Presentation Transcript

Chapter 14 water pollution.

Water Pollution • Water pollution- the contamination of streams, rivers, lakes, oceans, or groundwater with substances produced through human activities and that negatively affect organisms. • Point sources- distinct locations that pump waste into a waterway. These are easily identified • Nonpoint sources- diffuse areas such as an entire farming region that pollutes a waterway. These are more expensive and difficult to clean up.

Can you identify which of these is point source Pollution?

Categories of Water Pollution • Sewage • disease-causing agents • sediment pollution • inorganic plant and algal nutrients • organic compounds • inorganic chemicals • radioactive substances • thermal pollution • Noise pollution

Water Pollution is a Problem Worldwide Half of the world’s major rivers are seriously depleted and polluted They poison surrounding ecosystems Threaten the health and livelihood of people The invisible pollution of groundwater has been called a “covert crisis”

Water Pollution Over two-thirds of U.S. estuaries and bays are severely degraded because of nitrogen and phosphorous pollution Every year almost 25% of U.S. beaches are closed at least once because of water pollution Over 73 different kinds of pesticides have been found in the groundwater that we eventually use to drink 1.2 trillion gallons of sewage, storm water and industrial waste are discharged into U.S. waters every year A large number of U.S. rivers are too polluted for aquatic life to survive Americans use over 2.2 billion pounds of pesticides every year, which eventually washes into our rivers and lakes

Leading causes of water pollution • Agriculture activities • Sediment eroded from the lands • Fertilizers and pesticides-almost all waters are polluted with pesticides • Bacteria from livestock and food processing wastes • Industrial facilities- heavy metals, corrosive materials organic and non-organic chemicals • Mining- acid drainage pollutes water by leeching out heavy metals

Agriculture major source of water pollution • Agriculture is leading source of water pollution in US • Animal wastes and plants residues have high BOD • Chemical pesticides can leach into groundwater • Almost all streams and rivers are polluted with agricultural pesticides

Agricultural Runoff is the main cause of the Dead Zone in the Gulf of Mexico; The U.N. documented 250 dead zones worldwide in 2005

Sediment runoff from farmland is the highest Pollution from agriculture by weight.

Eutrophication • Eutrophication is an abundance of fertility to a body of water. • Eutrophication is caused by an increase in nutrients, such as fertilizers. • Eutrophication can cause a rapid growth of algae which eventually dies, causing the microbes to increase the BOD and oxygen levels to fall eventually may cause a die-off of all organisms.

Solutions to Reduce Eutrophication • Phosphate-free detergents • Planting vegetation to increase nutrient uptake • Treat wastewater • Reduce fertilizer application

Different industries add different pollutants • Food processing plants- high BOD • Paper mills- High BOD and toxic compounds • Textile industry-the World Bank estimates that 17-20 percent of industrial pollution comes from textile industry with 72 toxic chemicals being added to water

According to Greenpeace, the discharge from these factories includes heavy metals and “hazardous and persistent chemicals with hormone-disrupting properties” were found being discharged from China’ s factories

Heavy Metals and Other Substances that can threaten human Health and the Environment • Lead • Arsenic • Mercury • Acids • Synthetic compounds (pesticides, pharmaceuticals, and hormones)

More on heavy metals • Lead • Found in old paint, industrial pollutants, leaded gasoline • Mercury • Mercury bioaccumulates in the muscles of top predators of the open ocean

Arsenic found naturally in rocks and water • When arsenic is found in water, it may be from natural causes • Highest levels of arsenic in U.S. found in upper Midwest and West • Individual wells dug in Southeast Asia-many are contaminated by arsenic causing arsenic posioning

World Mercury Production from Human Activities

Pharmaceuticals and Hormones Found in Water

Industrial Compounds • Chemicals used in manufacturing • Local examples include PCBs in Hudson River from General Electric Co. and cadmium from foundry in Cold Spring • PCBs cause brain damage, are lethal and carcinogenic

Oil Pollution

Marine pollution threatens resources • Even into the mid-20th century, coastal U.S. cities dumped trash and untreated sewage along their shores • Oil, plastic, chemicals, excess nutrients make their way from land into oceans • Raw sewage and trash from cruise ships • Abandoned fishing gear from fishing boats In 2006, 359,000 Ocean Conservancy volunteers from 66 nations picked up 3.2 million kg (7 million lbs.) of trash

Ways to Remediate Oil Pollution • Containment using booms to keep the floating oil from spreading. • Chemicals that help break up the oil, making it disperse before it hits the shoreline. • Bacteria that are genetically engineered to consume oil

Water Pollution from Mining • Acid Mine Drainage-low pH of water causes iron to precipitate from pyrite and cause a rusty red color • Heavy metal contamination and leeching • Mine waste and tailings • Processing chemicals pollution • Sedimentation of waters and erosion

Mining often pollutes waters

Other Water Pollutants • Solid waste pollution (garbage) • Sediment pollution (sand, silt and clay) • Thermal pollution • Radioactive pollution • Noise pollution

Solid Waste Pollution • Much solid waste is garbage • North Pacific Gyre-Great Pacific Garbage Patch • Plastic waste is dangerous to marine animals and humans • Found in the stomachs of dead baby sea birds as parent birds think the small pieces of plastic is phytoplankton.

Plastic rubbish deposits

Plastic Pollution of Water • Plastics can release harmful chemicals into the water • Plastic is a synthesized organic compound (carbon-hydrogen bonds) that does not decompose • Plastic breaks up into extremely tiny pieces that is mistaken for food by many organisms.

Sediment Pollution • Excessive amounts of suspended soil particles • Originates from erosion of agricultural lands, forest soils exposed by logging, degraded stream banks, overgrazed rangelands, strip mines, and construction • Problems • Limits light penetration • Covers aquatic animals and plants • Brings insoluble toxins into waterways

Land disturbance results in poor water quality • Clear-cutting, mining, poor cultivation practices • Dramatically changes aquatic habitats, and fish may not survive • Solutions: better management of farms and forests; avoid large-scale disturbance of vegetation

Radioactive Substances Contain atoms of unstable isotopes that spontaneously emit radiation Sources Mining Processing radioactive materials Nuclear power plants Natural sources

Thermal Pollution Occurs when heated water produced during industrial processes is released into waterways Temperature affects digestive rates, heart rates, and respiration rates Warmer water holds less dissolved oxygen Removing streamside cover also raises water temperature

Noise Pollution • Sounds from ships and submarines • Sonar equipment could negatively affect whales, causing them to be beached • U. S. Military exempt from environmental laws related to sonar use

Organic Compounds found in Polluted Water

Human Wastewater • Water produced by human activities such as human sewage from toilets and gray water from bathing and washing clothes or dishes.

Why human and animal waste water needs to be treated Pathogens and toxins enter water supply via inadequately treated human waste and animal waste via feedlots Causes more human health problems than any other type of water pollution

Three reasons scientists are concerned about human wastewater: • Oxygen-demanding wastes like bacteria that put a large demand for oxygen in the water • Nutrients that are released from wastewater decomposition can make the water more fertile causing eutrophication • Wastewater can carry a wide variety of disease-causing organisms.

Biochemical Oxygen Demand (BOD) • BOD- the amount of oxygen a quantity of water uses over a period of time at a specific temperature. • As BOD increases Dissolved Oxygen (DO) decreases • Lower BOD values indicate the water is less polluted and higher BOD values indicate it is more polluted by wastewater.

Sewage and pollutants in drinking water • Currently, 1.1 billion people are without safe drinking water • 2.4 billion have no sewer or sanitary facilities • Mostly rural Asians and Africans • An estimated 1.6 to 5 million people die per year from unsafe drinking water

Common Diseases from Human Wastewater

Major Water Pollutants and Their Sources Table 20-1, p. 532

Solutions • Treat sewage • Disinfect drinking water • Public education to encourage personal hygiene • Government enforcement of regulations

Treatments for Human and Animal Wastewater • Septic systems- a large container that receives wastewater from the house.

Treatments for Human and Animal Wastewater • Sewage Treatment Plants- centralized plants in areas with large populations that receive wastewater via a network of underground pipes. • Test for human and animal waste using fecal coliform bacteria test

Table of contents.

Water is one of the inevitable elements in our daily life. One of the studies conducted in Archiv Fur Kriminologie concluded like this. Humans will not be able to live more than 8 to 21 days without water. This conclusion points out the necessity of saving and conserving water. As we all know, almost 71 percent of the earth’s surface is water-covered. But in this, only 1 percent is freshwater which is accessible to us. This reality again emphasizes the importance of saving water and preventing water pollution.

“Water is Precious. Save Water”

Here we are focusing on the causes of water pollution and its remedies. In addition, we will discuss things that we can do to prevent water pollution. First, let’s look into what is water pollution?

What is Water Pollution?

In simple words, it is the contamination of usable water by harmful substances like chemicals or microorganisms by any means. On the other hand, activities reducing the quality of water are called water pollution.

Freshwater sources like rivers, lakes, and ponds are getting polluted in the name of industrialization. For instance, domestic wastes, food processing wastes, livestock operations can leads to the contamination of freshwater sources. Apart from all these, we humans pollute freshwater sources like ponds, rivers, and water streams by throwing household wastes and scraps into them.

How does the water get polluted?

Without any doubt, we can say that freshwater sources around us are getting polluted every day. Industrialization is one of the reasons for water pollution. The majority of the factories are dumping wastes, garbages, and sewages into nearby rivers, ponds, or lakes. The minority reprocess and resues the wastewater and substandard water.

Corporate industries are not worried about the surroundings and people living nearby. The ignorance and irresponsibility of the municipality and responsible people make the situation even worse.

In some places, the household sewage is connected to the rivers since they do not have proper sanitation and septic tank facility. It leads to one of the worst water pollutions where we knowingly pollute usable water. Earlier, urban areas were ahead in water pollution when comparing to rural areas. But now, things have changed a lot. The rate of water pollution has increased by 5x in both urban and rural areas. One of the reasons for this massive increase in pollution is the emergence of industries and factories in urban areas.

One of the practices seen in villages is washing clothes and feeding animals in the small rivers and ponds. At the same time, they wash these cattle and animals in the pond. It can directly harm the water sources when activities like this happen in a massive volume. And the other, people throw wastes into the rivers and ponds. In rural areas and villages, people even food wastes into water streams. Whatsoever, water is getting polluted every day. Here are some of the popular ways of water pollution around the world. Let’s look at some of the common causes of water pollution. Here are they.

Wastewater from factories & industries

Industries and factories use water for many purposes. Without water, manufacturing and production can’t exist. They use water for cleaning, cooling, washing, dyeing, and treatments for manufacturing and production processes. Water pollution is happening behind all industrial activities. In that, textile industries are the biggest polluters on the planet. Studies say that one-fifth of the world’s industrial water pollution comes from textile mills. For example, in China, 25% of water pollution happens through textile dyeing and treatments. Almost more than 25000 types of chemicals are mixed and used in the dyeing process of fabrics. These mixed chemicals are thrown away from the facility to any of the flowing water bodies.

The reason behind not building proper recycling and reusing units is because of high maintenance costs and implementing costs. If the companies and factories do the right thing, the pollution will come down to half. None of the government authorities check these requirements while approving the factories to operate.

Some factories produce mixed water as a byproduct of the chemical reactions that happened from their day-to-day industrial activities. This water contains chemicals substances that can be dangerous to us.

Oil leaks & spills

It is common knowledge that oil and water never dissolve completely. But it can be together like that for a long time. Oil act as a cover when it spilled on water. It can remain as long they want and thereby making it polluted. Oil spills and leakages happen very often in oceans. Sometimes from the ships that transport oil or from drilling and mining operations held underwater or seashores. These are also some of the main causes of water pollution.

Use of chemicals & pesticides in agriculture.

It is rare but happens often. When it comes to the massive use of pesticides and chemicals in agricultural lands. It becomes one of the causes of water pollution. The chemicals and pesticides dissolve in the soil after a couple of weeks. Through this, the loam gets saturated with chemicals and pesticides. When the monsoon comes, these chemicals and pesticides come out with rainwater and flows to any of the water resources like wells, ponds, rivers, and sea. It causes one of the dangerous water pollutions if we consume this water.

Why do we need to save water?

Humans cannot survive without drinking water. So it is our duty and responsibility to save and protect water from being polluted. Without drinking water, humans and animals will die. What will happen if we do not do anything? Well, right now we might have enough water resources and backups. But in the coming future, there will be a scarcity of drinking water even if we have hundreds of water purification or processing plants. So it is better to save water resources and water right now when we can.

Do you think we can survive on the earth without water? No, we cannot. It is an essential factor that holds our life. Even animals will die if the freshwater sources are over. There will be no animals and living organisms left if the water pollution rises on a huge scale. So, it is our responsibility to protect freshwater sources from being polluted.

As said earlier, the volume of fresh water on the earth is decreasing every single day. It is better to save water being wasted and polluted whenever we can. For instance, think about you are walking on a road and see a broken public water pipeline and leaks water leaks heavily. As a man who understands the value of water, we should call the respective authorities and inform them. Because they may not know about the broken pipe and water is being wasted.

How can we prevent water pollution?

By implementing proper waste management facilities, we can reduce water pollution to a considerable amount. The cause of the continuous increase in water pollution is the indigent waste management systems in factories, companies, and homes. As well as a brainy human being, stop throwing wastes mainly into water sources like ponds and rivers.

As a single human being, we have limited control over the rate of water pollution. But as a group of human beings, we can control the rate of water pollution to a substantial amount. So what we need can do is, we can aware people around us about water pollution and its future outcomes.

What each one of us can do?

It is our duty to conserve water from pollution. The fun fact is, nobody is even thinking about saving or protecting it for the coming generation. There might be plenty of water resources right now. But if its keeps getting polluted at a rapid rate, it is sure that these water streams would not last much in the future.

It is effortless to say that save water and prevent water pollution. But when it comes to daily practicality, none of us think about protecting water. We all do things that pollute our precious water sources. For instance, we all throw household garbages and plastic wastes into nearby rivers and ponds. Sometimes, we throw garbages into lands where it somehow reaches the water bodies through rain or water flow after a couple of months or years. In short, each one of us is responsible for water pollution in some ways with or without knowledge.
