Water flow system used several times before reaching the ocean. People drink it, cook with it, bathe, and swim in it. Farmers in food production, the use of water, the use of e-commerce and enterprise. Water to support fish, wildlife and recreation, and to create an aesthetically pleasing environment.
With all of its uses, the need for good water quality is imperative. Good quality water contains high enough physical, chemical, and biological characteristics, in order to maintain it all uses.
Water quality is a reflection of the body's natural processes and human activities affect the composition of the water. The water quality has many different definitions. Ecological scientists, it means that the balance and normal functioning of aquatic ecosystems; A public health officials, which means clean, clear drinking water and local fishermen, which means that the quantity and quality of the fish.
The pollution is an adverse change in the physical, chemical, or biological characteristics of air, land, water, living conditions adversely affect humans or other organisms. Water Pollution is detrimental, unreasonable impairment of water uses beneficial to humans.
Water quality by direct and indirect sources. Direct source is quite obvious, including this practice of dumping of waste and harmful pollutants into streams. Indirect sources, known as non-point source (NPS) pollution. Stormwater runoff, which may include fertilizers and pesticides, soil loss of land for development, residual oil washed off the street, non-point source pollution. This type of contamination is more difficult to accurately locate and control.
Difference
Practice water conservation. Use less!
Stop-point source pollution in the backyard, lawn care through the use of appropriate technology.
Restrictions on the use of pesticides and fertilizers. The recommended amount of this year, the appropriate time to use them.
Prevent property debaucjed. Cover and vegetation cover bare soil.
Encourage local governments to make a high priority for water quality improvement.
Encourage the development of environment-friendly society.
Participate in stream clean-up program.
Learn to recognize the quality of water in local streams.
Will bring water quality problems to the attention of the appropriate government officials.
Water pollution of the waters of one or more natural or artificial substance too?? Much. Natural sources of pollutants, including sulfur soil, iron ore deposits, volcanic springs, calcium and tannic acid and wetlands methane gas residue. The two main types of anthropogenic pollutants point source pollution and non-point source pollution (NPS).
Point source pollution
Point source pollution comes from a single source, such as pipes, culverts, ditches. Usually associated with point source pollution of industrial land, the sewage outflow pipe or sewage treatment plants. The signs of pollution, most people can identify pipeline, algae growth stream discharged from the outfall, the smoke from the chimneys of the multicolored liquid from the garbage dump.
Non-point source pollution
Non-point source pollution presents a more subtle water quality problems, because it originated in a widely dispersed and diverse sources, rather than a single outlet. Natural forces such as rain or wind can often play a key role in the transport the pollution logistics system. Examples of non-point source pollution is the development of the field of soil erosion land; chlorinated pool water into the sewer or directly to the flow of runoff from the backyard containing fertilizers and pesticides; pet waste, oil, paint thinner, or antifreeze dumped in the sewer; Oil other substances washed off streets and parking lots.
Pollution control
Point source pollution control, during the past 50 years, through sewage treatment, air scrubbers, filtration equipment. Municipal and industrial sources of pollution clean-up, resulting in significantly improved water quality in streams.
One example is, until recently considered polluted rivers Potomac River. Point source pollution control recovery of the Potomac River, and many other major river systems has contributed, in all parts of the country.
There is still a long way to go. The major sources of pollution continue to enter the flow and non-point source pollution, the main culprit, accounting for more than 50% of the nutrients in Chesapeake Bay.
Difference
At home, in the yard.
Fertilization based on soil test results.
Application of pesticides, according to the instructions on the label.
Maintenance of septic tank systems.
Recycling of grass clippings and leaves from coverage or compost.
Recycling of used oil.
Collection of garbage and animal feces.
Large tracts of grass to dissipate chlorine, and allow the water to filter through the soil drainage pool.
Water conservation.
Seeding grass to control soil erosion, install sod, or planting ground cover to protect the exposed areas.
Direct water on the roof grass.
The use of a porous surface, such as slate or gravel instead of asphalt or concrete.
The correct handling of household hazardous waste. Never pour paint, antifreeze, motor oil, cleaning agents or solvents down the drains within the family or external.
Non-point source pollution is how it happened.
Rain, regardless of the amount, to washing from the land into the serious pollution of lakes, bays, rivers, streams and underground aquifers. Where rainwater can not seep into the soil, it runs, erosion of bare land, and filling the street gutter.
Enter the the urban rainwater pipe line, sometimes directly into the surface water, rainwater or snowmelt runoff torrent swept through the accumulation of dust, dirt, debris, organic matter, toxic pollutants roads, construction sites, and lawn. The farm runoff channel water into a stream, and a large body of water turbidity, sediment, fertilizer and pesticide residues, salt and animal feces. The adverse effects of non-point source pollution involving how close the source of water, land use, soil type and slope of the land, although several storms from distant sources may reach the same body of water pollutants.
Non-point source pollution is not limited to one region. Ninety-nine percent of sediment, 88% of nitrate and 84% of the phosphate into the lakes and streams of the United States is considered a non-point source pollution.
The impact of non-point source pollution.
Poison fish, aquatic animals and wildlife.
Cover fish spawning beds, kill fish eggs.
As grinding mechanism riverbed, the destruction of living in the bottom of macroinvertebrates, fish and reptiles logistics aquatic organisms.
To increase the decomposition of the organic debris, the consumption of oxygen in the water, is necessary to support the life of aquatic animals.
Fill in the streams and reservoirs.
Add nitrates and phosphorus in the water caused the death of a lot of algae and the potential of lakes and estuaries. |
