The metropolitan area of Manchester brings some good things to the table when it comes to water purity. Unlike their neighbors in Milford, Nashua, and Merrimack, Manchester Water has traditionally sourced their water from a protected body, Lake Massabesic, and have purified it at the local treatment plant.

But with a growing population, taking on other city’s water needs, and a recent issue with the infrastructure, Manchester is going through some changes that her residents should be watching.

Currently, the water issues include —

  • An aging sewer system delivers more contaminants to the city residents.
  • Wastewater and sewage overflow that pollutes the Merrimack River, adding to the current water crisis downstream. (Bacterial contaminants in the water have been known to be at five times allowed levels.)
  • A plan to add the Merrimack River as well as a new radial collection site that will source groundwater for Manchester water.
  • The statewide problems with PFAS, carcinogens that can cause liver, kidney, immune, reproductive, and overall physical harm.

Manchester has a large problem with sewers being connected to stormwater drains. These old sewer systems collect both stormwater and sewage, and during storms with high water levels, usher raw sewage right into the Merrimack River.

While Manchester (and the other cities it serves) have not had to drink from this river, it oddly decided in 2019 to put in a facility to draw water from this source.

The city and Manchester Water Works are purifying the water, are testing it over 500 times each week for safety standards, and are creating plans to fix the wastewater issues. But despite the best efforts, clean water continues to be a stressor for many NH residents. Regardless of the purity of the source, the water companies have to insert a host of less dangerous chemicals to remove the highly dangerous ones from the water.

And while this solution falls within legal limits, we believe there’s a better and safer water solution to fix your water issues for good.

Contaminants found in Manchester, NH water.

Common contaminants in the city water supply include:

Bromodichloromethane and Chloroform

Formed when chlorine and other disinfectants treat the water, these byproducts are a carcinogen that can impact fetuses during pregnancy.

A radioactive element, it can cause bone and other cancers. It occurs naturally in groundwater, as oil and gas extraction impacts the concentrations.


This is a carcinogen that passes to drinking water through pollution as well as naturally-occurring minerals in groundwater.

Other Detected Contaminants

Aluminum, Barium, Chlorate, Fluoride, Manganese, and other contaminants are impacting Manchester water. While they may fall under legal levels, trace amounts can still negatively impact health, particularly with young children, immunocompromised individuals, and aging adults.

Substances added to Manchester, NH water supply.

To combat hazardous pollutants and counteract adverse effects, Manchester’s town water is has a seven-step process to chemically adjusted its water supply. This includes adding the following components —

  • Aluminum Sulfate
  • Sodium Hypochlorite
  • Aqueous Ammonia
  • Phosphoric Acid
  • Fluoride

These chemicals, while necessary to clean the water, don’t leave your water chemical-free.
