Housing & Infrastructure in Somerset
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
Because the majority of Somerset's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1972 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in Somerset 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 Somerset Homeowners
The equity-to-remediation ratio in Somerset is moderate — worth planning for but within reach for most property owners.

Lead Exposure Risk for Children in Somerset
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.
Routinely in Somerset, where 58% of housing predates the solder ban and aggregate utility readings hover near the federal threshold, a faucet-level draw functions as a standard household step for families with small kids.

Flood & Climate Risk in Somerset
While some flood zone mapping exists for Somerset, NFIP claim volume remains modest, signaling that flood events have not materially stressed local water infrastructure in the program's tracking period.
Somerset has a relatively low flood history with 2 FEMA claims on record. While risk is limited, severe weather events can still impact water infrastructure.
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. Flood damage can add significantly to the estimated <strong>$2,400</strong> remediation cost per household.
