Permits The Division of Water Pollution Control is responsible for administration of the Tennessee Water Quality Control Act of 1977 (T.C.A. 69-3-101). In addition, the Division is responsible for the non-coal surface mining program and illegal coal mining under the Tennessee Coal Surface Mining Law of 1980, as amended. On an annual basis, the Division monitors, analyzes, and reports on the quality of Tennessee's water. In addition, a number of specific surveys are conducted, including studies of in-stream biological communities and documentation of contaminant levels in sediment and fish flesh. The fish and bacteriological data generated by the Division are used by the Department to issue advisories to the public when levels of contaminants exceed those considered to be protective of public health. Numerous complaints and inquiries are investigated and responded to each year. Under the Water Quality Control Act, municipal, industrial and other discharges of wastewater must obtain a permit from the Division. Approximately, 1,700 permits have been issued under the federally delegated National Pollutant Discharge Elimination System (NPDES). These permits establish pollution control and monitoring requirements based on protection of designated uses through implementation of water quality standards and other applicable state and federal rules.

Though much has been done to clean up our waters, much work remains. Sewer overflows and runoff from farms and city streets threaten the life-sustaining properties of our waters, endanger human health and wildlife, and result in thousands of beach closings each year. NRDC works to continue reductions in industrial water pollution while pressing for effective pollution controls on agriculture, logging and other sources previously exempt from them. We help develop and promote strong federal laws and regulations to address polluted runoff, raw sewage discharges, and factory farm wastes and we sue polluters when they violate the Clean Water Act.

Water Pollution In Depth : Report Stormwater Strategies Community Responses to Runoff Pollution This May 1999 report from the Natural Resources Defense Council documents some of the most effective strategies being employed by communities around the country to control urban runoff pollution, which is among the top sources of water contamination in the country today. The collection of 100 case studies compiled and evaluated here is intended to serve as a guide for local decisionmakers, municipal officials, and environmental activists; it is also a resource for citizens concerned about the quality of their local environment. Added in October 2001 is a new chapter on low-impact development, which has emerged as a simple, effective and economical stormwater strategy that also carries a broader aesthetic appeal.

Introduction Tier I biomarkers Tier II biomarkers Biotransformation ... Conclusions Introduction In the attempt to define and measure the effects of pollutants on an ecosystem, biomarkers have attracted a great deal of interest. The principle behind the biomarker approach is the analysis of an organism's physiological or biochemical response to pollutant exposure. When compared with chemical residue analysis, biomarkers have an advantage of being a measure of the stress incurred in the organism, and so are more biologically relevant. However whereas chemical analysis for defined pollutants gives well defined concentration data, biomarkers are often more difficult to interpret. When compared with population parameters, the opposite is the case. Biomarkers are often more easily quantifiable than population parameters, such as growth and reproduction, but whereas measurements of population parameters gives an accurate picture of the ecological effects of the pollutant, biomarkers are not necessarily indicative of a deleterious effect. That is, although all population stresses are necessarily preceded by a biochemical response, all biochemical responses need not be associated with a population stress.

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.

37. 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.

GO TO.... 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.

Humans and other organisms produce bodily wastes which enter rivers lakes oceans and other surface waters ; in high concentrations these wastes result in bacterial contamination and excessive nutrient loading ( eutrophication ). Industries discharge a variety of compounds such as heavy metals , and wastewater , sometimes in toxic concentrations, from industrial process may also be too hot or too low in dissolved oxygen to support life. Silt -bearing runoff from construction sites and farms can inhibit the penetration of sunlight through the water column, hampering water organisms in their ability to photosynthesize Water pollution Groundwater pollution is more difficult to clean up than surface pollution because groundwater can move hundreds of miles through unseen aquifers .

The Lachine Canal , in Montreal , is badly polluted Water pollution Air pollution Pumping of highly toxic (dark black) sludge, much seeps back into the ocean in the form of tiny particles Early Soviet poster: The smoke of chimneys is the breath of Soviet Russia Pollution is the release of harmful environmental contaminants, or the substances so released. Generally the process needs to result from human activity to be regarded as pollution. Even relatively benign products of human activity are liable to be regarded as pollution, if they precipitate negative effects later on. The nitrogen oxides produced by industry are often referred to as pollution, for example, although the substances themselves are not harmful. In fact, it is solar energy (sunlight) that converts these compounds to smog Pollution can take two major forms: local pollution and global pollution. In the past, only local pollution was thought to be a problem. For example, coal burning produces smoke , which in sufficient concentrations can be a health hazard. One slogan, taught in schools, was "The solution to pollution is dilution." The theory was that sufficiently diluted pollution could cause no damage. In recent decades, awareness has been rising that some forms of pollution pose a global problem. For example, human activity (primarily
