What are the negatives of water pollution?
Hey everybody
Im doing a school project and its on water pollution. I need to know the negatives.
I hope you guys can help me!!
Thanks!
If asked to name types of water pollution, the average person would probably mention things like bacteria, pesticides, trash and oil. More knowledgeable lake users would also include nutrients and sediment on the list. The aforementioned categories have made up much of what we know of as water pollution, but there are new types of contaminants that are making headlines; pharmaceuticals and personal-care products! These contaminants, along with cleaning products, make up what is known as Organic Wastewater Contaminants (OWC’s).
Pharmaceuticals include antibiotics, estrogen (natural and synthetic), steroids, and prescription drugs. The personal-care products are items such as sun-block, perfumes and insect repellents. In a way these items are not really “new” pollutants, as they have probably existed in the environment ever since we started to use them. What has changed is our ability to measure them in small concentrations (also, an increased population means more of these materials are making their way into our environment).
How prevalent are they? A recent study by the U.S. Geological Survey found trace amounts of at least one OWC in 80% of the 139 streams monitored. The streams were located throughout the country and the findings suggest that these pollutants are widespread. This may lead to the question - How do they get into the environment? Often the answer is through sewage treatment plant effluent. Any medication that is not totally used by the body is past out as waste, while personal-care products are constantly being washed down the drain when we bathe. Treatment plants are not set up to remove pharmaceuticals and personal-care products from the effluent. These contaminants may also move through septic systems or come from improperly disposed of chemicals (cleaners dumped down storm drains). Humans may not be the only source of OWC’s. Antibiotic and hormones used on livestock may also contribute to the problem.
Try google.

icky water of course and it may smell bad plus you wouldn’t be able to drink it

Put it this way there are no positives

Well for one it obviously contaminates the water. Plus it kills the animals that are living in the water such as fish and others. It polutes the air because water does evaporate. I could go on and on but I know its just not a good deal.

We can’t drink polluted water. Now what was that thing sea critters need? (clean water)

"Water pollution is the result of human activities as almost any human activity can have effect on water quality. Contamination of lakes, rivers, and oceans happens every day threatening animals and plants that live in these water bodies. Water pollution is burning problem that needs to be solved but this is very difficult because there are so many different causes of water pollution, and we should solve every single cause in order to completely solve this problem. However we can point out two main causes for water pollution: sewage waste and waste water.
When thinking about water pollution many people think primarily of sewage waste. This is understandable given constant increase of human population, and the fact that many people in undeveloped countries still lack even the basic sanitation (toilets). Sewage disposal problem is more serious problem than many people think, and it often results in water-related illnesses such as diarrhea, that by some estimations kills more than 4 million children each year. But the problem with sewage doesn’t lie only in countries of the third world, but also in many developed countries."
