How Old Is Tangipahoa's Housing Stock?
With 63% 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
Heavily weighted toward older construction, Tangipahoa's housing stock carries a median build year of 1972. That profile puts a majority of homes in the era when lead-soldered copper plumbing was standard practice.
Over half of homes in Tangipahoa were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Protecting Children from Lead in Tangipahoa
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 63% 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 Tangipahoa address.

Climate-Related Water Risk for Tangipahoa
