Housing & Infrastructure in Norwich
With 78% 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
What does a median build year of 1956 mean for water safety in Norwich? It means the majority of the city's residential plumbing was installed before 1986, when lead solder was federally banned, and a large share may predate 1970, when lead pipes were commonly used — making plumbing age a central variable in household-level lead risk across much of the city.
Over half of homes in Norwich 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 Norwich Homeowners
Homeowners in Norwich are working with a moderate equity share for documented remediation — the commitment deserves a line in the household budget, not dismissal.
Remediation costs are moderate relative to home values in Norwich. The estimated $950–$2,100 range is manageable for most homeowners but still worth budgeting for. Home values are 29% below the Kansas average.
Lead Exposure Risk for Children in Norwich
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.
If 78% of the Norwich inventory comes from before the federal ban on lead-bearing solder — and if utility samples sit at or near 0.015 mg/L — the gap between citywide averages and one specific faucet becomes a practical concern rather than a theoretical one. That is why one-home reads exist as a separate measurement. A certified filter through retailer networks addresses confirmed exposure where it appears in a household.

What You Can Do in Norwich
- 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. Filters rated for Total Trihalomethanes (TTHM) can reduce the most common contaminant found in Norwich's water.
- Check your home's plumbing. With 78% of homes built before 1986, lead solder is a real possibility.
