In 1950, the United States took out of the land 12 trillion liters of water; by 1980, this figure more than doubles and is still increasing at an alarming rate. Aquifer Ogallala depleted at a rate 12 Bln. Cube. M (Ft 420 billion or 9,729,000 acres ft.) Per year, that is up to date on the complete depletion of & # 39; volume equal annual Colorado river stream 18 (4000 cubic feet). per second).
Time magazine reported: "aquifer Ogallala sucked dry Some estimates say that it dries in just 25 years, many farmers in the Texas High Plains, which are particularly rely on groundwater sources, are now turning away from irrigated agriculture As of & # 39; appearance!. hazard peranaselennya aquifer stretches from South Dakota through Nebraska, where two-thirds of the water is up to Wyoming, Colorado, Kansas, Oklahoma, New Mexico and Texas. farmers pumped water from the Ogallala as if she nevych . Annual arpalnaya on & # 39;. The amount of water that is replenished, almost equal to the Colorado River Flows engineering firm Camp, Dreser and McKay, estimated that in 2020 about 5.1 million hectares of irrigated land is dry.
Today the American south-west with a & # 39 is the most heavily irrigated area in the world, transforming the desert into a veritable Garden of Eden. However, this strong irrigation can destroy the earth with salt seepage. Colorado River at 1,400 miles long – it is a life of 11 million people from Denver to San Diego. In fact, today, 1.5 million hectares of irrigated farm beautiful. This beautiful river is slowly being poisoned load of salt from saline wastewater western soils and salt concentration caused by evaporation and increase the use of the river in the seven states that were granted. salt level reaches more than 800 milligrams per liter, and are expected to soon reach 1200 m / l. EPA maximum safe level for drinking water of 500 ppm, 500 ppm is considered to be unfit for drinking. (This means a teaspoon of salt per gallon of water.) In addition to the depletion of underground sources of water, less precipitation falls on the land and over to the ocean, which is associated with displacement of air streams and globally changing conditions outside the & # 39; I.
WHAT CAN BE arrival?
As if the reduction in the water supply was not bad enough, we are rapidly destroying the little water that we have left with hazardous waste. Toxic chemicals on thousands of hazardous waste across the country continue to penetrate underground country, contaminating the land and groundwater and poison the air. The US General Accounting argues that Super Fund program will need to clean up more than 10 000 sites, it seems, is now a & # 39 is an overwhelming task. Six billion tons of solid and hazardous waste generated in the US each year. 400 million pounds of toxins each year is displayed in our waterways American industry given by the Environmental Protection Agency show environment (EPA). Recent research projects that at the current rate will take 30 to 35 years and 253 billion dollars to clean up most of the famous places in the country for toxic wastes that are still to be discovered. EPA expects that it will need to convert at least 294,000 sites for hazardous waste – and this amount may be up to 355,000.
E.P.A. in the implementation of the Law on safe drinking water is not able to establish national rules for primary drinking water for organic chemicals. Since 1975 E.P.A. I issued a very short list of maximum contaminant levels (MCls). The list includes some pesticides and herbicides, a small amount of inorganic chemicals, standard for coliform bacteria, turbidity, radionuclides, and since 1979 – trygalametany. A total of 130 priority pollutants.
Amazing fact is that there are currently over 100,000 chemicals released to the environment, and about 1,000 additional chemicals are added every year. Nevertheless, EPA only tests about three percent. Thus, municipal water supply services is obliged to carry out checks on the contents of only 130 chemicals, when in some parts per million or billion may be present hundreds and even thousands of chemicals that can be dangerous to humans. How complex chemical combinations possible with the list of the 100 000 individual chemicals?
Here is an example of how terrible can be the answer. Vodokanal added chlorine in the water as very necessary for destroying the disinfectant in water born viruses and some bacteria. Most urban water contains a certain degree of humic acid that is formed during the decay of plant and animal matter. In addition to that of chloro & # 39 is a known carcinogen, when chlorine is in contact with humic acid, four separate carcinogens are called trygalametany (THMs). Combine only two and get four! Now, imagine the possibilities of mixing 10's of thousands in your drinking water.
Water from the & # 39 is an essential element to support life, second only to oxygen. We can live 40 days without food, but only about 6 days without water. The water serves three main purposes in our bodies. 1. It controls body temperature; 2. It carries the nutrients in the food we eat, to every cell in our body; 3. Water and replaces fluids such as blood plasma, lymph, digestive juices, bile, etc. It washes and bathes every cell of the body, washing and carrying away the waste and toxic poisons. When the water is so important for our health and well being, whether we drink the healthiest water worth? What would it be, you ask? Distilled water.
