Water represents an essential ingredient of life and health. Maintaining the supply of water in sufficient quality and quantity to protect health and quality of life has been a community responsibility since the earliest human settlements. Storing and moving water as needed was the technological turning point in the growth of cities, as marked historically by the Roman aqueducts. Having achieved remarkable success in controlling organic pollutants in water supplies, the challenge today is increasingly with inorganic pollutants. Our overall objective for this chapter is to imbue the an appreciation of the continuing vigilance required in controlling the quality of water while ensuring its equitable distribution and appropriate use for recreational, agricultural and industrial purposes. This balance requires skill in the management of both water and wastes.
The social importance of water to the survival and economy of communities sets the stage for this chapter. The epidemiology of infectious and toxic agents in water examines the distribution and trends in risks, water consumption and water sources. Sections on regulation and testing of water includes the latest development and uses of chlorine and other tests, safe drinking water legislation and current controversies. The contrasting issues confronting developing countries highlight the severe problems of safe water supply in some parts of the world. The remainder of the chapter addresses the issues and technologies of community waste management, including sewage, chemical wastes and solid wastes.

Low-Cost Water Stabilization Prevents Water Pipe Corrosion.(Mail and Guardian, 12 February 1999. Scientists from Environmentek at the South African Council for Scientific and Industrial Research (CSIR) have developed a low-cost, water-stabilization system using limestone instead of conventional lime to neutralize corrosive water. Some 40% of South Africa's water is soft and acidic and pipe maintenance and repair due to corrosion is one of the hidden costs in water distribution. Stabilization systems were developed in three sizes for different users.: mailto:email@example.com)
Canada Wants Ban on Water Exports. (Environment News Service, 11 February 1999). The Canadian government has announced a new federal strategy to prohibit bulk exports of fresh water (excluding bottled water). It calls on provinces to declare a moratorium on large-scale water diversions and sales until a broader, national accord aimed at protecting Canadian watersheds can be put in place. The announcement comes after several recent business proposals to export water from Canada had raised alarms. The United States and Canadian federal governments have asked the International Joint Commission (IJC) to examine the use, diversion and removal of waters, including removals in bulk for export, along the common border. Canada has about 9% of the world's renewable water resources and 20% of the world's total freshwater resources. mailto:firstname.lastname@example.org
EPA May Change Lead Paint Rules
EPA May Change Lead Paint Rules. WASHINGTON (AP, Feb. 17, 1999) - It's called the Alliance for Safe and Responsible Lead Abatement. Its target audience is Americans concerned about the environment. And its stated goal is to protect drinking water from being poisoned by lead paint removed from older homes and apartment buildings. But behind the alliance's efforts is a $50-million-a-year industry whose specialized service would be jeopardized by an Environmental Protection Agency proposal. The EPA wants to drop federal rules requiring that certain steps be taken to contain building debris contaminated with lead paint. Instead, the agency would let contractors dump the material in landfills. The lead abatement industry says that could result in drinking water contaminated with lead, which is especially harmful to children.
World Water Day 1999: Everyone Lives Downstream. Excessive floods in 1998 have resulted in thousands of deaths and caused enormous damage in China, Bangladesh, and India, where nearly half of the world population lives. They are not only the result of excessive rains, but also of interference by mankind in the river basins. These tragedies make us realize that virtually everybody in this world lives downstream, which is the theme of the 1999 World Water Day on 22 March. Background materials and further information on World Water Day are available at: http://www.irc.nl/products/advocacy/wwd/wwd99.html
India, New Delhi: Clean Capital Drive INDIAN EXPRESS, Feb. 20, 1999. The Delhi government has launched a month-long "Clean-the-Capital" drive from 1 March 1999 to coincide with 'Visit India Year'. With the support of NGOs, welfare associations and the public, it aims to improve sanitation in the Capital. Special cells would be opened where people could register complaints against the municipal authorities. The focus will be on 100 colonies where garbage-collecting trucks go door to door. At present 5,800-6,000 metric tonnes of garbage is collected in a day. The government also prepared a 'module' on community involvement in garbage collection.

Acid Leak Threatens England Site. GREATHAM, England (AP, Feb. 19, 1999) - Environmental teams were struggling Friday to dilute acid that leaked into a protected marshland popular with migrating birds. A drain at Tioxide Europe Ltd.'s Greatham Works plant failed Wednesday, sending hydrochloric acid on to the 750,000-square-foot marsh in northeast England. The marsh has been designated a site of "special scientific interest" for attracting many species of birds. "It is one of the worst incidents I have attended," said Steve Hardy, an environmental protection officer. "It was as acidic as you get." About half the site was affected, he said.
Tokyo Activist Dies of Cancer.TOKYO (AP, Feb. 19, 1999) - Teruo Kawamoto, who fought for victims of mercury poisoning in Japan, has died of liver cancer, a family member said Friday. He was 67. Kawamoto died Thursday at a hospital in his hometown of Minamata, in Kumamoto prefecture, or state, about 660 miles southwest of Tokyo, said his son, Aiichiro Kawamoto. Kawamoto headed a group of victims of "Minamata disease," the sickness that resulted from tons of mercury being dumped into the sea surrounding the town beginning in 1932 and ending in the 1960s. Hundreds died and thousands were disabled by the disease, which caused nervous system damage in the victims and birth defects in their children.
European Protocol On Water and Health(WHO/EURO Press Release, 12 February 1999) From 14-16 February 1999, high-level officials from the health and environment ministries of the 51 European countries met in Bled, Slovenia to prepare an action plan that will form the Declaration at the Third Ministerial Conference on environment and Health in London, 16-18 June 1999. The agenda for the London Conference will include a legally binding Protocol on Water and Health http://www.who.dk/London99/water.htm
An estimated 110 million people in Europe do not have access to safe water. This Protocol, a joint initiative between the World Health Organization (WHO) and the UN Economic Commission for Europe (ECE) sets targets and timetables in three areas: adequate drinking-water and sanitation; safe water for agriculture, aquaculture and recreation; and effective systems for monitoring and managing risks to human health.

Water Scarcity Threatens Food Production. (BBC, Feb. 1999). In a few years, water scarcity will have been translated into food scarcity, according to Dr. Lester Brown, at the presentation the Worldwatch Institute's 1999 State of the World report (http://oneworld.org/ips2/feb01/14_03_042.html). Between 1991 and 1996, the water table under the north China plain dropped by an average of 1.5 m a year. The area produces nearly 40% of China's grain harvest. Water tables in India are falling at 1-3 m each year as groundwater is being withdrawn at least twice as fast as it is being replenished. When the reserves run out, India's grain harvest could fall by as much as a quarter. Contact Worldwatch Institute, mailto:email@example.com
UN Sees Severe Water Shortage. GENEVA (AP, Feb. 4, 1999) - A severe water shortage could have "catastrophic consequences" in some developing countries unless global solutions are found soon, the U.N. weather agency said Friday. Almost 1 billion people could be living in countries with moderate to severe water shortages caused by climate change, contamination and population growth by the year 2025, according to the World Meteorological Organization. That could double again by 2050. Although developing countries make up most of those with severe water shortages, potential problem areas in the future include the west coast of the U.S. More than 150 experts from around the world will hold a U.N.-sponsored meeting in Geneva next week to discuss safeguarding water supplies.

1. Water rationing as a way of life. This boxed item challenges you to come up with community actions to prevent the extensive rationing suggested. Contact the local agency responsible for water management in your community and find out what if any plans they have for water restriction in event of natural disasters, such as flood, hurricanes, and drought.
2. Reducing risks from infectious and toxic agents in drinking water. Compare and contrast the Year 2000 objectives for drinking water in the U.S. with goals of WHO's Decade program for drinking water in developing countries. Identify two infectious and toxic agents you might encounter in water in the United States and water in a developing country.
3. Bottled water. Bottled drinking water appears everywhere these days, from offices, to homes, to over-the-shoulder harnesses for the mobile. Why are so many drinking bottled water? What are the health gains or losses for the decisions they make? Examine the economic, health, and cultural influences of this trend.
4. Recycling. Explore the history of the recycling program in your community. How long has it been in existence? How have strategies changed over time? What are the future needs of the program? Pull out a map to identify where community landfills are located. What is their capacity and how close are they to reaching capacity?
5. Long and winding road. Trace what happens to waste products (use an emptied washing machine, if you wish) as they leave the site of production and move through the city’s water treatment system. Or start with water coming out of the faucet in your home and trace it back to its source. Either direction, the project involves contacting the local water management agency in your community. Further explorations might include considerations of products that contaminate the supply or points at which the supply is vulnerable.
6. Community action. Nicholas Freudenberg's book entitled Not in Our Backyards! Community Action for Health and the Environment, Monthly Review Press, New York, 1984; and the Student Environmental Action Coalition's Action Guide, Earth Works Press, 1991, offer examples of community projects such activities as developing a directory of recycling locations, registering voters, buying recyclable projects, and taking public transportation. Identify some future careers associated with shrinking water supplies, e.g., xeriscape architect.
