Nashua NH water quality.

Nashua, New Hampshire is a small city that sits along the Merrimack River, rich with historical buildings and a rising restaurant scene. It’s a central spot to surrounding towns in New Hampshire and Massachusetts alike, with over 80,000 residents and 12,000 companies. Last year, a major sewage spill plagued the Merrimack River, possibly impacting hundreds of thousands of residents that live along it between NH and MA.

Merrimack River
Brown water flows out of the mouth of the Merrimack River following a tropical storm in 2011. Heavy rainfall, snowmelt, and aging infrastructure regularly leach raw sewage into the the river. Many cities in New Hampshire and Massachusetts draw drinking water from this river. Source.

An estimated 600,000 people’s drinking water is sourced from the Merrimack River before going through a vigorous treatment cycle, spanning 117 miles between New Hampshire and Massachusetts. In 2018, an unfortunate dumping of 800 million gallons of raw or partially treated sewage water burst into the Merrimack River by consequence of aging pipes that had neglectfully been left unsealed in five separate locations. Contamination by untreated sewage is full of pathogens from bacteria that can cause serious illnesses such as dysentery, hepatitis and other gastrointestinal diseases for those who come into direct contact with the water by swimming, kayaking, or other river water-related activities. Along with consequences that pose risk to human health, toxic algae blooms can form as a result of sewage pollution, devastating fish and marine life by cutting oxygen in water.

Pennichuck Water is the main water treatment facility for greater Nashua, with water sourced from various rivers such as the Merrimack River, rainfall drains, lakes, ponds, and wells. Surface water is highly susceptible to contamination by factories, hazardous waste, and environmental factors. In order to offset contamination and transform the collected water to meet regulations standards, chemical treatment is used to balance the dangerous substances with less dangerous substances until the water is safe enough for human consumption.

Nashua River ran red with industrial contaminants in 1967
Much progress has been made since the Nashua River ran red with industrial contaminants in 1967. However, the unsafe levels of invisible, odorless PFAs now being shown in Nashua’s drinking water show that New Hampshire’s water supply still has a long way to go. Source.

Some chemicals can be more challenging to remove, such as PFAS (per- and polyfluoroalkyl substances), which are man-made chemicals typically found in plastics, food packaging, and non-stick cookware.
PFAS are often linked to:

  • Low birth weight
  • Thyroid hormone disruption
  • Compromised immune systems
  • In some cases, cancer
The level of PFAS in Nashua water has only increased in recent years
As more is learned about the hazards of PFAs, the CDC has lowered what is considered the acceptable level of exposure. Meanwhile, the level of PFAS in Nashua water has only increased in recent years. Source (PDF).

According to the most recent water report by Pennichuck Water, Nashua’s public water is above the CDC’s health limit of 11 parts per trillion for PFAS, with Nashua’s water at 16 parts per trillion. This is a significant increase from recent years, with 9 parts in 2018 and only 5.2 in 2017. Currently, Nashua’s northern neighbor Merrimack is going through its own water crisis upstream. The likelihood of Nashua’s PFA contamination crisis continuing to worsen in the coming years is very high as polluted surface and groundwater seeps downstream from Merrimack.

Nashua PFAS Contamination Levels

  • CDC Proposed Acceptable Levels of PFAS: Below 11 parts per trillion
  • Nashua Levels of PFAS: 16+ ppt as of 2018

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 Whole House Water Filtration System 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.

Contaminants found present in the water that were within regulations are:


A dangerous heavy metal that leaches into the water supply after being processed at treatment facilities due to an antiquated distribution infrastructure that contain lead pipes, often found throughout New England.

Used to chemically treat contaminated water and control microbes. Unfortunately, chlorine is known to have adverse effects to human health as well.
