This is based on the apparent lack of confidence in the quality of water provided by the municipal water provider or from the private well. An argument can be made that this may have some scientific validity for two reasons:.
These are tiny concentrations of mainly organic compounds which go down the drain from all activities. These contaminants ultimately end up in drinking-water supplies, including surface water as well as aquifers. The concentrations are measured in parts per trillion equivalent to one second in 32, years , but it is estimated that there are as many as 85, different chemicals in our drinking water.
There is no doubt that RO drinking water will improve the quality of water supplies from both of the above issues. The problem is that not all bottled water is made from RO permeate; some is advertised as spring water and may even come from a municipal supply.
The water has probably been ozonated when the bottle is filled, so it should be free of pathogenic microorganisms, but that may be the only treatment it has received. Unless the bottle label states the source and treatment of its contents, it is difficult to determine exactly the quality of this product.
There has been concern about various components of the plastic material that may be leached into the supply and contaminate from within. Another factor is the cost of bottled water. Compare this to the current price of gasoline. And, of course, consider the plastic pollution resulting from all these bottles. It is estimated that Americans discard million water bottles per day.
Because we recycle only nine percent of our trash, the vast majority end up in a landfill, where it will take years for them to break down. Thanks to the benign characteristics of plastic, they only break into tiny particles, most of which end up in the ocean. It is predicted that by , the weight of plastics in the ocean will exceed the weight of all fish.
Conclusion Water quality around the globe continues to deteriorate due to increased stresses placed on the natural water sources. Contaminants that have just recently been identified add to the problems we already face and fortunately, water purification devices, especially reverse-osmosis drinking-water appliances are relied upon to provide safe, high-quality life support water.
Although public utilities enjoy a splendid reputation for dependable water service, they are sometimes left with no choice but to decentralize when a contaminant exceeds the US EPA acceptable maximum contaminant level MCL.
When this happens, consumers are notified that supplemental treatment is required to ensure safe drinking water. In defense of the US water-treatment industry, our collective efforts in water conditioning and purification technologies have reduced waterborne illness and disease drastically since before the turn of the 20th century. We must refute the misinformation so prevalent in the media with facts and figures, not with generalities, myths and opinions.

The water crisis in Flint, Michigan involving lead prompted increased scrutiny of public water around the country. However, with a reverse osmosis system, you can drastically reduce those unwanted contaminants. The special membrane filters out the vast majority of microscopic organisms and heavy metals.
Learn more about how reverse osmosis systems work. Water softeners are specifically designed to remove hard minerals from the water. Water softeners solve a lot of hard water problems , but they are not meant to for purification.
However, not everyone enjoys the taste of softened water. Remember, in the ion exchange process your water softener uses, hard minerals are replaced with sodium molecules. You could still have a high level of total dissolved solids, which will impact the taste. Reverse osmosis filters out the sodium that your water softener adds. A reverse osmosis drinking water system partnered with a water softener allows you to enjoy the benefits of both soft water and purified drinking water.
Plus, R. Bottled water is expensive. Those plastic bottles create a lot of waste as they all too often go unrecycled and end up in landfills.
