How Old Is Edgartown's Housing Stock?
With 58% 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
When a city's housing median build year is 1987, as in Edgartown, the implication for water quality research is straightforward: municipal-level data captures what leaves the treatment plant, but household plumbing from before 1986 determines what actually arrives at the tap. In cities where older housing predominates, that gap between system-level and household-level data is widest.
Over half of homes in Edgartown were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Edgartown: Remediation Cost in Perspective
For most homeowners in Edgartown, the estimated cost of water and safety remediation represents a proportionally modest share of what properties are worth - placing this area in the lower tier of the remediation share scale.
Remediation costs in Edgartown are relatively low compared to home values. The $800–$2,600 estimated range is a small fraction of median property value. Home values are 108% above the Massachusetts average.
Protecting Children from Lead in Edgartown
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.
After the federal action removing lead-bearing solder from new plumbing took effect, building practice shifted - but 58% of the Edgartown inventory predates that line. With aggregate samples near or beyond 0.015 mg/L, an in-home check moves out of the optional column into the standard list.

Historical Flood-Claim Evidence for Edgartown
Historical NFIP data for Edgartown contains 51 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $17,444. Among ZIP codes with claim records, 100% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.
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. The <strong>$1,600</strong> remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.
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.
