Housing & Infrastructure in Silver Lake
With 56% 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
For residents trying to assess tap water risk in Silver Lake, the median build year of 1987 is the starting context. It signals that a majority of homes were constructed before 1986 — the year federal rules prohibited lead solder in new plumbing — and that a significant share likely predates 1970, when lead pipes were still a common choice for residential service connections. Neither risk tier is rare in this housing inventory.
Over half of homes in Silver Lake 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 Silver Lake Homeowners
Within the Silver Lake market, estimated remediation claims a small portion of typical property equity — the financial burden is proportionally low.
Remediation costs in Silver Lake are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 6% above the New Hampshire average.
Lead Exposure Risk for Children in Silver Lake
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.
Pulling a tap sample fills the gap that utility data cannot close, particularly here where 56% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Silver Lake.

What You Can Do in Silver Lake
