Water Treatment

Committed to the Purity of New Hampshire’s Water

Water treatment services at your New Hampshire home or industrial facility help ensure the water you drink, bathe or cook with, and simply use day in and day out is clean, safe, and healthy for you and your family. Impurities can exist in any type of well, whether private or municipal, so it is crucial to have the proper systems in place to prevent bacteria, chemicals, and other types of contaminants from infecting your water.

Some contaminants, such as coliform, radon, iron, and arsenic, among others, are dangerous for human and animal consumption. Arsenic and radon, for example, are found naturally in groundwater and bedrock. Because these contaminants are so commonly found in New Hampshire, the state recommends annual testing of private wells, while an elected government official typically manages the water treatment of public municipal systems.

Other contaminants are not necessarily harmful, but may cause problems such as foul odor or bitter taste. While the public municipal systems are managed by the state, homeowners with private wells are responsible for their own water treatment and testing.

Water treatment can be a complex and confusing process. Which process is right for your water? What are the differences between a reverse osmosis water filter and an ultraviolet filter, and why do those differences matter? Should you install a point-of-use water treatment system or a point-of-entry system? What is the best way to treat iron contamination?

Let Capital Well’s Clean Water professionals clear up the confusion and clean up your water.

  • George Craggy

    Jonathan, I wanted to drop a couple of lines to tell you how satisfied and happy that I chose Capital Well Co. for my water needs. From your lead man Steve to your drill people, your plumbing guy and your guy on the back hoe. Everyone that cast a shadow on my door threshold were polite, professional and willing to take the time to explain and answer my questions; which were many . Jon, it was my pleasure to meet you today and pleased that you came by for a follow up visit and explain how the heater works. SO...if I get a chance to tell everyone that needs a new well, I definitely will. It is apparent there is no "I" in your team . Thank you everyone.
  • Richard Meaney

    Mr. Swain, Thank you so much for the service Capital Well provided at my home today. I left a message with you at the behest of Ed Monty. I received a prompt phone call from Greg to arrange for a service call and to discuss what might need to be done. Promptly at (actually a few minutes before) the scheduled time, Bobby showed up to perform the service. Bobby was excellent at explaining the service, why some things were needed and how the well and pump worked, and answered all of my questions to my satisfaction. All in all, this was a very positive experience for us. Thanks to you and the people at Capital Well for prompt, courteous, and efficient service.
