How Old Is Unityville's Housing Stock?
With 67% 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
Two dates define the high-risk tiers of residential plumbing from a lead standpoint: 1970, before which lead pipes were commonly installed for service connections, and 1986, before which lead solder was standard in copper plumbing. A median build year of 1978 places Unityville's housing distribution well within that older risk zone. The bar chart above breaks down how much of the stock falls into each era — and the pre-1986 share alone represents more than half the residential inventory, making plumbing-era risk a defining characteristic of the local water safety picture.
Over half of homes in Unityville were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Unityville: Remediation Cost in Perspective
Is remediation financially manageable for Unityville homeowners? At a moderate equity share, generally yes — with deliberate budgeting ahead of time.
Remediation costs are moderate relative to home values in Unityville. The estimated $1,600–$3,300 range is manageable for most homeowners but still worth budgeting for. Home values are 5% above the Pennsylvania average.
Protecting Children from Lead in Unityville
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.
Wherever 67% of local housing was built before solder rules changed — as is the case in Unityville — a faucet-level sample closes the gap that aggregate utility data cannot.

Climate-Related Water Risk for Unityville
A moderate NFIP record for Unityville — 3 insurance claims paired with 100% of ZIP codes in FEMA flood zones — points to a flood history where water-quality pathways have likely been periodically relevant.
Unityville has a moderate flood history with 3 FEMA claims averaging $8,058 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>$2,400</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.
