But no matter where you live in the city, water quality remains an issue. We will review the known contaminants in the local community and some options you can consider. The NH Tap team is located in Milford, and we’re passionate about helping our NH families and businesses mitigate water problems with the best whole house water filtration systems for Derry to avoid potentially life-altering issues.

Water quality in the Derry, NH area.

We were pleasantly surprised by how easy it was to navigate the local water service’s information! The town has both city water and well water — and back in 2010, the town put together a plan to protect the groundwater. Derry gets its city water from Manchester Water Works, and a few communities have a shared bedrock system.
The city water should be mostly safe, getting rid of big offenders like bacteria, chemical runoff, and other natural elements. But regardless of your system, various harmful chemicals can still come through city water at “legally” safe levels, including chlorine as well as natural elements.

If you’re on well water, it’s a completely different story. With the ongoing issues of PFAS and arsenic, NH Tap recommends that most NH well water owners get their water tested often (every 1-2 years) or get a water filtration system to ensure they have a safe supply.

The Environmental Working Group (EWG) provides a water analysis per zip code based on their findings over the past few years. The EWG has listed eleven pollutants penetrating the water supply in Derry, NH. Some of the offending cancer-causing chemicals include —

  • Perfluorooctanoic acid (PFOA)* (249x higher than recommended)
  • Haloacetic acids (HAA9)† (51x higher than recommended)
  • Haloacetic acids (HAA5)† (44x higher than recommended)

Since some of these chemicals pose an immediate risk, specifically PFOA, be sure to organize your testing for city water or well water as soon as possible to avoid any health problems.
