81. Water Pollution water pollution. The question immediately arises if the pollutants are nontoxic, how can they have such serious consequences for waters receiving them? http://www.enfo.ie/leaflets/bs11.htm

Water Pollution THE simplest definition of water pollution is "the loss of any of the actual or potential beneficial uses of water caused by any change in its composition due to human activity". The beneficial uses of water are varied and include its use for drinking and for domestic purposes, for watering livestock and the irrigation of crops, for fisheries - both game [salmonid] and coarse [cyprinid], for industry and for food production, for bathing and for recreational and amenity use. If water is rendered unsuitable for any of these purposes then it is polluted to a greater or lesser degree depending on the extent of the damage caused. The inclusion of the word ‘human’ in the definition is necessary because water may be naturally impaired in quality either temporarily or permanently. NATURAL WATER Pure water- H2O - water absolutely free from any substances dissolved in it - does not exist outside the laboratory, as natural water contains dissolved gases and salts. - These substances which are often the very factors which make the water suitable for particular beneficial uses. Water must have an adequate level of dissolved oxygen if fish are to thrive - without it they will die. (As explained later, the great majority of pollution instances on our rivers are attributable to the depletion of the dissolved oxygen, leading to various highly undesirable effects.) Again, drinking water without dissolved oxygen and with only a very low level of dissolved salts, is not very palatable: it is the level of salts in solution - as natural ‘hardness’, for example - which gives many waters their palatability.

Data and statistics Water pollution Water pollution Eutrophication Hazardous chemicals in coastal waters Oceans ... Data and statistics Pollution and hydropower developments are threats to Norway's rivers Compared with most other countries, Norway has abundant supplies of clean fresh water. Nevertheless, pollution from settlements and agriculture affect water quality in Norwegian lakes and rivers. Pollution of watercourses may result in poorer drinking water quality, cause fish mortality, and reduce the value of rivers and lakes for bathing and other outdoor recreation. Eutrophication of fresh water, caused by excessive inputs of nutrients, disturb ecosystems and may cause algal blooms. Long-range pollution from other countries has caused acidification of lakes and rivers, particularly in Southern Norway. After the Second World War, the rising demand for energy has led to extensive hydropower developments with a growing impact on river systems. Seas and coastal waters are vulnerable to pollution Norway's seas and coastal waters are generally clean and healthy. However, coastal waters in Southern Norway are affected by discharges from municipal waste water, agriculture and industry, and long-range pollution from the North Sea. Other long-range pollutants are also carried to Norway by winds and ocean currents.

84. Storm Water Pollution Prevention Plans Storm water pollution Prevention Plans. This guide is 800952-2490. Storm water pollution Prevention Plans Step-By-Step Summary. http://www.history.rochester.edu/class/storm/storm.html

Storm Water Pollution Prevention Plans This guide is intended as a brief summary of the steps needed to start a storm water pollution prevention plan, not as a manual. Permittees should contact the EPA or your state environmental agency for detailed directions. - Overview - Storm water runoff is simply rain water or snow melt that runs off the land and into streams, rivers, and lakes. When storm water runs through sites of industrial activity it may pick up pollutants and transport them into national waterways and effect commercial fisheries, restrict swimming areas, and affect the navigability of the nation's waters. To help curb the problem of storm water runoff pollution the EPA (Environmental Protection Agency) has developed a program under the Clean Water Act. A major part of this program is the NPDES (National Pollution Discharge Elimination System) which requires industrial activities to register for a discharge permit. Many industrial activities can apply under a general permit. To find out if you can register under a general permit, contact your area office. In many states, including New York, this is accomplished by the state governmental environmental department. In New York the DEC (Department of Environmental Conservation) issues discharge permits under the SPDES (State Pollutant Discharge Elimination System) program. In New York, industrial activities must submit an NOI (Notice of Intent) to determine whether they are eligible for a general permit. If you have questions on permit regulations, or whether you are eligible under a general permit you can call the EPA's storm water hotline at 703-821-4823. In New York you can call for copies of the General Permit or NOI forms at 1-800-952-2490.

Gillam, Susitna Elementary, Anchorage, AK Date: May 1994 Grade Level(s): Kindergarten, 1, 2, 3, 4, 5, 6 Subject(s): Science/Environmental Education OVERVIEW: There are a wide variety of pollutants that can affect water and the plants and animals that live in the water. This pollution can be divided into three groups: chemical pollution, thermal pollution, and ecological pollution. Since not all pollution is human produced students need to understand that there are sometimes "natural" reasons for some pollution. PURPOSE: These activities will help students' understanding of water pollution and its potential effects on human and wildlife habitats. OBJECTIVES: Students will be able to: Identify 2 or more pollutants in a bog, marsh, stream or other wetland area. Relate a pollution prevention message through words and art. Understand that some pollutants can not be seen.

Sources of Water Pollution What are the sources of water pollution? What are the effects of water pollution? What are the ways we can take to decrease those problem? a)What are the sources of water pollution? There are many causes for water pollution but two general categories exist: direct and indirect contaminant sources. Direct sources include effluent outfalls from factories, refineries, waste treatment plants etc.. that emit fluids of varying quality directly into urban water supplies. In the United States and other countries, these practices are regulated, although this doesn't mean that pollutants can't be found in these waters. Indirect sources include contaminants that enter the water supply from soils/groundwater systems and from the atmosphere via rain water. Soils and groundwaters contain the residue of human agricultural practices (fertilizers, pesticides, etc..) and improperly disposed of industrial wastes. Atmospheric contaminants are also derived from human practices (such as gaseous emissions from automobiles, factories and even bakeries). Source: Our Planet , Vol 8, No.3, 1996.

G.Info: State of the Environment - Georgia - Water Water Pollution Problems The most polluted rivers in Georgia are the Mtkvari, Rioni, Kvirila, Galidzga, Tkibuli, Enguri and Gubistskali. In most of these rivers, concentrations of phenols, hydrocarbons, copper, manganese, zinc and nitrogen are considerably higher than the national and international standards. Most water treatment plants are not operating or work at a very low level of efficiency. It is stated that more than 60% of the sewage treatment plants is obsolete and in urgent need of replacement. Coliform levels in reservoirs and water supply systems have reached dangerous levels in many areas. According to the information collected in 1994, some 55.7% of the population lives in urban areas. That is the main reason why many of the country’s pollution problems are concentrated in several municipal areas, which are also industrial centres: Tbilisi (population of 1.242 million), Kutaisi (population of 240,200), Rustavi (population of 155,200) and Zestaponi (population of 51,300). The cities suffer from aging municipal infrastructure (MIRP) , insufficient or in many cases no waste water treatment facilities, and inadequate waste management facilities and practices. Surface waters on which municipal areas depend are polluted with municipal sewage and industrial discharges, although the latter source has declined under current economic conditions.

95. Water - Pollution And Health An outline of issues relating to water pollution and contamination with refernce to human health. Water pollution and health. Chemical http://www.agius.com/hew/resource/water.htm

Water - pollution and health Chemical: Water can be an important source of chemical hazards. It can leach lead from pipes especially if the water is soft and has a low pH. There is good epidemiological evidence that this can have a relatively small but measurable harmful effect especially on neurological function even at levels hitherto considered "acceptable". Other adverse effects can arise from chemicals added to the water. Chlorination of water has probably saved millions of lives (see biological hazards). Some concern has been raised about possible increased cancer risks in association with chlorinated water but there is as yet no proof that a causal association between the two exists. Fluoride added to water reduces the risks of caries but can also have unwanted effects such as mottling of the teeth. The accidental tipping of a large quantity of aluminium sulphate in the Camelford incident a few years ago resulted in acute health effects although there is controversy about chronic effects. Nitrate in water usually arising from fertiliser leaching (natural or artificial) can increase the risk of methaemoglobinaemia ('blue babies') in bottle fed infants but this is extremely rare. Although pesticides can and do leach into water, there is no evidence that the current standards for water quality are inadequate in this respect, but most standards are based on evidence other than human epidemiology which in this context is extremely difficult to conduct. Beyond the point of supply further problems in drinking water quality may result. Thus for example water tanks containing lead may increase the burden of this metal in the water, while water softeners may increase its sodium content (This can be harmful for bottle fed infants).
