(Photo: AP) "Not too far off, though, this technology will be able to serve as an early warning system, a network of robotic sentinels, to protect our waterways from terrorist attacks." Steven Effler Upstate Freshwater Institute (AP) A network of underwater robots beaming up a near real-time environmental profile of lakes, rivers and reservoirs could soon be on the prowl helping safeguard the United States' drinking water from sabotage. The robots would replace researchers who painstakingly collect water samples in bottles and take them back to the laboratory for analysis, an expensive, time-consuming and sometimes dangerous practice. By summer 2005, Syracuse University researchers will have installed a dozen robotic sensors to form the largest underwater monitoring system of its kind in the country and one of the most extensive in the world, said principal investigator Charles Driscoll, a professor of environmental systems engineering at Syracuse. The project will cover more than 25 miles of the Seneca River and five connected lakes, including three municipal drinking water sources for more than 500,000 people in central New York.

Where Do You Get Your Drinking Water? Private and Public Systems County citizens receive potable water from a variety of sources. These sources are classified as either private or public water systems. Private water systems serve only a single connection and usually consist of a well used for a single home. There are approximately 12,000 private water systems in King County. Public water systems contain more than one connection. The public systems are managed by homeowners; private, non-profit organizations and corporations such as homeowners' associations; private, for-profit companies; municipalities such as cities and water districts. Public water systems are further classified by size. A public water system is classified as a Group B system if, in general, it serves from 2 to 14 connections. About 1,700 Group B public water systems currently operate in King County. In general, a Group A system serves 15 or more connections. There are 217 Group A public water systems in the county. There are also other characteristics that differentiate Group A and Group B systems.

Water Quality Initiative Bacteria in Drinking Water Reviewed and adapted for Missouri by Wanda Eubank, Jerry D. Carpenter and Beverly A. Maltsberger, University of Missouri-Columbia, and Nix Anderson, Missouri Department of Health, from Bacteria in Drinking Water by Karen Mancl, Water Quality Specialist, The Ohio State University. Can bacteria in water make me sick? The transmission of disease through drinking water is one of the primary concerns for a safe water supply. Human illnesses such as typhoid, dysentery, cholera, hepatitis and giardiasis have been linked to drinking water contaminated by human waste. Can bacteria in water affect livestock? Bacteria levels for livestock vary with intended water use (see Table 1). Adult animals are more tolerant of bacteria than young animals. Water for cleaning and sanitizing must be of very high quality to prevent infections and contamination of food products. Table 1. Bacteria guidelines for livestock water supplies. Adult animals 1,000 fecal coliforms/100 ml Young animals 1 fecal coliform/100 ml Dairy wash water 1 coliform/100 ml How to tell if water is contaminated with bacteria Testing a water supply for specific disease-causing organisms is expensive. Handling and culturing disease organisms requires special training and equipment. Also, if the water supply is being contaminated by human wastes, but the disease organism is not present the day a sample is taken, the risk of future exposure to the illness is still present.

Definitions - Common Terms About Wells and Ground Water Introduction If your family gets drinking water from your own well, do you know if your water is safe to drink? What health risks could you and your family face? Where can you go for help or advice? This pamphlet helps answer these questions. It gives you general information about drinking water from home wells (also considered private drinking water sources). It describes types of activities in your area that can create threats to your water supply. It also describes problems to look for and offers maintenance suggestions. Sources for more information and help are also listed. All of us need clean water to drink. We can go for weeks without food, but only days without water. Contaminated water can be a threat to anyone's health, but especially to young children. About 15 percent of Americans have their own sources of drinking water, such as wells, cisterns, and springs. Unlike public drinking water systems serving many people, they do not have experts regularly checking the water's source and its quality before it is sent through pipes to the community.

David dives in to see how we make water safe to drink. Segment Length: 6:30 Teacher's Guides Index Drinking Water Show Number 1413 How do we get the impurities out of drinking water? Where does drinking water come from? Getting Started Water has been called the universal solvent because it can dissolve just about anything over time. How does the solubility of water change with temperature? See how much salt you can dissolve in equal volumes of water at different temperatures. How can you use your test results to make predictions about water solubility around the world? Overview Each day, millions of Americans use billions of gallons of water without knowing where it comes from or what might be in it. As populations grow, the combination of increased demand and increased pollution means many of us are using sources of water that are less than pristine. Contamination from sediment , bacteria, protozoans , heavy metals, and synthetic organic compounds shows up with alarming frequency. As a result, many municipalities are having to pre-treat drinking water. The first step in most municipal treatment systems involves gravity. If you've ever let a glass of chocolate milk stand for any length of time, you've probably noticed that much of the chocolate settles to the bottom of the glass. The same is true of sediment in water. When the water is allowed to stand in large pools, many of these suspended particles simply settle to the bottom where they are collected and disposed of.

Press Release Description The U.S. Environmental Protection Agency (EPA) has been considering a more stringent regulation of arsenic in water. A significant reduction in the maximum contaminant level (MCL) could increase compliance costs for water utilities. This book discusses the adequacy of the current EPA MCL for protecting human health in the context of stated EPA policy and provides an unbiased scientific basis for deriving the arsenic standard for drinking water and surface water. Arsenic in Drinking Water evaluates epidemiological data on the carcinogenic and noncarcinogenic health effects of arsenic exposure of Taiwanese populations and compares those effects with the effects of arsenic exposure demonstrated in other countries—including the United States.
