Housing & Infrastructure in Niagara
With 98% 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
When more than half a city's housing predates the 1986 federal ban on lead solder, plumbing-era lead risk becomes a citywide concern rather than an exception. Niagara's median build year of 1944 places it squarely in that category.
Over half of homes in Niagara 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 Niagara Homeowners
Remediation costs in Niagara represent a moderate share of typical home values — worth budgeting for carefully, though within reach for most homeowners who plan ahead.
Remediation costs are moderate relative to home values in Niagara. The estimated $800–$1,500 range is manageable for most homeowners but still worth budgeting for. Home values are 50% below the North Dakota average.
Lead Exposure Risk for Children in Niagara
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 98% pre-rule share in Niagara keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.

What You Can Do in Niagara

- Check your home's plumbing. With 98% of homes built before 1986, lead solder is a real possibility.
