Delphia Infrastructure Age

Housing Age Profile
Pre-1986 plumbing is not a rare legacy case in Delphia - it's the dominant profile. The median build year of 1975 indicates a housing stock where lead-soldered copper joints are a common structural feature of residences across the city.
Over half of homes in Delphia were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in Delphia
Because property values in Delphia comfortably exceed estimated remediation costs, the equity impact here is proportionally small.
Remediation costs in Delphia are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 57% below the Kentucky average.
Delphia: 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.
Despite citywide averages serving as the standard public reference point, those aggregates cannot resolve what is happening at one specific faucet - and where 68% of Delphia homes come from before the solder rule or where utility samples sit at or above the action mark, the gap between system data and faucet reality matters more than it does in lower-exposure communities. An in-home draw closes that gap, with certified filtration through retailer networks available where confirmed faucet results warrant additional measures.
