Be Concerned, Be Very Concerned

In 1950, the US withdrew 12 trillion gallons of water from the ground; in 1980 this figure doubled and continues to grow at an alarming rate. The Ogallala Aquifer is being depleted at a rate of 12 billion cubic meters (420 billion cubic feet or 9,729,000 acre feet) per year, amounting to a total depletion to date of a volume equal to the annual flow of 18 Colorado rivers (4,000 cubic feet ). per second).

Time Magazine reported, “The Ogallala Aquifer is being absorbed and drying up! Some estimates say it will dry up within 25 years. Many farmers in the Texas High Plains, who rely especially on groundwater resources, are now moving away from irrigated agriculture as they become aware of the dangers of over-pumping. The aquifer stretches from South Dakota through Nebraska, where two-thirds of its water lies, to Wyoming, Colorado, Kansas, Oklahoma, New Mexico and Texas. For the past three decades, farmers have been pumping water from the Ogallala as if it were inexhaustible. The annual overdraft of the amount of water that is not being replenished is nearly equal to the flow of the Colorado River. A report by the engineering firm, Camp, Dresser and McKee, estimates that by 2020 about 5.1 million hectares of irrigated land dries up.

Today, the American Southwest is the most irrigated area in the world, transforming a desert into a veritable Garden of Eden. However, this heavy irrigation can destroy the soil by salt leaching. The 1,400-mile-long Colorado River is the lifeblood of 11 million people from Denver to San Diego. In fact, today it irrigates 1.5 million hectares of prime agricultural land. This magnificent river is slowly being poisoned by salt loading from western saline runoff and salt concentration caused by evaporation and increased use of the river in the seven states it serves. Salt levels have reached more than 800 milligrams per liter and are expected to reach 1200 m/l in the near future. The EPA’s maximum safe level for drinking water is 500 parts per million, above 500 ppm is considered unsuitable for drinking. (This translates to teaspoons of salts per gallon of water.) In addition to depleting groundwater resources, there is less precipitation falling on land and more in the ocean, due to shifting air currents and changes in global weather patterns.

WHAT COULD BE WORSE?

As if a declining water supply wasn’t bad enough, we’re now rapidly destroying what little water we have left with hazardous waste. Toxic chemicals in thousands of hazardous waste sites across the country continue to seep into the nation’s subsurface, contaminating the soil and groundwater and poisoning the air. The US General Accounting Office says the Superfund program will be required to clean up more than 10,000 sites, which appears to be an insurmountable task at the moment. Six billion tons of solid and hazardous waste are generated in the United States each year. 400 million pounds of toxins are discharged into our waterways each year by American industry, according to data from the Environmental Protection Agency (EPA). A recent study predicts that, at the current rate, it will take between 30 and 35 years and $253 billion to clean up most of the nation’s known and as yet undiscovered toxic waste sites. The EPA projects it will need to remediate at least 294,000 hazardous waste sites — and that number could go as high as 355,000.

DEFENSIVE APPROACH?

EPA in implementing the Safe Drinking Water Act has failed to establish national drinking water regulations for organic chemicals. Since 1975, the EPA has issued only a very short list of maximum contaminant levels (MCls). The list includes some pesticides and herbicides, a small number of inorganic chemicals, a standard for coliform bacteria, turbidity, radionuclides and, since 1979, trihalomethanes. A total of 130 priority pollutants.

The surprising facts are that there are currently more than 100,000 chemicals that have been released into our environment, with approximately 1,000 additional chemicals added each year. Yet the EPA only tests about three percent of them. In summary, municipal water utilities are required to test for levels of only 130 chemicals when there may be hundreds or even thousands of chemicals present in some parts per million or billion that could be potentially dangerous to humans. How many chemical compound combinations are possible with a list of 100,000 individual chemicals?

Here’s an example of how scary the answer can be. Water utilities add chlorine to water as a much-needed disinfectant to kill water-borne viruses and a number of bacteria. Most city water contains some amount of humic acid formed from decaying plant and animal matter. In addition to chlorine being a known carcinogen, when chlorine comes into contact with humic acid, four other individual carcinogens called trihalomethanes (THMs) are created. Combine just two and get four! Now imagine the possibilities of mixing 10’s of thousands into your drinking water.

Water is the single most important element for sustaining life, second only to oxygen. We can live 40 days without food, but only about 6 days without water. Water serves three main purposes in our body. 1. Controls body temperature; 2. It carries the nutrients in the foods we eat to every cell in our body; and 3. Water replaces bodily fluids such as blood plasma, lymph, digestive fluids, bile, etc. It washes and washes every cell of the body, flushing out and removing waste materials and toxic poisons. If water is so vital to our health and existence, shouldn’t we be drinking the healthiest water possible? What would that be, you ask? Distilled water.
