Pollution of Drinking Water Supplies

It is well known that water covers almost three quarters of the earth's surface. However, it is well known that more than 99% of the earth's water can not be used by humans and many other organisms. Less than 1 percent of water supports most of the lifestyles we are familiar with. Unfortunately, 1% of freshwater contamination is serious every year. Little is known about the annual charge of pollutants in our canal. Water pollution arises from a variety of unique causes including industrial waste, urban rainwater, agricultural outflow water, various household chemicals, and even nuclear waste.

Contamination of drinking water supply may suddenly occur due to changes in water supply, or pollutants may be a legacy of past policy decisions. Presently in California, estimated 123 trichloropropane used for agricultural production until the 1970s have been controlling parasitic root nematodes for nearly 40 years. Although it was canceled, 1,100 3-TCP has been detected from about 100 public water systems in Central Valley to Santa Cruz and Los Angeles. Approximately 30 communities are appealing by Dow Chemical and Shell for pesticide use and subsequent soaking in groundwater

One of the reasons that this is not currently true is that people in many countries ensure that the supply of drinking water is drinking. Always check bacteria and chemical substances in water that may contaminate water. If drinking water is not safe, please dispose of it. All measures taken to ensure that drinking water can be drunk are called water treatment. The excavated dam is made by digging the soil to make a large shallow hole. These dams are sometimes placed on the bottom of the slope to help collect water. However, this can only be done in areas where the soil does not allow water to easily escape through the ground. For example with clay

Water: Chemical substances discarded in the water supply system or chemicals flowing into the water from the surrounding environment can cause water pollution. Because our planet has very little water, only about 3% of the earth's water can be drunk, 2% of which are sealed in glaciers - this will lead to a crisis soon. From the perspective of human concern, it seems to be somewhat self-centered, but pollution directly affects human health. Contamination by air, soil and water causes pollution about 40% of deaths on a global scale. Air pollution causes respiratory diseases such as lung cancer. Even those who have never smoked in a day. Contaminated water can get sick - more than 1.2 billion people do not even have clean drinking water or are used for cleaning. Contaminated soil can spread toxins and chemicals directly to our food
