Franklin Infrastructure Age
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.

Housing Age Profile
Reading the housing age data for Franklin — median build year 1955 — the overriding implication is that the plumbing materials inside a typical home here reflect pre-1986 construction standards. In practical terms, that means lead-soldered copper joints are common across much of the housing stock. Where those materials are present, water can leach lead as it moves through joints — a pathway that corrosion control treatment under federal rules is designed to reduce, though it cannot eliminate lead risk where the plumbing materials themselves contain lead.
Over half of homes in Franklin were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in Franklin
In Franklin, the equity share of documented remediation is meaningful enough to move the household financial perspective from routine maintenance into deliberate budgeting territory — the cost-to-value ratio is moderate, and most homeowners benefit from mapping the full scope against available budgets before committing.
Remediation costs are moderate relative to home values in Franklin. The estimated $800–$1,500 range is manageable for most homeowners but still worth budgeting for. Home values are 52% below the Minnesota average.
Franklin: Lead Risk & Vulnerable Populations
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.
Pulling a tap sample fills the gap that utility data cannot close, particularly here where 89% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Franklin.

What You Can Do in Franklin
- 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 89% of homes built before 1986, lead solder is a real possibility.
