How Old Is Littlerock's Housing Stock?
With 61% 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.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Because the majority of Littlerock'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 Littlerock were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Littlerock: Remediation Cost in Perspective
Because property values in Littlerock comfortably exceed estimated remediation costs, the equity impact here is proportionally small.

Protecting Children from Lead in Littlerock
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 Littlerock, where 61% 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.

How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies.

Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.
