How Old Is Langlois's Housing Stock?
With 60% 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.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Federal plumbing rules changed in two stages — lead pipes were phased out before 1970, and lead solder was banned in 1986 — but in Langlois, where the median build year is 1975, most of the housing was already in place before those rules took effect. The materials installed under older standards remain embedded in a substantial portion of the residential inventory today.
Over half of homes in Langlois were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Langlois: Remediation Cost in Perspective
Remediation costs in Langlois are small relative to typical property values — the cost-to-value ratio here is favorable.
Remediation costs in Langlois are relatively low compared to home values. The $1,100–$3,300 estimated range is a small fraction of median property value. Home values are 18% below the Oregon average.
Protecting Children from Lead in Langlois
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.
Wherever 60% of local housing was built before solder rules changed — as is the case in Langlois — a faucet-level sample closes the gap that aggregate utility data cannot.

Climate-Related Water Risk for Langlois
Langlois's flood exposure sits in the moderate range: 3 NFIP claims on record and 100% of ZIP codes within FEMA-designated flood zones. Residents with private wells or older infrastructure have reasonable grounds to factor flood timing into their water quality awareness.
Langlois has a moderate flood history with 3 FEMA claims averaging $1,309 per payout. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
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>$1,800</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
