How can we prevent water pollution to our environment ?

When we throw something in the garbage, or flush the toilet, we tend to forget about it. Because individuals are responsible for many non-point sources of pollution, we do not always realize how much we are contributing to water pollution. It seems easier to point the finger at agricultural, industrial, and mining operations. However, here are a few tips:
*Conserve water; the less water you use, the less will be running down the drains and into gutters, carrying pollutants with it.
*Keep pet litter and debris out of street gutters.
*Use pesticides sparingly; in general, people tend to use 10 to 50 times more fertilizer on their lawns and gardens than is necessary for good plant health.
*Or, use compost to fertilize your garden.
*Keep your vehicles running properly. If you have an oil leak, fix it immediately, and if you change your own oil, dispose of the used oil properly.
*Use natural cleaners, such as baking soda, vinegar and borax.
*Use detergents with less phosphate; sewage plants can only remove about 30 percent of the phosphates from waste. It is estimated that, in the United States, between 90.7 million and 226.8 million kilograms of phosphates are added into waterways each year.
