Housing Age Profile

Lead solder was standard in copper plumbing until federally banned in 1986; lead pipes were common in service lines pre-1970. Nunda's median build year of 1941 reflects a housing stock where these older materials are a pervasive feature - not a rare legacy - of the residential plumbing landscape.

Cost Context: What Remediation Means for Nunda Homeowners

How does remediation fit within the broader financial picture for Nunda homeowners?

Lead Exposure Risk for Children in Nunda

mg/L Avg Lead (Limit: 0.015)

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 69% pre-rule share in Nunda keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.
