WATER POLLUTION - Urban
PREVENTING URBAN water pollution. Thus, storm drains carry large amount ofpollution away from urbanized areas mixed with the excess storm water.
http://www.cjnetworks.com/~sccdistrict/resubwt.htm

Extractions: TO MAIN MENU 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.

Water Quality: Causes And Sources Of Surface Water Pollution
The sources of water pollution typically fall into one of two categoriespointsource pollution and non-point-source pollution.
http://www.texasep.org/html/wql/wql_2sfc.html

Extractions: Nutrients - 0.6% Source: EPA, National Water Quality Inventory, 1998 The major causes of pollution in surface water in Texas are high fecal coliform levels, low dissolved oxygen, metals or other toxics such as organics in water and fish and elevated concentrations of dissolved solids. Overall, in Texas, 59 water body segments have been impacted by high fecal coliform levels in water or shellfish, while low dissolved oxygen has impacted 33 segments. Other causes of impairment include high metal content (33 segments), high organics in fish and shellfish (36), and elevated concentrations of dissolved solids (17). However, each type of water body is impacted by different types of impairment. Major contributors to nonsupport of uses in bays included elevated fecal coliform bacteria and low dissolved oxygen contents. In the streams and rivers, the most frequently violated water quality standards were those for pathogens (high levels of fecal coliform bacteria), low dissolved oxygen, and, in some areas, toxics such as metals and pesticides. Excess plant nutrients (nitrogen and phosphorus) also were identified as a problem in some waters of the state. In reservoirs, impairment of use was related to elevated levels of metals and high levels of pathogens and pesticides.

Extractions: anly Council has joined forces with the NSW Government Stormwater Trust and the University of Western Sydney (UWS) to develop a unique program linking environmental education, water quality monitoring, infrastructure provision and legislation to address concerns about ecosystem health in the catchment of Balgowlah Industrial Estate. The project is funded by the EPA as part of their $80 million effort to combat urban stormwater pollution in New South Wales. The Great Estate Stormwater Environmental Education Program (SEEP) is an environmental education program for companies in the Balgowlah Industrial Estate. It is an opportunity for responsible local business operators to become involved in a program that aims to ensure that our creeks, lagoons and beaches are kept pollution free for the native animals and plants that live there and also for recreational purposes and our future generations. Over 100 businesses in this area have been recognised as having a medium to high risk in terms of actual or potential stormwater pollution problems. The program is designed to address the issue of polluted stormwater runoff from these premises.
Smart Communities Network: Water Efficiency Pollution Prevention
The sources of water pollution are classified as point sources and nonpointsources. Point sources discharge pollutants into surface waters or into
http://www.sustainable.doe.gov/efficiency/wpinfo.shtml

Extractions: Critical to preserving our increasingly scarce sources of freshwater is minimizing the pollution of rivers and streams, lakes and reservoirs, estuaries, wetlands, and groundwater. According to the EPA, these precious water resources are continuously contaminated by the following array of pollutants: The sources of water pollution are classified as "point sources" and "nonpoint sources." Point sources discharge pollutants into surface waters or into groundwater through a detectable "point, " such as pipes from industrial facilities, treatment plants, and combined sewers. Most point discharges are strictly controlled through specific permits and are subject to enforcement actions. Although point sources still contribute some to water pollution, control measures have greatly reduced their impact. Nonpoint sources (NPS), however, are much more difficult to identify, and deliver the vast majority of pollutants to bodies of water. Nonpoint sources include atmospheric deposition, contaminated sediments, and land practices that generate polluted runoff such as agriculture, logging, onsite sewage disposal, and municipal stormwater management.

http://www.ci.san-jose.ca.us/esd/wpcp.htm

Extractions: Water Pollution Control Plant About the Plant The San Jose/Santa Clara Water Pollution Control Plant is one of the largest advanced wastewater treatment facilities in California. It treats and cleans the wastewater of over 1,500,000 people that live and work in the 300-square mile area encompassing San Jose, Santa Clara, Milpitas, Campbell, Cupertino, Los Gatos, Saratoga, and Monte Sereno. The Water Pollution Control Plant has the capacity to treat 167,000,000 gallons of wastewater per day. It is located in Alviso, at the southernmost tip of the San Francisco Bay. Originally constructed in 1956, the Plant had the capacity to treat 36,000,000 gallons of water per day and only provided primary treatment. In 1964, the Plant added a secondary treatment process to its system. In 1979, the Plant upgraded its wastewater treatment process to an advanced, tertiary system. Wastewater from sinks, toilets, and drains inside homes, businesses and schools in most of Santa Clara Valley travels through an underground pipe system, known as the sanitary sewer system, before it arrives for treatment at the San Jose/Santa Clara Water Pollution Control Plant. That journey can take up to 10 hours. About 18 hours later, 99% of the impurities have been removed through a highly sophisticated treatment process that simulates the way nature purifies water, but at a greatly accelerated rate.

Combined Air And Water Pollution Control System
COMBINED AIR AND water pollution CONTROL SYSTEM. NASA seeks to transferthe NASAdeveloped air and water pollution control system.
http://techtran.msfc.nasa.gov/Patents/(21).html

Extractions: NASA seeks to transfer the NASA-developed air and water pollution control system. This system, developed at NASA's Marshall Space Flight Center (MSFC), is a recirculating, bioaquatic pollution control system which combines both water and air pollution controls into one system. Air pollution from automobiles, industrial plants, coal burning power plants, incinerators, and furnaces have created serious environmental pollution problems. These problems include depletion of the ozone layer, the greenhouse effect, as well as air pollution with heavy metals, toxic organics, and acid rain. Current air pollution control systems are expensive to install and operate, or their air pollution control efficiency is questionable. The pollution control system can be implemented to process polluted air created by industrial furnaces used in power generation, incinerators, and industrial applications. The benefits of the combined air and water pollution control system is the low cost of implementation and reduced disposal costs compared to existing pollution control alternatives. This system eliminates the need for baffles, venturis, and injectors used in conventional systems.

TEACH: Water Pollution In The Great Lakes
water pollution in the Great Lakes water pollution is defined as a change in the chemical,physical and biological health of a waterway due to human activity.
http://www.great-lakes.net/teach/pollution/water/water1.html

Extractions: 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.
