How Old Is Greenville Junction's Housing Stock?
With 80% 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
When a city's housing median build year is 1963, as in Greenville Junction, the implication for water quality research is straightforward: municipal-level data captures what leaves the treatment plant, but household plumbing from before 1986 determines what actually arrives at the tap. In cities where older housing predominates, that gap between system-level and household-level data is widest.
Over half of homes in Greenville Junction were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Greenville Junction: Remediation Cost in Perspective
In Greenville Junction, property wealth outpaces what documented remediation typically demands — the equity burden lands well within the low tier.
Remediation costs in Greenville Junction are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 17% below the Maine average.
Protecting Children from Lead in Greenville Junction
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.
When older housing represents 80% of the local inventory or aggregate readings approach the federal action level, an in-home check becomes the standard way to translate citywide averages into the specific reality of an individual Greenville Junction address.

What You Can Do in Greenville Junction
