Housing Age Profile
For residents trying to assess tap water risk in South Berwick, the median build year of 1987 is the starting context. It signals that a majority of homes were constructed before 1986 - the year federal rules prohibited lead solder in new plumbing - and that a significant share likely predates 1970, when lead pipes were still a common choice for residential service connections. Neither risk tier is rare in this housing inventory.
Over half of homes in South Berwick were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

South Berwick: NFIP Claim Records and Water-Quality Context
Historical NFIP data for South Berwick contains 20 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $18,672. Among ZIP codes with claim records, 0% 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>$2,400</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.
