It gets polluted by acid rain, oil spills, litter, insecticide mixing with fertilizers etc.
1. The emission of waste heat from an electric generating station into a lake, causing common change through their stress.
2. the discharge of nutrients containing sewer wastes, in a water body causing eutrophication.
Uncontrolled algae growth
Phosphorus pollution
Sources of pollution are storm water runoffs, combined sewer overflows, sanitary sewer overflows, failed septic tanks, leaking oil storage tanks, and more.
1. Illegal dumping of industrial waste
2. Rainwater or snowmelt that runs over the land, picking up pesticides, and fertilizers; called runoff
3. Used water from people's homes and communities; called wastewater
All of the above.
There are several things that can pollute water, from the sewage of your drains to the major oil spills around the world. Some examples may be wastewater, which is water that contains waste products from washing dishes, clothes, or a factory that uses water to clean its facilities or make products.
Rain washes off the oil that cars drop on the roads. This runs into gutters and then into waterways.
Water pollution may be both natural or man-made. Obviously man-made water pollution is more significant.
Natural Water pollution;
As water flows down a slope (such as a river) it drags with it all kinds of impurities. These impurities can be heavy metals (such as Arsenic, Lead, Cadmium and Mercury) or soluble impurities (such as Magnesium sulfate or calcium sulfate). These substances are naturally found in the soil.
Water can also be polluted because of substance being released from a nearby volcano. An example is the Anchorage volcano of Alaska which releases huge amounts of Sulfur in the water bodies. As a result the water becomes extremely acidic (due to the formation of sulfuric acid) - this is detrimental to aquatic life.
Pollution due to man-made activities;
One form is to aggravate the natural discharge of heavy metals and other impurities. By working with the soil close to water bodies, the harmful discharge is accelerated. Example of "working close to water-bodies" leading to pollution is the extraction of Gold)
Acid rain are caused due to man-made activities. They cause the acidification of water.
Discharge of water mixed with various detergents from industries and homes.
Discharge of dirty water from industries add impurities and heavy metals (especially from dye-industries).
Untreated sewage water (from septic tanks) leeks into water bodies.
Excess fertilizers leech into water bodies. This promotes the excessive growth of algae (known as algae-bloom). The algae uses excessive oxygen causing other aquatic organisms to suffocate and die. Aerobic bacteria act on the dead organism and further depletes the oxygen content of the water body. Finally the algae also suffocates leading to a lifeless and polluted water body.
This is what I learnt,

The water is poluted by humans throwing matirials in the water(like...bottles,cans,paper,cann holders ect.) People don't notice its killing our earth. It's also hasourdes to all the fish. These things make water VERY unsafe for our fish to swim in.
HELP THE EARTH!!!!!!
Well there are many ways it can be polluted. Such as that, it occurs sometimes because of our human activities. Causes that are so little to notice, makes a big difference in the marine ecosystems. How water is polluted because of oilspills, may be some species that also pollute the water with their wastes. When you litter on the street, it gets caught in the drains and out to the sea. Disgusting things can effect our sea and oceans. So next time, if you see someone litter tell them to pick it up. Your helping the enviroment.
the most common way is cans and plastic water bottles and chip and candy wrappings and every day life kids who don't have a water shed like seattle have they cant or don't have access to clean water 50% of the earths surface of water is polluted 1.1 million people lack assess to clean healthy drinking water like 500 to 900 people die pur week because they don't have clean drinking water .
Think about it. If you dump motor oil in the water, you polluted it. If you take a "dump" while sitting on the toilet, you polluted the water. The list of ways goes on and on.
Water ways get polluted when rubbish or unwanted liquids go in there. By Annie and I hope this helps
People throw trash in the water
when u have sex
well,i think waterways are polluted cause we use them too much.
if thers poo floating thru it nd it stinks

Platypuses' habitats can be polluted by chemical and agricultural runoff, or even by industrial runoff in some areas. Anything that pollutes freshwater waterways can pollute the platypuses' habitats.
the environment could be polluted if there are oil spills and gas leaks,especially when people dispose of rubbish on the ground.the rubbish ends up in our waterways,where fish and other marine creatures could be harmed.sewage is another problem.it effects the environment by killing both flora and fauna,and again,polluting the waterways.
Yes as long as you take necessary precautions if to somewhat polluted waterways etc. yjnk;l;injpo\ntrkgmrklltrh;lty;lhtytrth;lyhyu;,y;
Some of the pesticides sprayed on farm crops wash off in the rain and get into the waterways. The water plants absorb the pesticides.
There are several waterways around the UK. A few of the waterways are the West Midlands Waterways, South Wales and Severn Waterways, and the North East Waterways.
Well first of all the water was not polluted (but if so they clean animals in it) they could be poisoned by other religious people (Like Middle age Islam and Europe in the crusades). Actually, it could be polluted. Of course there were no dangerous gases to pollute it, but everyone littered. They just left their trash on the ground since there was no where else to put it. The trash would eventually go into the water and pollute it. This is what caused the black death (or plague.).
polluted fuels are which get polluted by burning of trash and garbage and , this is called polluted fuel
a air polluted place is a place in which air is polluted in India Delhi is the most polluted
Polluted The Polluted creek is full of garbage.
