Arsenic in your water

Your regional water experts for water quality issues in New Hampshire

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 5 houses on a private well in 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.

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.

Arsenic is colorless, odorless, and tasteless. It’s presence can only be determined by testing. Because every home is different, in order to recommend a system for your arsenic problem, we offer a free site evaluation, do some testing, learn about your water use patterns and your preferences.

Technician took the time to explain how my entire system worked so I would finally understand. I’ve had several technicians come out, never had a bad experience, but the guy they sent yesterday actually seemed to care about his job deeply. I’m sure the fact that he takes the extra time frustrates the main office, but they should give this guy a raise. Forgot his name but he’s 6’3”. 😊

Greg was very informative during our first yearly check of our RO water system and answered any questions I had. He was professional and went above and beyond. I've recommended this company to others, and will continue to do so!

I received a call telling me that the technician would late. Greatly appreciated that, I hate waiting. Greg was a little early, also fine. Everything worked out well and he gave some tips for in the future protecting the pipes. Very clear with directions.

The technician (Greg) let me know he was running ahead of schedule, which worked with my schedule even better than the originally scheduled time! He did the maintenance thoroughly and quickly and explained the post-sanitizing process very clearly.
