Bacteria can be found as a naturally occurring part of most, if not all, water sources. And most species of bacteria pose little harm when it comes to the health of human beings. But if a certain variety known as coliform bacteria happen to take up residence in your well water, then you and your family stand a real chance of becoming very sick.
To ensure that your well water remains free of coliform and other nasty bacteria like it, you will need to use some type of disinfection. The simplest way to disinfect water is to boil the water that you will use for washing, cooking, or drinking. Yet to boil all of the water that enters in your home would end up costing a small fortune.
A more cost-effective method involves the use of ultraviolet (UV) light. UV light is distinguished by its incredibly short wavelength - so short that UV rays cannot be seen by human eyes. Its tiny length gives UV rays their incredible disinfecting power, making them capable of passing right through the cell walls of bacteria and viruses and into their DNA.
Ultraviolet light causes irreparable damage to the genetic material of bacteria, leaving them unable to reproduce - and therefore unable to make you and your family sick. By passing water through a UV disinfection system as it enters your home, you can ensure the cleanest possible drinking water.
After learning about the effects of UV light on bacteria, many people harbor concerns about its effects on humans. You have nothing to worry about in this regard. While direct exposure to UV rays is obviously dangerous for humans, water that has been treated by UV light will cause no such harm. And UV light won't lead to any noticeable changes in the appearance or taste of your water.
