Analysis

What to know about Pittsfield's water

Pittsfield ranks #57 out of 119 cities in New Hampshire for water quality, placing it mid-range in the state.

The city draws from surface water sources, which are more susceptible to seasonal runoff and agricultural contamination, requiring extensive multi-barrier treatment including coagulation, filtration, and disinfection.

Lead levels exceed the EPA action level of 15 ppb, which typically indicates aging lead service lines or lead solder in the distribution system. An NSF 53-certified filter is strongly recommended for drinking and cooking water.

As a small community water system, Pittsfield may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.
