Housing & Infrastructure in Falun
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Two regulatory milestones define plumbing-era risk in residential housing: 1970, when lead pipes were still commonly installed for service lines, and 1986, when lead solder was banned from new copper plumbing. A median build year of 1995 places Falun in the middle zone between those thresholds — with a meaningful share of housing predating both cutoffs. The distribution shown above breaks out those eras explicitly, clarifying where concentrated risk sits across the residential inventory.
A significant portion of Falun's housing stock predates 1970, when lead pipes were commonly used. Residents in older homes should consider water testing.

Lead Exposure Risk for Children in Falun
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 35% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Falun.

Flood & Climate Risk in Falun
Falun's NFIP record shows a low claim total — a pattern that keeps the link between flooding and water quality in the background rather than the foreground. Treatment infrastructure can be overloaded by severe flood events, but that scenario requires event frequency and magnitude that the area's claim history suggests have not materialized here.
Falun has a relatively low flood history with 1 FEMA claims on record. While risk is limited, severe weather events can still impact water infrastructure.
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. Flood damage can add significantly to the estimated <strong>$2,400</strong> remediation cost per household.
