How Old Is Dublin's Housing Stock?
With 97% 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
Lead solder was standard in copper plumbing until federally banned in 1986; lead pipes were common in service lines pre-1970. Dublin's median build year of 1945 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 Dublin were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Dublin: Remediation Cost in Perspective
The equity impact of remediation in Dublin sits at a moderate level — real enough to plan for, within reach for most.
Remediation costs are moderate relative to home values in Dublin. The estimated $800–$1,500 range is manageable for most homeowners but still worth budgeting for. Home values are 42% below the Indiana average.
Protecting Children from Lead in Dublin
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 97% pre-rule share in Dublin keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.

What You Can Do in Dublin
- Test your water at home. City-level data shows averages — your tap may differ. NSF-certified test kits cost $20-40 and give results in days.
- Install a certified water filter. An NSF-certified pitcher or under-sink filter removes most common contaminants.
- Check your home's plumbing. With 97% of homes built before 1986, lead solder is a real possibility.
