Water Filtration Services in Hanover, New Hampshire

The Upper Valley around Hanover has its own water profile. Bedrock wells here can test elevated for arsenic, though the regional pattern is less concentrated than the southern NH granite hotspots. Radon in water is a concern given the area's geology. Iron and manganese are common in both deep bedrock and shallower wells, particularly in lower-lying areas near the Connecticut River. Hardness is widespread. The Connecticut River watershed also brings occasional agricultural and historical industrial considerations for surface-influenced wells. Hanover's municipal supply meets federal standards, but customers still deal with chlorine residuals and, in the older parts of town, legacy in-home plumbing that can contribute lead at the tap. PFAS findings have been documented across the Upper Valley at low levels in various public and private systems, so baseline PFAS testing on any private well in Hanover is a reasonable step.
