How Old Is Irvington's Housing Stock?
With 55% 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
What does a median build year of 1986 mean for water safety in Irvington? It means the majority of the city's residential plumbing was installed before 1986, when lead solder was federally banned, and a large share may predate 1970, when lead pipes were commonly used — making plumbing age a central variable in household-level lead risk across much of the city.
Over half of homes in Irvington were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Irvington: Remediation Cost in Perspective
Is remediation financially manageable for Irvington homeowners? At a moderate equity share, generally yes — with deliberate budgeting ahead of time.
Remediation costs are moderate relative to home values in Irvington. The estimated $800–$2,600 range is manageable for most homeowners but still worth budgeting for. Home values are 4% below the Kentucky average.
Protecting Children from Lead in Irvington
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.
Before the federal solder ban, lead solder was a routine plumbing material, and 55% of the Irvington inventory was built in that earlier era — a share large enough to move household-level reads onto the standard list.

Climate-Related Water Risk for Irvington
Irvington carries a limited flood exposure profile, with claim volume and flood zone coverage both remaining modest. That limited footprint keeps flooding well below the severity thresholds where treatment infrastructure comes under meaningful stress.
Irvington has a relatively low flood history with 4 FEMA claims on record. While risk is limited, severe weather events can still impact water infrastructure.
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. Flood damage can add significantly to the estimated <strong>$1,600</strong> remediation cost per household.
