PFAS in your water

Your regional water experts for water quality issues in New Hampshire

This is an emotional issue, and we will support you in making as informed a decision about testing for and treating PFAS as possible. We want to help you trust your water again. All our Water Specialists are certified with the Water Quality Association. We have the most experience solving for tough health-related contaminants across this region. Like most of the health related contaminants we deal with, there is no taste, odor or color associated with PFAS, so the only way to know is to test.

Our drinking water systems and whole-house treatment systems have come back with non-detectable PFAS and other related contaminants. Contact us today to set up testing or discuss your options. If you are at a point where you would prefer to just ask some questions about PFAS by phone or email, we are happy to answer all of them!

 Trustindex verifies that the original source of the review is Google. 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”. 😊

He was professional and went above and beyond. I've recommended this company to others, and will continue to do so!

 Trustindex verifies that the original source of the review is Google. 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.

 Trustindex verifies that the original source of the review is Google. 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.
