POLLUTED EARTH A fresh and engaging introduction to the science behind pollution disasters for science and non-science majors Coming generations will have to reckon with a growing number of environmental challenges, whether caused by climate change, population growth or industrial production. Polluted Earth: The Science of the Earth's Environment combines the best features of a textbook and a popular science book. It retains the organization needed for a course while adopting a highly illustrative style that is mirrored in a multitude of case studies: short, self-contained and well-illustrated stories of well-known pollution disasters that are highly engaging for both science and non-science majors, from the historic Black Sunday dust storm in the midwestern United States to the more recent Deepwater Horizon spill in the Gulf of Mexico. From the very start, it also introduces the concept of environmental justice that ties pollution to economic and social life, bringing its subject into the world of the reader in an unprecedented way. Polluted Earth readers will also find: * Well-known case studies including the Great London smog, the Pacific Gas and Electric case (made famous by Erin Brockovitch), the Exxon Valdez, and more * Detailed illustrations showing the spatial and temporal relations of various pollution sources * Modern technological solutions already in use by environmental industries * A comprehensive list of pollutants, their health & environmental impact and their regulated exposure limits With its fresh and engaging style, Polluted Earth is an ideal introduction to the concepts, tasks and challenges of environmental science for undergraduate students of all disciplines.

Preface

Most environmental textbooks are written in a scientific style and approach the subjects in a traditional manner. However, recent changes in society and especially in the outlook of young people have emphasized concern over environmental justice. Damage to the environment commonly includes injustice. Most environmental textbooks, however, deal only peripherally with this aspect and therefore do not engage students as well as they could. In contrast, this textbook introduces environmental justice, including environmental racism, in Chapter 2, thereby giving instructors the opportunity to set up the course to be viewed through that lens. Once students understand how environmental damage can be focused in areas and situations where socially and economically underprivileged people and groups are taken advantage of, they will be able to recognize it in all of the other chapters and examples in the book. This puts the importance of the course material in a much broader and more pertinent context. This allows the course to satisfy personal, department, and institutional priorities on social issues. Otherwise, instructors may skip Chapter 2 and present the course in a more traditional manner.

In addition, introductory environmental courses are primarily attended by non‐science majors. These students are commonly not accustomed to the organizational and writing style of science textbooks and consequently have a difficult time with them. Much of the problem is that chapters must be read sequentially in one sitting or students lose their train of thought and are forced to start over. Chapters typically involve increasing complexity of concepts. Wading through scientific information at college level is foreign to most of these students.

This book contains the chapters and organization needed for any environmental course but most of the content is delivered through a plethora of exciting case studies. These are short, self‐contained, and well‐illustrated stories of specific pollution disasters and their outcomes that are highly engaging for both science and non‐science majors. The stories incorporate the science into the description so students appreciate and remember it as part of the story. By relating the event to the impact on society and human lives, this method also places the science into a context that is important to the student. The case studies are self‐contained, so chapters can be read in pieces without losing continuity. However, the chapters are organized to deliver the material in the logical manner of the topical development. Therefore, the book can be used as a stand‐alone resource and be effective for exam preparation.

In addition, a list of readily available videos is compiled for all but a few of the case studies. They either provide interviews with victims of the pollution to give readers a look into the emotional aspect of being subject to pollution or they illustrate complex situations to give a better understanding. Reinforcement of reading the case studies with viewing a video leads to a better understanding and appreciation of the situation. It is recommended to watch the videos after reading the case study. The videos are primarily divided into short presentations, typically 3–5 minutes but less than 12 minutes in length. Long videos are typically 30 minutes or longer and are documentaries. These videos also enhance the impact of the course.

The book is organized to introduce the scientific basis of the polluted media either early in the chapter or in a separate leading chapter. These are interspersed with case studies or followed by a group of case studies to give the reader a flavor of the character of the processes and damage. This organization coupled with the exciting and highly illustrated stories is intended to enhance interest and understanding.

The other important feature is the visual support of the case studies. A number of artistic, highly detailed illustrations of regional pollution sources serve as lead‐ins to the case studies. The pollution types include point source versus non‐point source, groundwater pollution, surface water pollution, and ocean pollution. These illustrations show the spatial and temporal relations of the various sources. Each case study then describes a specific example of the pollution source and how it became a pollution disaster. The case study can then be related back to the illustration to place it in context. Case studies on interesting pollution disasters involving each of these is presented in two‐page stories illustrated with several photographs of the event and results.

There is also a compilation of pollutants, their health and/or environmental impact, and the regulated limits on exposure. In this way the students have a single location to view these pollutants and their attributes rather than having them repeated multiple times in the book.

1.1 Human Impact on the Environment

Aside from a possible major war or very deadly pandemic, the greatest challenge humans are facing and will face for the foreseeable future center around pollution of the natural environment. Climate change as a function of human impact has taken center stage over the past few decades. US Vice President Al Gore and, more recently, Swedish student activist Greta Thunberg have become media sensations by bringing climate change to public attention. Society has even made an attempt to address it with hybrid and electric cars, solar panels, and wind farms. However, climate change is only one small aspect of the horrific problems plaguing the natural environment. Dead zones in the oceans from overuse of fertilizers, loss of pollinators from overuse of pesticides and habitat destruction, invasive species destroying native species and resulting massive extinctions are some of the less prominent but just as deadly issues. The new environmental spokespeople are helping to bring attention to some of these issues but all pale in comparison to the original and true environmental champion in America and indeed the world, Rachel Carson. She has been called the “mother of the American environmental movement” but this title does not nearly reflect the magnitude of her impact. During a time when few gave more than a fleeting thought to the natural environment, Rachel Carson brought her serious concerns to the highest level of the government and to the attention of the general public both in the United States and internationally. Her work started the entire study of the environment. She is a true hero.

Humans are notoriously damaging to the natural environment. Even in primitive cultures, groups of humans would cut down trees, make fires, move and break rocks, leave excessive waste, and strip areas of game and vegetation. It took several decades of natural processes for the areas to recover. Once humans established permanent settlements, the environmental damage became very localized but much more intense. The permanent structures, agriculture, and concentrated waste completely disrupted the natural environment and would take centuries to recover once abandoned. The first serious chemical pollution coincided with the Bronze Age and Iron Age which added mining, smelting, and forging of metals. These caused poisoning of air, soil, and water, and death of plants and animals in localized areas.

As civilization advanced, the building of stone structures on ever grander scales led to even greater environmental disruption. Settlements grew ever larger into cities, requiring larger agricultural efforts to support them. Forests were removed to support the production of food. Cities and structures built thousands of years ago still scar the landscape even if they are abandoned. Several inventions occurred over the centuries that accelerated the environmental damage. Gunpowder and arms that utilize it was a major change in environmental damage in addition to the humans killed by them. Paints, dyes, glass, burning of coal, and other chemical developments furthered this damage.

The Industrial Revolution brought a drastic change to the level of environmental impact. The first major pollutant was from mining and use of coal. It produces soot from burning but also from mining and storage. Coal powered the Industrial Revolution and it was spread widely by trains. In addition to dust, the impurities such as sulfur, mercury and other heavy metals, and coal caused widespread soil pollution by emissions and dumping of waste. Dumping dangerous and unsightly waste and emissions was the norm for the Industrial Revolution. As more dangerous contaminants were developed, the pollution intensified and increased. It was not until the environmental movement of the 1950s through 1970s that these practices were even slightly controlled.

Concurrent with the advancement of technology and largely as a result, the human population ballooned. The world population increased slowly from less than one half billion in 1000 AD to 1 billion in 1800. The accelerated growth began soon after and the population reached 2 billion by 1930 (Figure 1.1). In 1950, the acceleration of world population became exceptional, growing from about 2.5 billion to 7.8 billion over the next 70 years. This is far more than the Earth can handle and most environmental systems, both chemical and biological, are being overwhelmed. So many people are contributing to pollution problems that they will be difficult to control, if they are controllable at all. It will take a cooperative effort to keep the run‐away overuse of resources and disruption of the environment not to destroy the human race and the planet.

Pollution has now caused irreparable damage to the Earth for the foreseeable future. The result of human impact is that the Earth is experiencing what is widely believed to be the sixth major mass extinction event in the past 500 million years. It is estimated that more than 25% of all the known species will go extinct by 2050. It is not only the environment that is impacted by pollution but groups of humans are chosen to be more impacted than others based on economic status, whether they are in a developed country or not, and on race and ethnicity. This inequality has evolved into the field of environmental justice.

CASE STUDY 1.1 Rachel Carson (1907–1964)

Mother of the Environmental Movement

Rachel Carson is regarded as the mother of the American environmental movement (Figure 1.2). It was through her efforts that the first banning of pesticides and especially DDT occurred. Her work also led to the formation of the US Environmental Protection Agency. It is impressive that such a private, unassuming woman could influence such a major movement. Carson captured the interest of the American public and the top levels of government despite the efforts of major chemical companies to suppress her work and to professionally and personally discredit her. She testified before the US Congress about the dangers of pesticides. President Kennedy read her book Silent Spring, and as a result, he ordered an investigation of the pesticides that Carson identified as dangerous. They would be banned less than a decade later.

Rachel Carson was born on 27 May 1907, in Springdale, Pennsylvania. She grew up on a small farm, where she developed her love of nature. In 1925, she enrolled in the Pennsylvania College for Women, which later became Chatham College. She began her studies as an English major but soon changed to biology and graduated magna cum laude in 1929 with a bachelor's degree. Carson received a scholarship to continue her education at Johns Hopkins University where she earned a master's degree in zoology in 1932. Her thesis was “The Development of the Pronephros during the Embryonic and Early Larval Life of the Catfish.” She then taught zoology at the University of Maryland and conducted research at the Woods Hole Oceanographic Institution, Massachusetts during the summers.

Rachel Carson began a part‐time position at the US Bureau of Fisheries in 1935, writing science scripts for the radio show Romance Under the Waters. She also wrote articles on natural history for the Baltimore Sun. Her part‐time position transitioned in 1936 into a full‐time position as junior aquatic biologist. Carson was the first woman in the United States to take and pass the civil service exam. She rose through the ranks of the US Fish and Wildlife Service, the succeeding division, over the next 15 years, ultimately becoming the Chief Editor of its publications. Rachel Carson also wrote several books that were successful enough to allow her to retire in 1952 at age 45. She built a cottage on the Sheepscot River near West Southport, Maine, and also kept a residence in Silver Spring, Maryland. In retirement, she completely devoted herself to writing.

Rachel Carson's life included extensive personal tragedy. In 1931, the Carson family had to give up the farm because of pressures of the Great Depression but also because large chemical plants were built on both sides of the farm. They reduced the value of the property as well as its productivity. In 1935, Rachel's father died suddenly which left her to care for her mother. Her sister died the next year leaving Carson and her mother to raise her two orphaned children. Her niece then became ill in 1959 and died and Carson adopted her orphaned son. Her mother died that year and Carson was diagnosed with breast cancer. She battled the illness but succumbed to it on 14 April 1964 in Silver Spring, Maryland, at 56 years of age.

Rachel Carson faced many hurdles to publishing her work. Her first national article was published in Atlantic Monthly magazine in 1937 and entitled “Undersea.” Her first book was published in 1941 and entitled Under the Sea‐Wind. It received positive reviews but went largely unnoticed because America was focused on the start of World War II. Carson's writings became more geared toward environmental activism as her interest grew. Her writing on the origin and properties of the oceans was rejected by 15 magazines, including the Saturday Evening Post and National Geographic Magazine. It was finally published in the New Yorker magazine as a collection under the title A Profile of the Sea. Parts of it were also published by Nature, The Yale Review, and Science Digest. In 1951, the full collection was published as the book The Sea Around Us. It sold more than 200 000 copies in hard cover in its first year and was on the New York Times bestseller list within 2 weeks. It remained on the list for a record 86 weeks, 39 of which it was the top seller. As a result, it won the John Burroughs Medal, the 1952 National Book Award, and it was the Outstanding Book of the Year in The New York Times Christmas Poll. Carson was awarded honorary doctoral degrees from Oberlin College and Pennsylvania College for Women for these achievements. As a result of this popularity, Under the Sea‐Wind was rereleased and made the New York Times bestseller list. The next book, The Edge of the Sea, was released in 1955 and was also on the bestseller list. The National Council of Women of the United States named it the Outstanding Book of the Year, and Carson received the Achievement Award from the American Association of University Women as a result. Carson also published additional articles including “Help your Child to Wonder,” in Woman's Home Companion in 1956. The book The Sense of Wonder was released posthumously in 1965. She wrote her final and most famous book Silent Spring as a result of her environmental activism from 1957 to 1961. The writing was first published in installments in June of 1962 by the New Yorker before it was published as a book later that year. It was at the top of the bestseller list within two weeks and remained on the list for many years.

It was the book Silent Spring that elevated Carson to the position of leader of the environmental movement. In 1992, Silent Spring was declared the most influential book of the past 50 years by a US Congressional panel. It was ranked among the 25 greatest science books of all‐time by Discover Magazine. It has been compared to Harriet Beecher Stowe's Uncle Tom's Cabin and Charles Darwin's On the Origin of the Species in terms of overall impact. Silent Spring declared that chlorinated hydrocarbons and organophosphates were the most dangerous pesticide pollutants and it identified specific compounds, in particular DDT. It also proposed the term “ecosystem”, which is now an important concept in environmental research.

Carson reported the death of hundreds of songbirds in Massachusetts as the result of spraying for mosquitoes, damage from spraying DDT in Long Island, New York, poisoning of workers and farmers in the south from pesticide use on fire ants, and the banning of cranberries for Thanksgiving in 1959 because of overuse of pesticides. These events caused a public furor, setting the stage for Silent Spring. Several attempts to discredit Rachel Carson by chemical companies served to confirm her as the leader of the American environmental movement. Her writings were added to the US Congressional Record and she received an award from the Secretary of the Interior in 1962. Carson was introduced as the originator of the environmental movement when she testified to the US Congress in 1963. As a result of her work, in 1962, over 40 bills were introduced to regulate pesticide use in several states. On 3 April 1963, Carson appeared on national television to explain pesticide dangers. Her death from breast cancer in 1964 is suspected to have resulted from exposure to the chemicals she was attempting to protect the public from. Most of the pesticides identified by Carson were eventually banned. Time magazine named Carson as one of the most influential people of the twentieth century. In 1980, President Jimmy Carter posthumously awarded Carson the Presidential Medal of Freedom. Rachel Carson is a true champion of the environment.

1.2 Earth's Environments

The Earth has a multitude of environments (Figure 1.3) which can be divided by a number of factors both geographical and ecological. Only some of the major environments are described here. The main division is between marine and non‐marine or terrestrial. Marine environments are those not on land, so in oceans, seas, and gulfs. There are coastal environments at the marine‐continental boundary, primarily beach environments and including barrier islands with the lagoons landward of them. They also include deltas where rivers build land into the ocean and estuaries where ocean water floods back up the river. Areas that flood during high tide but are otherwise land are tidal flats. There are also ocean islands and atolls far from the shore.

FIGURE 1.3 Diagram illustrating several environment types.

FIGURE 1.4 Bar graph showing average annual precipitation for several environments.

Within the ocean itself, shelf areas are near‐shore and shallow. These are areas of continental crust covered by ocean. Sunlight can penetrate the entire water column in these areas. This is the photic zone and highly productive, including marine organisms inhabiting the seafloor. In contrast, the deep ocean only has the photic zone in the top part of the water column, with minimal life on the seafloor. The mid‐ocean ridge is a volcanic chain in the middle of the ocean that supports a variety of life below the photic zone, primarily on the seafloor.

Terrestrial environments are numerous and both climatic and geographic. Alpine environments are in the mountains and are typically colder, can have glaciers and only support limited life above a certain elevation. Deserts have less than 10 in. (25 cm) of precipitation per year (Figure 1.4). They can be tropical and hot or tundra/polar and cold. The hot deserts are the classic deserts with sand, caliche, and distinct biota. Alluvial environments are also deserts but typically occur in rugged terrains with a variety of geomorphic features and biota. Tropical rainforests typically have rainfall amounts between 69 in (175 cm) and 79 in (200 cm) but sometimes in excess of 390 in (1000 cm). Rainforests are home to 40–75% of all biotic species on Earth. They can be tropical or temperate and each contains a unique biota.

Temperate climates typically contain grasslands, savannas, and forests, though these biomes can exist in the tropics as well. As the name implies, grasslands contain virtually all grasses and are typically dry, with precipitation of 20–35 in. (50.8–88.9 cm) per year with broad temperature ranges. They can support herds of large grazing animals. Savannas are slightly wetter with 30–40 in. (76.2–101.6 cm) of precipitation per year and warmer temperatures than most grasslands. Savannas contain both trees and grasses but the trees are less dense than forests. Deciduous forests receive 30–60 in. (75–150 cm) of precipitation per year, with average temperatures ranging between −22 °F (−30 °C) and 86 °F (30 °C). They are typically composed of densely packed, primarily broad‐leafed trees and support a variety of animals. Aquatic environments in temperate climates are lacustrine, wetlands, and fluvial‐riparian. Lakes and ponds are lacustrine and they have broad expanses of still, open and variably deep water with free swimming fish, vertebrates, and other biota. Wetlands include swamps, bogs, and fens and also contain still water. Most only have minor and small fish, if any, and are dominated by plants, microorganisms, birds, and insects. Rivers and streams are fluvial and are marked by flowing open water capable of supporting fish. The areas along rivers are called riparian.

Very cold regions have several environments as well depending upon temperature and precipitation. Glacial ice forms in polar regions as well as alpine. Polar regions are the coldest regions and are also very dry having between 4 and 40 in. (10–100 cm) of precipitation per year. However, the higher precipitation amounts are at the edges of the glaciers near open water and, by far, precipitation is less than 10 in. (25 cm) per year making it a desert. The tundra is slightly warmer than polar regions and not covered by ice. Tundras are also deserts with less than 10 in. (25 cm) of precipitation per year but contain some permanent vegetation like grasses, moss, and lichen. The taiga is a bit warmer and wetter, with 12–20 in. (30–50 cm) of precipitation per year, 6 months of the year near or below freezing, and a cover of coniferous trees.

1.3 Point Source and Non‐Point Source Pollution

Pollutants emitted to the natural environment, to air, water, or soil are either from point sources or non‐point sources (Figure 1.5). The difference between them is that point source pollution is from a single identifiable source whereas non‐point source pollution is from diffuse sources that might not be easily identified. Point source pollution is usually at much higher concentrations than non‐point source pollution and it can result in disasters, including the loss of human life. On the other hand, they can be addressed quickly and directly. Non‐point source pollution is usually a long‐term effect that can slowly modify the environment to the point of large‐scale changes and problems. They are much more difficult to address.

1.3.1 Point Source Pollution

Point source pollution can be disastrous to the environment and public health but it is generally not aerially extensive. The concentration of the pollutant may be high but the volume of pollutant release is small compared to non‐point sources. Point source pollution is common in groundwater and can be from a number of sources such as landfills, leaking underground storage tanks (USTs) in gas stations, broken pipelines, overflowing septic systems, industrial spills, military facilities, waste pits and lagoons, mines and others where the pollution comes from a single identifiable place or group of related places. The chemistry of the pollution is unique for several of these sources.

Petroleum is a common point source pollutant in groundwater primarily home heating oil, diesel, or gasoline. It typically leaks from USTs at gas stations and homes with oil heat. Other point source pollution in groundwater can be industrial chemicals. BTEX is shorthand for benzene, toluene, ethylbenzene, and xylene, which are volatile organic compounds (VOCs) that commonly occur together. Other common groundwater pollutants include PCE (perchloroethylene) or perc, which is mainly from dry cleaners, and TCE (trichloroethylene), which is a solvent used in degreasing among many others.

Petroleum is also a common point source pollutant in surface water. Fuel spills from oil tanker accidents, oil transfer spills, and even some oil well leaks or blowouts, are more common in marine waters but raw sewage is more common in lakes and rivers. In the United States, raw sewage in lakes and rivers is less common today but in many less developed countries it is still a major problem. Animal waste from stockyards is generally a problem only during storms and floods in developed countries. Acid mine drainage (AMD) is common from active and abandoned mines and is tainted by sulfuric acid that lowers the pH of the surface water. AMD dissolves ions out of mine waste and can contain heavy metal contamination as well. Mines and mineral processing facilities can pollute surface waters with suspended particles of heavy metals and other pollutants. Gold processing can contain cyanide and mercury as point source pollutants.

Soil pollution from point sources commonly coincides with point source groundwater pollution because the liquid pollutant filters through soil to reach the groundwater and some adheres to the soil. Soil pollution is extreme around certain mines and is the source of pollutants in surface water runoff. Animal stockyards form soil pollution point sources. Soil may also contain point source pollution that does not impact water. In the past, most landfills were buried directly into the soil without any protection. Many industrial plants simply dumped waste materials behind or around the facilities. Metals like chromium, mercury, lead, and nickel and radioactive elements like radium were dumped into holes or on the surface.

Point source pollution into the air includes smokestack emissions from incinerators, coal‐fired powerplants, oil refineries, steel and metal refineries, and other sources. These sources produce particulate, polycyclic aromatic hydrocarbons (PAHs), benzene, CO, CO2, nitrogen oxides, sulfur oxides, and vaporized pollutants like mercury. There are many other point sources of air pollution like chemical and other manufacturing plants that use organic chemicals. Evaporation of these VOCs yield air pollutants that are abundant in the atmosphere. Particulate blown from mine spoils, waste piles at manufacturing facilities, trains and dump trucks in the form of dust also produces air pollution. They can contain heavy metals, asbestos, lime, phosphates and other fertilizers, sulfur, and sulfides among others. In addition, there are natural point sources of pollution like volcanoes and forest fires.

FIGURE 1.5 Diagram showing several point (PS) and non‐point sources (NPS) of pollution.

Point source pollution can also come from disasters such as industrial and transportation accidents, war and other attacks, or natural disasters like earthquakes, hurricanes, and volcanoes. If the human toll of these events is great, whether death, injury, loss of property, or just threat, the environmental impact is commonly overlooked. If the toll is not great, then environmental damage will be considered. The exception to this generality is if the environmental impact involves human health and is extensive. An example of this is the 9/11 World Trade Center disaster in which the first responders to Ground Zero have subsequently suffered extensive long‐term health effects.

CASE STUDY 1.2 9/11 World Trade Center Disaster New York

Collateral Air Pollution

The idea to build the world's tallest buildings on the 16‐acre (6.5‐ha) lot in lower Manhattan was planned in the early 1960s to revitalize the area (Figure 1.6a). Construction began in 1966 by the Port Authority of New York and New Jersey. Five blocks were closed and 160 buildings were demolished to make room for the twin 110‐story high buildings. The towers were open in 1972 and quickly became the symbols of American trade and commerce. By 2001, 50 000 people worked in the World Trade Center and tens of thousands of visitors passed through it daily.

On 11 September 2001, terrorists hijacked two commercial passenger airplanes and crashed them into both the North and South Towers of the World Trade Center (Figure 1.6b). More than 2800 people were killed in the crash, fire, and collapse, and victims were still being identified using DNA through 2007. The attacks led the United States to take military action in Afghanistan and Iraq that lasted for decades. The death, destruction, and retaliation dominated the American attention. However, the explosion, fire, and collapse of the towers produced toxic smoke, particulate, and gas that engulfed the disaster area and damaged the health of tens of thousands of residents, emergency response personnel, and construction workers. Approximately 250 000–400 000 people were exposed to the toxic emissions.

The buildings that were directly destroyed included the 110‐story North and South Towers of the World Trade Center, the observation deck, and Seven World Trade Center, a 47‐story office building. The number three World Trade Center, Marriott Hotel was crushed by the tower collapses. Two nine‐story office buildings at four and five World Trade Center and the seven‐story building at six World Trade Center were badly damaged and demolished later. The disaster caused the deaths of 343 firefighters, 66 police officers, and 148 passengers and crew on the airplanes.
