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

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

The opinion by Judge Marilyn Hall Patel finds that logging companies are required to obtain permits for pollution emitted from "ditches, culverts, channels, and gullies." This is the first court ruling in the nation to apply the Clean Water Act to this type of logging pollution and gives the go-ahead for the Environmental Protection Information Center (EPIC), represented by Earthjustice, to proceed with its case against the Pacific Lumber Company for pollution in Bear Creek, a tributary of the Eel River in Humboldt County, California. The U.S. EPA and the State Water Board have listed over 85 percent of the rivers and streams in the North Coast region, including Bear Creek and the Eel River, as "impaired" due to excessive levels of pollution caused by logging. The devastating effects of logging pollution on aquatic habitat are also the primary cause of reduced coho salmon and steelhead populations, which now require federal protection. Nevertheless, to date, little has been done by either U.S. EPA or California's North Coast Regional Water Quality Control Board to reduce or eliminate logging pollution on the

Water Pollution Sewage is a category encompassing human waste, garbage, and water used for laundering and bathing. About 80% of our sewage goes through treatment plans which remove nitrogenous and phosphorous compounds, as well as other solids. About 10% passes through septic tanks before being filtered and seeping into the ground. The remaining 10% remains untreated and passes directly into the water system. The three basic types of water contaminants are microbes, chemicals, and byproducts of decontamination processes. Microbes include viruses, bacteria, and intestinal parasites. The protozoan Cryptosporidium and the bacteria E. Coli, Giarda, and Salmonella are some common water-contaminating microorganisms. Diarrhea, dysentery, hepatitis, cholera, and typhoid fever, are some common bacterial diseases that can be found in drinking water. Hepatitis A, polio, and tuberculosis are some viral diseases found in drinking water. Recent Cryptosporidium outbreaks in Washington, D.C. and Milwaukee caused over 400,000 illnesses. Biological contaminants in the U.S. alone cause about 900,000 illnesses and kill about 900 people per year. Lead can leak into water from pipes and pipe solder. It can cause brain damage, especially in children. Iron and manganese can cause water to turn rust-colored. They are harmful when ingested in large amounts. Hydrogen sulfide gas gives water a rotten egg odor and is harmful in large concentrations. Radioactive substances, such as radium, can cause cancer, especially bone cancer. Nitrate compounds, which are found in fertilizers, prevent hemoglobin from binding with oxygen. Excess amounts can cause death in infants. Many organic compounds can pollute water. Examples of such chemicals are benzene, dioxin, MTBE (used widely as an anti knocking agent in gasoline), PCBs (polychlorinated biphenyls), fungicides, pesticides, and industrial chemicals.

Areas of Concern Non-native invasive species Urban sprawl TEACH Pollution Home Water pollution in the Great Lakes The pollution of our waterways became a national issue in June of 1969, the day that the Cuyahoga River, flowing through Cleveland, Ohio, on its way to Lake Erie, caught on fire because it was so polluted. Although this was not the first time that the Cuyahoga River had been in flames, the 1969 fire caught the attention of the nation and the fight began for increased water pollution controls, which eventually led to the Great Lakes Water Quality Act and Clean Water Act in the 1970s. Water pollution is defined as a change in the chemical, physical and biological health of a waterway due to human activity. Ways that humans have affected the quality of the Great Lakes water over the centuries include sewage disposal, toxic contamination through heavy metals and pesticides, overdevelopment of the water's edge, runoff from agriculture and urbanization, and air pollution.

GO TO.... Areas of Concern Non-native invasive species Urban sprawl TEACH Pollution Home Lake Erie: "We have met the enemy and he is us"* In the 1960s, Lake Erie was declared "dead," though, ironically, it was full of life just not the right kind. Eutrophication had claimed Lake Erie and excessive algae became the dominant plant species, covering beaches in slimy moss and killing off native aquatic species by soaking up all of the oxygen. The demise of Lake Erie even made it into a Dr. Seuss book, The Lorax Lake Erie is the shallowest and warmest of the five Great Lakes, and the basin is also intensively developed with agriculture, urban areas, industries and sewage treatment plants. For decades, pollution filled Lake Erie with far more nutrients than the lake could handle, with phosphorous being the main culprit. Phosphorous is a fertilizer that induces plant growth and algae and was also found in many commercial detergents at the time. Plants began growing, dying and decomposing in Lake Erie, creating anoxia (severe deficiency of oxygen) at the bottom of the lake and leaving the water's surface putrid and mossy. The lack of oxygen killed fish and other aquatic species, and the smelly surface repelled anglers, tourists and those living around Lake Erie. Heavy metals also had contaminated much of the fish population of Lake Erie. In response to public concern and recommendations by the International Joint Commission, the Great Lakes Water Quality Agreement was signed by the United States and Canada in 1972. The Agreement emphasized the reduction of phosphorous entering lakes Erie and Ontario, and in 1977 maximum levels for phosphorous were added to the Agreement. Also, phosphorus in detergents was finally banned. Coupled with the U.S. and Canadian Clean Water acts, the GLQWA did much to reduce the phosphorus levels in Lake Erie.
