Granite Falls Infrastructure Age
With 49% of homes built before 1986, lead solder in plumbing is a potential concern. Federal law banned lead solder in drinking-water plumbing in 1986, but many older homes retain original plumbing.

Housing Age Profile
Plumbing materials follow installation dates, not medians. Granite Falls records a median build year of 1983, and a meaningful share of its homes date from before the 1986 federal lead restrictions.
Most homes in Granite Falls were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Granite Falls: Lead Risk & Vulnerable Populations
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
If you have young children or are pregnant, consider testing your home's water - especially if your home was built before 1986.

Granite Falls: NFIP Claim Records and Water-Quality Context
Historical NFIP data for Granite Falls contains 9 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $109,986. Among ZIP codes with claim records, 100% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.
How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. The $600 remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.
Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.
