( Keywords are "water quality," "water treatment," "wastewater treatment," "water pollution," "domestic," "industrial," "agricultural." )

A short summary of why water quality is important and common sources of pollution. Includes links to information on Point Sources, Environmental Quality Standards, Groundwater, Water industry planning, and other topics.

Extensive overview of household water and water problems such as hard water, water smells and water stains, water filtration and water testing.  Includes a link to the possible health effects of water contaminants.

A poster-sized illustration detailing the cycle of water use with emphasis on pollution.

A timeline of the major events in the history of drinking water from the Egyptians until modern times.  Includes links to the Story of Drinking Water and Fact Sheets.

See above.

Just what the title says.  

These databases are very specific and statistically detailed.  For example: ChemFinder.

Links include Introduction Septic tank/soil absorption system, Quantity of wastewater, Consider the following ways to minimize water use, Quality of wastewater, Consider the following ways to improve wastewater quality, Collection of wastewater, Preteatment System, Disposal of wastewater and pumpage.

Material covers: Septic tanks/soil absorption systems, Quantity of wastewater, Quality of wastewater, Collection of wastewater, Treatment systems, Disposal system, Assistance with failing systems or new designs, and an Evaluation table.

A simple page by the EPA which explains the cycle of water use.  There is a simple diagram as well. Includes a link to Ground Water & Drinking Water which in turn has several more links at the EPA.

This site is set up like an encyclopedia of water treatment with sections devoted to Introduction, Water Treatment Plants, Coagulation and Flocculation, Sedimentation and Separation, Filtration, Disinfection, Miscellaneous Treatment Processes, Sludge Handling and Disposal, Legal Aspects, and Distribution Systems.

This is a huge poster-sized diagram of a municipal water treatment cycle.

A very nice overview of water treatment and water treatment regulation.  This information is from the Ohio State University Extension office.

An impressive graphic showing the different steps taken in water treatment.

Everything you might want to know about septic systems.  Includes the following sections:  Septic Tank Location, Sizing and Septic Tank Construction, Installation Septic Tank Outlet Pipe, Distribution Box, Absorption Field Location, Absorption Field Size and Construction, and Maintenance.

A virtual tour of an actual sewage treatment plant.  There are links to explain the various steps in the process as well.

This site is from the University of California, Berkeley.  It covers the means that should be used to properly dispose of chemicals used at the university.  It has a very complete list of chemicals that are Class A chemicals (low hazard), Class B chemicals (moderate hazard), and Class C chemicals (high hazard).

A very complete website.  There is a simple diagram on the first page which allows you to click on any stage of the water treatment process for a detailed explanation.  At each level there a full color photos of actual equipment currently used to treat water.

 

 

 

 

 

 

 

 

 

This site is from an online geography course.  It is an overview of water pollution with all vocabulary linked to definitions of terms.  If you are not too sure of the terms used in discussions of water quality and water treatment, this is a good starting place.

A simple overview with some tips offered for avoiding polluting groundwater.

A huge website from the state of Texas.  Links included are Reducing Contamination by Improving Wellhead Management and Conditions, Reducing Contamination by Improving Pesticide Storage and Handling, Reducing Contamination by Improving Fertilizer Storage and Handling, Reducing Contamination by Improving Petroleum Product Storage, Reducing Contamination by Improving Hazardous Waste Management, Reducing Contamination by Improving Household Wastewater Treatment, Reducing Contamination by Improving Livestock Manure Storage and Treatment Facilities, Reducing Contamination by Improving Livestock Holding Pen Management, Reducing Contamination by Improving Milking Center Wastewater Treatment, Well Closing Slide Set. 

A very basic overview of water use.

Again, a very basic overview.

Short videos covering the following topics: Introduction to TEX*A*Syst, Pesticide and Fertilizer Storage, Petroleum Product Storage, Household Hazardous Waste and Septic System, and Livestock Waste Management.

This is pretty much what the title states it is, a site which takes you step by step through the process calculating the water quality of water found in your local watershed area.  Each step includes links to government data and simple graphics showing you how to work through the data.

This is a really nice starting place for your investigation of water and water quality.  If this site were to be printed out, it would run about four pages and it contains some interesting graphics as well.  Not too complicated, and not too simplistic either.

This website is similar to the one you are using right now.  There are links with one and two sentence annotations.  Sections include General Resources, All About Water, The Water Cycle, Ground Water, Water in Your Life, Treatment of Polluted Water, Rivers and Lakes of Canada
Teacher Resources, Ecosystems: Wetlands.

Contains some good charts and graphs.  Includes links to point-source pollution, non-point-source pollution, toxics, runoff from urban streets, agricultural lands.
