What is water pollution?

Question

What is water pollution?

Answer 1

its when toxins or somethinf like that get into the water, polluting it

Answer 2

when harmful things get in water

Answer 3

what brittany said

Answer 4

When The Water Gets Polluted,Its When Something Gets Into The Water Like Orange Juice (Very Low Chance Of Happening).

Answer 5

Water pollution is the contamination of water bodies such as lakes, rivers, oceans, and groundwater caused by human activities, which can be harmful to organisms and plants which live in these water bodies.

Answer 6

it's when water is polluted.

Answer 7

Water pollution is any added material to water than impacts it's ability to carry oxygen, or to provide sustenance to life.

Depending on the situation, *anything* can be classified as water pollution. Most cities and towns in the "modern" world flouridate their water to help prevent some dental issues. If said municipal water entered the water table, it would be classified as pollution, because the flouride will actually kill needed organisms in the food chain.

A cardboard box floating down a river is water pollution.

Salt poured into a body of fresh water is pollution, despite the fact that 80%+ of all water on the planet is salty.

etc...

Good Luck!

Water pollution is the contamination of water bodies such as lakes, rivers, oceans, and groundwater caused by human activities, which can be harmful to organisms and plants which live in these water bodies.

Although natural phenomena such as volcanoes, algae blooms, storms, and earthquakes also cause major changes in water quality and the ecological status of water, water is typically referred to as polluted when it impaired by anthropogenic contaminants and either does not support a human use (like serving as drinking water) or undergoes a marked shift in its ability to support its constituent biotic communities. Water pollution has many causes and characteristics. The primary sources of water pollution are generally grouped into two categories based on their point of origin. Point-source pollution refers to contaminants that enter a waterway through a discrete "point source". Examples of this category include discharges from a wastewater treatment plant, outfalls from a factory, leaking underground tanks, etc. The second primary category, non-point source pollution, refers to contamination that, as its name suggests, does not originate from a single discrete source. Non-point source pollution is often a cumulative affect of small amounts of contaminants gathered from a large area. Nutrient runoff in stormwater from sheet flow over an agricultural field, or metals and hydrocarbons from an area with high impervious surfaces and vehicular traffic are examples of non-point source pollution. The primary focus of legislation and efforts to curb water pollution for the past several decades was first aimed at point sources. As point sources have been effectively regulated, greater attention has come to be placed on non-point source contributions, especially in rapidly urbanizing/suburbanizing or developing areas.

The specific contaminants leading to pollution in water include a wide spectrum of chemicals, pathogens, and physical or sensory changes. While many of the chemicals and substances that are regulated may be naturally occurring (iron, manganese, etc) the concentration is often the key in determining what is a natural component of water, and what is a contaminant. Many of the chemical substances are toxic. Pathogens can produce waterborne diseases in either human or animal hosts. Alteration of water's physical chemistry include acidity, electrical conductivity, temperature, and eutrophication. Eutrophication is the fertilisation of surface water by nutrients that were previously scarce. Water pollution is a major problem in the global context. It has been suggested that it is the leading worldwide cause of deaths and diseases,[1][2] and that it accounts for the deaths of more than 14,000 people daily.[2]

Answer 9

usually it comes from smog that rains into the water supply or else stuff that gets dumped in the lake or when the sewage pipes overflow. Most water is at least a little polluted. It's best to always filter and boil your tap water because whenever the water supply gets contaminated you hear about it after the fact on the news (if you eve watch the news). I got really bad e coli poisoning from tap water in New Jersey so I'm not joking.
