Housing Age Profile
Because the majority of Martin's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1986 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in Martin were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Lead Exposure Risk for Children in Martin
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 60% 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 Martin address.
