Housing & Infrastructure in Hudson
With 60% 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
Pre-1986 plumbing is not a rare legacy case in Hudson - it's the dominant profile. The median build year of 1988 indicates a housing stock where lead-soldered copper joints are a common structural feature of residences across the city.
Over half of homes in Hudson were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Hudson Homeowners
What does remediation cost in financial context for Hudson homeowners? Proportionally very little - the equity share here is low, and addressing documented issues is a manageable planning question rather than a material financial burden.
Remediation costs in Hudson are relatively low compared to home values. The $1,200–$3,400 estimated range is a small fraction of median property value. Home values are 12% above the New Hampshire average.
Lead Exposure Risk for Children in Hudson
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.
In recent monitoring under the Lead and Copper Rule, citywide samples for Hudson have approached or crossed the regulatory action level on multiple occasions. Combined with 60% of stock dating from the pre-rule era, the picture supports baseline single-tap reads as a standard household-level step.

Historical NFIP Claim Context in Hudson
Historical NFIP data for Hudson contains 12 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $9,963. 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>$2,200</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.
