Publications library Nitrate levels in many English waters, both ground and surface waters, are increasing. Nitrate pollution is of concern because it has to be removed before water can be supplied to consumers, and it can harm the water environment. Over 70% of nitrate enters water from agricultural land. The following pages provide details of action to reduce agricultural nitrate pollution, which is one aspect of the broader problem of diffuse pollution from agriculture. We are also taking action to reduce similar pollution from other sources. For example, the Urban Waste Water Treatment Directive aims to reduce pollution, including nitrate pollution, from sewage treatment works and industry.

What Is Water Pollution? depends on it. How does water pollution occur? Although some kinds How do we prevent water pollution? To keep our used water from http://www.geocities.com/RainForest/5161/water1.htm
Extractions: Everyone is against water pollution... but how does it happen, and how can it be prevented? 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. 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?

Extractions: 1120 19th Street, N.W., Suite 550, Washington, D.C. 20036 . . . (202) 659-1833 Previous Section Table of Contents Glossary Next Section Pollution and Disease Deteriorating water quality is a particular threat in developing countries, where hundreds of millions of people lack access to clean drinking water and the vast majority of sewage is discharged into surface waters without wastewater treatment. In many urban areas in poorer countries people compete for access to polluted water to satisfy their drinking needs. In 1980, 1.8 billion people lacked access to clean drinking water and a 1.7 billion lacked access to adequate sanitation services. The United Nations declared the 1980s the Drinking Water Supply and Sanitation Decade, and the next 10 years saw 1.3 billion people supplied with new water sources and 750 million with sanitation. Yet at the end of the decade, 1-2 billion people still lacked safe water and 1.7 billion lacked sanitation services. The UN estimated in 1990 that population growth alone would add nearly 900 million people to these categories in the coming decade, with investments in infrastructure unlikely to keep pace. In many developing countries, river pollution from raw sewage reaches levels thousands of times higher than the recommended safe limits for drinking and bathing.

Teacher S Guide Teacher s Guide Effects of water pollution on Plants. Overview Students Purpose To see if pollution in water will affect plants. Hypothesis http://www.msnucleus.org/watersheds/tule/plantstguid.html
Extractions: Effects of Water Pollution on Plants Students will perform an experiment in which they will observe how water pollution is absorbed into plants. Only pure water is evaporated, while other substances are left behind. As a result these impurities become part of the water system. All water eventually flows to the oceans. In Fremont, water flows into the San Francisco Bay through a series of creeks and sloughs. Waters running off the west side of the Fremont section of the Diablo Range fill creeks all along the mountain side. These stream waters are joined by waters flowing through city storm drains as well as water run-off from the various farmlands around Fremont. Run-off water may drop into Tyson Lagoon or Lake Elizabeth along the way. The streams enter the bay through the Alameda Flood Channel, Newark Slough, Plummer Creek, Mowry Slough and Mud Slough. Pollution anywhere along this pathway will find its way into the bay. Plants, animals, and microorganisms are all affected by pollution found in the creeks and ponds along the pathway to the bay. Below is information that will help you prepare and conduct the experiment on water pollution. Read all the information before beginning the experiment with your class. The
Rivers There are several sources of water pollution which work together to reduce overall river water quality. Other sources of water pollution. http://www.wildlifetrust.org.uk/facts/rivers.htm
Extractions: Rivers and the surrounding land drained by them (catchments) are very important wildlife habitats. The water itself provides the environment for fish, plants and animals, while the banks and nearby land support creatures such as otters, kingfishers and dragonflies and a variety of water-loving plants. Between 1985 and 1990 there was a decrease in the total length of rivers and canals in England and Wales having top quality water. Meanwhile the total length of 'poor' quality waterways increased. Since 1990 the situation in England and Wales has improved. The Environment Agency reports an increase in length in the best quality grades of waterway and a reduction in the poorest. Indeed there has been significant improvement in 10.7% of the total length of rivers and canals in England and Wales. Where does pollution come from? There are several sources of water pollution which work together to reduce overall river water quality. Industry and agriculture discharge liquid waste products. Rain as it falls through the air, or drains from urban areas and farmland, absorbs contaminants. Serious incidents resulting from spillages or discharges of toxic chemicals are the pollution events that make the news. For example, just one litre of insecticide killed over 1,000 fish in the River Glaven in Norfolk. The impact of a slow build-up of pollution over a long time and in a wide area can be even more serious. During the 1950s, otters in many parts of the country were nearly wiped out by the accumulation of pesticides in our rivers
San Jose/Santa Clara Water Pollution Control Plant San Jose / Santa Clara water pollution Control Plant. The water pollution Control Plant has the capacity to treat 167,000,000 gallons of wastewater per day. http://www.ci.san-jose.ca.us/esd/wpcp.htm
Extractions: Water Pollution Control Plant About the Plant The San Jose/Santa Clara Water Pollution Control Plant is one of the largest advanced wastewater treatment facilities in California. It treats and cleans the wastewater of over 1,500,000 people that live and work in the 300-square mile area encompassing San Jose, Santa Clara, Milpitas, Campbell, Cupertino, Los Gatos, Saratoga, and Monte Sereno. The Water Pollution Control Plant has the capacity to treat 167,000,000 gallons of wastewater per day. It is located in Alviso, at the southernmost tip of the San Francisco Bay. Originally constructed in 1956, the Plant had the capacity to treat 36,000,000 gallons of water per day and only provided primary treatment. In 1964, the Plant added a secondary treatment process to its system. In 1979, the Plant upgraded its wastewater treatment process to an advanced, tertiary system. Wastewater from sinks, toilets, and drains inside homes, businesses and schools in most of Santa Clara Valley travels through an underground pipe system, known as the sanitary sewer system, before it arrives for treatment at the San Jose/Santa Clara Water Pollution Control Plant. That journey can take up to 10 hours. About 18 hours later, 99% of the impurities have been removed through a highly sophisticated treatment process that simulates the way nature purifies water, but at a greatly accelerated rate.
Extractions: 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.
About Pulp Pollution And Making Clean Paper Information resource for environmentalists, consumers and paper mills on the polluting impact on air, ground and water of pulp and papermaking processes. Extensive links to technical information and environmental action sites. From Reach for Unbleached!, a Canadian charity. http://www.rfu.org/AboutPulp.htm
Extractions: Pulp and paper mills pollute our water, air, and soil. The pulp and paper industry is one of the largest and most polluting industries in the world; it is the third most polluting industry in North America. There are about 500 kraft mills, and many thousands of other types of pulp and paper mills, in the world. Primary concerns include the use of chlorine-based bleaches and resultant toxic emissions to air, water, and soil. With global annual growth forecast at 2.5%, the industry and its negative impacts could double by 2025. People need paper products, but we also need sustainable, environmentally safe production Why Does Pulp Pollution Matter? Pulp and paper is the third largest industrial polluter to air, water, and land in both Canada and the United States, and releases well over a hundred million kg of toxic pollution each year (National Pollutant Release Inventory, 1996). Making paper also consumes vast quantities of trees Water Pollution Pulp mills are voracious water users. Their consumption of fresh water can seriously harm habitat near mills, reduce water levels necessary for fish, and alter water temperature, a critical environmental factor for fish. Mill owners say they are unable to institute water conservation and recycling because the concentrated effluent would kill fish (British Columbia COFI Pollution Prevention Workshop, June 1997, Environment Canada PPER Consultations, June 2000).
AMSA - Association Of Metropolitan Sewerage Agencies Has current news and information about clean water issues (such as nonpoint source pollution and radioactivity in municipal wastewater), as well as resources for POTW operators. http://www.amsa-cleanwater.org/
Extractions: AMSA met last week with key minority staff on the House Transportation and Infrastructure Committee to discuss the need for the House's support of the $958 million set aside for stormwater mitigation projects that the Senate passed as part of its Safe, Affordable, Flexible and Efficient Transportation Equity Act ( SAFETEA ), S. 1072. Given the problems that some publicly owned treatment works (POTWs) are encountering with their Total Hydrocarbon (THC)/Carbon Monoxide (CO) - Continuous Emissions Monitoring Systems (CEMS) and the differing interpretations of the 40 CFR Part 503 requirements concerning THC/CO-CEMS, AMSA and the Water Environment Research Foundation ( WERF ) are conducting a joint survey to collect information on the issues surrounding biosolids incineration.
