WATER: Rivers and Rights

Colorado River, Horseshoe Bend in Arizona,” by photographer Charles Wang, 2023. Creative Commons 4.0. Included with appreciation.

Colorado River Basin states are working together to agree upon water use and rights. Source of drinking water for 40 million people (7 U.S. states, Mexico, and 30 Tribes of original Americans), the Colorado River has recently seen lower levels of water. Drought has plagued the area, with prospects for recharge by melting seasonal snowpack now questioned by warming related to climate change.

In 2026, present agreements on water allocation among stakeholders will expire. Rather than wait for political change, Colorado River Compact states are drafting their own new regulations. Working with the Bureau of Reclamation, agency in charge of administering the Compact, states will submit their draft plan by March 2024.

Water use restrictions are expected. Water recycling will be important: many communities are developing systems for reuse. Southern Nevada Water Authority announced that water may not be used on “non-functional turf’ – that means lawns. It was the first permanent regulation on lawns and grass: the new law will take effect in January 2027.

Whanganui River of New Zealand was granted legal personhood rights. Will other rivers follow suit? Image: “Whanganui River” by photographer Felix Engelhardt, 2009. Creative Commons 2.0. Included with appreciation.

Another option? Legal personhood for important bodies of water. In New Zealand, the Whanganui River was granted legal personhood. In India, the Ganges, of sacred importance, and the Yamuna, River of the Taj Mahal, applied for legal personhood status. In the United States, the City of Toledo, Ohio sought legal rights status for Toledo’s Lake Erie harbor. Could the Colorado River seek such rights, protecting and securing its ability to recharge and renew?

Water laws have progressed through three stages. Image: 123 numbers gif. Public Domain, CC0. Included with appreciation.

In the past century, water laws have progressed through three stages. Early laws established rights to use water. Next, with environmental awareness, laws addressed rights of water itself to health, renewal, and sustainability. Now, with climate change, laws have begun to concern access in times of drought and water scarcity.

WATER/SPACE: New Year’s Eve Invitation

“New Year’s Eve” celebration by videographer Cemp, 2019. Creative commons 3.0. Included with appreciation.

New Year’s Eve is often celebrated by popping a cork, releasing bubbles of hope for health and happiness. This year, cork your name into a bottle, sending your greetings and wishes into the future. Who knows who might pop the cork?

Europa, one of Jupiter’s moons, is a watery world that may support life. Image: European Space Agency (ESA) Hubble, 2016. Included with appreciation.

NASA‘s Europa Clipper spacecraft, traveling 1.8 billion miles (2.6 billion kilometers), will visit Europa, a moon of Jupiter. Evidence reveals a water world there that may support life. Arriving on the shore, in a very high-tech bottle, could be your name and a message.

“A bottle containing a sheet of music that has washed up on shore.” Image: snapwire, 2017. Dedicated by the photographer to the public domain. Included with appreciation.

This message will be from one water world to another. Ada Limón, U.S. Poet Laureate, whose “In Praise of Mystery: A Poem for Europa” will grace the gift, has written this poem:

In Praise of Mystery: A Poem for Europa by Ada Limón

Arching under the night sky inky

with black expansiveness, we point

to the planets we know, we

pin quick wishes on stars. From earth,

we read the sky as if it is an unerring book

of the universe, expert and evident.

Still, there are mysteries below our sky:

the whale song, the songbird singing

its call in the bough of a wind-shaken tree.

We are creatures of constant awe,

curious at beauty, at leaf and blossom,

at grief and pleasure, sun and shadow.

And it is not darkness that unites us,

not the cold distance of space, but

the offering of water, each drop of rain,

each rivulet, each pulse, each vein,

O second moon, we, too, are made

of water, of vast and beckoning seas.

We, too, are made of wonders, of great

and ordinary loves, of small invisible worlds,

of a need to call out through the dark.

You can listen to the poem, read by Ada Limón, here.

VOICE OF THE FUTURE 2023: AI

“AI-generated virtual movie star Ornella Muti” by Lasemainecomtoiise, 2018. Creative Commons CC0. Public domain. Included with appreciation.

Is it live or is it AI? The year 2023 saw breakthroughs in Artificial Intelligence (AI), accelerated by ChatGPT and other wonders. Legal questions emerged, marking the recognition of a significant milestone in civilization. Sam Altman, co-founder of OpenAI, made the news.

Legal issues on the rights of AI began in 2019 when the Device for the Autonomous Bootstrapping of Unified Sentience (DABUS) was named as inventor-of-record in a U.S. patent application. But DABUS was developed by a human, Stephen Thaler. Deliberations resulted in the decision that AI is not a person, and patents can be awarded only to those with personhood. In 2022, Thaler appealed; but the Federal Circuit Court issued an opinion on 5 August 2022 that “the invented cannot be the inventor.” (Nemec 2023) What would Alan Turing say?

Many credit Alan Turing as one of the early founders of computer science and artificial intelligence. Image: “Alan Turning” circa 1930. Public Domain. Included with appreciation.

In 2023, the Thaler decision led the U.S. Patent Office to express interest in additional guidance on how to handle AI’s contribution to inventions. It’s a question for our times, and for the future. AI not only walks the walk; it talks the talk.

AI has a voice. We hear it in chatbots, and we challenge it in strikes like that of the Writers Guild of America (WGA) and Authors Guild in 2023. AI-generated texts are a worry not only for authors whose carefully crafted language may be providing free training for bots who will later generate texts, but also for professors who must now consider plagiarism in a new way. Copyright law is also expanding to set guidelines for AI.

Did you know that AI is racking up medical and pharmaceutical innovations? AI-driven drug discovery is being carried out by more than 250  companies, half of which are in the United States. The advantage of AI as a research partner is speed: Sumitomo Dainippon Pharma and Exscientia developed DSP-1191 to ease a difficult condition in one-quarter of the normal time it takes for such discoveries. (McKinsey, 2022)

While much of the activity, and controversy, concerning AI stirs the American economy, the European Union may be the first to develop AI laws. The 2023 EU’s “AI Act” forbids AI that threatens public safety and person’s rights. The law developed over two years of discussion, noting chatbots, OpenAI, ChatGPT, image-generation technologies, as well as audio and video. AI images have mesmerized and influenced over 100 million users. Images may include facial recognition, important to law enforcement and immigration, but also perhaps threatening to personal privacy and frequently racially unjust.

Facial recognition software is a form of AI. Image: “Eigenfaces from ORL face data” from AT&T Laboratories, Cambridge. Public Domain. Included with appreciation to AT&T and ORL.

EU and US law both address use of the prompt to generate images through AI. Such images are, by definition, not applicable to copyright law because they do not contain enough material that can be judged as created by a human. Artists, including members of creative communities like HUG, are taking note. Here’s such an image:

ENERGY: (Re)Vision for Coal

Coal-fired power plants, repurposed, may offer great innovation opportunities. Image: “Coal burning” by Diddi4, 2017. Creative Commons CC0. Included with appreciation.

Many are terming COP28 as the “beginning of the end.” While the desired wording of “phasing out” degraded into “transitioning,” still it was the first time directly naming and targeting “fossil fuels in energy systems.”

Of the three primary fossil fuels (coal, oil, natural gas), coal is the most polluting. And it is also very expensive to mine: digging enormous holes in the ground, hauling up heavy materials, crushing, washing, transporting coal to plants that themselves are both expensive to run and in need of repair, replacement, or retirement. More than 80% of U.S. coal plants cost more to keep running than to replace with new forms of energy generation. Regulations will accelerate closings: the 2028 laws concerning protecting drinking water from coal ash and other toxins may make compliance prohibitively costly. Duke Energy announced intention to close 11 coal-fired power facilities earlier than expected, at the same time declaring a move to renewable energy investment.  Georgia Power stated it would close all of its 14 coal plants (by 2035) while pivoting to solar and wind. Peabody Coal, largest private company in the coal business in the world, recently announced investment in solar and storage. (Marcacci, 2022).

Coal is the most polluting of the fossil fuels. Image: “Close up of smoke from coal stack” by John L. Alexandrowicz, 1975, National Archives and Records Administration, USA. Public Domain Creative Commons CC0. Included with appreciation.

Even if soon becoming obsolete in their original purpose, repurposed coal plants offer a valuable asset: they are already wired to the grid. That’s why repurposing rather than decommissioning coal-fired power plants may be a great opportunity. And, it should be noted that repurposing plants will keep jobs, taxes, and revenues in the community. Here’s two examples of advantageous repurposing of coal-fired power plants.

Brayton Point went from coal to wind. Image: “Aerial view of Brayton Point Power Station,” circa 1990, from Massachusetts Department of Environmental Protection. CC2.0. Included with appreciation.

Brayton Point Power Station was once the biggest coal-fired power plant in New England, generating 1600 MW of electrical power for more than half a century. In 2017, the plant closed. One year later, Commercial Development Company, Inc., (CDC) bought what was left and started the process of clean-up, needed demolition, site re-grading, and preparing for a new vision. With 300 acres (121 hectares) on a spacious waterfront with a 34-feet (10 meters) deep water port, the site was advantageous. Brayton Point offered access to the powerful winds of the Atlantic Ocean. When partner Prysmian Group signed on to acquire 47 acres for construction of a subsea cable manufacturing facility, coal-to-wind transition was born with a planned energy capacity of 30GW. Partner Mayflower Wind will also take a role, bringing 1,200 MW to Brayton Point from its wind farms 30 miles (48 kilometers) off island Martha’s Vineyard and 20 miles (32 kilometers) off Nantucket. Brayton Point will serve as a valuable nexus for wind energy because it has legacy grid connections. A National Grid substation will bring power to one million homes. Further benefits are construction jobs (325) and area revenues ($250 million). More opportunities will open for tenants on the newly designed site.

Space Solar Power, wirelessly beamed to Earth, could use retired, repurposed coal-fired power plants as receiving and transmission stations. There are over 8,000 on the planet – offering an instant global distribution network. Caltech demonstrated success in 2023. Image: “Solar Power Satellite Concept” by NASA, 2011. Public domain image included with appreciation.

A powerful possibility is using former coal-fired power plants as land stations to receive and transmit space solar power. In 1971, visionary Peter E. Glaser filed US patent application US00165893A for “Method and apparatus for converting solar radiation to electrical power.” NASA started work on Glaser’s idea, but at the time space technology was not developed sufficiently to realize the potential.  In 2023, the dream became vision with demonstrated proof. Caltech’s Space Solar Power Project (SSPP) and its Microwave Array for Power-transfer Low-orbit Experiment (MAPLE) sent a space solar power prototype into orbit, and wirelessly transmitted to a receiver on Earth – March 3, 2023 was the exact moment. The success was designed by a Caltech team led by Bren Professor of Electrical Engineering and Medical Engineering, co-director of SSPP, Ali Hajimiri. It was with the help of Donald Bren, chair of Irvine Company. Bren had read an article in Popular Science as a young person and never forgot the concept. A series of donations launched the Caltech project. Northrop Grumman also donated. It might be noted that when space-based wireless power arrives on earth, the energy source may need receiving stations. Rather than build a whole new network, repurposed coal-fired plants, already connected to the grid, might stand at the ready to realize a new power system. With over 8,000 coal-fired power plants already in place, coal-fired power plants may be the ideal, already-built, global network for reception and distribution of space solar power.

WATER: Sparkle Season Innovations

“Menorah” by Nagamani J., 2019. Creative commons 4.0. Included with appreciation.

T’is the season. Menorah lights glow. Christmas decorations shine. Kwanzaa candles illumine. Festive cards with sparkles greet celebrants who themselves don bedecked apparel. But did you know that glitter and sparkle usually gleam with plastic coatings? Sparkle – greeting cards and packaging, holiday ornaments, festive dresses and party attire – may be made from chemicals that are toxic and largely unregulated. It’s an area of plastic pollution that we rarely consider.

“Christmas baubles.” by KamrynsMom, 2008. Creative commons 3.0. Included with appreciation.

Hang an ornament on a holiday tree – it may glow in the lights but later sprinkle some coating dust. A child may open a card shining with glitter, and later wash their hands before enjoying holiday treats. Sparkle left on little fingertips may wash down the drain and into the water supply. Teens can twirl to holiday party music but their festive attire might shed a sequin or two. Dance floors are swept, and mops are rinsed. Sequins, sparkle, and glitter can flow into the water supply.

TRANSPORT: New “Wingprint” for Aviation

 

“Dutch roll” animation by Piaschol, 2008. Creative Commons 0, public domain. Included with appreciation.

Flying on leftovers, sugar, fat, and corn waste – recipe for Sustainable Aviation Fuel (SAF) – Virgin Atlantic’s Boeing 787 flew from London’s Heathrow to New York’s JFK, joining Emirates and Gulfstream in demonstrating a new “wingprint” for aviation. In some ways, it was just a proof-of-concept: there were no passengers or cargo. But nevertheless, it is a significant milestone for an industry that seeks climate-sensitive solutions to air transport emissions.

1903 to 2023 – just over a century after the Wright Brothers made the first successful flight of a heavier-than-air craft, aviation has begun to transition to sustainable and renewable fuel sources. Recently, Emirates claimed the honor of being the first airline to demonstrate flight of an A380 with 100% SAF. But the aircraft used SAF fuel in only one of the plane’s four engines. Other aviation industry leaders including Airbus, Engine Alliance, Pratt & Whitney, Neste, Virent and others joined the quest. Just days earlier, Gulfstream Aerospace, leader in business and private air travel, completed a transatlantic flight from Savannah, Georgia to Farnborough airport in England. using 100% SAF. Using Pratt & Whitney PW815GA engines, flight fuel was composed of hydroprocessed esters and fatty acids (neat HEFA) biofuel.

“Types and generation of biofuels” by Muhammad Rizwan Javel, et al., 2019. Creative Commons 4.0. Included with appreciation.

What is Sustainable Aviation Fuel (SAF)? It is a fuel produced from non-petroleum based , renewable “feedstocks” that may include food and yard waste from landfills, fats and greases from leftovers in commercial kitchens, and woody biomass. Suppliers include Neste and World Energy. In the United States. the Department of Energy, Department of Transportation, and other agencies signed a Memorandum of Understanding termed the “SAF Grand Challenge” to produce 3 billion gallons (ll billion liters) per year by 2030 and 35 billion gallons (132 billion liters) per year by 2050.

When the International Civil Aviation Organization (ICAO) met, this week, for the Conference on Aviation and Alternative Fuels, Emirates’, Gulfstream’s, and Virgin’s achievements served to accelerate progress towards the goal of making all aircraft capable of flying with 100% SAF by 2030. Presently, commercial airlines can use only 50% SAF while safety tests continue.

Aviation’s new wingprint – dawn of a era. Image: “Flying through the sunrise” by Lenny K. Photography, 2015. Creative Commons 2.0. Included with appreciation.

SAF could reduce air travel’s carbon “wingprint” by 70%.  How? SAF does emit the same amount of greenhouse gases when airborne, but it is made from plants like corn that have already absorbed CO2 before they were cut. So in a sense, SAF is considered cleaner. SAF does not come cheap: it costs 6 times more than regular jet fuels like kerosene. Another factor is land use. Growing enough plants for biofuels would use a lot of land: in the UK, it would consume half of available agricultural land. Instead of traditional biomass SAF, environmental advocates advise development of synthetic fuels made by blending green hydrogen with carbon captured energy. Innovators in what is termed “synthetic kerosene” include Shell, KLM, and start-up Twelve Corporation. The global SAF market, including synthetic kerosene, is predicted to grow by 47% from 2023 to 2030.

ENERGY/CITIES: Are You in a Circle of Danger?

If you live within 1/2 mile (0.8 kilometer) of a fossil fuel processing plant, you may be in a circle of danger. Image above shows air pollution as it circles the globe. “Air Pollution Earth” by NASA, 2001. Public Domain.

Air pollution is a serious problem worldwide. Burning of fossil fuels, excess vehicular traffic, and lack of green spaces to absorb emissions, are causing clogged skies and public health dangers. Case in point, this month: India.

“Taj Mahal” from a photograph circa 1900. Image source: U.S. Library of Congress. Creative Commons Public Domain. Included with appreciation.

Those who visited India’s famed Taj Mahal may not have been able to see the iconic monument this month. Air pollution fogged India’s skies. New Delhi, home to 35 million people, closed schools and warned residents to stay indoors if possible. NASA’s satellite images showed dense smoke over the landscape. But more troubling was the cause: particulate matter toxins and pollutants so tiny they can pass into human (and animal) airways to cause illness and chronic conditions.

“Air pollution in India from burning of rice residues in SE Punjab, India, prior to wheat season.” By Neil Palmer, CIAT. Creative commons 2.0. Included with appreciation.

Seasonal – in November, farmers clear straw after the rice harvest: it’s known as “stubble burning.” That practice increases normal pollution levels caused by domestic fires for heating and cooking, as well as smog from industry and vehicles.

Diwali fireworks may add to air pollution. “Diwali fireworks, India” by Urbanurban_ru, 2013. Creative commons 2.0. Included with appreciation.

Fireworks: Added Danger – add to present air problems the joyous feast of Diwali, occasion for sky-illuminating, but also air-polluting, fireworks and air pollution becomes more serious. After Diwali, transport authorities are considering calling for an alternation of traffic days, allowing certain vehicles on the road every odd/even day. In some global locations, during seasonal festivals, many cities opt for aerial drone displays rather than traditional fireworks.

Regional – as New Delhi experiences air quality issues, Lahore, Pakistan, home to 13 million people, has also recommended schools, shopping malls, and some businesses, close temporarily. The air quality index (AQI) reached a hazardous level. Air pollution is a transboundary problem.

Pollution Effects Worldwide – 1 in 5 deaths worldwide can be traced to illnesses initiated or worsened by air pollution from fossil fuel combustion. Researchers from the University of Birmingham, University of Leicester, University College, London, and Harvard University found that 8 million people died from causes linked to air pollution in 2018; since then, things have gotten worse.

Circle of Danger – the closer you live to a fossil fuel production facility, the more pollutants you may encounter. Toxins entering the air, and your lungs, include benzene, carbon dioxide, ethylbenzene, formaldehyde, methane, toluene, and xylene. The term for some of these substances is Volatile Organic Compound (VOC). In the United States, there are over 1 million active production wells, natural gas compressor stations, and processing plants, with 12 million people living within 1/2 mile (0.8 kilometer) – the circle of danger.

WATER: Taking “forever” out of PFAS

 

Water is the fountain of life. Let’s remove PFAS forever chemicals from drinking water. Image: “Een oranje vontijn” by graphic artist Japiot, 2011. Dedicated by the artist to the universal public domain, CCO 1.0. Included with appreciation.

Water is the fountain of life: our bodies are over 60% water, and some plants are as much as 90% water. We can live three weeks without food, but only three days without water. But while our body and natural needs have not changed, water has. Industrial chemicals have washed down our drains and into our drinking water supply. These include microplastics found in household cleaning products (think “scrubbers”) and even cosmetics (think “smoothers and fillers”).

PFAS chemicals are endangering our water supply. Image: “Perfluorooctanessulfonic acid, PFAS” by graphic artist Jynto, 2011. Dedicated by the artist to the public domain, CCO 1.0. Included with appreciation.

But among the most troubling additions to our water supply are PFAS (per – and polyfluoroalkyl) compounds called “forever chemicals.”  They are ubiquitous. Have a teflon pan for cooking? You could be adding PFAS to your omelette. Grabbing take-out pizza for the family? If your pie comes in a grease-proof pizza box, that container may have PFAS substances. Serving trout for dinner? Fish from waterways that harbor PFAS may contain the chemicals. It’s a global problem. American companies DuPont and 3M may have started it, but now PFAS chemicals are present in water worldwide. Clean drinking water is one of the first quests of human history, with early achievements like the Roman aqueducts or the New River of England. But Italy now faces PFAS problems, and England’s Environment Agency reported in 2021 that PFAS is widely present in English surface water and groundwater in concentrations of disturbing magnitude. In fact, a recent UK directive goal of achieving good quality of all waterways by 2027 could now need to be revised to 2063, due to the problem of PFAS.

Many PFAS chemicals are dangerous to human health. Image: “Effects of exposure to PFASs on human health” by European Environment Agency, with image vectorization by Mrmw, 2019. Creative commons 2.5. Included with appreciation.

There are more than 8,000 different forever chemicals, many troublingly toxic and stubbornly persistent. PFAS can be damaging to human systems, resulting in hormonal problems and perhaps causing diseases such as cancer. The chemicals are especially dangerous for those who are pregnant. A legal settlement with 3M on PFAS, amounting to $10.3 billion over 13 years and the pledge to exit all PFAS manufacturing in 2025, may pave the way for more action by industry to stop the use of forever chemicals. 3M had some explaining to do to its investors. The settlement was revised and then renegotiated to $12.5 billion, spreading payments out until 2036. But you can take preventative measures now.

I. NOW: Here are two steps you may wish to take now regarding PFAS.

Test your drinking water for PFAS. Image: “Drinking water sign” by Dr. Torsten Henning, 2009 with derivative graphics by Shizhao. Creative commons 3.0. Included with appreciation.

#1 Detection. If you obtain your household drinking water from a municipal source, your local water utility should have relevant data. If not, you can test your household water yourself, using a certified lab with approved testing methods. Need help finding a lab? Here’s a start. Or, if you love dipping your pole in the local lake or river for a day of fishing, in the U.S., you can contact State and Tribal experts for information on your  local water source’s PFAS measurements.

Filter your water. Image: “Biosand Water Filter” by graphic designer TripleQuest, 2010. Creative commons 3.0. Included with appreciation.

#2 Filtration. 

Some households may benefit from using water filtration systems but there are so many kinds of PFAS chemicals with so many different compounds that one-filter-for-all is proving difficult. Sandia National Laboratories is working on an advanced filtration system that will collect many kinds of PFAS substances. However, once you have filtered out the PFAS, be aware that the waste material will be concentrated and highly toxic. Municipalities and cities may need to find a way for households (and organizations including hospitals and schools) to send their filled filters to a safe disposal center. For now, installing an activated carbon filter, made from organic materials with high carbon properties like wood, lignite and even coal, sometimes made with granular activated carbon (GAC), can help. GAC filters work well on longer-chain PFAS (like PFOA and PFOS) but shorter-chain formats like (PFBS and PFBA) may slip through. Resins are an option. In this category, AER filters can remove 100% of PFAS, but the need to change filters often is still a problem. Finally, high-pressure membranes, like nano-filtration or reverse osmosis, can remove PFAS. Nano-filtration membranes remove particles but retain minerals; reverse osmosis removes minerals as well. Membrane filters can remove 90% of PFAS, including the elusive short-chain kinds.

II. SOON: Emerging Innovations and Solutions for PFAS

Destruction

Teflon may contain a particularly durable type of PFAS that can withstand high heat. Image: “Teflon Plan” by photographer MdeVicente, 2014. Dedicated to the public domain by the photographer. Creative commons 1.0. Included with appreciation.

That teflon pan in your kitchen hints at a problem in achieving permanent destruction of PFAS. Teflon is a kind of PFAS called PTFE, and it is specially formulated to remain intact in temperatures as hot as 500 Fahrenheit (260 Celsius). Moreover, when we burn PFAS in its longer-chain form, it merely transforms into short-chain PFAS that floats into the air, and then drifts down into groundwater and eventually pours right back out of your tap water. To combat that indestructibility, a laboratory at the University of British Columbia and a team at the University of California, Riverside, are working on methods using electrochemical and photochemical techniques. Initial results are promising: using low wavelengths of ultraviolet light, scientists are achieving PFAS breakdown. Professor Haizhou Liu, study author, commented that the by-product of this method of destroying PFAS is actually something beneficial – fluoride, the same chemical commonly added to toothpaste that can help strengthen teeth. The system is now entering a larger scale phase with the goal of designing a UV reactor that can process millions of gallons (or liters) per day and can be attached to municipal water treatment plants.

Image: “Acidimicrobium ferrooxidans.” by Manfred Rohde, Helmholtz Centre for Infection Research, Braunschweig, 2009. Creative commons 3.0. Included with appreciation.

Another approach? Microbes. Princeton University found that Acidimicrobium bacterium A6 proved effective at removing 60% o PFOS and PFOA in the lab. A subsequent study at the University of California headed by Professor Yujie Men is exploring bacteria and enzymes that can speed up the “forever” into faster dissolution.

Cessation

“Disappearing” by photographer Dirk Duckhorn, 2013. Creative commons 2.0. Included with appreciation.  Developing a timeline to achieve cessation of harmful PFAS chemical is now underway; eventually, most forever chemicals will disappear. Stopping manufacture and sales of fossil-fuel powered vehicles is a goal with dates. Achieving net-zero carbon emissions is a target with increasingly-agreed timelines. Limiting methane emissions is now a global pledge. With the 3M legal settlement, we are now seeing a proliferation of legal actions regarding forever PFAS chemicals. The very first lawsuit regarding damages from use of PFAS, then aimed at DuPont’s use of PFAS in manufacturing Teflon, (Tennant v. DuPont) was in 1999; it was settled in 2001. Right now, in 2023, thee are 25,000 claims against DuPont and 3M as well as Chemours and Corteva. In the 1990’s, so-called “Big Tobacco” lawsuits amounted to $200 billion. PFAS is on the way to meet or beat that tally. Eventually, we will phase out PFAS. But until then, you can find ways to protect yourself and your family by avoiding products containing PFAS, filtering your home water supply, supporting political and civic initiatives to keep drinking water safe and sustainable. All these approaches will help to achieve United Nations Sustainable Development Goal #6, and will keep you and your family, schools, hospitals, and business organizations, healthier.

TRANSPORT: Silk Road 2.0

The ancient silk road originated in China. Image: “Caravane sur la Route de la Soie” by artist and cartographer Cresques Abraham (1325-1387. Image from Gallica Digital Library. Creative commons public domain. Included with appreciaiton.

While many animals (and a few plants) move around, humans may be the only species that builds roads, ships, and aircraft to do so. Human history can be traced by modes of transport: carts and wheels, ships and sails, trains and rails, tunnels and tubes, roads and vehicles, aircraft and wings, rockets and boosters. The ancient Silk Road, emanating from China around 206 bc, running 4,000 miles (6,437 kilometers), was one of the first extended paths over land. China’s Grand Canal connected to the sea via one of the world’s first inland waterways. Transport is about connection: ancient China achieved both land and sea routes that resulted in cultural and economic exchange.

In 2013, China announced the Belt and Road Initiative. Now, in 2023, here is a map of the project. “Topographic map of the Belt and Road Economic Corridor and pathway cities” by graphic artist, 18 October 2023. Creative commons 4.0. Included with appreciation.

One decade ago, China announced what some call Silk Road 2.0; its formal name is the Belt and Road Initiative (BRI). This week, representatives from nearly 150 countries met in Beijing to consider next steps. One agenda item: debt. China has reportedly financed airports, bridges, hydroelectric facilities, pipelines, ports, and roads in extensive world locations with an understanding that the receiving country would pay back loans and share user fees. There have been criticisms, as well as defaults and delays. Nepal’s new Pokhara Airport opened with a big price tag but as yet small revenue. China recently restructured debt with Argentina, Sri Lanka, and Zambia, among others. Not everyone is staying in the program; Italy had joined but is now trying to leave. But some countries and their leaders are decidedly there: Russia’s Putin was at the meeting, so was Haji Nooruddin Azizi, a minister of the Taliban. (Cash 2023)

Belt and Road Forum representatives, 17 October 2023. Image: from Kremlin.ru. Creative commons 4.0. Included with appreciation.

Perhaps in response to concerns involving environmental and justice concerns, China launched the 2021 Global Development Initiative to promote “economic and social development” with a funding deposit of $10 billion. The total BRI extension in loans and grants is estimated at $1 trillion.

The Belt and Road Initiative has both pro and con issues. Image: “Plus, Minus, and Equality Signs” by graphic artist Sa-se. Creative Commons public domain. Included with appreciation.

While debt is a concerning issue (some say it is a con in the word’s two meanings) so is pollution: China’s overseas fossil-fuel power plants emit 245 million tons of CO2 annually. Another factor is land use change, with further environmental damage and loss of biodiversity, especially to land that is the home of original, indigenous people. However, there may also be pros. China has extended $500 billion in funding that some say could improve the infrastructure and industrial capabilities of some areas that desire growth but may have had challenges getting funding. From any angle, the Belt and Road Initiative is macro and global.

The Belt and Road Initiative may soon circle the world. It is one of the most important macro projects in history. Could the BRI be an opportunity for renewable energy, sustainable water, and perhaps even a new understanding of our interconnected world? How can you get involved to make it so? Image: “Animated Globe with Flags” by graphic artist Meclee, 2012. Creative commons 3.0. Included with appreciation.

The scope and span of the BRI make it one of the most significant agents in climate. The sheer volume of concrete, for example, could influence the environment: what if the BRI instituted a policy regarding the use of concrete as a carbon capture and containment? Ditto BRI’s energy use: as a leader in solar, could China favor renewable technology in BRI projects? BRi may be the biggest and most impactful construction project in history. We need to pay more attention. How can we influence climate and justice decisions? Want to know more? Start here, or  here.

WATER: Saltwater Intrusion – Rolling into the River

Saltwater is rolling in on the Mississippi River. Image: “The waves on the water” by graphic artist Elapros, 2011. Creative commons 4.0. Included with appreciation.

Tina Turner famously sang about Proud Mary Rollin’ on the River. But now the mighty Mississippi River is not rolling with cruise boats. A Viking line riverboat recently set sail but was stuck for an entire day on a sandbar. The Mississippi river is suffering from drought, reducing the river’s freshwater flow and allowing salty water from the Gulf of Mexico to enter the river. Affected are plants, wildlife, and people – including those in the city of New Orleans, Louisiana.

“Skyline of New Orleans, Louisiana, USA” by Michael Maples, U.S. Army Corps of Engineers, 1999. Public Domain. Included with appreciation.

With the drought depleting the Mississippi’s freshwater resources, a saltwater wedge is forming that may reach the urban area by the end of October 2023. Why a wedge? The shape is formed by differences in saltwater (more dense) and freshwater: when the two kinds of water come together, they form a wedge.

 

Salter intrusion can affect the environment. Another concern is the water infrastructure. Image: “Saltwater intrusion” graphic by Sweetian, 2011. Creative commons 3.0. Included with appreciation.

As coastal and river communities consume more water, drawing from available aquifers, seawater can encroach. That affects both farming (5% salinity makes water unsuitable for agriculture) and drinking water (2% salinity renders freshwater undrinkable). Rivers are also an important habitat for flora and fauna, estuarial environments, and wildlife: all of these are affected by salinity.

Salt can corrode. When drinking water distribution systems contain lead in the pipes, results can be disastrous. Image: “Rusted water pipe” by photographer Geographer, 2008. Creative commons 3.0. Included with appreciation.

While salty water is dangerous for a number of environmental reasons, another serious concern is its corrosive effect. Some of pipes in New Orleans’ water distribution system may still have lead. This is the case for many American cities whose pipes are older than 1986, when a law was passed that prohibits using lead in water systems. One million people in southeast Louisiana are on watch and in danger. Flint, Michigan suffered a tragedy when lead from its aging system leached into drinking water: by the time pediatrician Dr. Mona Hanna-Attisha noticed lead poisoning among patients, a generation of children were stricken. Medical treatment was $100 million; fixing and replacing the outdated pipes: $1.5 billion. Even where lead is not present, other dangerous heavy metals can be released. Anti-corrosion products are available, and the New Orleans has called a public works meeting to plan a corrosion monitoring program.

One option? Bottled water. Image: “Lots of bottled water” by photographer Nrbelex, 2006. Creative commons 2.0. Included with appreciation.

New Orleans, and the communities in southeast Louisiana, can take action now, before it is too late. But what are the options? Like the people in Flint, families can purchase bottled water. A suburb of Nola, Metaire (whose interchange of I-10/I-610 is subject to flooding) reported sales of 2,000 bottles of water daily. In New Orleans, large institutions needing water, like hospitals, were stockpiling in advance. Maybe it could be a short-term option, but it’s an environmental and health risk – over one million plastic bottles of water are sold globally – every minute! Studies reveal water from plastic bottles leaches microplastics into the human system. And then there’s the reality that very few plastic water bottles are recycled, with most ending up in landfills, river, and oceans.  Bottled water is not a long-term answer.

The U.S. Army Corps of Engineers built a sill and can improve that structure. Image: “Sill” by graphic artist Meninanatureza, 2021. Creative commons 4.0. Included with appreciation.

What about macro solution? In July 2023, the U.S. Army Corps of Engineers placed a “sill”  in the Mississippi River as a kind of barrier to influx of salt water from the Gulf. Now, plans are in process to raise the sill barrier by 25 feet (7.62 meters). But even at the new height, the project will only delay the inevitable by 10 or so days. Another large-scale option is building a pipe to bring fresh water from upstream. It’s like what China did with the Grand Canal – bringing water from the south to the north – but in reverse. Possible, but expensive, and not a guarantee that enough fresh water will be available in the upper river if drought conditions persist.

The MIT desalination device is the size of a suitcase. Image: “Belber Vintage Striped Suitcase,” by photographer Sandrine Z, 2014. Creative Commons 4.0. Included with appreciation.

One further option, especially if saltwater continues to flow from the Gulf of Mexico, is new desalination technology developing at MIT. The Device Research Laboratory’s Lenan Zhang and Yang Zhong, along with Evelyn Wang and team, working with Shanghai Jiao Tong University and the National Science Foundation of China, announced development of a system the size of a suitcase that can filter high-salinity water, delivering 1.32 gallons (5 liters) of drinking and cooking water per hour. It can be installed at households, and is free from electricity, running on solar power. The system is new design that solves the formerly-intractable problem of salt buildup that clogs many desalination devices. Overall, the cost of delivering drinking water is cheaper than tap water. In a feat of biomimicry, the device by thermohaline processes – (temperature “thermo” + salinity “haline”) – just like the waves of the ocean. (Chu 2023).

Mangrove leaves can excrete salt. Image: “Avicenna germinans  –  salt excretion” by photographer Ulf Mehlig. Creative commons 2.5. Included with appreciation.

Or where suitable, there is the mangrove. This coastal plant can thrive in salty environments and may even act as a filter; some mangrove leaves are able to excrete salt. Mangrove trees can help to regulate salinity: they thrive in the intertidal zones where salt and fresh water mix. Avicenna officinalis (see above) is one of the salt-secretors; this mangrove tree has evolved salt glands in the tissues that release salt.

There are more than 500 port cities endangered by saltwater intrusions; it is a challenge offering scalable innovation. Image: “Earth-Globespin” by NASA, 2015 Public Domain. Included with appreciation.

Will New Orleans serve as a case example? Other salt water wedges can be found in the estuaries of the rivers including the Columbia River of Oregon and Washington states, or the Hudson in New York. And, saltwater intrusions are not restricted to the United States. The Po River in Italy suffered damage in the Po Plain where salt water from the Adriatic entered the freshwater river: drainage from agricultural land worsened the salinization process.  In Bangladesh, southwestern coastal regions are also threatened by saltwater intrusions causing soil damage and compromising drinking water: cyclones and storm surges exacerbate the threat. Seawater intrusion is now a major problem worldwide: it even has its own acronym (SWI). Alarmingly, 32% of world coastal cities are threatened by saltwater intrusion: 500 cities are in urgent danger.
