Housing & Infrastructure in Armagh
With 70% 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
Lead solder was standard in copper plumbing until federally banned in 1986; lead pipes were common in service lines pre-1970. Armagh's median build year of 1976 reflects a housing stock where these older materials are a pervasive feature — not a rare legacy — of the residential plumbing landscape.
Over half of homes in Armagh 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 Armagh Homeowners
What does remediation cost in financial context for Armagh 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 Armagh are relatively low compared to home values. The $1,200–$2,300 estimated range is a small fraction of median property value. Home values are 13% below the Pennsylvania average.
Lead Exposure Risk for Children in Armagh
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.
Even where utility-side monitoring meets Lead and Copper Rule requirements, the 70% pre-rule share in Armagh keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.

What You Can Do in Armagh

- Check your home's plumbing. With 70% of homes built before 1986, lead solder is a real possibility.
