Housing Age Profile
Because the majority of Oyster Bay's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1967 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in Oyster Bay were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Oyster Bay: Lead Risk & Vulnerable Populations
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.
Routinely in Oyster Bay, where 84% of housing predates the solder ban and aggregate utility readings hover near the federal threshold, a faucet-level draw functions as a standard household step for families with small kids.
