Housing Age Profile
Pre-1986 plumbing is not a rare legacy case in Theresa — it's the dominant profile. The median build year of 1970 indicates a housing stock where lead-soldered copper joints are a common structural feature of residences across the city.
Over half of homes in Theresa 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 Theresa
Given current Theresa valuations, the remediation-to-property-value ratio is low — most homeowners are looking at a proportionally modest share that fits within routine financial planning.
Remediation costs in Theresa are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 56% below the New York average.
Theresa: 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 58% of Theresa 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.
