With many countries, both modernized and third world alike, being greatly affected by this problem it is sure to remain a prevalent topic in political and environmental debates for quite some time. Questions about the causes, results, statistics and solutions to water pollution and the problems it causes should be placed here.

Is siltation a pollution in water?
Siltation is a form of water pollution it is caused by the particles of soil, silt and clay entering the river, or lake or practically any body of water, it is caused by soil erosion and the process can typically be accelerated by farmers or construction sites of nearby areas of bodies of water, in other words by human activity. This can cause an entire ecological system to fall apart and cause species of aquatic fish such as the endemic species of the cichlids (a species of fish) or even coral reefs of the sea for example. So in short yes siltation is a form of water pollution and it may also be named sediment pollution.

What pollution causes due to textile industry?
The textile industry is plagued by air pollution problems which must be resolved. In particular, smoke and odor arising in the process require abatement.The major air pollution problem in the textile industry occurs during the finishing stages, where various processes are employed for coating the fabrics. Coating materials include lubricating oils, plasticizers, paints and water repellent chemicals -- essentially, organic (usually hydrocarbon) compounds such as oils, waxes or solvents. The main air pollution problem in the textile industry is the creation VOCs, which take the form of visible smoke and invisible but objectionable odor. The odors associated with textile plant emissions are usually caused by hydrocarbons with molecular weight less than 200, and fewer than 15 carbon molecules (C1 to C14).
Why is ballast water is a problem to water systems around the world?
Ballast water is water taken on board a ship in special tanks to compensate for a light load and make the ship ride properly in the water. It is then pumped out before the ship is loaded with cargo. Because it is unfiltered, when it is put in the tanks it may carry all manner of plants, animals, seeds and whatever. These are then released to the environment wherever the tanks are pumped. A number of harmful creatures and plants have entered new environments in that fashion. Since they have no natural enemies there, they often overpopulate and cause difficulties ranging from blocking water intakes on power plants to destroying local fish populations.
Why is stagnant water harmful?
Stagnat water is not running water. Due to this it may be home for mosquitoes. so the stagnant water is harmful to our health

How do you rehabilitate a stream contaminated by sewage?

Can fertilisers cause water pollution?
Yes they cause water pollution, as they are chemicals which are use to improved the quality and quantity of crops, but at last they settle at bottom of the crop, and get mixed with soil. And with rain they gets dissolved with soil , later when the rain water gets down under soil , they also get mixed in the water and cause water pollution.
Why might a scientist studying water pollution work with percents less then one?
The majority of pollutants reach levels that cause environmental impacts at part per million levels, this is 0.00001%. These levels, if expressed as percents, would require extensive careful reading to get correct and present oportunites for typogtaphical errors. AT lower levels such as part per billions this problem becomes even more evident.
Thypical pollutant level limits for metals are generally 1 ppm, for phenols 15 ppb.
Is car exhaust a point or non-point source?
Exhaust from a car is a non-point source pollution, because you are unable to mathematically pin point the source of pollution.
Answer:
The exhaust from a specific car is a point source, the tailpipe. Car exhaust in general for a city is non-point source as it arises from many locations simultaneously.
What are the five water quality indicators?
Fertilizers, pH levels, dissolved oxygen, turbidity, and fecal coliform (for those of you who do not know what that is, it's bacteria found in poo.)
What are the ways to minimise the water pollution?
dont trow your garbage in rivers
always wait for the collector to come before you trow your garbage
