How Old Is South Londonderry's Housing Stock?
With 50% 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.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Because the majority of South Londonderry's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1984 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in South Londonderry were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

South Londonderry: Remediation Cost in Perspective
In South Londonderry, the equity impact of remediation is proportionally small — not the kind of financial commitment that rises to the level of a genuine planning constraint, but a minor share of what most properties here are worth.
Remediation costs in South Londonderry are relatively low compared to home values. The $1,200–$3,300 estimated range is a small fraction of median property value. Home values are 6% below the Vermont average.
Protecting Children from Lead in South Londonderry
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.
Older stock in South Londonderry represents 50% of the inventory, and citywide monitoring runs at or above the federal action level — making an in-home read a standard household-level step.
