How Old Is Hialeah's Housing Stock?
Median build year of 1975 means many homes predate lead paint and lead solder regulations. Consider testing if your home has original plumbing.

Housing Age Profile
The year 1986 marks a critical threshold in residential plumbing safety: that's when the federal government banned lead solder from new construction, closing a major pathway for lead entering household drinking water via pipe joints. Hialeah's median build year of 1975 signals that most of the city's housing was built under the newer standard. The distribution above tells the full story - the post-1986 majority lowers aggregate risk, but the pre-1986 share still deserves scrutiny from anyone living in or purchasing an older home.
Most homes in Hialeah were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Protecting Children from Lead in Hialeah
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.
Lead risk in Hialeah appears low overall, but individual homes may differ. Testing is the only way to confirm your water's lead content.

Historical Flood-Claim Evidence for Hialeah

How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure.
