Reverse osmosis has been around for quite some time. It is so far the most effective and viable technique of purifying water supply to make it safer from drinking and general consumption. While it is a common knowledge that the planet is two-thirds water, it is also a fact that many nations around the globe and suffering from lack or significant depletion of available natural drinking water. Other than that, reverse osmosis is also identified as the best method to make sure water supplied to households are safe and are free from any unwanted chemicals and impurities.
The process of reverse osmosis is also becoming more popular and useful in the United States, not because there is a great depletion of drinking water but now more because the technique could help assure overall quality and safety. Many states are now adopting the use of reverse osmosis technology to make sure drinking water supplied to every American home would not bring about adverse and unlikely health hazards.
There is a spreading rumor that there is a high volume of contraceptive chemicals that are found in drinking water in several cities and states in the US. Tests have proven that this is more than just a speculation. It has been determined that there is actually trace amounts of artificial birth control substances and other medications in water supplied to households and industries. However, there is still a considerable debate whether this would be taken as a general health risk.
The US Geological Survey in 2008 tested water in about nine states across the US. It found that there are about 85 man-made and artificial chemicals in water from the faucet. A separate report from the Associated Press said minimal amounts of numerous medication substances combine with tap water that is supplied to some 46 million US citizens. However, it has also been found that the chemicals and substances are very much diluted that they are not posing any potential to induce any slight health effect.
Among the dangerous contaminants found in tap water is estrogen, which is inadvertently accumulated and released into sewerage from urine of women who are taking contraceptives or birth control substances. This form of estrogen could wreak havoc on reproduction of fish. It could also cause growth of breast cancer cells in men and women. There are many other contaminants found in tap water flowing from household faucets. Health experts warn that exposure to such impurities could pose still unknown health dangers and risks.
Initially, experts assert that basic burden of protection frequently lies to the hands of users. Thus, there are now many kinds of small-scale or in-home filtration systems available. It is surprising how sales of such products are rising, even if there are no regulatory approvals or proofs that they work. It shows that many American households are getting more concerned now.
The best way to filter out such impurities is of course reverse osmosis. There are now portable devices available for small-scale water filtration intended for household use. Many water distributors are also investing in facilities that would carry out reverse osmosis techniques to make sure water supplied to consumers are completely free from hazardous and dangerous chemicals and impurities, even in trace amounts.
