Housing & Infrastructure in Lempster
With 72% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.

Housing Age Profile
Federal plumbing rules changed in two stages — lead pipes were phased out before 1970, and lead solder was banned in 1986 — but in Lempster, where the median build year is 1974, most of the housing was already in place before those rules took effect. The materials installed under older standards remain embedded in a substantial portion of the residential inventory today.
Over half of homes in Lempster were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Lempster Homeowners
When estimated remediation is placed alongside median property values in Lempster, the resulting ratio is low — a finding consistent with a household financial perspective where documented issues can be addressed without a meaningful impact on overall equity position, making this market one of the more favorable contexts for remediation planning.
Remediation costs in Lempster are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 41% below the New Hampshire average.
Lead Exposure Risk for Children in Lempster
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Wherever 72% of local housing was built before solder rules changed — as is the case in Lempster — a faucet-level sample closes the gap that aggregate utility data cannot.
