Housing Age Profile
The story of Jadwin's housing stock is one of layered development — neighborhoods built in different decades, each carrying the plumbing standards of their era. The median build year of 1999 reflects that layered character. Before 1986, lead solder was standard in copper plumbing; before 1970, lead pipes were commonly used for service lines. A substantial portion of the pre-1986 homes visible in the distribution above still carry the plumbing materials of those earlier standards — creating a risk environment that the city-wide aggregate water data doesn't fully capture.
Most homes in Jadwin were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Jadwin: Lead Risk & Vulnerable Populations
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.
When older housing represents 44% of the local inventory or aggregate readings approach the federal action level, an in-home check becomes the standard way to translate citywide averages into the specific reality of an individual Jadwin address.

Jadwin: Flood History & Water Damage Risk
Within the NFIP's national dataset, Jadwin falls in moderate-exposure territory — 1 documented incident spanning multiple decades, with 100% of local ZIP codes sitting inside FEMA flood boundaries. That combination warrants inclusion in any thorough local water quality review.
Jadwin has a moderate flood history with 1 FEMA claims averaging $108,515 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>$2,900</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.
