From start to finish they exceeded my expectations. My hard earned money was well spent on my new Kinetico system, making our water safer for my family. I am stunned by their attention to detail and fantastic customer service. I would give more stars if I could!

Water treatment may seem like a small piece of the puzzle, but it’s actually critically important to our work. I wouldn’t choose any company other than Secondwind.

THANK YOU!!! for everything. You and Shane were both very professional and excellent at explaining and answering questions. I am really impressed with how simple and self explanatory the system is. The warranty and your customer service are added reassurance. I wish I had found you years ago.

Frequently Asked Question

Why is there Arsenic in my water?

Arsenic in water in this region is natural; it is an element of our earth’s crust. New Hampshire has a lot of arsenic in the water. In fact, 1 in 4 houses on a dug well in the southeast part of the state have actionable levels of arsenic in their water.  More and more attention is being called to this very real water quality problem in the region.

What are the dangers of having Arsenic in my water? 

Long term exposure to arsenic has been related to cancers, cardiovascular disease, immunological disorders, diabetes and neurological issues.  Arsenic is described as an “accumulative enabler” – its health effects can accumulate over time.  The health issues with arsenic have been shown to be primarily related to drinking rather than skin contact, so your first decision is whether you treat the drinking water, at “point of use,” or the whole house or whole facility water, known as “point of entry.” Only you can make the decision.
