Housing & Infrastructure in National Park
With 89% 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.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
For residents trying to assess tap water risk in National Park, the median build year of 1956 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 National Park 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 National Park Homeowners
For most National Park homeowners, estimated remediation represents a moderate equity share — manageable with planning.
Remediation costs are moderate relative to home values in National Park. The estimated $1,200–$3,400 range is manageable for most homeowners but still worth budgeting for. Home values are 57% below the New Jersey average.
Lead Exposure Risk for Children in National Park
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.
Before the federal solder ban, lead solder was a routine plumbing material, and 89% of the National Park inventory was built in that earlier era — a share large enough to move household-level reads onto the standard list.

Flood & Climate Risk in National Park
FEMA data shows 100% of National Park's ZIP codes mapped into designated flood zones, paired with an NFIP record of 70 claims. That footprint places local flood exposure in the range where it warrants attention without rising to high-severity planning territory.
National Park has a moderate flood history with 70 FEMA claims averaging $4,981 per payout. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
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>$2,200</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
