Although natural phenomena such as volcanoes algae blooms storms , and earthquakes also cause major changes in water quality and the ecological status of water, water is only called polluted when it is not able to be used for what one wants it to be used for. Water pollution has many causes and characteristics. Increases in nutrient loading may lead to eutrophication . Organic wastes such as sewage impose high oxygen demands on the receiving water leading to oxygen depletion with potentially severe impacts on the whole eco-system. Industries discharge a variety of pollutants in their wastewater including heavy metals , resin pellets, organic toxins, oils, nutrients, and solids. Discharges can also have thermal effects, especially those from power stations, and these too reduce the available oxygen. Silt -bearing runoff from many activities including construction sites

Introduction Farming Business Homes Water Pollution W ater pollution occurs when a body of water is adversely affected due to the addition of large amounts of materials to the water. The sources of water pollution are categorized as being a point source or a non-source point of pollution. Point sources of pollution occur when the polluting substance is emitted directly into the waterway. A pipe spewing toxic chemicals directly into a river is an example. A non-point source occurs when there is runoff of pollutants into a waterway, for instance when fertilizer from a field is carried into a stream by surface runoff. Types of Water Pollution Toxic Substance A toxic substance is a chemical pollutant that is not a naturally occurring substance in aquatic ecosystems. The greatest contributors to toxic pollution are herbicides, pesticides and industrial compounds. Organic Substance Organic pollution occurs when an excess of organic matter, such as manure or sewage, enters the water. When organic matter increases in a pond, the number of decomposers will increase. These decomposers grow rapidly and use a great deal of oxygen during their growth. This leads to a depletion of oxygen as the decomposition process occurs. A lack of oxygen can kill aquatic organisms. As the aquatic organisms die, they are broken down by decomposers which leads to further depletion of the oxygen levels. A type of organic pollution can occur when inorganic pollutants such as nitrogen and phosphates accumulate in aquatic ecosystems. High levels of these nutrients cause an overgrowth of plants and algae. As the plants and algae die, they become organic material in the water. The enormous decay of this plant matter, in turn, lowers the oxygen level. The process of rapid plant growth followed by increased activity by decomposers and a depletion of the oxygen level is called

Ohio State University Extension Fact Sheet Food, Agricultural and Biological Engineering 590 Woody Hayes Dr. Columbus, Ohio 43210 Nonpoint Source Pollution: Water Primer AEX-465-93 Rob Leeds Larry C. Brown Nathan L. Watermeier Ohio citizens have shown increased concern about the wise use and protection of the state's water resources. This concern grows as Ohio citizens are increasingly affected by state regulations and water protection measures brought about by the federal Clean Water Act of 1987 and its subsequent reauthorizations (see Clean Water Act insert). As with most legislation, regulations and protection measures for water are complex, and the terminology may not be readily understandable to most readers. The purpose of this publication is to help the reader gain a better understanding of the terminology associated with nonpoint source (NPS) pollution and the protection of water resources. The list of terms described here is not comprehensive, but includes terms often used in the context of water-related, nonpoint source pollution in Ohio. This publication is intended for those who at least have a general understanding of water quality. What is Nonpoint Source Pollution?

WATER POLLUTION AND SOCIETY By David Krantz and Brad Kifferstein INTRODUCTION Comprising over 70% of the Earth’s surface, water is undoubtedly the most precious natural resource that exists on our planet. Without the seemingly invaluable compound comprised of hydrogen and oxygen, life on Earth would be non-existent: it is essential for everything on our planet to grow and prosper. Although we as humans recognize this fact, we disregard it by polluting our rivers, lakes, and oceans. Subsequently, we are slowly but surely harming our planet to the point where organisms are dying at a very alarming rate. In addition to innocent organisms dying off, our drinking water has become greatly affected as is our ability to use water for recreational purposes. In order to combat water pollution, we must understand the problems and become part of the solution. POINT AND NONPOINT SOURCES According to the American College Dictionary, pollution is defined as: “to make foul or unclean; dirty.” Water pollution occurs when a body of water is adversely affected due to the addition of large amounts of materials to the water. When it is unfit for its intended use, water is considered polluted. Two types of water pollutants exist; point source and nonpoint source. Point sources of pollution occur when harmful substances are emitted directly into a body of water. The Exxon Valdez oil spill best illustrates a point source water pollution. A nonpoint source delivers pollutants indirectly through environmental changes. An example of this type of water pollution is when fertilizer from a field is carried into a stream by rain, in the form of run-off

Water Pollution So that you can become a water pollution expert, first we'll investigate different kinds of water pollution. And when you're ready, you can help clean up an oil spill! One kind of water pollution, which is usually the most common, is called CONVENTIONAL and is made up of conventional pollutants. Conventional pollutants are solid particles and matter found in our water. Most of the pollution you can see is conventional. Cans, bottles, paperjust about anythingcan be a conventional pollutant. You can see conventional pollutants in the picture above. Conventional pollutants cause a wide variety of environmental problems. The solids suspended in the water can block the sun's rays, and this blocking disrupts the carbon dioxide/oxygen conversion process. This process is vital to an aquatic food chain. Sometimes the solid pollution is so bad, the water becomes unusable to humans and animals. The best way to remove conventional pollutants is to run the water through a treatment plant. In treatment plants the water is skimmed, run through several filters, and settled. This removes about 60 percent of the pollutants. The remaining pollution is decomposed by tiny pollution-eating microorganisms. Microorganisms are living things that are so tiny you need a microscope to see them. Another type of pollution is called NON-CONVENTIONAL and is made up of non-conventional pollutants. Non-conventional pollutants are more dangerous to the environment than conventional pollutants. Non-conventional pollutants are dissolved metals, both toxic (harmful) and nontoxic (not harmful). Many factories dump these pollutants into the water as byproducts of their production process. The most devastating type of non-conventional pollution is an oil spill. More than 13,000 oil spills occur each year in the United States.

10. What Is Water Pollution? Although some kinds of water pollution can occur through natural processes, it is mostly a result of human activities. We use water daily in our homes and http://www.geocities.com/RainForest/5161/water1.htm

Everyone is against water pollution... but how does it happen, and how can it be prevented? Water is Essential for Life It covers 71% of the earth's surface and makes up 65 % of our bodies. Everyone wants clean water to drink, for recreation, and just to enjoy looking at. If water becomes polluted, its loses its value to us economically and aesthetically, and can become a threat to our health and to the survival of the fish living in it and the wildlife that depends on it. How does water pollution occur? Although some kinds of water pollution can occur through natural processes, it is mostly a result of human activities. We use water daily in our homes and industries, about 150 gallons per day per person in the United States. The water we use is taken from lakes and rivers, and from underground (groundwater); and after we have used it and contaminated it most of it returns to these locations. The used water of a community is called wastewater, or sewage. If it is not treated before being discharged into waterways, serious pollution is the result. Historically, it has taken humanity quite a bit of time to come to grips with this problem. Water pollution also occurs when rain water runoff from urban and industrial areas and from agricultural land and mining operations makes its way back to receiving waters (river, lake or ocean) and into the ground. What are some different types of water pollution?

Ecosystems: Wetlands General Resources Earth's Water Earth is the "watery planet". Viewed from space it is predominantly blue, as 74 % of its surface is covered by water. Oceans contain 97 % of the earth's water while the remaining 3 % is classified as freshwater. Seventy-seven percent of this surface freshwater is stored as ice and 22% as groundwater and soil moisture. The remaining freshwater, making up less than 1 % of the world total, is contained in lakes, rivers and wetlands.

Top of Page The Water Cycle The Water Cycle You may be familiar with how water is always cycling around, through, and above the Earth, continually changing from liquid water to water vapor to ice. One way to envision the water cycle is to follow a drip of water around as it moves on its way. I could really begin this story anywhere along the cycle, but I think the ocean is the best place to start, since that is where most of Earth's water is.

David A. Gillam, Susitna Elementary, Anchorage, AK WATER POLLUTION Appropriate for grades K-6. OVERVIEW: There are a wide variety of pollutants that can affect water and the plants and animals that live in the water. This pollution can be divided into three groups: chemical pollution, thermal pollution, and ecological pollution. Since not all pollution is human produced students need to understand that there are sometimes "natural" reasons for some pollution. PURPOSE: These activities will help students' understanding of water pollution and its potential effects on human and wildlife habitats. OBJECTIVES: Students will be able to: 1. Identify 2 or more pollutants in a bog, marsh, stream or other wetland area. 2. Relate a pollution prevention message through words and art. 3. Understand that some pollutants can not be seen. ACTIVITIES: 1. Taking student a wetland area helps them become more aware of the water around them. Take with you paper, pencils, clipboards, rubber gloves, plastic garbage bags and extra adults. When you get to your wetland site divide students into groups of 3 or 4. Each group is to look around the wetland area and find as many sources/types of pollution as possible. On their paper a designated recorder for each group will record the different types of pollution found. After 5-7 minutes, come together as a whole group and discuss the pollution that is seen. Since the visible pollution is often in the form of litter, discuss with your students the pollution that may be present, but not seen. When the group discussion is over, pass out gloves and bags. Divide students into groups and assign an adult to each group. Then have the students pick up the litter pollution and take back to school and put in dumpsters. Repeat throughout the year. 2. For this activity you will need paper, crayons, markers, crayon pastels and other art supplies. Review with the students the types of pollution that they know about. Talk about the ways people can help prevent certain kinds of water pollution. List them on the chalk board. Have students draw a picture showing how to prevent pollution of a wetland of other water source. Encourage students to think about the source of the pollution and ways to either prevent or ways to dispose of some pollutants. 3. To help students understand that clear water isn't necessarily free of pollutants, place 5 clear liquids in portion cups. Things to include should have a definite taste that students would recognize. Use sugar water, white vinegar, salt water, water mixed with citric acid, and tap water. Using cotton swabs, have students taste each liquid (dispose of swab after each taste) and record what they taste after each. After students have all had a chance to taste, discuss that some kinds of pollution can't be seen. If you have local creeks, streams, or other water ways that are unsafe for human use, this is a good jumping off point to discuss the problems these bodies of water have. RESOURCES/MATERIALS NEEDED: All resources are available in most areas. TYING IT ALL TOGETHER: Environment concerns can be understood by even the youngest school children. Providing them with a background of information and an opportunity to actively use that information, they will begin to develop a feeling of stewardship for their world. Using activities that develop environmental stewardship in students will hopefully become a basis for action in their future lives.

Water is necessary to life on earth. All organisms contain it; some live in it; some drink it. Plants and animals require water that is moderately pure, and they cannot survive if their water is loaded with toxic chemicals or harmful microorganisms. If severe, water pollution can kill large numbers of fish, birds, and other animals, in some cases killing all members of a species in an affected area. Pollution makes streams, lakes, and coastal waters unpleasant to look at, to smell, and to swim in. Fish and shellfish harvested from polluted waters may be unsafe to eat. People who ingest polluted water can become ill, and, with prolonged exposure, may develop cancers or bear children with birth defects.

Attention for water pollution exploded in the 1980s. The oil spill of the Exxon Valdez showed many around the world just how horrible the effects of water pollution could be. However, even the Exxon Valdez spill barely touched the surface of the problem of water pollution. The ship spilt only 5% of the oil spilt that year, and oil is just one of many pollutants that people dump into the water every year. Every year, 14 billions pounds of sewage, sludge, and garbage are dumped into the world's oceans. 19 trillion gallons of waste also enter the water annually. The problem of ocean pollution affects every nation around the world. This is especially true because water is able to transport pollution from one location to another. For many years, chemicals were dumped into bodies of water without concern. While many countries have now banned such behavior, it continues to go on today. As the world has industrialized and its population has grown, the problem of water pollution has intensified. The simple fact that millions of people live along coastlines and near rivers means that these bodies of water are likely candidates for heavy and destructive pollution. It is hard to know now what our oceans will look like in the future. Just how damaged they will be by pollution is uncertain.

20. WATER POLLUTION - Urban Fertilizers, pesticides, herbicides, pet and yard waste, motor oil, antifreeze, household hazardous wastes, and paint are just a few of the pollutants that http://www.cjnetworks.com/~sccdistrict/resubwt.htm

PREVENTING URBAN WATER POLLUTION TO MAIN MENU Slide Show The majority of people now live in cities. These urban environments are characterized by suburbs that contain many acres of hard surfaces. Natural vegetation such as forests and fields slow rainwater down, allowing it to soak into the surface. In contrast, streets, roofs, parking lots and manicured lawns, all provide hard, impervious, surfaces that prohibit rain from soaking into the ground. Since the excess rain water can not soak into the ground, it accumulates and rushes into storm sewers and waterways. There is a common misconception that water traveling into storm sewers ends up treated at the local wastewater treatment plant. Because of this misunderstanding, many citizens use storm drains and ditches as places to dispose of all kinds of pollutants . Thus, storm drains carry large amount of pollution away from urbanized areas mixed with the excess storm water. Street litter, fertilizers, pesticides, herbicides, pet and yard waste, motor oil, anti-freeze, household hazardous wastes, and paint are just a few of the pollutants that find their way into storm drains. This water travels from storm drains into local streams, ponds, and lakes, and ultimately into local streams and rivers. Because storm drains can be a major source of pollution to our waterways, it is important to keep polluting materials out of them.
