migration to cities may make different diseases the scourge of the future in Africa, scientists say.
by Kieran Guilbert | KieranG77
DAKAR, Sept 22 (Thomson Reuters Foundation) - From deadly droughts and destroyed crops to shrinking water sources, communities across sub-Saharan Africa are struggling to withstand the onslaught of global record-breaking temperatures.
But the dangers do not end there. Rising heat poses another threat - one that is far less known and studied but could spark disease epidemics across the continent, scientists say.
Mosquitoes are the menace, and the risk goes beyond malaria.
The Aedes aegypti mosquito, which spreads debilitating and potentially deadly viruses, from Zika and dengue to chikungunya, thrives in warmer climates than its malaria-carrying cousin, known as Anopheles, say researchers at Stanford University.
In sub-Saharan Africa, this means malaria rates could rise in cooler areas as they heat up, but fall in hotter places that now battle the disease. In those areas, malaria - one of the continent's biggest killers - may be rivalled by other vector-borne diseases as major health crises.
"As temperatures go past 25 degrees Celsius (77 degrees Fahrenheit), you move away from the peak transmission window for malaria, and towards that of diseases such as dengue," said Erin Mordecai, an assistant professor at Stanford.
"We have this intriguing prospect of the threat of malaria declining in Africa, while Zika, dengue and chikungunya become more of a danger," she told the Thomson Reuters Foundation.
Besides a warming planet, scientists fear growing urbanisation across Africa could also fuel the transmission of diseases carried by the Aedes aegypti mosquito, which flourishes in cities and slums - the opposite of the country-loving Anopheles.
One in two Africans are expected to live in cities by 2030, up from 36 percent in 2010, according to World Bank data.
A soaring number may become prey to vector-borne viruses like dengue, which have struck Africa at a record pace in recent years, fuelled by urbanisation, population growth, poor sanitation and global warming, the World Health Organization (WHO) says.
"We see poorly planned development in Africa, not just with megacities but smaller settlements ... which often lack proper water and sanitation," said Marianne Comparet, director of the International Society for Neglected Tropical Diseases.
"Climate change, disease and the interaction between man and habitat - it is a crisis going under the radar ... a time-bomb for public health problems," she added.
NEGLECTED DISEASES
Last year was the hottest on record, for the third year in a row, with global temperature rise edging nearer a ceiling set by some 200 nations for limiting global warming, according to the European Union's climate change service.
Parts of Africa were among the regions suffering from unusual heat.
As temperatures keep rising, mosquitoes in low-latitude regions in East African countries are finding new habitats in higher altitude areas, yet malaria rates are falling in warmer regions, such as northern Senegal in the Sahel, studies show.
So as cooler parts of sub-Saharan Africa gear up for the spread of malaria, hotter areas should prepare for future epidemics like chikungunya and dengue, experts say.
While not as lethal as malaria, chikungunya lasts longer and can lead to people developing long-term joint pain. Dengue causes flu-like symptoms and can develop into a deadly hemorrhagic fever.
There is a danger that the global drive to end malaria, which absorbed $2.9 billion in international investment in 2015, has left African countries ill-prepared to deal with other vector-borne diseases, said Larry Slutsker of the international health organisation PATH.
"Diseases such as dengue and chikungunya have been neglected and under-funded," said Slutsker, the leader of PATH's malaria and neglected tropical diseases programmes. "There needs to be much better surveillance and understanding."
Malaria kills around 430,000 people a year, about 90 percent of them young African children.
Dengue, the world's fastest-spreading tropical disease, infects about 390 million annually but is often badly recorded and misdiagnosed, health experts say.
Some experts believe the global alarm triggered by Zika, which can cause birth defects such as small brain size, may see more money pumped into fighting neglected tropical diseases in sub-Saharan Africa, especially after outbreaks in Angola, Cape Verde and Guinea-Bissau during the last year.
Although 26 African nations - almost half of the continent - have strategies in place to fight vector-borne diseases, most of them only target malaria, according to data from the WHO.
Malaria rates have been slashed in recent decades through the use of bed nets, indoor spraying and drugs. But there are no dedicated treatments or vaccines for chikungunya and dengue.
"The most important preventive and control intervention is vector management, particularly through community engagement," said Magaran Bagayoko, a team leader for the WHO in Africa.
DISENTANGLING DATA
However, efforts to beat back mosquitoes are hampered by a lack of quality and affordable climate data that could help predict outbreaks and indicate risks, said Madeleine Thomson of the International Research Institute for Climate and Society.
"What countries really want to know is what they can do to improve their programmes, as well as the capacity of their health workers," said the scientist at the Columbia University-based institute.
But to do that, "climate information must be put into practice", Thomson added.
African nations also must improve coordination between their health ministries and meteorological agencies, said the Africa Centers for Disease Control and Prevention (Africa CDC), a new continent-wide public health agency launched this year by the African Union.
"They are not linked, or talking to each other," said Sheila Shawa, a project officer at the Africa CDC headquarters in Ethiopia. "There needs to be better communication in order to model neglected diseases, such as chikungunya, across Africa."
Yet climate scientists and health experts warn of the difficulty of analysing the impact of rising temperature on mosquito-borne diseases without looking at other factors.
"We have a major challenge of isolating effects of rising temperatures – which are really variable – from all the other aspects like rainfall patterns, humidity, mobility and migration, as well as socioeconomic factors," said Stanford's Mordecai.
"They are all changing at the same time, making individual drivers very difficult to isolate and disentangle for analysis."

Diseases of poverty identified in Alabama county burdened by poor sanitation.
Study finds “shocking” incidence of parasite infections in Lowndes County.
By Brett Walton, Circle of Blue
In the poorest sections of the American South researchers are finding hookworm, dengue fever, and other parasites and viruses that are more commonly associated with developing countries or, in the United States, with the early years of the 20th century.
The latest evidence comes from Lowndes County, Alabama, where Baylor College of Medicine researchers went on an expedition for parasitic worms. They found that two in five people who participated in a recently published health study had intestinal parasites, primarily hookworm. The parasite, once considered contained, is making a comeback in the Black Belt, a region of clay soil that stretches across nearly two dozen counties in central Alabama.
“I was shocked, quite shocked,” Rojelio Mejia, the Baylor College of Medicine researcher who guided the study, told Circle of Blue. “We thought hookworm was eradicated, or at least under control. To find such a high prevalence was concerning.”
Surprised at the results, the research team double- and triple-checked the data to verify accuracy. The peer-reviewed study was published online on September 5 in the American Journal of Tropical Medicine and Hygiene. The diseases, the researchers said, are now less a matter of political borders and more a function of economics and sanitary conditions. In this health equation, the poor suffer.
Though the study’s numbers are startling, the high incidence of parasitic infections is more understandable due to conditions on the ground, Mejia said. The central Alabama climate — warm and humid — is favorable for worms to flourish. Because hookworm is not a sensational disease like Zika or Ebola, it attracts less attention, he said. Anemia and lethargy are common symptoms, rather than birth defects or death. Perhaps most important — and most galling — is that many people live in unsanitary surroundings.
The Alabama Center for Rural Enterprise, a local nonprofit that has conducted surveys to collect data, estimates that half of the homes in Lowndes County have failing septic systems or no sanitary sewage disposal at all. According to U.S. Census Bureau data, more than one-third of households in the county are in poverty.
Many homes in the county are too scattered for a central wastewater facility, and septic systems are often a poor fit for the dense Black Belt soils, which do not drain well enough to filter waste. There are high-tech septic systems on the market, but the cost — around $10,000 to $12,000 — could consume most of a poor household’s annual income. An unknown number of homes instead connect their toilets and sinks to “straight pipes” that send the waste into gullies, creeks, or backyard pits. In these conditions, hookworm and other parasites can thrive.
More than a century ago, in 1909, John D. Rockefeller Sr. gave $1 million to establish the Rockefeller Sanitary Commission, an initiative with the goal of eradicating hookworm in the South. The commission’s work, however, lasted only five years, and hookworm continued to fester in certain areas. Infection rates in high-risk Alabama counties in the 1950s were as high as 60 percent.
Then hookworm assessments largely ceased. Health researchers stopped looking for it. Mejia said the most recent study he could find that included field research was a 1993 graduate student paper that was not published in an academic journal. The study found one to two percent of participants had hookworm in Wilcox County, a Black Belt neighbor of Lowndes.
The Wilcox study and Mejia’s study are difficult to compare. What changed is the method of investigation. Older studies assessed hookworm infections by looking at stool samples beneath a microscope. The level of magnification provided by the lens is not strong enough to detect parasites below a concentration of roughly 12 eggs per gram.
Mejia instead used DNA analysis, which is sensitive to low parasite concentrations, even below one egg per gram. Better equipment means an increase in detection, he said.
Sixty-six people, all African Americans, participated in the study, which included samples of blood, stool, and soil as well as a health questionnaire. Stool samples, taken from 55 of the participants, showed that 23 had a parasite, 19 of which were hookworm.
The number of people in the study was smaller than Mejia had hoped, largely because of the difficulty in recruiting volunteers. There is widespread mistrust within the communities of outside researchers because straight pipes are illegal. Authorities can fine residents, jail them, or even take custody of children living in such conditions.
“People are afraid,” Catherine Flowers, executive director of the Alabama Center for Rural Enterprise, told Circle of Blue. She assisted Mejia, who said that without Flowers the study would probably not have been possible.
Sanitation Failures Widespread in Alabama
No person has done more than Flowers to shine a light on sewage failures in rural Alabama. In November 2012, after reading his New York Times op-ed about tropical diseases spreading among the poor in the southern United States, Flowers sent an email to Peter Hotez, dean of the National School of Tropical Medicine at Baylor College of Medicine.
Hotez had estimated that at least 12 million Americans, mostly in the states bordering the Gulf of Mexico, were living with diseases caused by worms and bacteria commonly associated with the warm, humid countries of the tropics: afflictions such as dengue fever, Chagas disease, and parasitic infections that cause seizes.
“They are the forgotten diseases of forgotten people,” Hotez wrote in the piece, published on August 18, 2012.
Flowers, though, would not let the rest of America forget. A week after sending the email, she traveled to Atlanta to meet Hotez, who was attending the annual meeting of the American Society of Tropical Medicine and Hygiene, and explain the problems in Lowndes County. A year earlier she had testified before the United Nations’ independent expert on drinking water and sanitation. More recently, in June, she gave a tour to Sen. Corey Booker, a Democrat from New Jersey, who was traveling in Alabama, Mississippi, and Louisiana to learn about the links between poverty, race, health, and the environment in the South.
Failing septic systems and the use of straight pipes are not confined to Lowndes County, but the extent of the problem is largely unknown. According to Mark Elliot, a University of Alabama researcher, there have been only two rigorous, county-level studies in the United States to establish how many households have failing septic systems or straight pipe discharge. Both studies are more than a decade old.
The first, in 2000, was conducted in Madison County, North Carolina. It found 5.6 percent of homes had straight pipes. The other study, based on data from Bibb County, Alabama, in 2006, found 15 percent of homes used a straight pipe and 35 percent had failing septic systems. In Bibb County alone this discharge corresponds to more than 60,000 gallons of raw sewage per day along with billions of enteric viruses, giardia, and cryptosporidium.
A smaller survey in 2016 of 289 homes without sewer connections in Wilcox County, Alabama, found at least 60 percent with straight pipes, which Elliot called “a staggeringly high number.” Wilcox County is poorer than Bibb County, and poverty is an indicator of straight pipe use. Based on that survey, Elliot estimates that 550,000 gallons of raw sewage in the county enters the Alabama River watershed every day. That figure assumes that each person generates 100 gallons of wastewater a day through showering, toilet flushing, and washing clothes and dishes, which is probably an overestimate of the daily discharge.
Straight pipes are probably more common than thought. An Auburn University study in 2011 estimated that half of Alabama’s Black Belt is unsuitable for septic systems because of poorly drained soils.
Because of the region’s clay soils, wastewater does not readily soak into the ground. Heavy rains can then flush the sewage into creeks and rivers. Elliot tested this by sampling water from Big Prairie Creek, in Hale County, during the 2016 drought and immediately after the first big rain that fall. Water samples downstream of the town of Newbern saw a huge jump in E. coli after the rain — concentrations increased by 1,000 times compared to the drought period. In Newbern, according to best estimates, at least half of homes use a straight pipe.
Elliot does not blame the county health departments, which, he says, have no good options. The arrest, in 1999, of people in Lowndes with illegal sewage disposal provoked backlash and, besides, health departments have no handy solution to offer, he explained. “People really don’t have an option,” he told Circle of Blue.
Mejia and his colleagues hope to eliminate ignorance of the problem. With the results of the initial study now published, Mejia said that he will apply for funding for a larger investigation: a health study of several hundred, maybe even 1,000 people in the county. Then researchers can begin to map areas of greatest need.
Mejia also says there is more work to do on the connections between climate change and disease. Hookworm larvae hibernate in cold temperatures. If winters are warmer, then the window for contracting the parasite, which enters the body through the skin, opens wider.
Flowers, for her part, pins hopes on developing a low-cost wastewater treatment system that suits Black Belt soils.
“We need to deal with the places that haven’t had infrastructure that functions,” she said.

Peter Dykstra and host Steve Curwood discuss two contradictory science-related Trump administration nominees as well as developments on the Zika Virus, this week in Beyond the Headlines. They also note the devastating Great Galveston Hurricane that hit Texas in 1900.
Transcript
CURWOOD: Let’s check on the world beyond the headlines now with Peter Dykstra of DailyClimate.org and Environmental Health News, EHN.org. Peter is on the line from Atlanta, Georgia. Hey there, how are you doing?
DYKSTRA: Doing all right, Steve. Hi.
Let’s start with mixed messages from the Trump Administration on how it’s planning to address pressing environmental concerns.
CURWOOD: Well, a lot of environmental advocates would tell you that a mixed message is the best messaging they’ve heard in a while from this administration.
DYKSTRA: Yeah, that’s probably true, but President Trump took two different directions on two key appointments dealing with climate change and climate policy. Jim Bridenstine is an avid pilot and he’s the congressman for Tulsa, Oklahoma. He’s Trump’s belated pick to run NASA, one of several key home agencies for US Government climate science.
CURWOOD: Hmm, I seem to remember a previous member of the Oklahoma delegation from Tulsa who was also an avid pilot and who had a pretty strong profile on climate change.

DYKSTRA: And he still does, and of course you’re referring to the Senate’s uber-climate denier, Jim Inhofe, who’s called climate change “a hoax”. Bridenstine’s something of a protégé of Senator Inhofe.
CURWOOD: Well, presumably not good news for the state of Federal climate science.
DYKSTRA: No it’s not, but over at NOAA, the number two slot is going to an actual scientist with an actual background in oceanography and an actual track record of concern about what the science says climate change is doing right now.
CURWOOD: Well, how did that happen?
DYKSTRA: Another mystery, but retired Rear Admiral Tim Gallaudet will be poised to swim against the tide of climate denial espoused by the President, espoused by several cabinet members, and by quite a few Senators like Jim Inhofe who will be called upon to approve his appointment.
CURWOOD: So, another policy head-scratcher. What’s next?
DYKSTRA: Well, one of the fierce new stresses of 2016, thought to be here to stay, has pretty much been AWOL for the year 2017. Do you remember Zika?
CURWOOD: Oh, yeah, the widespread mosquito-borne disease that caused so many birth defects a year ago.
DYKSTRA: Well, in 2017, I’m happy to report that it’s pretty much stopped. Cases in South America and the Caribbean are way down, and the Florida Department of Health has received one-tenth the number of new case reports than they did a year ago.
CURWOOD: Well that’s good news, but is there a reason for this decline?
DYKSTRA: We don’t know what the reason is, but let’s take the good news where we can get it, whether it’s in Florida and Latin America, even if there’s good news with a bad news component.
CURWOOD: Uh-oh, I thought there’d be a catch. What’s the bad news?
DYKSTRA: The vaccine-making giant Sanofi Pasteur has been working on a Zika vaccine, but its partners at the US Food and Drug Administration lost interest and dramatically cut funding, so no more vaccine project. It would have been nice to have a vaccine, if Zika should make a comeback.
CURWOOD: Agreed. Hey, Peter, finally, let's crack open the history books for this week.
DYKSTRA: Sure, and let’s set the way-back machine for the year 1900. The Great Galveston Hurricane of September 8, 1900 could make a pretty good claim to being the storm of the century. Galveston, just 50 miles southeast of Houston, had already blossomed into a major vacation spot on the Gulf of Mexico, and it was also a major shipping town to export cotton and the other goods of the great state of Texas. In 1900 the US Weather Bureau was only thirty years old, and forecasting models didn't have computers, or satellites, or even wireless warnings from ships at sea.
CURWOOD: So, we had no warning that a huge storm was bearing down on Galveston?
DYKSTRA: Well, that’s the thing. Actually we did, but political rivalries got in the way. The storm had already done a huge amount of damage in Cuba. Then it gathered strength across the warm waters of the Gulf of Mexico, and Cuban meteorologists tried to warn their American counterparts, but the American weathermen and the Cubans hated each other’s’ guts, so the Cuban warnings went largely ignored.

CURWOOD: And more than, what, 6,000 people perished?
DYKSTRA: At least 6,000. But you know, today, with modern forecasting and instant communications and the painful lessons of Galveston and other disasters, the death tolls for comparably fierce storms in a bad hurricane year, like the one we’re in now, is way down from the Storm of the Century of the year 1900.
CURWOOD: Peter Dykstra is with Environmental Health News – that’s EHN.org – and DailyClimate.org. Thanks, Peter, we’ll talk to you again real soon!
DYKSTRA: All right, Steve, thanks a lot. Talk to you soon.
CURWOOD: And there’s more on these stories at our website, LOE.org.

After Noah survived the great deluge, God placed a rainbow in the sky as an everlasting covenant with man, promising to never again punish the Earth with such a deadly flood.
Any rainbow sheen you may see today across the Gulf Coast floodwaters is no godly doing. Runoff from chemical plants, petroleum pipelines and at least a dozen Superfund sites risks transforming the destructive rain into a putrid stew filled with lead, arsenic and other toxic and carcinogenic chemicals.
So you can't help but worry when looking at the pictures of the Vita Bella assisted-living center during Hurricane Harvey - an elderly woman calmly knitting in the Dickinson nursing home while the brown waters swirl around her feet.
They could have used an ark.
The image was shocking enough to hasten a rescue, but the damage may have already been done. After all, some of the worst flood hazards can't be picked up by photograph.
"There's no need to test it. It's contaminated. There's millions of contaminants," Porfirio Villarreal, a spokesman for the city of Houston Health Department told the New York Times as to the floodwaters.
Nowhere is the risk more worrisome than the San Jacinto waste pits, which sit between the communities of Highlands and Channelview. One of the San Jacinto waste pits, covered by a temporary armored cap, was partially submerged in the river even before Hurricane Harvey. Now they're totally engulfed.
Last year, the Army Corps of Engineers predicted the protective device might not be reliable "under very extreme hydrologic events which could erode a sizable portion of the cap."
Harvey - which has been called a 1,000-year-flood - would certainly qualify. Now we have to worry that the cap was damaged and the toxic mess has spread downriver to Galveston Bay.
As part of the recovery efforts, Environmental Protection Agency Administrator Scott Pruitt should make time to visit the submerged pits, which were designated a federal Superfund site in 2008.
Pruitt has said he plans to create a "top-10 list" of key Superfund sites and target sites where "the risk of human exposure is not fully controlled."
The pits fit the bill: They've been ravaged by weather and contain dioxin, a highly toxic chemical that increases the risk for several cancers, including lung cancer and non-Hodgkin's lymphoma, and has been linked to birth defects, liver damage and dermatological disorders.
The EPA actually proposed a solution to the pits last year: Remove about 202,000 cubic yards of contaminated material at cost of nearly $100 million. Of course, the cost and nature of the remediation may have changed depending on whether the armored cap has been damaged.
Regardless, Pruitt should cut through the bureaucratic red tape that has slowed the cleanup of this site and act boldly in holding companies responsible for past contamination.
This site has been unsafe for over 60 years - longer than many Texans have been alive. It is time to finally clean up our river. Any Harvey recovery bill must fund this sort of ecological repair alongside the economic and infrastructure needs.
"For years our communities and local government have told the EPA it is not a matter of if, but when, a storm devastates the pits," Jackie Young, executive director of the Texas Health and Environment Alliance, told the editorial board.

Closure of US coal study marks an alarming precedent.
The Trump administration has stepped up its assault on environmental protections by halting a US$1-million study on the health risks of coal mining — casting a pall on academic freedom.

US President Donald Trump makes his priorities clear during a rally in West Virginia.
When the US National Academies of Science, Engineering, and Medicine (NASEM) speaks, the government usually listens. Last year, US government agencies spent US$216 million to commission NASEM expertise on issues from the scientific workforce to military implications of synthetic biology. Most NASEM reports are filled with caveats and make for dry reading. But occasionally, they pull no punches. A memorable 2009 report on the state of forensic science, for instance, concluded that almost every forensic method used in law enforcement is seriously flawed and that their use risks putting innocent people in jail. Given the academies’ stature, it’s hard for the government to brush off its hired commission when faced with such language.
Such concerns seem to weigh on the US Department of the Interior (DOI), which in 2016 commissioned a $1-million study of the potential health risks of surface coal mining on communities in West Virginia. Some evidence suggests that people who live near surface-mining operations — also known as mountaintop removal — have an unusually high rate of lung cancer and birth defects, which could be attributed to air and water pollution.
Launching the study — now halfway through its two-year term — was itself an achievement, given the political nature of the topic. Although much is known about the risks of coal mining to miners, little research has been done on its health impacts on local communities, not least because of attempts by the coal industry to hinder such work. Mining companies and trade organizations have sued for access to the e-mails of academics researching mountaintop removal, and have fought to keep peer-reviewed studies from being used in court. The National Mining Association questioned the value of the NASEM study when it was announced.
On 18 August, three days before the NASEM committee working on the study was due to meet in a Kentucky mining town, the DOI ordered a stop to the study, with immediate effect. The agency says it is reviewing spending on all projects that cost more than $100,000. “The Trump administration is dedicated to responsibly using taxpayer dollars in a way that advances the department’s mission and fulfils the roles mandated by Congress,” DOI spokeswoman Heather Swift said in a statement to Nature. She did not respond to questions about which other projects are under review.
This is the first time that the administration of President Donald Trump has cancelled a NASEM study that has already started — a move that has rarely happened in the past, according to the academies.
In its statement about the cancellation, the NASEM said that its investigators “stand ready” to resume as soon as the DOI completes its review. But they’re likely to be waiting a long time. The Trump administration has made no secret of its fondness for the US coal industry, which employs around 76,000 people. (By comparison, around 1.2 million people live in counties where mountaintop removal takes place.) The DOI’s assertion that the decision is a budgetary one is suspect, especially given that the study has already spent a good amount of its budget.
It seems, instead, that the government would rather quash the review than risk it producing results that cast aspersions on the coal industry. This is par for the course for the DOI, whose head, Ryan Zinke, plans to downsize national parks in favour of resource extraction, and which has also suspended meetings with its independent advisory councils on issues concerning public lands.
With the near-daily news about the Trump administration weakening climate and environmental protections, it is easy to become fatigued. Yet the move to pre-empt the prestigious and independent NASEM is particularly concerning. It raises questions about what other studies could be cancelled if the government fears their results. It is another blow for science and for academic freedom.
