Water Quality Report for Merrimack, New Hampshire

Merrimack is currently undergoing a water crisis.

We hate to sound like alarmists and will do our best to present the facts as clearly and straightforward as possible. The PFA contamination of Merrimack's water table is a true crisis and requires immediate and decisive action.

First Congregational Church, Merrimack NH
The town of Merrimack, New Hampshire has a population of well over 25,000 and is no stranger to the side effects of pollution in it's water sources.

Incorporated in 1746, the Town of Merrimack has a long history of its realationship of industry and its water supply. Both the Souhegan River and the Merrimack River make their way through portions of the town of Merrimack. And both of these rivers have a long story of abuse stemming from the industrial revolution through the current day. Industrial pollution from the mills and factories in Manchester and the dumping of raw sewage have tainted the rivers for generations.

While many improvements have been made in the past few decades, the groundwater in Merrimack will be recovering for decades to come. Unfortunately, spills and industrial accidents continue to delay the renewal of these resources.

Beyond the chlorine, lead, and other contaminants frequently found in New Hampshire municipal water, Merrimack is reeling from a 2016 PFOA contamination. One of the primary concerns about PFOA is that once they are released into the environment they don’t easily go away.

Merrimack PFOA Contamination Levels

  • CDC Proposed Acceptable Levels of PFOA: Below 11 parts per trillion
  • Merrimack Levels of PFOA: 19+ ppt

PFOA is a man-made chemical used in making plastics and other consumer goods. Unfortunately, during the manufacturing process, large amounts of PFOA were dumped into the soil, emitted into the air and poured into the water surrounding factory sites. Recent findings by the Center for Disease Control (CDC), have found that PFOA contamination is a much more serious threat to health than originally thought. New research finds that even very tiny amounts are harmful.

PFOA is a health concern because it can stay in the human body for long periods of time. Once in your body, it takes approximately 4 years for the level to go down by half, even if no more is taken in. Studies have found that prolonged exposure to PFOA pose the following health risks:

  • Developmental effects
  • Cancer
  • Liver damage
  • Immune disorders
  • Thyroid imbalance
  • Cardiovascular concerns

Following a water test by NH Tap and upon detection of PFOA, a custom water treatment plan will be designed to purify and rid it of dangerous impurities. The NH Tap MainFrame™ water purifier is the best defense against PFOA, a 3-stage filtration technology that will contain and remove toxins before circulating into the home. The MainFrame™ performs an automatic regeneration cycle to clean and restore capacity, so you may rest knowing NH Tap is continually providing your home access to safe, toxic-free water.

To protect their health, residents of Merrimack laudably voted to install industrial filtration systems on their municipal aquifers. However these filtration systems will not be online for several years at best, and PFA levels are already far beyond "acceptable" levels. Meanwhile, Boston University is planning a study on the long-term effects of this contamination on Merrimack children.

NH Tap's Recommendations

Let's get the elephant out of the room first. We understand possible skepticism over a water filtration company raising the alarms about a water crisis. NH Tap does stand to profit by selling a lot of home water filtration systems because of the PFOA contamination in Merrimack. As a business, we do intend to be profitable. But only by providing the best solution to New Hampshire's complex water problems. Our mission is truly to provide the residents of New Hampshire with undoubtedly pure drinking water at a great price.

As such we have developed simplified systems at multiple price-points to make PFOA-free drinking water an affordable option for those affected by this tragic groundwater pollution. NH Tap designs and manufactures whole-home water purification systems tailored to the unique chemical make-up of New Hampshire town water. We believe clean water is a basic necessity for quality living, and have focused our business on providing the town of Merrimack access to the water they need to thrive.

Should your well show any signs of contamination, NH Tap can put together the right technology to fix your bad water for good.
