Water Pollution/ Water Monitoring

Back to top
For a general introduction to the topic, the Wikipedia page on water pollution is a good starting point.

The UK Rivers Network is an organization which aims to draw attention to problems with rivers in the UK and to campaign for solutions. It has its own introductory page to the subject, as well as many more links to information and news articles about water pollution and rivers, including "Finding out about water pollution."

Your Online Guide To Water Pollution, a site recommended to me by a teacher, has a wealth of information and resources on the various facets of water pollution. It is organized in terms of types, causes, sources, and control methods, with links to numerous web sites-- mostly of government agencies which have to deal with the problems.

Stream Biology and Ecology is a very readable, well organized introduction to the life forms that inhabit streams and rivers, how they interact with each other and the environment, and the negative impact that human activities can have on them.

The city of Boulder, Colorado hosts a page which provides an introduction to a number of individual water quality parameters, the problems they can cause, and how they are measured.

This pdf document, from a study of the lakes in Tallahassee, Florida, gives a good explanation of the biological, physical, and chemical parameters which are monitored in a water quality study.

The Water Pollution Guide contains useful information about the sources of water pollution and the potential dangers it causes. It also gives a number of tips on preventing it and ways to help keep our waters clean. This is one of a series from the UK-based Guides Network

While much progress has been made in the US to prevent pollution from "point sources", such as industries and municipal wastewater treatment plants, approximately 40 percent of our surveyed rivers, lakes, and estuaries still are not clean enough to meet basic uses such as fishing or swimming, according to a fact sheet published by the U.S. Environmental Protection Agency (USEPA). Agriculture, forestry, grazing, septic systems, recreational boating, urban stormwater runoff, and construction are potential sources of "non-point source" (NPS) pollution. Careless or uninformed household management also contributes to NPS pollution problems. The EPA's Office of Water has a redesigned page about the problem of non-point sources. There is a lot of information for students and educators, and tips on what you can do to help.

The National Water Quality Inventory Report to Congress (305(b) report) is the primary vehicle for informing Congress and the public about general water quality conditions in the United States. This document characterizes our water quality, identifies widespread water quality problems of national significance, and describes various programs implemented to restore and protect our waters. The reports from 1992 through 2004, as well as the 2002 National Assessment Database are available. A summary of the findings of the 2000 report can be found in Oct. 1 issue of the EPA newsletter WaterNews.
See below for a booklet published in May 2001 which presents the key findings from the 1998 report in a format for children.
Click for an update January 27, 2009.

For a clear and thorough description of how runoff from agriculture causes water pollution, go to the USEPA's site which features the draft guidance manual, National Management Measures to Control Nonpoint Source Pollution from Agriculture, and click on Chapter 2. (It is a 108k pdf file, which requires the free Adobe Acrobat Reader plugin)

The EPA's approach involves determining the "total maximum daily loads" (TMDL) of various pollutants a waterway can handle without deterioration of its water quality. A thorough, readable introduction to this subject is available as a free download in pdf format from YSI, Inc., a company which makes water monitoring equipment. [Note: free registration with YSI is required to download this particular file.] Click on Download the paper, "Getting Started with TMDL's". Pages 23-35 (pages 33 -45 of the pdf file) provide an excellent introductory discussion of the common types of water pollutants, their effects, and interactions. I highly recommend it. [If that direct link does not work, go to their home page, choose "environmental", then "applications", then "surface water", then "Getting Started with TMDL's".]

One of the most important reasons for preventing water pollution is that leads to contamination of our drinking water sources. The Safe Drinking Water Act in the U.S. became law in 1974. The USEPA's Office of Groundwater and Drinking Water set up a web site on its 25th anniversary in 1999 to commemorate the occasion. The site is regularly updated. You will find many fact sheets (in PDF format) for "Kids and Teachers" at all grade levels, an Information Kit, and discussions of future needs. There is an emphasis on protection of our water resources.
For more consumer and educational information about drinking water, see the American Water Works Association (AWWA) Consumer Water Center page.

The USEPA has a page about water quality monitoring, including volunteer monitoring programs, with issues of a semi-annual newsletter dating back to 1993 available for on-line reading. Their publication, Volunteer Stream Monitoring: A Methods Manual (EPA 841-B-97-003), formerly available only in print, can now also be accessed on line. The publication, Volunteer Estuary Monitoring, A METHODS MANUAL, is now available, as well.
"[T]he presence, condition, and numbers of the types of fish, insects, algae, and plants can provide accurate information about the health of a specific river, stream, lake, wetland, or estuary." The EPA site Biological Indicators of Watershed Health provides an educational introduction to the subject, including the types of species used, the design of a sampling effort, specimen collection, and data analysis. Many links are provided for more detailed study.
(See below for links to sites where volunteer monitors can learn to identify macroinvertebrates found in ponds and streams.)
The EPA also has a page which lists volunteer monitoring programs by name or by state. There is a great deal of information available about each program. If you or your organization runs such a program, you can add it to the list, and update the information at any time.
The U.S. Environmental Protection Agency partnered with America’s Clean Water Foundation and the International Water Association to urge people around the world to test the quality of their streams, lakes, wetlands, and coastal waters. The first World Water Monitoring Day was held Oct. 18, 2003. Volunteers of all ages performed four key tests to measure dissolved oxygen, pH, turbidity/clarity and temperature, and could then enter their findings on the Web. Test kits were available through America’s Clean Water Foundation.

The Waterwatch network in Australia consists of over 3000 volunteer monitoring groups made up of individuals, community groups and school groups who undertake a variety of biological & habitat assessments and physical & chemical tests to build up a picture of the health of their waterways and catchments. Their library page includes a technical manual which explains the significance of various parameters and the methods for measuring them. Check out the links page, as well.

Girl Scouts in the U.S. can now earn a Water Drop patch through a collaborative effort with the USEPA. The project includes twenty different watershed activities in which Girl Scouts can get involved. To assist with the program, EPA published a Water Drop Patch Project booklet with detailed background information on watersheds, polluted runoff, wetlands, groundwater, and drinking water.
See also the EPA's "Linking Girls to the Land" page with a link to a new brochure on Girl Scouts and World Water Monitoring Day – October 18, 2005

The USEPA has prepared a simple introduction to the problem of contaminated sediments, which result from pollutants which settle to the bottom of a water body. They discuss the sources and types of materials, as well as the consequences for the wildlife and for human health.

An advocacy group which focuses on environmental issues as well as other topics, the U.S. Public Interest Research Group (P.I.R.G.), has published a reports in recent years about toxic releases into America’s waterways based on the publicly available information which must be submitted by industries to the US EPA as "Toxic Release Inventories" under the national "right-to-know" laws. These reports can be accessed through their State PIRG Publications and Reports page. [Note: This page was not available as of March 24, 2002, but a search for http://www.PIRG.org/reports/index.htm at www.google.com will allow you to view their cached version of this page.] You can also access this information directly and learn more about the program at the EPA's TRI web page.

[Contamination of the sediments in a river by toxic organic chemicals is an issue that is very close to home in the Berkshires. The Housatonic River, into which our treatment plant discharges, has been heavily contaminated by PCB's (polychlorinated biphenyls) from the former manufacture of large electrical transformers at a facility upstream. Click here to see some photos I took of how the contamination is being dealt with. Note:-- New photos added November, 2003. For extensive coverage with many more pictures, go to the EPA Region 1 GE Housatonic River website. The site also describes the various remediation projects to be undertaken as spelled out in a Consent Decree lodged Oct. 7, 1999 in U.S. District Court in Springfield, MA. The Housatonic River Initiative, a local advocacy group which has been instrumental in promoting the cleanup, also has a web site about the various problems involved.
Note: The Housatonic made the list of America's Most Endangered Rivers of 2004. See above.
Learn more about the chemistry of PCB's, the risks to human health and the environment and the contamination in the nearby Hudson River (New York,USA), as well, with links to sites about other contaminated waterways. EPA region 8 also has a site with information about PCB's.

The oceans may be vast, but water pollution originating from the watersheds on land has negative impacts on beaches, estuaries, coral reefs, and near-coastal waters. The USEPA has a series of on-line brochures that introduce the problems, what the EPA is doing about them, and what you can do, as well. Similar impacts on fresh water bodies are discussed, also.
Since 1991, the U.S.-based environmental advocacy group, the Natural Resources Defense Council (NRDC), has been publishing reports about incidents of beach pollution, including state-by-state information. The latest version has chapters with background information on sources of beach pollution, as well as the health effects and economic impacts. The EPA also has a BEACH Watch site with local beach information and reports.
The U.S. National Oceanic and Atmospheric Administration (NOAA) has a site about spills of oil and toxic chemicals, how they are controlled, and how coastal areas are restored. The site has many educational resources, including photos of major oil spills, explanations of treatment methods with diagrams, a kids' page with experiments and help for writing school reports, and even training manuals and software for spill responders.

The United Nations Environmental Program's "Global Programme of Action for the Protection of the Marine Environment from Land-based Activities"(GPA) site states that "The major threats to the health, productivity and biodiversity of the marine environment result from human activities on land - in coastal areas and further inland. Some 80% of the pollution load in the oceans originates from land-based activities. This includes municipal, industrial and agricultural wastes and run-off, as well as atmospheric deposition... The GPA is designed to be a source of conceptual and practical guidance to be drawn upon by national and/or regional authorities for devising and implementing sustained action to prevent, reduce, control and/or eliminate marine degradation from land-based activities." You will find a wealth of information and links here concerning the sources and effects of pollutants and efforts needed to mitigate them. A 4.39 minute video is also viewable at the site.

There were news stories a while back about an outbreak of a disease which was killing fish in the Chesapeake Bay area of Maryland and Virginia. Humans also suffered strange neurological effects from a toxin produced by the microorganism responsible. Some experts feel that excessive nutrient runoff from chicken and hog farming may have been to blame for the rapid growth of the pathogens. The situation had a negative impact on the fishing industry in the area. Learn about Pfiesteria piscicida at this site from the U.S. Department of Agriculture (USDA) and this site from the state of Maryland Dept. of Natural Resources.

One of the links, Water What-If's, including a table of warning signs of pollution, as well as lessons on the topics of pH, temperature, dissolved oxygen, nitrates/phosphates, and macroinvertebrate surveys, along with instructions for test kit use.

The Yarra Valley Water company, which serves the Melbourne, Australia, area, has an educational web site that should be bookmarked by anyone involved in teaching about environmental science at the primary or middle school level (grades 1 - 7). Topics include the nature of water, the water cycle, water pollution and conservation, and water and wastewater treatment processes-- including plant tours and diagrams. The pages with illustrated descriptions of the plants and animals found in freshwater ponds are very informative. There are also links and other resources for teachers. You can also get there from their main site by clicking on "Education" on the left side of the page.

The Spring `99 Issue of the EPA Volunteer Monitor has a feature called "Bugs in the Web!" which has links to two websites which offer "macroinvertebrate descriptions and drawings specifically aimed at volunteer monitors. Volunteer groups are welcome to `steal' these materials for use in their own manuals and brochures." 1)The Field Guide to Freshwater Invertebrates, prepared by Leska S. Fore and illustrated by Annabel Wildrick. The drawings can be downloaded in GIF format and opened in a word processing or drawing program. 2)The second site that is "full of bugs" is Major Stream Invertebrates.

Students in a fifth grade class have told their teacher that they really like the following environmental and science resources and want me to share them with you.  What better recommendation could there be?  There is a lot to see and learn from on these web sites. :
Water Conservation for Kids
RecycleWork - Kid's Sections
Energy Kids (U.S. Dept. of Energy)

Wastewater Operations Training and Practice Certification Tests
Online Courses: Students can obtain an Associate degree in Environmental Science, with a specialization in water/wastewater, entirely on the web through Mountain Empire Community College, a part of the Virginia Community College System. In addition, anyone can access course materials, some with self-grading practice tests, from the Subjects & Courses page. Or access some of the tests directly.

[Advanced Distance Learning Environmental Engineering courses are available from Worcester Polytechnic Institute (Worcester, Mass., USA)]

Print-based training: The Office of Water Programs at the California State University, Sacramento (CSUS) College of Engineering and Computer Science provides distance learning courses for persons interested in the operation and maintenance of drinking water and wastewater facilities. These training programs were developed for the U.S. Environmental Protection Agency... Course manuals are available alone, or can be purchased as credit courses for CEU's which may be accepted as training by many state departments of environmental protection.

Practice wastewater and laboratory certification tests can be taken at the Water Environment Federation's SkillsBuilder site available at at their SkillsBuilder page. "The SkillsBuilder is a FREE, easy-to-use and confidential way to test your knowledge, sharpen your test-taking skills, and practice those pesky math calculations."
On their Training Products page they offer a variety of training materials for certification preparation - workbooks, study guides, training manuals, and CD-ROM courses.

A large collection of wastewater exam questions with answers can be found at Eric Schiff's exam page

The Pennsylvania Dept. of Environmental Protection has a pagewith several practice quizzes for wastewater and drinking water certification.
