Keene is the largest city in the Monadnock Region and sits along the Ashuelot River in southwestern NH. Much of the city is on municipal water, while the surrounding rural areas and outlying neighborhoods rely on private wells. The water picture in the Monadnock Region is distinct from the rest of the state.

What Keene homes tend to deal with.

Monadnock

Keene's municipal water meets federal standards but comes with the usual chlorine residual and disinfection byproducts that some homeowners prefer to address at the point of use. Older parts of downtown have pre-1986 housing stock where interior lead plumbing can contribute lead at the tap. On the private-well side, the Monadnock Region bedrock is related to but distinct from the southern NH granite belt. Arsenic can show up in individual Keene-area wells and should always be tested, though at generally lower regional intensity than Bedford or Merrimack. Iron, manganese, and hardness are the routine findings in private wells, especially in the lower-lying areas along the Ashuelot. Radon in water is worth testing for given Cheshire County's bedrock. PFAS findings have been documented across NH at low levels in scattered private and public systems, so baseline PFAS testing is worthwhile for any private well.

What we install here.

Keene well homes typically get a full panel first, then treatment tailored to the findings. Whole-home iron and manganese filtration, softening, and a kitchen reverse osmosis unit are the most common installs. Arsenic removal and radon aeration are added when testing calls for them. Municipal customers do well with whole-home carbon plus point-of-use reverse osmosis.
